[Libav-user] av_probe_input_buffer wont recognize AAC

[Christoph Winter]

Hey Andrey,
thanks for your reply.

1) ffprobe recognizes the correct sample_rate (av_open_input_file, too)
4) I tried that before but it did not work neither

2-3) I uploaded a small sample including the mp4 file: 
www.asamnet.de/~winterch/libav_stream.tar.gz
It's a small Qt project so you need qmake and maybe also change the LIB 
paths in the .pro file to compile. You should see that in the first 
av_dump_format the sample_rate in the aac audio stream is missing.

Thanks in advance,
Christoph
