Well, LiveTV is set to:
384x480
RTjpeg
Quality=200
MP3
32000
Quality 7
It's a frontend/backend combination, but I configured it to use it's NIC
address as the master server so that I could set up the frontend on my
desktop PC as well.
But, I just changed my backend IP to be 127.0.0.1 (so localhost only
usage, shouldn't go over the NIC) and tried setting it to MPEG4 with a
bitrate of 1800 and it still froze at about 20 minutes.
The instability after the first freeze appears to be tied to something
in the backend, because I have to restart it before it stops. Although
it doesn't _always_ have to be restarted.
I have also just noticed that the audio gets out of sync by about a half
second somewhere around 10 to 20 seconds before the freeze.
I just realized that I don't have ALSA support compiled into MythTV and
have been using OSS all this time, so I'm in the process of recompiling
right now. To confirm I've done this right, I edit the settings.pro
file to uncomment the two lines regarding ALSA, then run qmake again
then make clean and make... Right?
Thanks,
Tony
