Reported by: | JYA | Owned by: | beirdo |
---|---|---|---|
Priority: | minor | Milestone: | |
Component: | MythTV - General | Version: | Master Head |
Severity: | medium | Keywords: | |
Cc: | Ticket locked: | no |
Description
AAC/LATM playback is broken when the stream change channels configuration (e.g. go from stereo to 5.1)
Samples exhibiting the problem: http://www.mediafire.com/?5zx2x3zv2g6hxys
As soon as the audio configuration change, further AAC/LATM decoding will fail with decoding error messages.
The problem is in FFmpeg and this problem was recently fixed upstream.
These two patches updates myth AAC decoder to a similar version as used in FFmpeg (some changes were excluded)

Some recordings still seem to exhibit the problem, at least on 0.24. Here is a 40M sample that played in mythvideo, goes silent after the first minute or so of playback, and then continues silent, yet the same file with a chunk cut off the front, plays correctly.

My guess was that adding a comment to this closed ticket was the best way to report this. Appologies if that's not the prefered way.

Sorry. False alarm. Ignore Comment 4. It was just confusion due to an 18-day-old release not including 2-month-old changes, plus somehow the corresponding source package including the changes when the binary didn't. Now that I have built from the source package, the problematic recordings work correctly.
Fix AAC/LATM playback for streams with changing config
