A Linux Video Toolbox

1. Introduction
2. Implementation
3. Video Devices

We are planning to develop a video-toolbox containing:

• rvrecord: record video using V4L2
• rvplay: the player, maybe using PerlTK, or raw X11; let's see
• rvconv: convert single frames (PPM, JPEG etc) and WAV, RSS sound-stream into RVS-format.
• rvcut: cut video stream (simple)
• rvpaste: paste video section (simple)
• rvfade: fade two streams into a third stream (easy to implement, unless different fps, or audio-codecs)
• rvtoavi: convert RVS-format into AVI format (could be cumbersome, unless simple codec is used)
• avitorv: convert AVI to RVS-format (probably hacking XAnim)
• rvtompeg: convert RVS-format to MPEG (tools exist to handle PPM)
• mpegtorv: mpeg to RVS-format (source should be existant)

Raw Video Studio 2. Implementation

In the moment these two formats (plus our own) are considered:

OpenStream by Indrema.Com New open source architecture for full-featured video and multimedia on Linux

QuickTime for Linux Library to read/write QT movies

RVS Specification Proposal Our own video-format and codecs (still under development)

Some of the apps are already coded without actual video-codec details. We experimented with an custom video-format already, but for sake for greater acceptance prefere to use one of the above listed resources about the actual codec details.

Raw Video Studio 3. Video Devices

In the moment drivers for Bt848, QuickCam and few other cards are under development. Check Video4Linux Resources for updates.
