Infrequently damaged/corrupted nuv files
damaged/corrupt nuv file???
I have been using mythtv with great success for several months now and
it has worked almost flawlessly except for one small problem that comes
and goes at random. Every now and then one of the recordings seems to
be damaged, or at least somehow encoded wrong.
The entire time is recorded but when I attempt to play back the material
it jerks through the file with no audio. Sometimes the audio comes back
for part of the recording. When I enable the "jitter control" feature,
it plays better, but the audio is out of sync and it still jerks/pauses
every few seconds. What puzzles me is the infrequently of this event,
it was a problem several months ago and now has reappeared today 2/25/03
without any pattern to time/day/channel/show that would explain it. The
machine is a 2100XP with 768ram so speed and the hard drive should not
be an issue.
When I first started using MythTv I used the nuppel codec on an old
Athlon 700mhz, but now I use mpeg4 with cvs current as of 2/24/03
(2000kbs) hardware and codec would not seem to be the problme. It seems
to me that the audio track may somehow be the culprit, but since all the
other recording are fine I don't know how to investigate this further.
Neither the backend nor the frontend crash when recording or playing
back the clips so running it in the debugger would not seem to be of any
If anyone has an ideas please let me know. I am more than happy to
provide information or implement some simple debugging, but I don't know
where to start looking for this problem. I seem to remember a while ago
that their was a problem with the index being generated under some
circumstances, but I was sure that was fixed in cvs long ago.
Thank you Isaac and everyone else for making Mythtv the most amazing
application I have ever scene! Finding open source applications with
great code, fast development, high developer interaction, and excellent
documentation (Used the first release with perfect sucess!) are hard to
Thanks for your help,
