Stuttery playback for some AVI file

Reported by: JYA Owned by:

Component: MythTV - General Version: 0.26-fixes
Severity: medium Keywords:

Description (last modified by JYA)

Since the upgrade of 0.26, some of my AVI rip stop playing.

The reasons is a change in ffmpeg that detects the video as being non-interleaved. This in itself isn't a problem.

Myth will play the file just fine if the file is local, but over a 100Mbit/s (or wireless link) network link via Storage Group, it will stutter very quickly

Running mythfrontend with -n network --loglevel debug shows that the frontend starts to pull from the backend read of 1MB in size which takes too long and cause the playback thread to starve for data.

What need to be investigated is why the ringbuffer starts to pull so much data as opposed to when the file is interleaved. When the file is detected as interleaved, block size stay at 32kB.

Limiting the size of the block size to not exceed 128kB does help a little bit, but doesn't fully fix the issue.

Playing the file detected as non-interleaved show a great amount of seek before reading, which the ringbuffer code doesn't handle well at all as it keeps pre-fetching data

Note that playing the same file over http, works just as well, you can seek just the same...

got fixed a while ago (though not a very nice patch)
