OMX_AllocateBuffer fails for audio decoder component ...
https://forums.raspberrypi.com/viewtopic.php?t=28313
Browsed to the latest omxplayer code in XBMC and it always is using OMX_AUDIO_CodingPCM as audio encoding instead of also allowing OMX_AUDIO_CodingDDP for AC3. I think the audio_decoder is still only allowing audio passthrough or PCM audio. And XBMC is using ffmpeg to convert audio stream to PCM or uses passthrough.
