[MPlayer-advusers] FAAD problem on AMD64: no sound

[Daniel Hottinger]

Hi,

Short version:

Distribution: Debian/SID, pure64 port for amd64
MPlayer-CVS : 2005-03-25, ~10:00am
Problem     : no sound when internal FAAD2 is used
Sample data : ftp://mplayerhq.hu/MPlayer/incoming/zx.eva.renewal.01.divx511_first_5mb_amd64.mkv
MPlayer -v  : zx.eva.renewal.01.divx511_first_5mb_amd64.txt
Bugzilla    : nothing found

Long version:

There seems to be a problem with the internal libfaad on amd64.
The sample file has two audio streams: AAC and Ogg/Vorbis. The
playback of the 6-channel AAC stream [faad] is completely silent
(but the volume is normal at 50%) while the playback of the
2-channel Ogg/Vorbis stream [libvorbis] works. Surround ist not
the problem since wav-files with 6 channels work. Also, on my
laptop (Pentium III, x86) faad works nicely with the same file
and the /same/ relevant output:

---------------------------
Opening audio decoder: [faad] AAC (MPEG2/4 Advanced Audio Coding)
dec_audio: Allocating 4608 bytes for input buffer.
dec_audio: Allocating 49152 + 65536 = 114688 bytes for output buffer.
FAAD: Decoder init done (0Bytes)!
FAAD: Negotiated samplerate: 44100Hz  channels: 6
FAAD: compressed input bitrate missing, assuming 128kbit/s!
AUDIO: 44100 Hz, 6 ch, s16le, 128.0 kbit/3.02% (ratio: 16000->529200)
Selected audio codec: [faad] afm:faad (FAAD AAC (MPEG2/MPEG4 Audio) decoder)
---------------------------

Interesting is that the Debian vlc (0.8.1) also uses FAAD and can
play video and the AAC sound. I've tried all 26 files of
Evangelion and also some others with 2-channel AAC audio. Same
Result.

I am on the list and would like to help to track this bug down.
