[FFmpeg-devel] [PATCH] avformat: increase first_frames threshold for mp3, ac3

Attached patch is a quick fix for Ticket4723.
I have a couple of issues with this though:
1. It seems like probe thresholds are essentially tweaked based on
what files are encountered, and that these can't be set precisely
according to a spec.
Is this correct?
2. Comment in the file mentions keeping probing in sync across ac3/mp3.
I kept this in mind for the patch, but don't know the rationale for this.
2. I tested the patch with fate and against the ticket.
However, ideally this should be tested against a variety of mp3/ac3 files,
to make sure the probing still works even with this stricter threshold
Where can I find comprehensive sample files for this purpose,
and more generally audio/video files for ffmpeg development?
