I was thinking in terms of recording with DV OR zoran and playing back
*WHILE* recording.
Requirements (beyond what you specified):
I For Zoran (rec) + Zoran for (play)
- snd card needs to be able to sample and play at the same time
(impossible?)
- lavplay -p -C needs to be able to play at a proper framerate without
the index at the end of avi
- speecified temp file of avi index in separate file until lavrec ends
(then simply append).
- increased IPC for lavrec/lavplay for simultaneous rec/play
- to implement: inform any lavplay process when there is a
a) new frame or
b) new file (2GB max)
c) end of recording
II For DV (rec) + Zoran playback
- realtime dv to lav converter with same IPC mechanism above
- snd card only needs playout capability
Thoughts?
