GNU / Linux and other Free as in Beer OS-es such FreeBSD and OpenBSD as well as other UNIX variants are definitely not the best platform to do Video edit, as the best one is obviosuly MAC OS-es for being a veteran in the field of graphic edit for a long time but over the time its capabilities are slowly but surely evolving.
However Linux users can also do the basic video edit stuff quite easily with ffmpeg and few other tools.
The general things one faces when snapshotting videos is the video might be turned around or in the wrong angle and you want it to rorate, or you have two three or more video files and you would like to merge the ones in one or you would like to Trim a period in the beginning of a Video or Trim some time you don't need out of the video at the end end, merge multiple MP3 files into single recording or including a background music to a video.
Doing such a things has a lot of possibilities with tools such as ffmpeg, imagemagick and mencoder and it is mostly useful if you're a console guy or you need to write a program that does video rorate or video merge in PHP / Perl / Python etc.
1. Rotating Videos in Linux
Rotate a Video in 90 degrees
Rotating a video assuming that you have the ffmpeg tool installed is as easy as:
# ffmpeg -i in-video-file.mov -vf "transpose=1" out-video-file.mov
Supported value arguments for ffmpeg ranspose option
0 = 90CounterCLockwise and Vertical Flip (default)
1 = 90Clockwise
2 = 90CounterClockwise
3 = 90Clockwise and Vertical Flip
2. Flip the video clip Vertically
# ffmpeg -i out.mov -vf "vflip" out2.avi
If you don't have ffmpeg, just install it with apt or yum:
On Debian
# apt install –yes fmpeg
On Redhat based distros
# yum install -y ffmpeg
ffmpeg is easily installed by bsd ports with the package manager for example on FreeBSD it is up to :
# pkg install ffmpeg
3. Merge (Concatenating) Videos with ffmpeg / mencoder / avimerge on Linux
Go to the directory containing all the videos you would like to merge and merge them with belowsimple one liner:
# ffmpeg -f concat -i \
<(for f in $PWD/*.avi;do echo "file '$f'";done) \
-c copy output.avi
To merge multiple set of lets say ( sequential ) Video files on Linux with mencoder and produce a single video file:
# mencoder -oac copy -ovc copy 1.AVI 2.AVI 3.AVI 4.AVI -o Single-common-out-video.avi
mencoder is available also by default on most distros if not install it with:
On Deb based Linuz:
# apt install mencoder –yes
On Fedora / CentOS … rpm based:
# yum install -y mencoder
The old and now obsolete transcode audio / video converter could also be used:
# avimerge -i file-input1.avi file-input2.avi -o output-file.avi
4. Scaling a video to a concrete resolution
It might happen to you that some video files could not be concatenated with other video file because its resolution is smaller (or different) than the recorded material,
to come around this you need to scale it.
# Scale video resolution to 1920×1080 pixels
# ffmpeg -i input-video.mp4 -vf scale=1920:1080 output-video.mp4
5. Trimming the beginning of a Video with ffmpeg
A recording will often contain parts in the beginning that you don't need and have to beto be removed from the video stream:
# Remove the first three seconds (Common scenario)
# ffmpeg -i input.mp4 -ss 3 -c copy output.mp4
6. Trimming the end of MP4 video with ffmpeg
The same is true for the end of a video materials often:
# Remove everything after 5 minutes and 32 seconds
#ffmpeg -i input.mp4 -t 00:05:32 -c copy output.mp4
Both, -ss and -t, can also be combined into one command.
7. Adding Background Music to a Video with ffmpeg
To add a concrete background music to a video stream, track the volume had to be lowered first:
7.1 Reduce the volume MP3 music file by 50% with ffmpeg
# ffmpeg -i input.mp3 -filter:a "volume=0.5" output.mp3
7.2 Combine multiple audio tracks into one single recording stream
# Concatenate multiple mp3 voice files into one
# ffmpeg -i "concat:input-song1.mp3|input-song2.mp3|input-song3.mp3" -c copy output-concatenated-single-song.mp3
One thing to consider is that once you want to add a background music stream to a video stream, both the video and the song has to be of the same length, otherwise attempts to merge the background audio track with fail
due to the length of the audio track not matching the length of the video.
This can be resolved by generating a silent audio track and concatenating it to the end of the audio track to make the video and music match:
# Generate 33 seconds of silence
# ffmpeg -f lavfi -i anullsrc=channel_layout=5.1:sample_rate=48000 -t 33 output.mp3
Finally, to merge the audio track into the video track:
# Merge video with existing audio track and another audio track
# ffmpeg -i input.mp4 -i input.mp3 -filter_complex "[0:a][1:a]amerge=inputs=2[a]" -map 0:v
Sum it up what learned
In this article was shown how to convert multiple Videos into a single one, scaling a video to a graphics resolution, trip a video at the beginning and at the end, add background movie tracks as a sound on Linux.
As you can imagine this stuff is quite useful and used by many, many websites online to do a different Video and sound editing included in a millions of Frontend / Backend webscritt Scripts around silently doing its stuff.
There is much more to be done with this tools, but for a starter of a video edit newbies it should on Linux and enthusiasts to manage own managed small private clouds, hope this stuff will be useful for a introductionary.
Cheers ! 🙂

