Hi all,

I am using Windows Media Player control v.12.0.9600.16384 on my Windows Desktop application which is actually a custom mp3 player. How can I enableCrossfading feature on windows media player control with C#? Also, I want to enableAuto Sound Leveling which I think it should be a relative process to Crossfading. I searched a lot of articles and forums but I couldn't find any C# code about using these two features.

Thanks a lot,
Peter

According to this white paper (http://msdn.microsoft.com/en-us/library/windows/apps/dn466732.aspx), as of Windows 8.1, the AppX PlayReady Client can be used in desktop apps:

"AppX Frameworks are normally restricted to use by Windows Store app only.  In Windows 8.1, the Microsoft PlayReady app  package can be used by desktop or new experience desktop browsers."

Is there any sample code or guidance on how to actually achieve this using the media engine?

Regarding the MFCaptureD3D sample from the media foundation examples, which can be found here

http://msdn.microsoft.com/en-us/library/windows/desktop/ms702261%28v=vs.85%29.aspx

The Timestamp in the OnReadSample is has the same value as the attribute MFSampleExtension_DeviceTimestamp from the sample, but how can I interpret this value ?

I need to translate this timestamp to the system time or convert it to a DateTime object.

Hello there. I have an IP camera which gives me h264 stream. Now this h264 stream plays just fine in VLC but it doesn't play in WMP12. It gives the error that the player doesn't support the specified protocol and we should try different protocol. Now I tried registering wmnetmgr.dll but in vain. what should I do to run this h264 stream in windows media player 12? Thanks.

Hi all,

I am very much new to media foundation technologies and I want to implement the OpenMAX IL plug-ins for Media Foundation (e.g integrating audio decoder OMX component into audio decoder MFT). can someone guide me how to do that, like mapping of the OMX calls to MFT calls etc.. Any guidelines or help would be appreciated. Does anybody help me with the some sample code :) ? 

waiting for the positive response...

I am trying to achieve seamless video playback using the IMFSequencerSource. So far I have been able to create a player and a playlist to display content. but whenever I add multiple files before it plays the next video a white flash occurs for a split second before the next video plays. I absolutely need seamless uninterrupted video playback and don't know where to go from here. Any guidance on the subject would be greatly appreciated.

Hello all,

I am attempting to create a media source based on the Mpeg1Source sample.

My source is a live source. For the time being, I will be outputting frames that are generated internally.

 

I am following the guides from msdn:

Writing a Custom Media Source

http://msdn.microsoft.com/en-us/library/windows/desktop/ms700134(v=vs.85).aspx

Case Study: MPEG-1 Media Source

http://msdn.microsoft.com/en-us/library/windows/desktop/ee318417(v=vs.85).aspx

and looking through the mpeg1source sample code. I see how the source is registered in the registry as a byte stream handler.

 

My question is, how do I register my live source component? is there documentation for this?

I am familiar with DirectShow filter registration, but Media Foundation is a new game to me!

 

Thank you in advance.

jimmy

Media Foundation Implementing Callbacks

So I've looked through the samples for the Media Foundation audio and they basically have all the functionality I need except for they don't really implement a callback for when the audio buffer is empty. Basically I made some simple oscillators for a synthesizer I am developing and I need an callback method to refill the buffer. Thankfully someone sort of did most of the work for an example they were building for BUILD2014 and posted the code on github.

https://github.com/jolson88/BeatBuilder/blob/master/BeatBuilder.Shared/AudioRenderer.cpp

Problem is I just don't know enough about the asynchronous callbacks and the documentation for them just isn't clear to me. Also the above linked example doesn't quite work since it requires /clr or /ZW in the command line for his implementation AsyncCallback.h and I am using openFrameworks which conflicts with both. 

Really all I need is to implement his function OnRenderCallback(IMFAsyncResult*result)but that's where I sort of hit a wall. Could I just make a pointer to that function from the invoke method in IMFAsyncCallback? and how does it know to go to that callback function? I don't see how the pointer and event handle direct there each time the buffer is empty.

I'm using IMFSourceReader to grab samples on an audio file.

I want to be able to seek anywhere in the audio timeline.

