0002474: DVD PAL 2 pass render has no audio

Notes
(0007752) j-b-m (administrator) 2012-01-08 16:03	I tried in Ubuntu 10.10 and 11.04 but cannot reproduce your problem. Which FFmpeg packages are you using? Can you paste the output of: ffmpeg -i rendered_file.vob With one of the file rendered without audio?

(0007765) norms2 (reporter) 2012-01-10 14:00	I have been using ffmpeg from git for quite some time without any problems. After using ffmpeg -i xx.vob I noticed there were mismatch? problems so I re-build again yesterday. That problem has now gone away. as requested (and more,sorry):- Selected zone.

(0007766) norms2 (reporter) 2012-01-10 19:07	I removed the audio and it rendered fine. I converted the .mp3 to .wav and it rendered fine, three times! I have had problems with .mp3 in the past and promised myself to convert then to .wav every time, but... I wont forget again. Thanks for your time.

(0007812) pez4brian (developer) 2012-01-22 21:11	The crashes are probably caused by the "insufficient thread locking around avcodec_open/close()". That was recently fixed in the latest development version of MLT. I'm not sure about the missing audio. I haven't seen that myself.
