Got a new digital camcorder, pretty cheap - Panasonic PV-GS80. I'm
filming in 16:9 mode, with 16 bit sound.
Capturing with dvgrab, transcoding to DVD-compatible MPEG2. Scripts are
here:
http://florin.myip.org/soft/conv-dvd/
Operating system is Ubuntu 7.04
The problem is, transcode seems to segfault at the end of a DV file. I
used initially transcode-1.0.2 and mjpegtools-1.8.0 provided with
Ubuntu, then I upgraded to transcode-1.0.4 and mjpegtools-1.9.0rc2, but
the segfault still happens.
I can't seem to figure out how to eliminate the segfault. Any help is
appreciated, I will work with anyone willing to fix the problem.
Please note that I wrote the scripts above some years ago and have been
using them with very good results for a long time, but on Fedora Core as
an OS and with an older Sony digital camcorder set to 4:3 image format.
Below are the outputs from two segfaults, one at the default verbosity
level and with default transcode and mjpegtools versions, the other at
-q 2 and with upgraded software:
