[MPlayer-users] AV delay required for Win32 codec divxa32.acm

[Neil Sedger]

When playing a certain AVI file MPlayer (20020907) says:


Playing South Park 609 - Free Hat (Sound codec needed).avi
Detected AVI file format!

Playback works 'ok' but it requires a delay of 0.5 seconds - i.e. if I 
add '-delay 0.5' to mplayer's commandline its ok.

Is this because its using the divxa32.acm Win32 DLL?
(this is from the 0.60 codecs archive on the mplayer website).


I haven't got any other AVIs that use this codec... but if its a common 
problem then maybe mplayer should automatically apply the correct A/V delay?

(I can upload the AVI on request)


I've confirmed this on two machines:

a) dual-celeron 500 smp machine running RedHat 7.1 using the matrox mga 
driver on a G400, kernel updated to 2.4.19, SB1024.

b) Athlon 1.4 machine running RedHat 7.3 (kernel 2.4.18, patched for 
nvidia) and X 4.2.0 on a Riva TNT2 Ultra, SBLive.


Both running non-updated OSS (as supplied with RedHat) and separate 
installations of mplayer compiled separately with the win32 codecs and 
libavcodec from CVS in place.
