[xine-user] DXR3 sync report

[Michael R. <ama...@fr...>]

Hello all (especially Harm),

i've just compiled the latest CVS of xine and want to share my 
experiences with the DXR3 syncing quality. I am using DXR3 digital 
passthrough, so some of the problems might be related to this, although 
I recognized them too with passthrough disabled.

One thing first, the syncing offset between audio and video now no 
longer varies over time. With the new framewise syncing it is 
quite stable as soon as the frame skip value reaches zero. But there 
are two remaining issues:

1. The offset is not zero! Audio is constantly ahead of video, quite 
few, but noticeable. I have "fixed" this for myself by using OSS 
softsync with an audio.oss_latency of -150.

2. The frame skipping value does not always reach zero. For some 
streams, it starts with higher values and doesn't decrease, sometimes 
it even starts increasing within the stream. Usually seeking in the 
stream (e.g. pressing cursor left) fixes this.
