Increasing the bttv buffer size makes a large difference in length of
time audio will play back successfully using the BT878 (in the Hauppauge
WinTV PVR-350). I am using an Audigy 2 sound card. The CPU is an Intel
3Ghz with only 512K RAM.
sudo gedit /etc/modprobe.conf and change the value of gbuffers to 512
mplayer /dev/video0
Lengths of time audio and video interleave properly until "Cannot sync
MAD frame" error occurs. Both video and audio stop; then the video
restarts but the audio does not:
gbuffers=16 (29 seconds)
gbuffers=32 (1 minute 10 seconds)
gbuffers=128 (5 minutes 11 seconds)
gbuffers=256 (18 minutes 33 seconds)
SO I kept increasing gbuffers and rebooting the machine. Didn't work.
Even backing the values down again ... it now hangs after 5 seconds to a
minute. Heat?
The single line in /etc/modprobe.conf now reads "options bttv radio=1
tuner=28 card=72 gbuffers=128 i2c_delay=128"
