Hi,

   Got an uncompressed avi with ARGB frames, each with an alpha channel.

When I render this with media foundation, the frames are decoded, but the alpha seems to be ignored and the frames come out visible, but opaque.

Please could Microsoft supply a sample application that demonstrates video streams that include alpha channels decoding correctly.

Thank you.

Best regards,

Hi,

    MFPlayer fails with playback error 0xC00D36FA when I open a video file on a machine with no audio device installed.

Your other example media foundation players gracefully degrade as expected & play back video with no sound on this system configuration.

Please could Microsoft upgrade MFPlayer so it also gracefully degrades & plays back video when no audio device is installed.

Thanks in advance.

Best regards,
Steve.

Basically, I have a neat H.264 byte stream in the form of I and P samples. I can play these samples using MediaStreamSource and MediaElement and they play good. I also need to save them as an MP4 file so that the same can be played later using Media Element or VLC. This is how I am trying to do it, using Media Foundation;

I create an IMFMediaSink from MFCreateMPEG4MediaSink; this is my code:

IMFMediaType *pMediaType = NULL;
	IMFByteStream *pByteStream = NULL;
	HRESULT hr = S_OK;
	if (SUCCEEDED(hr))
	{
		hr = MFCreateMediaType(&pMediaType);
	}

	pSeqHdr = reinterpret_cast<UINT8 *>(mSamplesQueue.SequenceHeader());
	if (SUCCEEDED(hr))
	{
		hr = pMediaType->SetBlob(MF_MT_MPEG_SEQUENCE_HEADER, pSeqHdr, 35);
	}
	UINT32 pcbBlobSize = {0};
	hr = pMediaType->GetBlobSize(MF_MT_MPEG_SEQUENCE_HEADER, &pcbBlobSize);

	/*if (SUCCEEDED(hr))
	{
		hr = pMediaType->SetUINT32(MF_MPEG4SINK_SPSPPS_PASSTHROUGH, TRUE);
	}*/
	if (SUCCEEDED(hr))
	{
		hr = pMediaType->SetGUID(MF_MT_MAJOR_TYPE, MFMediaType_Video);
	}
	if (SUCCEEDED(hr))
	{
		hr = pMediaType->SetGUID(MF_MT_SUBTYPE, VIDEO_INPUT_FORMAT);
	}
	if (SUCCEEDED(hr))
	{
		hr = MFSetAttributeRatio(pMediaType, MF_MT_FRAME_RATE, VIDEO_FPS, 1);
	}
	if (SUCCEEDED(hr))
	{
		hr = pMediaType->SetUINT32(MF_MT_AVG_BITRATE, VIDEO_BIT_RATE);
	}
	if (SUCCEEDED(hr))
	{
		hr = pMediaType->SetUINT32(MF_MT_INTERLACE_MODE, MFVideoInterlace_Progressive);
	}
	if (SUCCEEDED(hr))
	{
		hr = MFSetAttributeSize(pMediaType, MF_MT_FRAME_SIZE, VIDEO_WIDTH, VIDEO_HEIGHT);
	}
	if (SUCCEEDED(hr))
	{
		// Pixel aspect ratio
		hr = MFSetAttributeRatio(pMediaType, MF_MT_PIXEL_ASPECT_RATIO, 1, 1);
	}
	if (SUCCEEDED(hr))
	{
		hr = MFCreateFile(
			MF_ACCESSMODE_READWRITE,
			MF_OPENMODE_DELETE_IF_EXIST,
			MF_FILEFLAGS_NONE,
			L"output1.mp4",&pByteStream);
	}
	if (SUCCEEDED(hr))
	{
		hr = MFCreateMPEG4MediaSink(
			pByteStream,
			pMediaType,
			NULL,&pMediaSink);
	}

Then I create an IMFSinkWriter from this media sink using MFCreateSinkWriterFromMediaSink; this is my code:

if (SUCCEEDED(hr))
	{
		hr = MFCreateSinkWriterFromMediaSink(pMediaSink, NULL, &pSinkWriter);
	}
	// Tell the sink writer to start accepting data.
	if (SUCCEEDED(hr))
	{
		hr = pSinkWriter->BeginWriting();
	}

	if (SUCCEEDED(hr))
	{
		pSinkWriter->AddRef();
	}

And then I write every sample to the sink writer with IMFSinkWriter::WriteSample(0, IMFSample); this is my code:

