Free convert video files software for linux

3gp converter is a GUI (Kommander script) that uses ffmpeg as a backend and allows you convert the video files in 3gp format, which used at mobile phones.
You must have ffmpeg installed at you system compilled with AMR audio-codec fupport (check up ffmpeg manuals for instructions). Also you need Kommander installed(at least kommender executor).
You can set custom parameters of encoding,for video stream: resolution, bitrate, framerate, used codec (h263,mpeg4), one or two pass encoding.
For audio stream:bitrate,samplerate (AAC only), audio codec (amr_nb,AAC).
Enhancements:
- updated homepage and added some info
- sliders fix (now sliders moves when you set values manually)
- added prevew backend switch(ffplay/mplayer)
- added "exit" button
- added "stop" buttons for prevew

av_convert consists of some tools for the manipulation of video files.
In more detail av_rec can capture live video and audio from any v4l framegrabber device. The program av_convert can convert between some video file formats and provide basic editing functions.
This includes extracting arbitrary parts out of different video files and combining them in one destination file. Information about videos, such as length and contained audio and video streams can be obtained by av_info.
All the functionality needed for accessing the audio and video stored in file containers is provided by a library (libVideoFile). This functionality includes frame exact positioning in the audio and video streams and decoding/encoding of the compressed data stored in the files.
The different file types and audio/video codecs are handled by individual plugin modules. These I/O backends and codecs are loaded by libVideoFile at runtime. For now, there are plugins for the most important file formats like AVI (including extension for large files), Quicktime, MPEG/DVD, YUV4MPEG stream, WAV, mp3, etc.
Enhancements:
- Compatibility with gcc 4.0 and SPARC64/Linux was improved.

Download Youtube video is a Konqueror service menu to download and encode youtube videos.
This is a hack of another service menu that stoped working (at least for me): http://www.kde-apps.org/content/show.php?content=37509
Main features:
- Download videos with the KDE file copy dialog instead of using KGet
- Automatically encode videos with mencoder, or just download
You can use ffmpeg too, just comment out the right lines in the python file, Im unable to encode some videos with ffmpeg, so mencoder is the default

Linux Video Maker is useful for DVD/(S)VCD structure generating, ready for record on CD/DVD. Its in fact graphics interface (GUI) for transcode, mplex, DVDAuthor and few other programs...

Using of these programs for this purpose is uncomfortable and sometimes difficult especially for beginners because it involves a lot of knowledge about DVD/(S)VCD technology and video converting.

Linux Video Maker binds funcionality of 8 exterior programs and prevents from making many mistakes mainly in conversion process which can take a lot of time as AVI files uses complicated video algorithms (DIVX).

Program doesnt contain yet too many advanced options but it allow generate a standard DVD/(S)VCD structure without any problems.

Program in 2 GUI languages: english and polish !

iPod Video Encoder is a command line tool for convenient encoding of video files for use on iPod video. iPod Video Encoder project uses the ffmpeg tool for the actual encoding.

It can be used in a cron job that periodically checks directories for new files and encodes them without user intervention.
Main features:
- Encoding of single files
- Optional specification of a/v bitrates
- Recursively encode all files in a directory
- Generating a podcast.xml for convenient use in iTunes
Options:
--version show programs version number and exit
-h, --help show this help message and exit
-R, --recursive Process directories recusively
-f, --force Force re-encode existing iPod videos
-t, --test Only encode first 10 seconds, to produce test videos
-e EXTENSIONS, --extensions=EXTENSIONS
Comma separated list of input extensions. Default: avi
-i IPODEXT, --ipodext=IPODEXT
iPod extension. Default: .ipod.mp4
-b VIDEO_RATE, --video-rate=VIDEO_RATE
Video bit rate, in kbps (default: 1024)
-a AUDIO_RATE, --audio-rate=AUDIO_RATE

-W WIDTH, --width=WIDTH
Video width, in pixels (default: 320)
-H HEIGHT, --height=HEIGHT
Video height, in pixels (default: 240)
-P, --pretend Do not really encode, just print out the ffmpeg
commands which would be executed

thin liquid film project is an application which allows linux users to quickly and easily convert video files into a format suitable for playing on the video capable ipods. I wrote this application, after purchasing a video ipod, and being frustrated that the only real option for converting video was either via command-line, or via a servicemenu with no ability to configure the resulting video file.
TLF uses the ffmpeg engine to do the encoding. It is written in pyqt, so it should work with a default kde installation, and is very easy to install.

Who to use it with Firefox:

Now I will explain you how to get it working with Firefox,

First we need a Firefox extension called: Lanchy,
this extension give us the ability to open directly from Firefox Youtube video on youtube webpage (not on all webpages that have a youtube video!

You ALWAYS need the youtube videos webpage! After you have installed Launchy (from firefoxs addon site), restart Firefox, now it will ask you to insert a Launchys button on your toolbar (DO IT! so open Youtube videos will be very simply), after that go on the preferences/option of this extension and uncheck the option: "search automatically programs".

Now copy the "launchy.xml" file that you found on the package and copy it on your directory:
".mozilla/firefox/YOUR_ID.default/chrome/" , after copied it, please dont forget to edit it with your myvs.py COMPLETE PATH, and add or delete oppurtune option to pass to the script.

Now restart again firefox an watch if it recognise the command (by pressing the G).

Go on youtube.com, open a video webpage, click on the G button-> Open in Mplayer Youtube Video Streamer.
