directshow Bluray disc navigator filter base on libbluray

[cb2000]

I suggest to find out the max frame rate of all input stream.

but it still has a problem, there maybe a condition that, begin stream with no video in stream 0 and the frame
rate is 0, then it appear after some time that other stream had produce some frame.

The refresh rate might bare no relation to the video frame rate.

I want to set the

IMFMediaType *mt = NULL;

if(GetOutputCurrentType(0,&mt)==S_OK) 
{
    MFRatio fps;

    if (SUCCEEDED(GetFrameRate(mt, &fps)) && (fps.Numerator != 0) && (fps.Denominator != 0))
    {
    MFFrameRateToAverageTimePerFrame(fps.Numerator,fps.Denominator,(UINT64*)&m_hnsFrameInterval);

 }
 }

If i set the proper
SetSampleDuration()

My jerky problems in menus go away

In the example code for EVR presenter, if there is no frame rate, it just guesses 30fps. Trouble is when set to the refresh rate, or 75fps here, the menus are unusuably slow. Takes 1-2 seconds to respond to key presses. If i set to the correct 24fps, everything works fine.

How can we find the input frame rate?

yeah I tried that, I just got attribute not found. My desktop refresh rate is set to 75, maybe that is too fast for DXVA or something. I tried capping it at 10010000 / 60; (59.57) fps at the problem went away totally. I'll do some more testing.

[dukey]

Done some more debugging of this problem. I think the issue is the time stamps are broken.
When I hit buttons on the keyboard for the menu, I can see them coming through the function
OnProcessInput()

at the right time. But the time stamps are 2~ seconds off the stream time of stream 0. So I have a menu delay of 2~ seconds.

Time stamps looks something like this

sample time 734290000 stream 0
sample time 734490000 stream 0
sample time 734690000 stream 0
sample time 734890000 stream 0
sample time 735090000 stream 0
sample time 735290000 stream 0
sample time 735490000 stream 0
sample time 750080834 stream 2           <---- stream 2
sample time 735690000 stream 0
sample time 735890000 stream 0
sample time 736090000 stream 0
sample time 736290000 stream 0

I see you are using
pFilter->GetStreamTime();
In a few places. I am not sure how accurate that is. In the documentation it says

samples with start timestamps of this time or before should be rendered by now

[cb2000]

when start streaming, no video yet, so no frame rate on stream 0,
after som time, video comes out, mixer will be notified by SetInputType with stream id 0, then should recheck the frame rate.
the frame rate of overlay is always not set in current dslibbluray.

Maybe cause by not optimized DXVA/D3D process and no frame drop process in the mixer now, so it cannot achieve so high frame rate.

I thought originally the problem was high frame rates too. But if i set the desktop refresh rate to 60hz, and the interval time to 60hz, then the problem comes back. I am guessing the issue is in the time stamp generation in the source filter, since the subimages render are rendered immediately, but don't display until the time catches up.

[cb2000]

the source filter lack quality-control process also. yes it may cause video time always in the past

Well, I fixed the issue. I rewrote the EVR scheduler to drop late frames. Problems has gone away, menus work beautifully. Can now get onto more productive testing

@dukey after your changes (rev98->101) I can't exit demo_player ! It stops responding after "stop" and it's crashing when trying to exit ! With rev 97 everything it's OK with the same BD
Please fix this

[dukey]

alright i'll look into it. I haven't made any radical changes. By the way, make sure you rebuild the demo_player, as I changed the control interface.

Thanks
I've rebuild everything. Also on a new system (just windows ) I'm getting "ActiveMovie Window: demo_player.exe - System Error ...MSVCR71.dll is missing ..." which I don't know if it was there before, but can you also do a static linking please ?

I checked all the dlls and none depend on that C run time library. Actually that's quite an old library, visual studio 2010 uses a much newer one. You can use
http://www.dependencywalker.com/
to find out which dll is using that dependency. It might be a codec you are using perhaps.
Since you can compile the code yourself.



Sets the run time lib. The dll ones are dynamically linked.

Sorry you're right was a decoder problem

Also the "stops responding / can't exit" it's not decoder related (happens with FFD & LAV & arcsoft)

I'll upload a binary you can test. I rebuilt the program and tried making it crash but can't replicate it.

You need to wait for the main movie to start then -> stop -> Exit

[dukey]

Okay will check it out.
You can try changing
while (true) to while(m_Exit)
and removing

if(m_Exit)
break;

Worst won't even start playing

(Just to be sure BDSource.cpp line 356 -> no?)

[dukey]

does this happen with all your blurays ? Or just this particular frozen planet one.
I see it throws an exception when the frozen planet one starts to play the main title