IMFSample *pSample = NULL;
	IMFMediaBuffer *pBuffer = NULL;

	const DWORD cbBuffer = mSamplesQueue.GetNextSampleSize();
	UINT32 isIDR = mSamplesQueue.GetNextSampleIsIDR();
	BYTE *pData = NULL;

	// Create a new memory buffer.
	HRESULT hr = MFCreateMemoryBuffer(cbBuffer, &pBuffer);

	// Lock the buffer and copy the video frame to the buffer.
	if (SUCCEEDED(hr))
	{
		DWORD buffLen = cbBuffer;
		hr = pBuffer->Lock(&pData, &buffLen, 0);
	}
	if (SUCCEEDED(hr))
	{
		hr = mSamplesQueue.Dequeu(&pData);
	}
	if (pBuffer)
	{
		pBuffer->Unlock();
	}

	// Set the data length of the buffer.
	if (SUCCEEDED(hr))
	{
		hr = pBuffer->SetCurrentLength(cbBuffer);
	}

	// Create a media sample and add the buffer to the sample.
	if (SUCCEEDED(hr))
	{
		hr = MFCreateSample(&pSample);
	}
	if (SUCCEEDED(hr))
	{
		hr = pSample->AddBuffer(pBuffer);
	}

	// Set the time stamp and the duration.
	if (SUCCEEDED(hr))
	{
		hr = pSample->SetSampleTime(rtStart);
	}
	if (SUCCEEDED(hr))
	{
		hr = pSample->SetSampleDuration(rtDuration);
	}
	if (SUCCEEDED(hr))
	{
		hr = pSample->SetUINT32(MFSampleExtension_CleanPoint, isIDR);
	}
	//pSample->
	// Send the sample to the Sink Writer.
	if (SUCCEEDED(hr))
	{
		hr = pSinkWriter->WriteSample(0, pSample);
	}

	SafeRelease(&pSample);
	SafeRelease(&pBuffer);

The writing of samples is an iterative code that is called from every sample that I have (I am testing with 1k I and P samples). Now when I call the IMFSinkWriter::Finalize(), it tells me that "0xc00d4a45 : Sink could not create valid output file because required headers were not provided to the sink.". It does create an MP4 file with a very valid size (for my 1k samples, 4.6 MB). 

If it is asking for MF_MT_MPEG_SEQUENCE_HEADER then I am setting them with IMFMediaType::SetBlob(MF_MT_MPEG_SEQUENCE_HEADER, BYTE[], UINT32)

I checked the file with Elecard Video Format Analyzer and the header seems incomplete.

Thanks, Manish

There is a helpful package for WMF use in C# which I am attempting to modify to accept a streaming video over a very local network. This video can be accessed in my tests with VLC, but only via udp://@(address). The example code I'm working with is "BasicPlayback" for C# in WMF; it does not support UDP. All the help I can find online indicates either to use RTP or RTPS - the former of which is also unsupported, and the latter of which does not locate the stream when I try it - or gives me advice of adding a new scheme handler for UDP to the registry.

Unfortunately, Microsoft's "helpful" guide to scheme handling and using the IMF source resolver says to modify the registry and to use an enable command....but doesn't give me enough information to figure out how. The registry editing instructions are here: http (colon) (slash slash) msdn (dot) microsoft (dot) com (slash) en-us (slash) library (slash) windows (slash) desktop (slash) aa371872(v-vx.85) (dot) aspx ((apologies, but MS doesn't let me paste links yet)) but I have had no luck determining how to find out what UDP's CLSID is (or even if there's a specified one, or it's something I need to make up myself). The instructions for configuring a media source ( http (colon) (slash slash) msdn (dot) microsoft (dot) com (slash) en-us (slash) library (slash) windows (slash) desktop (slash) dd206738(v=vs.85) (dot) aspx ) rather unhelpfully demonstrate creating a pointer and using it as an argument, with no indication how to actually USE it. I may be missing something, so please do not hesitate to point out something that might seem obvious that I am missing.

Ultimately, what I need, again, is to be able to enter a udp://@(address) into the URL field of BasicPlayback and have it stream the video coming from that address. I am not opposed to writing my own scheme handler, if I could figure out what one even looks like; the code for existing ones is obfuscated behind dll reference files. I do not know C# well enough to know how to dig deeper than the interface definition, which only has the prototypes for the methods. Searching all files hasn't helped me locate overriding definitions or declarations, either.

