Description Dominik 'Rathann' Mierzejewski 2006-04-12 13:18:45 UTC

Description of problem:
There's a bug in libebml-0.7.6 with float variables aliasing which breaks AAC
muxing when compiled with gcc-4.1. It has been fixed in 0.7.7 (I've tested it
myself), so please update and rebuild.

Version-Release number of selected component (if applicable):
libebml-0.7.6-2.fc5

How reproducible:
Always

Steps to Reproduce:
1. Take any mkv/mp4/mov file containing AAC audio
2. Remux it into a new mkv file using mkvmerge/mmg
  
Actual results:
Playing the new file with MPlayer makes libfaad spit a lot of:
FAAD: Failed to decode frame: Maximum number of scalefactor bands exceeded
and audio playback fails.

Expected results:
AAC audio should play without errors.

0.7.7 commited.

Comment 2 Hans de Goede 2006-07-23 09:09:17 UTC

I'm taking over as maintainer from Anvil, since Anvil has other priorities.
0.7.7-1 has been build and published a long time ago, closing.
