ucanvcam is a cross-platform framework for building virtual cameras. Virtual cameras offer the same interface as regular cameras to client applications (such as Skype), but provide user-generated or user-modified imagery rather than imagery directly from a camera. While ucanvcam comes with a set of special effects, the main intent is to make building virtual cameras easier for people without OS-specific knowledge, so they can focus purely on image processing.
MPEG Audio/Video Player is a simple MPEG and AC3 player for Linux, BSD, and Windows systems. It plays MPEG transport, program, and elementary stream files. It also has basic DVD support (using libdvdnav on Linux/BSD systems only). It features newly developed integer decoders for MPEG 1&2 video, MPEG layer 2 audio, and AC3 audio. It includes a partially working WMV/VC1 decoder capable of displaying I and P frames.
