We're running into a strange issue with an mp3 where it throws a "header
missing" error if played straight through, but plays through fine w/ a seek
to 1. E.g., using D_0.mp3 from:
$ ffplay -autoexit D_0.mp3
[mp3 @ 0x25ee0c0] Header missing 0KB vq= 0KB sq= 0B f=0/0
1336434931.49 A-V: 0.000 fd= 0 aq= 0KB vq= 0KB sq= 0B f=0/0
Whereas with a -ss 1 no "Header missing" error occurs:
$ ffplay -autoexit -ss 1 D_0.mp3
15.52 A-V: 0.000 fd= 0 aq= 0KB vq= 0KB sq= 0B f=0/0
Running a read_frame/avcodec_decode_audio loop shows avcodec_decode_audio
returning -1 on the very last packet (ignore the return code and read_frame
return EOF next). Additionally, using a backwards seek to 0 shows error,
however a forward seek to 0 does not.
As far as I can tell it's been an "issue" since at least July 2011. Haven't
found a passing build yet for bisect. Full logs at
Thanks in advance for any assistance.
