Using your example decode_audio.c I've compiled it using Visual Studio
2022, version 17.13.3 (debug, x64) and FFmpeg V7.1 to created an EXE file.
Leaving line 132 as original for MP2 files or changing it for MP3 files
(i.e. AV_CODEC_ID_MP3) I've run the EXE on a number of MP2/MP3 files to
create a WAV file, as follows:
decode_audio sample.mp3 sample.wav
I've go several "sample" MP2 and MP3 files that I've downloaded from
Github plus several created using NCH Switch Sound File tool and
decode_audio fails reading the source file with the following error;
[mp3float @ 0000022a16917600] Header missing
Error submitting the packet to the decoder
I'm currently developing an audio stream reader that reads AAC, AIF, AU,
FLAC, M4A, MP4 and WAV files without any problems but fails on MP2 and MP3
files for the same reason cited above for your decode_audio.c example. As
your example files to read MP2 & MP3 files it gives me confidence that I'm
not missing anything in my own development code.
I'm submitting this issue based upon your own example code which ought to
make reproducing the issue somewhat easier.
Thanks for help resolving this problem
