Someone else asked this a few months ago, but nobody answered. It popped up
for me when I wanted to edit the commercials out of this week's Battlestar
Galactica for archiving. The source file was an MPEG-2 transport stream
recorded from an SA3250HD. It's 528x480, with an average video bitrate of
about 3.25 Mbps and 2-channel AC3 audio at 256 kbps.
avidemux2 had no problem loading and cutting this file, so I now have an edited
MPEG-2 program stream. (This stream will then get fed to a script that will
transcode the video to H.264 and the audio to AAC, with the result dumped into
an MPEG-4 container, but that's neither here nor there.)
After having done the edit with avidemux2, I saw that there was a temporary
file left behind by the MythTV transcoder. It was about the same size as the
avidemux2 output. When I played it, it appeared to have converted the whole
file properly, so the only thing that would've been left would be to copy the
edited file over the original and rebuild the seektable. Why, then, is it not
doing that for some files?
I'm running build 12376, as Gentoo builds it. I've only had this version
installed for a few days, but I've occasionally seen the same error with
earlier versions. Most files transcode OK, but "status 235" isn't particularly
informative as to what causes some files to not transcode.
(I had some minor database corruption, most likely as a result of a lockup
earlier this week. I fixed it with mysqlrepair, but that didn't get the