I have this function which sets the position:

void Seek(Windows::Foundation::TimeSpan position)
{
    HRESULT hr;

    PROPVARIANT var;
    hr = InitPropVariantFromInt64(position.Duration, &var);
    ThrowIfFailed(hr);
    
    hr = m_pSourceReader->SetCurrentPosition(GUID_NULL, var);
    PropVariantClear(&var);

    ThrowIfFailed(hr);
}

the position is tied to a slider between 0 and the audio max time obtained from:

Windows::Foundation::TimeSpan GetDuration()
{
    PROPVARIANT var;
    PropVariantInit(&var);

    HRESULT hr = m_pSourceReader->GetPresentationAttribute(MF_SOURCE_READER_MEDIASOURCE, MF_PD_DURATION, &var);
    ThrowIfFailed(hr);

    LONGLONG hnsDuration;
    hr = PropVariantToInt64(var, &hnsDuration);
    ThrowIfFailed(hr);

    PropVariantClear(&var);

    Windows::Foundation::TimeSpan timeSpan;
    timeSpan.Duration = hnsDuration;
    return timeSpan;
}

whenever I change the slider position it calls Seek(slider.Position.ToTimeSpan()) (in pseudo code)

But it doesn't work.

the next sample I read using

m_pSourceReader->ReadSample((DWORD)MF_SOURCE_READER_FIRST_AUDIO_STREAM, 0, NULL, &dwFlags, &_timeStamp, &pSample);

_timeStamp : does not reflect the seeked position.

What am I missing here ?

thanks!

TL;DR: See the section "So My Questions Are:" - This is very long, thanks for looking.
 
I am attempting to build a live preview/recording application using Media Foundation.  I am attempting to use the Media Session, with an aggregate source containing a webcam+microphone sources. Everything works the first time I run the session (preview only), but I am unable to restart the session.  

When the session stops, I see the Sample Grabber Clock stop, and end of Stream notifications, but when the session restarts, I receive the session start message, and see basically the same events, including an OnClockStart event for both media sinks, but the Video source appears to never restart delivering frames.  A picture of the topology is included at the end, along with some MFTrace output.

I have tried pausing the session, stopping the session, and also attempted to unload the session and re-create it. When re-creating the session I was unable to create a new aggregate source, indicating I did not properly release it.

Also, I note that I have not taken any steps to mark the Source Nodes as live sources, I assume that would happen automatically?

So, My Questions are:.

1. What is necessary for me to restart an IMFMediaSession containing live sources?
   
2. What steps are necessary for me to unload the topology in order to build a new one? Clearing the session on the topology and releasing all of my smart pointers is not enough. Perhaps I need to iterate the aggregate source, extract the individual media sources and then call Shutdown on each?

And here is the attempt at restarting. The only differences that I see are that the presentation clock is not re-initialized, i.e. the clock is not attached again (it is not detached, as far as I can see).   I see the two OnClockStart events for the sinks.  The Audio Branch appears to deliver frames, but we never see any frames delivered from the video source:

If I try clear the topology between runs, i cannot recreate the Aggregate source.  I'm thinking that is a clue to the above problem of not being able to restart....

I guess I need to iterate across the aggregate source, extract the IMFMediaSource pointers, and then call IMFSource->Shutdown() when I release the topology?

I have a requirement in that the video files are stored in the database. So is there anyway to play the video from the stream without saving into the file using windows media player

Thanks

Howdy!

I used the transcode sample to create a small utility that converts WAV files to WMA. I'm having an issue, though, that the files fairly often end up a half second short. Any ideas?

Hi,

I have an application where you can have multiple areas where videos are played. I sued the media session for playback. When playing my application asks with a frequency of 10 Hz where the video is so that it can display the current position to the user. 

I have used something like this: 

  HRESULT hr = S_OK;
  IMFClock *pClock = NULL;
  IMFPresentationClock *pPrClock = NULL;

  hr = m_pSession->GetClock(&pClock);
  if (FAILED(hr))
  {
    return MF_E_NO_CLOCK;
  }
  else
  {
    do 
    {
      hr = pClock->QueryInterface(IID_PPV_ARGS(&pPrClock));
      BREAK_ON_FAIL(hr);
      hr = pPrClock->GetTime(llCurrentPossition);
      BREAK_ON_FAIL(hr);
    } while (false);    
  }

  SafeRelease(&pClock);
  SafeRelease(&pPrClock);
  return hr;

If I use only one video then it is ok. I does what it should and I get the correct time. The problem arises when I have more than one area with a video in it. The areas are in different objects that use media foundation.

In the 2 video scenario when I query for the current time I sometimes get the correct value and sometimes I get 0 (in the middle of the video). Does somebody have an explanation for this behavior? What is more confusing to me is that I don't get any error code. The returned HRESULT is S_OK.

Thanks!

I am writing a system that displays multiple short videos taken back to back. My code is based on player.cpp example.

At the end of each video, there is a black flash on the video screen. Is there any way of holding the last frame of the video that just completed in the window while the next video is starting?

Can anyone explain to me how to set this to change the order of channels.

Using the standard is not mixing well with my receiver.

So I want to have the ability to reorder the channels to match what I am looking for.

Using Topoedit, I see the standard has a value of 63, or 111111 in bits.

If it 63 is in Hex, then in bits it is 1100011

In all the sample code on the net I have seen, it is set to 1.