I've been given a very tedious task to Copy music from Audio CD Drive to MP3 / MP4 file format and then copy the content to external Flash drive.
Doing so is pretty trivial, you just need to have a CD / DVD rom on your computer something that becomes rare nowadays and then you need to have installed a bunch of software, if you don't already have it as i've pointed in my previous article Howto craete Music Audio CD from MP3 files, create playable WAV format audio CD Albums from MP3s.
Creating a Audio CD from an MP3 collection is exactly the opposite to what is aim't now (to copy the content of a CD to a computer and prepare it for A Car MP3 player).
1. RIPing audio CDs to WAV and Conver to MP3 from terminal
On Linux there is many ways to do it and many tools that can do it for your both graphical and command line.
But as I prefer command line to do stuff, in this article I'll mention the quickest and most elementary one which is done in 2 steps.
1. Use a tool to dump the CD Audio music to Tracks in WAV format
2. Convert the WAV to MP3 format
We'll need cdparanoia tool installed as well as ffmpeg.
If you don't have them installed do:
# apt-get install –yes cdparanoia dvd+rw-tools cdw cdrdao audiotools cdlabelgen dvd+rw-tools wodim ffmpeg lame normalize-audio libavcodec58
Next create the directory where you want to dump the .wav files.
# mkdir /home/hipo/audiorip/cd1
# cd /home/hipo/audiorip/cd1
Next assumng the Audio CD is plugged in the CD reader, dump its full content into track*.WAV files with cmd:
# paranoia -B
This will produce you the dumped songs into .wav files.
hipo@noah:~/audiorip/cd1$ ls -al *.wav
-rw-r–r– 1 root root 10278284 мар 25 22:49 track01.cdda.wav
-rw-r–r– 1 root root 21666668 мар 25 22:50 track02.cdda.wav
-rw-r–r– 1 root root 88334108 мар 25 22:53 track03.cdda.wav
-rw-r–r– 1 root root 53453948 мар 25 22:55 track04.cdda.wav
-rw-r–r– 1 root root 100846748 мар 25 22:58 track05.cdda.wav
-rw-r–r– 1 root root 41058908 мар 25 22:59 track06.cdda.wav
-rw-r–r– 1 root root 105952940 мар 25 23:02 track07.cdda.wav
-rw-r–r– 1 root root 50074124 мар 25 23:03 track08.cdda.wav
-rw-r–r– 1 root root 92555948 мар 25 23:06 track09.cdda.wav
-rw-r–r– 1 root root 61939964 мар 25 23:07 track10.cdda.wav
-rw-r–r– 1 root root 8521340 мар 25 23:07 track11.cdda.wav
Then you can use a simple for loop with ffmpeg command to conver the .wav files to .mp3s.

Finally remove the old unneded .wav files and enjoy the mp3s with vlc / mplayer / mpg123 or whatever player you like.
hipo@noah:~/audiorip/cd1$ rm -f *.wav
Now mount the flash drive and copy th files into it.
# mkdir /media/usb-drive
# mount /dev/sdc1 /media/usb-drive/
# mkdir -p /media/usb-drive/cd1
# fdisk -l |grep -i sdc1

