I seem to have all of my install mistakes corrected, except for one.
When I play recorded content all is well. But when I play live TV, I get many "prebuffering pause" messages, and an occasional "WriteAudio: buffer underrun". The video stutters during the prebuffering messages.
Hi Michael,
I had a very similar problem which cropped up after switching to ALSA
output. After a long saga of list-trawling, it turned out to be an
error with an uninitialised variable in Myth's ALSA audio module (I so
wish C++ would regard this sort of thing as an error). After grabbing a
patch from CVS and rebuilding, all is fixed.
The patch against 0.17 is attached. Since we have the same frontend hw,
I could look into making the (RPM) binaries available if there's
somewhere to drop them.
Matthew.
Thanks for the patch.
At first, I thought it worked. When I started live tv, 4 pauses and one
underrun where logged, but then it was looking good. That lasted about a
minute, and then it was back to the stuttering.
It's a little confusing, it does not happen recording a program, and it
does not happen when playing a recording, so it's not easy to pin on the
frontend or backend.
That's very odd. My impression is that live TV mode is really the same as watching a recording as it's laid down (with the added feature of the buffer being limited and circular). So the fact that you get the problem only with live TV is unexpected - I was getting it regardless of mode. I also found that FF/RW a few times would re-sync until the next time I hit pause/unpause or a signal glitch threw it off.
May I ask what kind of tuner card you are using?
I'm using a VisionPlus VisionDTV DVB-T PCI card.
Matthew.
