[mythtv] Video playback problems

Tue Oct 12 09:33:31 UTC 2004

Hi,

I'm currently trying to identify the source of some video playback problems.
The symptoms are typically perfect playback, followed by pop/squeak activity
during adbreaks, followed by either recovery or hang of mythfrontend. Strangely
the pop/squeak virtually always occurs during adbreaks, most noticeably with
large blocks of white on the screen (a particular ad causes this every single
time). The only way to escape this is to kill the front end process.

I'm using 2xDVB cards, XVMC enabled, ALSA disabled, AMD 2500+ with GeforceMX440
and Gigabyte GA-7VAX Mainboard.

I have a video file which can reproduce this, however I don't know the best
way to trim it to the 1-2 minutes that reproduces the crash. Any suggestions?

A normal level debug log is below.

Thanks,
phil