Any advice or help is welcome. Thanks!

Hi everyone,

I've got an AverMedia HD Live Gamer capture card for capturing an HDMI plugged video camera.

I've ensured that this capture card supports DirectShow so I've started to build a custom graph in GraphEdit in order to test it's working and then write the code in C++ for use it in my application.

I've connected the graph like that:

AverMedia HD Xbar (crossbar) >  AverMedia HD Capture > AverMedia Encoder H.264 > MPEG-2 Demultiplexer > Microsoft  DTV-DVD Video Decoder > VMR9 (pin: Input 1)

But always I try to run the graph i get the following error:

0x8007048F - Device not connected

Anyone knows why? How can I fix this error to get the capture card into DirectShow?

I don't need to write a file or decode / encode the video stream...only to display it in DirectShow.

A simple application but I cannot see what I'm doing wrong or I'm missing.

Thanks a lot,
Adrià.

P.D.: I've used both AverMedia REC Central and vMix applications and the capture card is working fine.

There is a bug in Media Foundation on Windows 8.1.  It's simple to reproduce, including in Topoedit.

Steps... 

-Add a video capture source (we've tried several - including the AVStream Simulated Hardware Sample)

-Add a EVR

-Connect them

-Play/Run/Start (observe that you get video)

-Stop

-Play/Run/Start (observe that you don't get video)

This was not a problem with Window 8.0.  

I would like to analog sound draw values from windows media player as when the video is being played. May i know if there is such function in visual studio 2012 which can help me do it. Will appreciate if any of your could provide me a link, so I can start a direction. I now totally lost with my project as where to start searching in the field of sound coding.

Thanks

I am trying to get AVC/H264 decoding using the DX11 Video Decoding APIs working. Are there any code samples on how to correctly feed the DXVA2 structures into the buffers to get a correct output image? After days of fiddling around with SPS/PPS information stuffed into DXVA structs i got _some_ image output. But it's flickering and has tons of decoding artifacts.

The only information i found was on DXVA2 in ffmpeg and an MSDN article on how to use the API in general (to implement a MediaFoundation Filter). Then there's a MS PDF on DXVA2. 

Quite interessting that nobody seems to use it - at least in open source projects - while all GPU vendors implement in their drivers...

Any help or hints appreciated.

All the best,

Stephan

Hi, 

I am using the Integrated Camera on Lenovo x201 with Media Foundation.  It works fine the first time I try it , however the next time  even when I call release on the source reader object, it can not get the media source. 

_sourceReader->Release();

// Create a source reader for this file from MediaSource
hr = MFCreateSourceReaderFromMediaSource(_mSource,m_Attributes, &_sourceReader);

IMFMediaType* mType = NULL;
	hr = _sourceReader->GetCurrentMediaType(MF_SOURCE_READER_FIRST_VIDEO_STREAM, &mType);

It fails saying cannot open the device. If I restart my executable it works fine.

Thanks,

Manisha

Hello everybody,

I'm working with MF topology that has multiple video sources. Until now I've been successfully usingMFCreateAggregateSource() to combine them into a single source, since MF can't handle multiple sources in one topology. But now I also want to be able to add/remove certain sources dynamically(without shutting down other sources). Aggregate Source doesn't seem to provide any mechanism  to perform dynamic changes on the underlying media sources. And I can't create a new Aggregate Source without shutting down the previous one (because some of the underlying sources are the same and it returns MF_E_MULTIPLE_SUBSCRIBERS). Hence I can't create a new topology to pass to Sequencer Source.

So what is the best way to go here? Is this even possible?

I've read this 7 year old topic (http://social.msdn.microsoft.com/Forums/en-US/aa0080f0-efd5-4a53-8e03-815cddca2ef8/mf-video-media-source-example), that looks relevant. I guess a custom source with dynamically changing set of streams can do the trick. (I also guess that Aggregate Source works the similar way). Is there a more convenient way other than implementing my own Aggregate Source from scratch?

Thanks in advance.

Dear community,

I would need some help with the media foundation. I have the following scenario:

A rtp multicast ts stream has to be displayed with the WPF media element. I have found the Media Extension (Win8 Store App) example, that includes many examples for custom scheme handler and so on. My idea was to implement a custom (rtp://) scheme handler, that just "forwards" the byte stream to the decoders or just create a custom media source, that cares about decoding. Is this possible or do I need to implement all the decoding myself. As far as I understood the archirecture of  mf it should be possible to just forward the bytes to some mf component, because if i store the raw bytes on my hard disk and name the file something.mpg, the media element plays the stream.

