compiles with avifile (current cvs), gcc-3.2
run with kernel 2.4.18, normal bttv drivers
I made only a 30sec test with xvid, but that worked fine.

I had a short look at vcr source, it's basically like avirec, just a bit
different?
The source looks very much like samples/qtvidcap/*
I had especially a look at your capproc.cc, cause I'd liked to know if you've
got a working A/V sync or not (because A/V sync in
samples/qtvidcap/capproc.cpp was disabled/commented)
A/V sync for avirec/avicap works like this:
capproc.cpp::audcap()
double timestamp_shift=(audioblock+m_pDsp->getSize())/abps;
if(m_pProgress){
m_pProgress->setTimestampShift(timestamp_shift);
}
ch.size = m_pDsp->read(ch.data, audioblock);
int64_t ct = longcount();
//double freq=550000.;
//printf("ACT %d %d %f %f\n", audioblock, m_pDsp->getSize(), abps,
timestamp_shift);
#if 1
if(starttime)
ch.timestamp=double(ct-starttime)/(freq*1000.)-timestamp_shift;
else
ch.timestamp=0;
#else
#warning "compiling without synchfix!"
ch.timestamp = bufsize / abps;
#endif
while you in capproc.cc have:
if(a.starttime)
ch.timestamp=double(ct-a.starttime)/(freq*1000.);
// ch.timestamp=to_float(ct, a.starttime);
else
ch.timestamp=-1;
You're not calculating a timestamp-shift...?
But you're doing also some things different there, so I don't know exactly.
I just wanted to say: if vcr should have problems recording with perfect A/V
sync for a long time (some hours), then you should look at that part of our
source - or just ask me ;-)
And, by the way:
another one who probably uses cron or at to 'record on timer' ;-)
Well, at least my timertable GUI works fine for me ;-))
