Bummer - Linux Media Labs LLC would break even in 1998 financially . Tcl script added. We're putting additional JPEG markers into the video stream to indicate the size of the frame to follow. That does not violate the JPEG standard and allows handle the resulting files with any image viewer program. Streaming capture and playback works.
Main bottleneck is the disk drive performance.
Subjectively such video looks very good, at least as good as DVD does. Applying Unix paradigm works out very well so far. Then, even without any video manipulation tools I was able to use jpgdump.p script to identify frames in the resulting frame and used dd to cut and paste, so elementary video editing is possible - like cutting and splicing. It seems like it would be possible to make Tk based GUI tools for simple video editing quite easily. Should be no more then 1-5 Kb of sound data per frame even without any compression.
