Replying to [comment:49 Tyson Harding <tharding at cs.utah.edu>]:
> I couldn't get this to play DVDs with "Extra Audio Buffering" enabled.
Six channel audio would not work, the frontend would get stuck in a loop
with a black screen. The logs showed
> {{{

> I was able to fix the problem by either turning off "Extra Audio
Buffering", or changing the AVCODEC_MAX_AUDIO_FRAME_SIZE value from 192000
to 384000, so now avcodec.h has
> {{{
> #define AVCODEC_MAX_AUDIO_FRAME_SIZE 384000 // 2 second of 48khz 32bit
audio
> }}}
I'm now experiencing this same issue with latest SVN playing some/most
DVDs. None of the suggested fixes work for me - Extra Audio buffering is
off and FRAME_SIZE increased to 384000.
I see this (I believe "audio stream changed" is the cause):
{{{
[ac3 @ 0xb7392688]buffer 192000 too small
audio stream changed
NVP: Disabling Audio, params(0,-1,48000)
[ac3 @ 0xb7392688]buffer 192000 too small
[ac3 @ 0xb7392688]buffer 192000 too small
[ac3 @ 0xb7392688]buffer 192000 too small
...
}}}
