Description
Trying to construct a test file for #2353, I picked a movie recording that had not been transcoded, made a cutlist for it that kept only a few seconds around every transition in and out of commercials, and ran an MPEG2 lossless transcode for it, resulting in a 53 MB file with a lot of aspect ratio changes. Trying to transcode this to an MPEG4 file segfaults.
The transcoding profile is no resize, MPEG4 codec, 2100 kbps, maxq=2, minq=25, qdiff=3, HQ, 4MV, i-DCT and i-ME all disabled, audio MP3 at 44100, q=6, vol=90.
Even with -v all, the mythtranscode log file doesn't show anything particularly informative before the segfault. I've put the recording available at http://htpc.home.fishpool.org/tmp/transcode-segfaults.mpg (53MB)
I have a new test case that kills mythtranscode directly from DVB->MPEG4 transcode without applying cutlists etc. The sample file (7 minutes, 170 MB, containing mostly commercials) can be downloaded from http://htpc.home.fishpool.org/tmp/1006_20060925183000.mpg. Will attach mythtranscode output and crash backtrace... Please inform if there's something else that is needed to track this down - I'd be happy to debug or try patches.
