[Ffmpeg-devel] weird sound with mp3 decoder, bits left

[Baptiste Coudurier]

Hi

Something weird with mp3_bits_left.avi on mplayerhq

Sound is very garbled:
ffplay mp3_bits_left.avi


Input #0, avi, from 'mp3_bits_left.avi':
  Duration: 00:02:57.6, start: 0.000000, bitrate: 46 kb/s
  Stream #0.0: Video: mpeg4, yuv420p, 720x576, 25.00 fps(r)
  Stream #0.1: Audio: mp3, 32000 Hz, stereo, 192 kb/s

bits_left=34
bits_left=76
bits_left=190
bits_left=21
bits_left=203

...

mplayer + self + mp3lib, it sounds fine.
mplayer + lavf + mp3lib, it sounds fine
mplayer + lavf + ffmpeg, same as ffplay.
mplayer + self + ffmpeg:

Opening audio decoder: [ffmpeg] FFmpeg/libavcodec audio decoders
[mp3 @ 0x88b0138]incorrect frame size
invalid new backstep 11159
[mp3 @ 0x88b0138]Header missing skipping one byte.
[mp3 @ 0x88b0138]Header missing skipping one byte.
[mp3 @ 0x88b0138]Header missing skipping one byte.

And sounds hear even more garbled.
