Hello there. Using vista and when i activate EVR no video plays. I have no idea what i am doing wrong

Any help would be amazing!!

comments and suggestions are always welcome.

First off, nice work.

Secondly, i noticed that the frame grabbing functionality that i use for capturing video frames for the autocropper doesnt work when EVR playback is used.

What i do is take the surface handed to PresentSurface in PlaneScene.cs and hand that over to the OnFrame method in FrameGrabber.cs. In there i call a helper method "VideoSurfaceToRGBSurface" in DXUtil.dll to convert the surface to an RGB surface from which a bitmap can be obtained.

The source for that method is:

VideoSurfaceToRGBSurface(IDirect3DSurface9* source, IDirect3DSurface9* dest)
{
IDirect3DDevice9* device = NULL;
HRESULT hr = source->GetDevice(&device);
if(!FAILED(hr)){
hr = device->StretchRect(source,NULL,dest,NULL,D3DTEXF_NONE);
}
return hr;
}

When in EVR mode this call fails returning D3DERR_INVALIDCALL. Is there something special about the surface that gets handed to PresentSurface when using EVR compared to VMR9?

Hi.

I use the same function ziphnor mentioned in my ViewModeSwitcher plugin. Like the autocropper this plugin analyses frames grabbed from the stream. Right now it does not work under EVR, which means all the users of my plugin have no chance to enable EVR without loosing a lot of functionality.

there is a known (and rather hard to find) bug atm, which will cause videos not to start every few times. (most of the time, i can only play a video 2 or 3 times before i have to kill MP). unfortunately i haven't been able to put my finger on it yet, so this is top priority at the moment.

if you could provide mediaportal.log and vmr9.log, and if possible a download link to the video you are trying to play, this could be helpful.


as for the video capturing problems: it is noted, but i haven't had any time yet to take a look at it. and as i'm away for the rest of the week, i will think about it next week.

we had this issue before with vmr9
Not sure if this is the same or not, but for vmr9 the problem was
that not all interfaces / comobjects where released properly
after the video was stopped

the interesting thing about this is, that it only happens when using the cyberlink codec (my test file is a h.264 .mov apple-trailer from marie antoinette). when i play a divx file, i can start/stop the player as many times as i want without any trouble.

i think i need to get more test-files which use the cyberlink codec, to see if it's a problem with the container format or something. it is really getting frustrating. good thing that i am not able to become more frustrated until monday, when i will be back from my vacation

frodo: do you think it could be a graph-building problem? and are you able to reproduce this, or is it just on my machine?

Evr doesn't work anymore.
It's two days that video is only a black screen (both tv and video player), with old and new tsreader.
With older svns Evr was working.
If I set VMR9 all works OK.
Using Nvidia Forceware 162.22
