Sinthgunt is a graphical user interface for ffmpeg, a program that can convert digital audio and video into numerous formats. It is easy to use, and has more than 100 pre-configured conversion settings. It automatically detects which presets are supported by your version of ffmpeg. It is easy to extend, since the conversion settings are stored in an XML file.
AstroAviBrowser is a small tool for astronomy imaging capture/processing. It allows you to open a video file, select the good frames, and save the new sequence in a new avi file using raw or lossless codecs. You may also de-bayer your frames and separate RGB plans. It's a kind of "AviRaw" for Linux.
FFmpegPHP is a pure OO PHP port of the ffmpeg-php wrapper. It adds an easy to use, object-oriented API for accessing and retrieving information from video and audio files. It has methods for returning frames from movie files as images that can be manipulated using PHP's image functions. This works well for automatically creating thumbnail images from movies. It is also useful for reporting the duration and bitrate of audio files (MP3, WMA, etc.). It can access many of the video formats supported by ffmpeg, including MOV, AVI, MPG, and WMV.
typhon is a slim and themeable OpenGL-based frontend, dashboard, and program launcher. It's meant to be easily used on Linux HTPCs, but also works on standard desktops or as netbook launcher. It has picture support for background, icons, stencils, and preview pictures. There's also an optional auto-screenshot mode that creates a preview picture of the launched app after a user-configured time. It also has a built-in OpenGL ffmpeg video player, which can be used to video preview programs and emulators/ROMs or simply to watch some movies. The video and everything else can be rotated into any direction and the position can be saved. Everything can be configured by the user, including colors, whole color themes, font, font size (any TTF font will do), optional sound effects, optional 3d icons (using glut), and background and preview pictures. Already installed screensavers can also be used as backgrounds using compositing and transparency.
sdvplayer is a tool to help you improve your vocabulary in a foreign language by watching movies with subtitles in that language. It allows you to look up the meaning of a word displayed in the subtitles just by clicking on it. The meaning will be printed right on the screen and the player will be paused. Playing can be resumed just by pressing the space bar. It can play movies in many of the formats supported by libav*. Subrip (.srt), microDVD, and subviewer subtitle formats are supported. The meaning can be looked up through an external command. The built-in dictionary parser can parse the stardict dictionary format.