Thanks in advance and sorry if I'm too naive :) but mf is "somewhat" complex... but the only solution to display the stream in a win8 app.

I have a problem with the sink writer to write AAC samples to MP4 sink.

I capture 44.1k stereo float samples.

I use a  IMFTransform resampler to convert them into PCM 16bits stereo samples.

These samples are sent to the MPEG4 sink writer (configured to encode them to AAC samples).

I call WriteSample without problems but nothing is written to the file.

Hello all,

I'm a little stumped on how to achieve my goal of combining Text overlay in a video stream. I'm currently reading and looking at the book "Developing Microsoft Media Foundation Applications" and getting a lot out of it, but in his Transform example he is just injecting a static image overlay to the input video stream of his Transform dll.

I understand the Transform plugins are isolated COM objects from all outside applications. Am I wrong in assuming this could be achieved by the calling application setting up 2 streams to the transform, 1 being the image of the text overlay, and the other being the video stream and then combining the 2 inside the Transform? Am I way off base in this theory or is there another way of sending custom data to the Transform (being the Text Image overlay) somehow other than a stream.

Thanks so much in advance for your responses!

I have a program that creates and accesses Windows Media Playlists (for audio / *.wma files).

Recently, I have tried to set attributes, other than: Title and Author. When I try using SetItemInfo("<attribute>","<attribute value>"), the <attribute> does not save back to the permanent *.wpl file. In other words, if I use for example:

wmpMyPlaylistCollection = AxWindowsMediaPlayer1.playlistCollection
wmpMyPLArray = wmpMyPlaylistCollection.getByName(<SomePlayListName>)

wmpMyPlaylist.setItemInfo("UserCustom1", "ThisIsATest")

and then try and access it:

Debug.Print("UserCustom1: " & wmpMyPlaylist.getItemInfo("UserCustom1"))

This is my output:

UserCustom1: ThisIsATest

And if I use the code:

For IX = 0 To wmpMyPlaylist.attributeCount - 1
  Debug.Print(IX & "). " & wmpMyPlaylist.attributeName(IX).ToString)
Next

one of the Debug.Print statements will produce: UserCustom1

However, if I go back and re-select the wmpMyPlaylist from the library via the first 2 lines of the code:

wmpMyPlaylistCollection = AxWindowsMediaPlayer1.playlistCollection
wmpMyPLArray = wmpMyPlaylistCollection.getByName(<SomePlayListName>)

Then:

Debug.Print("UserCustom1: " & wmpMyPlaylist.getItemInfo("UserCustom1"))

will produce:
UserCustom1: <and a blank here>

and the for next loop:

For IX = 0 To wmpMyPlaylist.attributeCount - 1
  Debug.Print(IX & "). " & wmpMyPlaylist.attributeName(IX).ToString)
Next

will not have the entry: UserCustom1

By doing some research, I found the MSDN Library entry for:

IWMPMedia::setItemInfo method

which states in the "Remarks" section:

If you embed the Windows Media Player control in your application, file attributes that you change will not be written to the digital media file until the user runs Windows Media Player.

So...how can I call the setItemInfo against the playlist, without running it through the embedded "AxWindowsMediaPlayer1".

Anybody know how to do this?

Thanks for your time in advance.

When I look under HKEY_LOCAL_MACHINE\Software\Classes\MediaFoundation\Transforms I do not see the "Video Processor MFT" entry, described in http://msdn.microsoft.com/en-us/library/windows/desktop/hh162913(v=vs.85).aspx . My system is Windows 7 Pro, 64-bit. I see "Color Converter", and many others, but not the video processor. Do I need to install something extra?

I am currently prototyping the ability to remove sections from a video and saving the results using Media Foundation in a C++ program. There is a fundamental flaw in my approach that I'm hoping somebody will have a suggestion for a work-around, or at least an alternative idea that could be used instead (but it must be MF-based, DirectShow is not an option).

