Description (last modified by )
Summary of the bug:
I used ffmpeg-107064-g7adeeff91f UTC compile date: 2022-04-05 to reproduce this bug.
How to reproduce:
./ffplay -seek_interval 20 skips_after_seek.mp3 ffplay version: ffplay-106494-g1291568c98 built on 2022-04-05
Start playing and press right arrow once to seek 20 seconds. At ~30s, the playback time and audio will jump to ~40s, In my application, I noticed the packet->pts jumps correspondingly after call to av_read_frame().
This only happens with some files, I have only one example from a user so far, but my application receives a fair amount of complaints about this. It didn't happen with older versions of ffmpeg, probably < 4.0.
Here is a link to the sample file used to reproduce: https://drive.google.com/file/d/1UMSQSxdgat-hibQcctJTVWb6RX9g0QG6/view?usp=sharing

Replying to Balling:

I put a link to a test file that you can reproduce it at: https://drive.google.com/file/d/1UMSQSxdgat-hibQcctJTVWb6RX9g0QG6/view?usp=sharing I'm aware it's AAC with an mp3 extension, that's how it came to me
I can't cut the file size down because it makes the problem go away and the ftp seems to be down so idk
