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.
