[MPlayer-users] m2ts (blu-ray rip) audio/video sync issue: performance advice?

[Dâniel Fraga]

	I have a blu-ray rip here and if I use VDPAU acceleration
I have audio/video sync issues. My hardware:

Athlon X2 5600+ (2,8GHz)
2GB DDR2 800MHz
Geforce 9600GT
Linux 2.6.31
Latest nvidia driver: 190.42
Latest SVN MPlayer: r29832

~/.mplayer/config:
[default]
stop-xscreensaver=1
ao=alsa:device=default
vo=vdpau
mouse-movements=yes
fstype=layer,stays_on_top,fullscreen,above

	***

	So, if I use:

mplayer -vc ffh264vdpau -aid 4352 -fs -af pan=2:1:0:0:1:1:0:0:1:1:1:1:1
-channels 6 -lavdopts threads=2:skiploopfilter=all -subdelay -12 -sub
legenda.srt 00001.m2ts

	I have audio/video sync issues (video delayed for instance)

	If I don't use the VDPAU acceleration (removing the -vc
option), I don't have audio/video sync issues (although the CPU will
be used a lot).

	The -lavdopts are absolutely necessary, otherwise I cannot play
this m2ts file in my machine.

	So, do you have some suggestions, so I can use the 9600GT
acceleration (and give the CPU some rest) without having the sync
problem?

	Thanks.

	PS: after some testing, I discovered that removing the subtitle
options (-subdelay -12 -sub legenda.srt) helps (no video delay), so
probably adding a subtitle will add a lot of overhead on video
processing, right? But I absolutely need the subtitle, so is there a
option to improve the performance when using the subtitle without
having to give up on the VDPAU acceleration?

	PS2: here is the mplayer output, if for some reason it's
important:
