Wrong PTS values for aac

[Nikola Vranic]

Summary of the bug:
I am using ffmpeg library inside my project to extract packets from media stream. I was able to extract all stream so for, except this one. I don't know why but ffmpeg returns me wrong PTS value for audio. Hole stream duration is ~5s, but audio PTS goes to ~334s. I think that this I is bug inside ffmpeg library. I also try with latest master version from git ​git://git.videolan.org/ffmpeg.git and I got same think. I successfully fix this by changing avidec.c.

ffmpeg version 0.10.2 and 0.11.1
built on ubuntu 10.4

Change is on line 121.

Do you think this is a regression?

Since this is probably reproducible with ffplay, please provide complete, uncut console output of ffplay LIBX264_LIBFAAC.avi (it is significantly easier to work on bugs that are reported against ffmpeg or ffplay instead of your local application.

If you have a fix, please send a patch created with git format-patch to ffmpeg-devel.

[Nikola Vranic]

This is a output from ffplay. When you run ffplay command you can see that current stream position are changing mush faster than it should. This is because he read bad audio PTS values. I am just send path to ffmpeg-devel.

Nikola
