Hello Geoffrey,
GH> How recent is your mythtranscode?
I checked out a fresh copy of myth before running this bt.
GH> The segfault happens inside the encoder, which likely means that some
GH> variable wasn't initialized. I fixed just such a problem last week.
GH> There is nothing obviously wrong in the myth portions of that backtrace
GH> (I'm not about to dive down into the libavcodec stuff right now).
GH> Also, does it happen when not using the '-l' switch? This shouldn't make
GH> any difference as far as encoding goes, but if it does, it probably has
GH> something to do with the frame-numbers getting hosed.
I'll try without -l right away and tell you what happens.
GH> Is there any chance of you being able to deliver the mpg to me? It would
GH> make it a lot easier to debug.
Sure, it's about 2.5 gb and I'm on 512kbit DSL, will take a while, but that's ok
for me.
GH> If not, the answers to these questions
GH> would be useful, as well as your encoding settings for the Transcoding
GH> profiles:
GH> select * from codecparams;
GH> select * from recordingprofiles;
Comming right up:
mysql> select * from codecparams;
