First problem is that TrueHD frames arrive in the decoder with only a few timestamped and most having AV_NOPTS_VALUE. ffplay.c solves this by calculating the correct pts for those unmarked frames.

After that it may be the small frame size (40 samples) exposing inefficiencies; playback of Wayne's World sort of works but it's slow.

Nothing obvious in callgrind; coalescing 40 sample blocks into bigger blocks before resampling doesn't help.