2. RIPping audio CD on Linux with rip-audio-cds-linux.sh script
#!/bin/bash
# A simple shell script to rip audio cd and create mp3 using lame
# and cdparanoia utilities.
# —————————————————————————-
# Written by Vivek Gite <http://www.cyberciti.biz/>
# (c) 2006 nixCraft under GNU GPL v2.0+
# —————————————————————————-
read -p "Starting in 5 seconds ( to abort press CTRL + C ) " -t 5
cdparanoia -B
for i in *.wav
do
lame –vbr-new -b 360 "$i" "${i%%.cdda.wav}.mp3"
rm -f "$i"
done
If you need to automate the task of dumping the audio CDs to WAV and convert them to MP3s you can do it via a small shell script like the one provided by cyberciti.biz that uses paranoia and lame commands in a shell script loop. Script rip-audio-cds-linux.sh is here
3. Dump Audio CD to MP3 with Graphical program ( ripperx )
By default most modern Linux distributions including the Debian GNU / Linux based ones has the ripperx in the default repositories, as well as the tool is downloadable and compilable from source from sourceforge.net
# apt-cache show ripperx|grep -i descript -A3 -B3
Architecture: amd64
Depends: cdparanoia, vorbis-tools (>= 1.0beta3), libatk1.0-0 (>= 1.12.4), libc6 (>= 2.14), libcairo2 (>= 1.2.4), libfontconfig1 (>= 2.12.6), libfreetype6 (>= 2.2.1), libgcc1 (>= 1:3.0), libgdk-pixbuf2.0-0 (>= 2.22.0), libglib2.0-0 (>= 2.16.0), libgtk2.0-0 (>= 2.8.0), libpango-1.0-0 (>= 1.14.0), libpangocairo-1.0-0 (>= 1.14.0), libpangoft2-1.0-0 (>= 1.14.0), libstdc++6 (>= 5.2), libtag1v5 (>= 1.9.1-2.2~)

If you're on Linux the questions like, how can I convert between video and audio formats, how to do photo editing etc. etc. have always been a taugh question as with it's diversity Linux often allows too many ways to do the same things.
In the spirit of questioning I have been recently curious, how can a subtitles be added to a flash video (.flv) video?
After some research online I've come up with the below suggested solution which uses mplayer to do the flash inclusion of the subtitles file.
mplayer your_flash_movie.flv -fs -subfont-text-scale 3
While including the subtitles to the .flv file, it's best to close up all the active browsers and if running something else on the desktop close it up.
Note that above's mplayer example for (.srt and .sub) subtitle files example is only appropriate for a .flv movie files which already has a third party published subtitle files.
What is interesting is that often if you want to make custom subtitles to let's say a video downloaded from Youtube on Linux the mplayer way pointed above will be useless. Why?
Well the Linux programs that allows a user to add custom subtitles to a movie does not support the flv (flash video) file format.
My idea on how to create custom subtitles and embed them into a flv movie file is very simple and it goes like this:
1. Convert the .flv file format to let's say .avi or .mpeg
2. Use gnome-subitles or subtitleeditor to create the subtitles for the .avi or .mpeg file
3. Convert back the .avi/.mpeg file with included subtitles to .flv (flash video format)
This methodology is really long and time consuming, but pitily as far as my understanding goes it's the only way to do that on your Linux until now.
To make the conversations between .flv and .avi format you will need to use the ffmpeg – (FFMpeg command line tool video converter), here is how:
– Convert .flv to .avi
debian:~# /usr/bin/ffmpeg -i input_flvfilename.flv output_avifilename.avi
– Convert .avi file to .flv
debian:~# /usr/bin/ffmpeg -y -i /path/to/your/avi/input_avifilename.avi -acodec mp3 -ar 22050 -f flv
/path/to/your/flv/output_flvfilename.flv
The required overall tools which you will have to have installed on your Debian or Ubuntu Linux are:
1. ffmpeg
2. gnome-subtitles
3. subtitleeditor
4. mplayer
You will also have to spend some time to get to know gnome-subtitles or subtitleeditor, but it won't be that long until you get the idea on how to use them.

