Keywords: mp3 regression added
Priority: normalimportant

Is the issue reproducible with ffmpeg or just with kodi? Which commit introduced the regression?
And please confirm that the issue is reproducible with current FFmpeg git head.

comment:3 by FernetMenta, 5 years ago

I tried ffmpeg 3.0 and 3.1. The reason for this regression is exactly the same as mentioned in 5047:
http://git.videolan.org/?p=ffmpeg.git;a=commitdiff;h=6ec688e1bc76dd93151cbca1c340162ae4b10d77

If need_parsing is set to AVSTREAM_PARSE_FULL like prior to this change, it works again.

Regression since ae215e2b42dd172f6bfd9f2dad44c9d5c11884bf
For future tickets: Please always test current FFmpeg git head and provide a command line that allows to reproduce the issue together with the console output.
