I have spent the last few weeks learning about libav to try to decode mp3 files
so I can create videos with the audio from the mp3 files.
I have built ffmpeg with libmp3lame (latest version) included and I get no
errors when opening the mp3 decoder.
I have tried to decode the mp3 file in every many different ways I can find.
avcodec_decode_audio4 and avcodec_decode_audio3 both return header missing
error.
I can get the mp3 packet calling fread or av_read_packet but av_read_frame just
crashes. I have ensured that the stream index is correct before trying to
decode the packet.
I have tried many different mp3 files. I am using the latest ffmpeg snapshot.
When calling avformat_find_stream_info with my mp3 format context I get a seg
fault crash. This crash doesn't happen for any other file type, just mp3 files.
Can anybody please give me sufficient knowledge to move on from this as I
really want to work with mp3 files with libav.
Why do I get header missing when decoding mp3 only and why does
avformat_find_stream_info crash only for mp3 files?
Let me know if any more information is required.
Thanks
Bradley
