The VideoLAN Forums

I'm on Windows 7 32bit and I have a Radeon HD 3650.
in vlc-1.1.7 the option for "use GPU acceleration" is checked
and directx_Jun2010 is installed.
I tried three different drivers:
8.56.1.16 2009-04-25
8.771.0.0 2010-08-25
8.821.0.0 2011-01-26
None of them gives any H264 acceleration.

DXVA checker says for all three:
ModeMPEG2_IDCT DXVA2 NV12 720x480 / 1280x720 / 1920x1080
ModeMPEG2_A DXVA1 NV12 720x480 / 1280x720 / 1920x1080
ModeMPEG2_C DXVA1 NV12 720x480 / 1280x720 / 1920x1080
ModeH264_VLD_NoFGT DXVA2 NV12 720x480 / 1280x720 / 1920x1080
ModeVC1_VLD DXVA2 NV12 720x480 / 1280x720 / 1920x1080
5B23D46D-FA5F-4FDC-B78A-7EB2787942EC DXVA2 NV12 720x480 / 1280x720 / 1920x1080

I have another PC with almost the same setup, except that it has a Radeon HD 3450.
Here the GPU acceleration works perfect.

So what could be the reason it's not working with the Radeon HD 3650 ?

ModeH264_VLD_NoFGT DXVA2 NV12 720x480 / 1280x720 / 1920x1080

Should be enough.

Please provide logs.

I tried to enable logging in the preferences: Advanced -> Logging
Whatever filename and verbosity I specified, there is no logfile.
Did I miss something ?

Yes, Tools->Messages, verbosity to 2.

here is the log.
By the way: without GPU acceleration the video is choppy.
Setting "skip-filter for H264" to all improves a lot, but it's not perfect.
With GPU acceleration there is only a still picture visible, probably
the first frame in the movie.

According to your logs, the acceleration takes place, but this card is too slow to send the data back to VLC's core...

Hmmm, sending back to the core ? For post-proccessing ?
Well the PC is an older shuttle with an AGP graphics card.
It was supposed to become recycled as an HTPC. I dont' t
know the bandwidth of AGP but for for sure, it's far less
than with PCIe.

Is it possible with an reasonable amount of effort to
implement an option to bypass post-processing in order
to send the data directly to the screen ?

Is this kind of architecture specific to all media-players ?
In other words, would I have more success when trying
another media-player, eg MPC Home Cinema ?

Yes, the AGP is the issue.

The right architecture isn't done now in VLC. Someone might do it...

MPC-HC should be bettter, indeed.

confirmed, with MPC-HC is works perfect.
