[MPlayerOSX-devel] mplayer audio bug in Panther?

[scott r. l. <ol...@lm...>]

hey guys, thanks for such a great product.  i've used mplayer a bit and 
have recommended it to all my friends.

in the past i have had no serious issues with earlier version but 
recently, i've been trying out mplayer version 2.0b8 (not r2) on the 
Mac and i have had a consistent problem that comes up - every time a 
Divx or 3IVx file is played back using the software, the audio comes 
out high pitched and totally garbled in bursts - the video plays back 
fine, however.  

Troubleshooting/Testing:
this behavior occurs starting at version 2.0b5 of the software going 
upwards, and does not affect earlier versions. 

here's what i've done to try to get around the problem - on most older 
Divx files (Ver 3 and ver 4) i am able to play them back perfectly 
using mplayer 2.0b4 down to 1.1.  

oddly enough version 2.0b5 upwards of your program seems to have no 
problems playing back Xvid movie files.  it just seems that the rest of 
the other file types cause garbled audio.

my system:Mac G4 500Mhz (sawtooth) 1Gig RAM, OS 10.3.5  


*****Possible clue - looks like the audio driver was updated as of 
version 2.0b5.   I am currently using a Tascam FW-1884 (like a Digi002) 
Firewire interface with multiple outs.  looks like the audio out wants 
to see 2 channels available only for output and instead it returns 18 
channels (the total number of outputs available on the Firewire unit).  
is there any way to tell it to use 2 channels like the older versions 
of the software do?  Check out this clip from the console dump:

2.0b5
"AO: [macosx] 44100Hz 18ch Floating Point (4 bps)
Building audio filter chain for 44100Hz/2ch/16bit -> 
44100Hz/18ch/32bit...
[channels] The number of output channels must be between 1 and 6. 
Current value is 18
Couldn't find matching filter / ao format!"

2.0b4
"AO: [sdl] 44100Hz 2ch Signed 16-bit (Big-Endian) (2 bps)
Building audio filter chain for 44100Hz/2ch/16bit -> 
44100Hz/2ch/16bit...
Starting playback..."

i guess it would be really nice to have the ability to switch between 
sdl and macosx since sdl plays back the audio fine. 

has anyone else had these garbled audio issues on newer versions of 
mplayer?  whatever help you may be able to give would be greatly 
appreciated.

best