The initial approach chosen for the encoding involved the use of the "Source Reader plus Sink Writer" algorithm as briefly outlined in this article: http://msdn.microsoft.com/en-us/library/windows/desktop/ff485861(v=vs.85).aspx

Since there is no transcoding involved, the ReadSample+WriteSample loop is very fast since I can just use the source native MediaType in the sink writer. My initial thought was to just drop the samples[frames] that are within the interval to be cut out of the video. This turns out to be a bad idea because it doesn't take into consideration the compressed format of the video/audio streams. That is, that there are I-frames (a.k.a., key frames) and P-frames (partial frames) and the P-frames are highly dependent on the existence of the preceding I-frame.

In this example, choosing to discard arbitrarily (user) chosen frames, would result in incorrectly rendered frames following the discarded section. It would correct itself upon reaching the next key frame.

[ I ][ P ][ P ][ P ]  [ P ][ P ][ I ][ P ][ P ]  [ P ][ P ][ P ][ I ][ P ][ P ]
                         ^                               ^
                          x    <-   discard   ->   x

My hope was to try to either (a) force the next sample/frame after the cut section to be a key frame, or (b) manually insert a sample as a key frame into the output sequence that represents what the frame would have looked like at the end of the cut.

Regarding (a), this article suggests a way to do that with the MFSampleExtension_CleanPoint attribute, but setting that to TRUE with a sample that is a P-frame does not work (not surprising, I suppose).

And (b) could work, but the trick is to get the desired image and then encode it appropriately for the sink writer. Can't seem to get that to work (including leveraging an H.264 encoder).


So, the ReadSample+WriteSample loop doesn't seem promising. If so, what other approaches, using Media Foundation, would work for removing portions of a MP4 video?

Media Foundation is kind enough to provide these two nifty attributes for trimming: MF_TOPONODE_MEDIASTART and MF_TOPONODE_MEDIASTOP. But there are no equivalents for cutting sections out of the middle.

This code snippet shows the relevant details of the process (omitting most comments, all error checking, and the sink writer creation and stream assignments wrapped in the custom CMFMP4SinkWriter class):

bool Transcode(
   const std::wstring& infile,
   const std::wstring& outfile,
   const std::vector<Interval>& segments )
{
  // 1. Create the IMFSourceReader from the input file

  ATL::CComPtr<IMFSourceReader> mediaSourceReader;
  MFCreateSourceReaderFromURL( infile.c_str(), NULL, &mediaSourceReader )

  // 2. Create the IMFSinkWriter from the output file

  CMFMP4SinkWriter sinkWriter( nullptr );
  sinkWriter.InitializeSinkWriter( outfile.c_str(), false, enableHwTransforms );
  int streamCount = 0;
  sinkWriter.AddMediaToSinkWriter( mediaSourceReader, streamCount );

  // 3. Loop through all the samples

  ProcessSamples( mediaSourceReader, sinkWriter, streamCount, segments );
}


void ProcessSamples( ... )
{
   // Read all samples from the source reader and pass them to the sink writer.

   sinkWriter.StartWriting();

   // Loop as long as there are unfinished (unread) streams (audio and video)
   //
   int nFinishedStreams = 0;

   while ( nFinishedStreams < streamCount )
   {
      ATL::CComPtr<IMFSample> sample;

      mediaSourceReader->ReadSample(
         (DWORD)MF_SOURCE_READER_ANY_STREAM,
         0, &streamIndex, &flags, &timestamp, &sample );

      if ( sample != NULL )
      {
         if ( IsUnCutSample( segments, timestamp, sample ) )
         {
            // Push the sample to the sink writer
            sinkWriter.WriteSample( streamIndex, sample );
         }
      }
      else if ( flags & MF_SOURCE_READERF_STREAMTICK )
      {
         sinkWriter.SendStreamTick( streamIndex, timestamp );
      }

      if ( flags & MF_SOURCE_READERF_ENDOFSTREAM )
      {
         sinkWriter.NotifyEndOfSegment( streamIndex );

         nFinishedStreams++;
      }
   }

   sinkWriter.FinalizeWrite();
}

I would like to read analog sound intensity values from playing a video from windows media player that was created as a platform on Visual Studio 2012. May I know what program, protocol, function in Visual Studio that can help me to do it. Will appreciate if any, could provide me the link or direction. I am new to the sound development. 

hi there

I am tasked with building a camera application for a tablet, using windows desktop.

I found this sample online, which does almost everything i need to, I adapted it to fit my needs, but i need to improve on it with 2 functionalities, which there seem to be close to no documentation or samples around the internet:

Change the resolution of the photo taken

Flip the preview and the photo as the tablet rotates

Thank you for your help.

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