Here in my job, there is one internet (TV) around which can only read video formats in Mp4. Henceforth I needed a way to convert a number of JPEG / PNG format Picture files to Mp4. In my situation I needed to make video out of pictures and script it as this was required to be later pushed via FTP protocol to the Internet TV. Ater doing some research I figured out this is possible to build video out of pictures by using together ImageMagick and avconv.
First thing is to send pictures in certain resolution. There is a tool from imagemagick package called mogrify (which can do that). To convert a number of different dimension pictures to lets say 1024×768, used:
noah:~# mogrify -resize 1024×768 *.png
In earlier Linux distributions to create a movie from pictures ffmpeg was used like so:
# ffmpeg -qscale 5 -r 20 -b 9600 -i SDC%04d.png movie.mp4
However in newer version of ffmpeg support for this is removed, and to make video from images, there is other tool avconv. On most Linux distributions avconv is part of libav-tools package.
To install on avconv Debian and Ubuntu;
noah:~# apt-get install –yes libav-tools
…
Once installed to create single mp4 video from JPEG or PNG pictures:
noah:~# avconv -i SDC106001.JPG SDC10595.JPG SDC13611.JPG SDC13612.JPG SDC13614.JPG movie-from-pictures.mp4
I found there is also a nice GUI,software Open Movie Editor, which can create video out of number of pictuers stored in a directory.
Open Movie Editor is available in most Linux distributions (unfortunately as of time of writting on Debian Wheeze there is no install candidate of openmovieeditor), there is however substitute package doing the same job called openshot);
On latest Debian stable to install Openshot:
noah:~# apt-get install –yes openshot
Openshot has an option (Import Image Sequence) from File -> Import Image Sequence. Using this option you can select a directory with fles with common prefix name lets say IMG*.png and create Video based on the photos inside.
On Ubuntu Linux or other distro where openmovieeditor is avialable install it with:
ubuntu:~# apt-get install –yes openmovieeditor
…
To create a video out of pictures click on Media Browser tab. Choose the Folder with pictures from which video will be generated and drag them to the Video bar
(window).
To save produced video navigate to menus:
Project -> Render
and select format to save it as. One good codec to save output is Quicktime's. To convert later Quicktime MOV Video to MP4 video,
there is the Pytube Media Converter script.
Well that's all enjoy your new videos from pictures 🙂

Friday, April 8th, 2011 I needed to convert a bunch of files from WAV to MP3 format on my Linux desktop.
I’ve placed all my wav files to the directory /home/hipo/wav
And then I issued the small one liner script to convert the .wav files to .mp3 using the niftly lame linux mp3 convertor.
Here is how I did it:
linux-desktop:~$ cd wav
linux-desktop:/home/hipo/wav$ for i in *.wav; do
new_name=$(echo $i |sed -e 's#wav#mp3#g');
lame -V0 -h -b 160 --vbr-new "$i" "$new_name";
done
After executing the little script you might go and have a coffee, if you have thousands of files, each file convertion takes about 10-15 seconds of time (speed depends on your CPU).
Here is some output from a lame convertion to mp3 taking place:
Encoding as 8 kHz single-ch MPEG-2.5 Layer III VBR(q=0)
Frame | CPU time/estim | REAL time/estim | play/CPU | ETA
27237/27237 (100%)| 0:12/ 0:12| 0:12/ 0:12| 155.89x| 0:00
64 [27237] ***************************************************************
----------------------------------------------
kbps mono % long switch short %
64.0 100.0 84.1 8.9 7.0
If you want to save my convertion quickly for a later, download my Convert WAV to mp3 from a directory with lame shell script here
Actually there are plenty of other ways to convert wav to mp3 on Linux through mplayer, ffmpeg even with mpg123.
There are also some GUI programs that could do the convertion like winff , however for some weird reason after installing WinFF on my debian it was not able to complete convertion to mp3?!
But it doesn’t matter, the good news is I did what I wanted to via the simple lame program and the above script, hope it helps somebody out there.

Tuesday, December 25th, 2012 The good old ffmpeg, along with being able to capture sound and video from your Linux Desktop or a certain Window and Skype whatever WebCamera input is also able to record sound from both camera or embedded laptop microphone. Here is how:
# ffmpeg -f alsa -ac 2 -i pulse -acodec pcm_s16le -vcodec libx264 -vpre lossless_ultrafast -threads 0 -y myVOICE.wav
This as you can see from arguments, uses GNOME's pulseaudio (audio service) and ALSA. Sound is first streamed through alsa and then the sound inflow is passed to be processed and multipled in a separate sound channel by pulseaudio. This method though said to be working fine on Ubuntu Linux is not working well on some other Linux distributions like Debian if one is using ALSA configured to use a software sound multiplexor via the so called – alsa dsnoop interface (previously I write how to use it in order to make Skype and other programs use SoundBlaster proper – article is here)
Below is the output warning I got whether trying ffmpeg with -f alsa and -i pulse arguments:
hipo@noah:~/Desktop$ ffmpeg -f alsa -ac 2 -i pulse -acodec pcm_s16le -vcodec libx264 -vpre lossless_ultrafast -threads 0 -y myVOICE.wav

where concrete programs, are run which take use of OSS (Open Sound System) – an already obsolete sound architecture. By the way on current Debian / Fedora etc. Linux-es OSS is managed and played only, whether few kernel modules are already pre-loaded, below are the ones as pasted from my Debian Squeeze:
# lsmod | grep -i oss
snd_pcm_oss 32591 0
snd_mixer_oss 12606 1 snd_pcm_oss
snd_pcm 60487 3 snd_hda_intel,snd_hda_codec,snd_pcm_oss

