Video Contact Sheet *NIX creates a contact sheet (preview) from videos by taking still captures distributed over the length of the video. The output image contains useful information on the video such as codecs, file size, screen size, frame rate, and length. It requires MPlayer or FFmpeg and ImageMagick. It is confirmed to work on Linux and FreeBSD, and possibly other POSIX/UNIX systems.
Drip is a DVD to divx conversion tool. The application is GNOME based, but the encoding part of it is available as a textmode tool. Using the GUI just makes it all easier, and adds some logic, like automatic filenaming and subpicture detection. Drip does the whole job in 1 go; no user interaction is needed during runtime.
image2mpeg is a tool to convert digital photos (or any other images) into MPEG video streams, with transitions between the images. The photo stream may be accompanied with music (or any other audio stream). The resulting slideshow may be prepared for VCD, SVCD, or DVD playback in stand-alone players, or the MPEG videos may be converted into FLV (Flash Videos). The type of transition can be selected for each image separately from a set of fade, slide, roll, etc.
Camsource is a modularized and multithreaded daemon for grabbing image frames from a video4linux device. It uses a simple yet powerful plugin system, which allows it to use the same grabbed images for multiple purposes at the same time. It features image filter plugins, which can be daisychained in the XML config file to modify the image before passing them to other plugins. Included plugins provide compatibility with camserv (multipart jpeg streams) and webcam_server, a local snapshot file writing module, and an FTP upload module, as well as basic image filtering (resizing, flipping, and rotating).
DeuTex is a wad composer for Doom, Heretic, Hexen and Strife. It can be used to extract the lumps of a wad and save them as individual files. Conversely, it can also build a wad from separate files. When extracting a lump to a file, it does not just copy the raw data, it converts it to an appropriate format (such as PPM for graphics, .au for samples, etc.). When it reads files for inclusion in pwads, it does the necessary reciprocal conversions. In addition, DeuTex has functions such as merging wads, etc.
im2avi is a small program for making AVIs from sequences of images. It makes use of avifile for encoding video streams, so im2avi has access to all the codecs that avifile supports, including DivX ;) or Cinepak. It uses the ImageMagick++ library to load the images, so it supports a wide range of formats.
