Hi,
i made an audio decoder based on libav. It works well.
I've come accross two mp3 files that can't be decoded by my decoder. It
fails on avformat_find_stream_info with the message "operation not
permitted"
Avplay can't read the files properly:
* for the first one, it ends immediately with :
[mpeg @ 0x7fef0c005c60] Could not find codec parameters (Video:
[0][0][0][0] / 0x0000)
[NULL @ 0x7fef0c004fc0] start time is not set in estimate_timings_from_pts
test.mp3: could not find codec parameters
* for the second one, it reads the file, however, no sound. The header
of the file seems invalid.
mplayer, vlc are able to play the files.
The files seems to be invalid, so i've not yet submited a bug report.
The first file you got me seems to have a very large cover image, by
default we have 5M as probe limit, the cover image is about as large,
adding -probesize 10M solve the problem.
The other file is even more interesting since it is on the bordeline
between being probed as mp3 or as mpegps.
After looking at it a little I came with a patch now on review, thanks a
lot for the reporting.
