Can you provide a small sample that reproduces the problem?

Either the file is invalid or FFmpeg doesn't support the way mp3 is stored in it. Try in ffmpeg and report a bug to them if it happens there too.

[Deleted User 11865]

FFmpeg can't open the file, but ironically libav can.

[JohnAStebbins]

The file has a DecoderConfigDescriptor with a length field of 0. The ISO/IEC 14496-1 spec doesn't indicate that this is an error. It only says that length is the size of the remaining descriptor after the length field. So this is an ffmpeg bug IMO. The function ff_mp4_read_dec_config_descr returns an error when this length is 0. If I comment out this error return, the file plays.

[Deleted User 11865]

I reported the b ug to FFmpeg, they seem to be working on it.

I have the same problem. Although I though handbrake could slice / edit straight audio files... I dragged a simple mp3 file into the program and I get the same error, no valid titles or source found. I take it handbrake cant handle mp3 files?? Why? It can handle video formats which include audio formats, but not just simple audio alone? Handbrake should add that feature its a little absurd its not there. I just want to trim some audio clips. Sigh.... nothing ever works

Handbrake is a VIDEO transcoder. It isn't an editor (video or audio), and it isn't intended for audio-only files.

Have you looked at Audacity?