The oss processed sound recording from ffmpeg is not working, well on my Linux, cause I have my custom (non-Debian) native binary Firefox downloaded and installed from Firefox's website.The browser is compiled to open automatically /dev/dsp which in practice uses the above-mentioned OSS listed modules, which on their behalf when used break out the sound processed by alsa and respectively pulseaudio (those who use Linux for longer time should remember in the times of OSS only one certain sound stream was possible to be processed / played on Linux historically before ALSA come to scene to be "defacto" standard kernel sound processor. Well ofcourse firefox developers who compiled the Firefox for Linux probably was using Slackware or some other Linux distro which probably used to play sound still via OSS or maybe they compiled it so thinking OSS because of its historical importance is still supported by more Linux distributions than alsa is. I like the custom compiled Firefox to run on my Debian instead of default Debian Squeeze (IceWeasel) cause firefox.org ,Firefox version is much newer and supports better latest HTML5 as well as it includes ability to download and apply automatic updates to the latest version provided by Firefox team. However I fou
Thus for Linux users like me using latest firefox binary from firefox.org (in parallel) with opened Firefox browser to record sound from Webcam or Embedded notebook mic the obsolete OSS has to be used, here is how:
# ffmpeg -f oss -ac 2 -i /dev/dsp -acodec pcm_s16le -vcodec libx264 -vpre lossless_ultrafast -threads 0 -y my-recorder-VOICE.wav
Enjoy ;)

Two articles, before I've blogged on how one can take pictures from console / terminal with ffmpeg. It was interesting fact, I've stumbled on ffmpeg is able of capturing video executed from terminal or plain console TTY.
The command to do so is:
# ffmpeg -f video4linux2 -r 25 -s 640x480 -i /dev/video0 webcam-movie.avi
FFmpeg version SVN-r25838, Copyright (c) 2000-2010 the FFmpeg developers
built on Sep 20 2011 17:00:01 with gcc 4.4.5
configuration: --enable-libdc1394 --prefix=/usr --extra-cflags='-Wall -g ' --cc='ccache cc' --enable-shared --enable-libmp3lame --enable-gpl --enable-libvorbis --enable-pthreads --enable-libfaac --enable-libxvid --enable-postproc --enable-x11grab --enable-libgsm --enable-libtheora --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libx264 --enable-libspeex --enable-nonfree --disable-stripping --enable-avfilter --enable-libdirac --disable-decoder=libdirac --enable-libschroedinger --disable-encoder=libschroedinger --enable-version3 --enable-libopenjpeg --enable-libvpx --enable-librtmp --extra-libs=-lgcrypt --disable-altivec --disable-armv5te --disable-armv6 --disable-vis
libavutil 50.33. 0 / 50.43. 0
libavcore 0.14. 0 / 0.14. 0
libavcodec 52.97. 2 / 52.97. 2
libavformat 52.87. 1 / 52.87. 1
libavdevice 52. 2. 2 / 52. 2. 2
libavfilter 1.65. 0 / 1.65. 0
libswscale 0.12. 0 / 0.14. 1
libpostproc 51. 2. 0 / 51. 2. 0
Like you can see in accordance with WebCamera maximum supported resolution, one can change 640×480 to higher in case if attached expensive HD webcam.
Note that the webcamera should not be in use when issuing the command, otherwise because /dev is used you will get:
[video4linux2 @ 0x633160] Cannot find a proper format for codec_id 0, pix_fmt -1. /dev/video0: Input/output error
It is another interesting, topic I thought if if i t is possible to somehow caputre the Video streamed currently, whether for example in Skype there is a Skype conference established, but unfortunately it is not possible to do it with ffmpeg, cause /dev/video0 is in use while Skype Video stream flows.
There is another way to record Skype and other Programs recording from the WebCam (i.e. Cheese) by using a small command line tool recordmydesktop.
To use recordmydesktop to save (record) Skype Video Conference just run it in advance and afterwardsmake your Skype call. To capture input from the WebCam while it is in use there are two other GUI instruments capturing the Active Desktop – e.g. Istanbul and vnc2swf. If you never used any of those and you want to read short review on them check out my older article – Best Software Available Today for GNU / Linux Desktop capturing on Debian
The The little problem with recording the desktop is that if you want to record the Skype conference and straight use the software you will catch also the rest of the Desktop, however it is possible to set recordmydesktop to record content from a Windows with specific ID, so recording only skype Video should be possible too.
I was intrigued by the question if after all Video Capturing is possible while Video is Streamed from WebCam with ffmpeg, so did a quick research for the command line freaks, here is how:
ffmpeg -f x11grab -s `xdpyinfo | grep -i dimensions: | sed 's/[^0-9]*pixels.*(.*).*//' | sed 's/[^0-9x]*//'` -r 25 -i :0.0 -sameq recorder-video-from-cam.avi
The only problem with this command line is the video captured from webcamera will be without sound. To take the Video and Sound input with ffmpeg use:
ffmpeg -f alsa -ac 2 -i pulse -f x11grab -r 30 -s 1024x768 -i :0.0 -acodec pcm_s16le -vcodec libx264 -vpre lossless_ultrafast -threads 0 mydesktop.mov
On Debian and Ubuntu Linux, there is also GUI recordmydesktop the package name to install is gtk-recordmydesktop. GTK-RecordMyDesktop, works pretty well, so probably for people looking for convenience and ex-Windows GUI oriented Linux
users it is best choice.
To use it on Debian:
# apt-get --yes install gtk-recordmydesktop
and launch it with cmd:
# gtk-recordmydesktop
As you can see in above, screenshot GTK-Screenshot can select a Certain Window on Desktop to record, so with it it is a piece of cake to:
1. start the Skype Video conference
2. Launch gtk-recordmydesktop
3. Press Select Window and Select Skype Video Stream
I'm curious if the pointed Skype + gtk-recordmydesktop, method to capture Skype Active videos will be working on FreeBSD. Unfortunately I don't have FreeBSD Desktop with attached WebCam to give it a, try I will be very thankful, if someone using FreeBSD / NetBSD happen to read this article and take few minutes to test if it works and drop a comment below.
That's all, Enjoy, your captured video with sound 😉

