Audio speed from mythtranscode in fifo mode is messed up

[xris]

Sometime between [11202] and [11313] (maybe [11294]?), anything I encode with nuvexport (it uses mythtranscode's fifo output method) has messed up (very fast) audio. This happens with all of the export types (ffmpeg and transcode), and it has the effect of the memory buffers growing huge from mythtranscode buffering video frames into RAM while sending out audio data faster than it should (it's almost like it's just ignoring some of the audio frames).

Anyway, nasty bug, and it prevents nuvexport from working. I'm rebuilding with [11294] removed and will update when I can test.

Nope, looks like the culprit is something else.

I just double-checked and reverted to [11202] and indeed the audio now works fine again.

I wonder if this is related to the problem I reported in #2501? It also occured in transcoding, though that was internal MPEG2->MPEG4, and only occur on recordings from a specific channel. The timeframe for the changes you provide sounds about right too.

up through [11294] and still no trouble.

And broken in [11313]

Ok, problem found. Must have been something wacky in ffmpeg's code. Keeping the rest up to date and reverting only the changes in [11307] fixes the problem.

looks to be fixed in [11379]
