XVideo XvMC VLD broken

Hi,

The current MythTv CVS version (2004-04-25) of the Xv/XvMC merge appears
to be broken on a Via M10K box using XvMC VLD acceleration.

Problems are:
1. If DVB-T cards are set to TS mode the system will show TV
on startup, but will fail on channel change.
Before changing channel I get the following Errors repeated:

2005-04-25 06:38:19.007 AddInheritence(A ) Error, future=frame
2005-04-25 06:38:19.127 AddInheritence( B ) Error, future=frame
2005-04-25 06:38:19.247 AddInheritence( C ) Error, future=frame
2005-04-25 06:38:19.487 AddInheritence( D ) Error, future=frame
2005-04-25 06:38:19.607 AddInheritence( E ) Error, future=frame
2005-04-25 06:38:19.727 AddInheritence( F ) Error, future=frame

After changing the channel I get:

2005-04-25 06:38:28.247 AddInheritence( E ) Error, future=frame
adding pes stream at pid 0xb03 with type 2
adding pes stream at pid 0xb04 with type 4

I suspect this could be caused by not calling the XvMCSyncSurface().
This call releases the HWMPEG controller for other processes, and
I suspect a lock is not being released when it is not called.

2. If DVB-T cards are set to PS mode the system will show TV
on startup, but will fail on channel change.
Before changing channel I get the same errors as for TS mode:
After changeing I get no picture/sound with the following errors:

2005-04-25 06:48:23.866 Prebuffer wait timed out 10 times.
2005-04-25 06:48:24.482 AddInheritence(A ) Error, future=frame

2005-04-25 06:48:31.113 Timed out waiting for free video buffers.
2005-04-25 06:48:33.312 Timed out waiting for free video buffers.
2005-04-25 06:48:35.512 Timed out waiting for free video buffers.
2005-04-25 06:48:37.711 Timed out waiting for free video buffers.
2005-04-25 06:48:39.911 Timed out waiting for free video buffers.
2005-04-25 06:48:42.111 Timed out waiting for free video buffers.

I suspect this is a DVB issue.

3. The sound/video stutter badly on channes with multile audio
channels. This used to be cleared by setting the DVB-T
option "HW Encoder", but this no longer seems to
work .... (Probably a DVB/AVCodec issue).