Friday, July 27th, 2012 I’ve used K3B just recently to RIP an Audio CD with music to MP3. K3b has done a great job ripping the tracks, the only problem was By default k3b RIPs songs in OGG Vorbis (.ogg) and not mp3. I personally prefer OGG Vorbis as it is a free freedom respecting audio format, however the problem was the .ogg-s cannot be read on many of the audio players and it could be a problem reading the RIPped oggs on Windows. I’ve done the RIP not for myself but for a Belarusian gfriend of mine and she is completely computer illiterate and if I pass her the songs in .OGG, there is no chance she succed in listening the oggs. I’ve seen later k3b has an option to choose to convert directly to MP3 Using linux mp3 lame library this however is time consuming and I have to wait another 10 minutes or so for the songs to be ripped to shorten the time I decided to directly convert the existing .ogg files to .mp3 on my (Debian Linux). There are probably many ways to convert .ogg to mp3 on linux and likely many GUI frontends (like SoundConverter) to use in graphic env.
I however am a console freak so I preferred doing it from terminal. I’ve done quick research on the net and figured out the good old ffmpeg is capable of converting .oggs to .mp3s. To convert all mp3s just ripped in the separate directory I had to run ffmpeg in a tiny bash loop.
A short bash shell script 1 liner combined with ffmpeg does it, e.g.;
for f in *.ogg; do ffmpeg -i "$f" "`basename "$f" .ogg`.mp3"; done.....
The loop example is in bash so in order to make the code work on FreeBSD it is necessery it is run in a bash shell and not in BSDs so common csh or tcsh.
Well, that’s all oggs are in mp3; Hip-hip Hooray 😉

Thursday, September 29th, 2011 ffmpeg is the de-facto standard for Video conversion on Linux and BSD platforms. I was more than happy to find out that ffmpeg is capable of converting an .ogv file format to .flv (Flash compressed Video).
Ogg Vorbis Video to Flash’s conversion on Linux is a real piece of cake with ffmpeg .
Here is how to convert .ogv to .flv:
debian:~# ffmpeg -i ogg_vorbis_video_to_convert_.ogv converted_ogg_vorbis_video_to_flash_video.flv
...
Conversion of a 14MB ogg vorbis video to flv took 28 seconds, the newly produced converted_ogg_vorbis_video_to_flash_video.flv has been reduced to a size of 9MB. This is on a system with 2 GB of memory and dual core 1.8 Ghz intel CPU.
