I can't run mythtranscode on DVB-T files that don't have a video stream since
using myth 0.21. Nuvexport does this:
Now encoding: The Chris Moyles Show: Untitled
Encode started: Sun Jun 15 13:54:26 2008
Waiting for mythtranscode to set up the fifos.
sh: line 1: 2039 Segmentation
fault /usr/bin/nice -n19 /usr/bin/mythtranscode --showprogress -p 27 -c
2700 -s 2008-04-28-08-45-00 -f "/tmp/fifodir_1961/" --honorcutlist --fifosync
2>&1
Waiting for mythtranscode to set up the fifos.
Running the mythtranscode command in more detail and verbose options on gives
the data at the bottom of the mail. I think the problem is I don't have the
right playback profile for playing stuff without video, but I don't know what
options I need to set as defining a profile for 0x0 pixel video doesn't get
used.
Also, mythtranscode probably shouldn't segfault. Backtrace:
#0 0x0000000000029241 in ?? ()
#1 0x000000000042468b in ~Transcode (this=0x7a2d20) at transcode.cpp:252
#2 0x0000000000417ffe in main (argc=9, argv=0x7fff09f58b08) at main.cpp:643
I haven't worked out how to explain to gdb that I have the svn source, as
source directives only seem to work for some files (not counting qt3).
