Hi ,
My requirement is not play the Audio data only video should get play.
If I dont pass the Audio data from Mine custom Audio MFT and pass only the Video data
from custom Video MFT, the call to Processoutput method in Video MFT get stopped.
How I can achieve the same scenario?
Best Regards,
Sharad
We are experiencing a problem where the active x control will randomly wait 30 seconds before actually playing a wav file from an http resource. In the web page we are able to talk to the active x control, and get information from it, but it does not start playing until about 30 seconds after we told it to play.
In order to get more information about what might be happening we would like to see some logging. Is there any way to enable some logging and see what is going on in the windows media player active x control?
My apologies if this is not the correct place to post this question.
Hi guys,
I am writing a video processing application. I am utilizing a media session. My pipeline consists of source reader, decoder MFT (used by MfEnum, I query the MFTs capable of outputting one of my 4 desired video formats), Color Converter DSP (to convert YUY2, NV12, YV12 outputs of the decoder into RGB32), and my custom sink. My custom sink writes the samples of with no issues. I am planning on adding a variation to my pipeline. I want to inject an H264 encoder between the color converter and the sink. In this scenario my custom sink will be replaced by the built in MPEG4 sink.
Having said above, my original pipeline without the encoder and MPEG4 sink works fine.
I query the system for an H264 encoder with YUY2 input and H264 output and it returns one match. I create an instance and try to set up the input and output types. SetOutputType fails. MFTrace does not give me much except it fails.
I tried both using an already setup Media Type and creating the media type from scratch. Per the documentation I have filled up all of the pieces. I am setting the output first and then the input. Only thing is that I am doing this on Windows 8. I need to setup my VM to check on windows 7.
Here is the sample code.

FYI _inputInfo is a bit bucket that holds the information retrieved from the source reader.
It holds frame size, frame rate, bit rate
Any help is much appreciated.
Any ideas?
(Note: I originally posted this question in the Windows Apps with C++ forum about 3 weeks ago, but received no replies. I realized quickly that this might be a better forum for this, but wanted to let that question run its course before posting again here. So any help you all could provide would be VERY much appreciated.)
I am using a C++/CX component to encode video using IMFSinkWriter, and everything works fine when I encode using the WMV3 codec, but when I try to use the H.264 codec I get E_CHANGED_STATE (0x8000000c: "A concurrent or interleaved operation changed the state of the object, invalidating this operation.") errors. I can't find any reason to believe this is a threading issue, which was my first thought: the component is being called from an async/await C# method, but everything awaitable is being awaited, as far as I can see, and there's no other threading-like behavior going on in the app.
My second thought was that somehow the sink writer's throttling (on by default) was being turned off. But this doesn't seem to be the case. In fact, I tried to explicitly enable throttling, but this didn't have any effect:
spAttr->SetUINT32(MF_SINK_WRITER_DISABLE_THROTTLING, false);
The encoding source is an RGB32 stream, and I am encoding at a 1.5Mbps bitrate, 25 FPS.
The error happens every time I try to encode a video of any real-world length: it'll usually pop up before it gets about 10% of the way through a 5 minute output file. However, it isn't entirely deterministic: sometimes it will get partway through the third (of 58) segments, while other times it will happened on the first.
None of these problems affect WMV encoding. Can anyone offer any suggestions for things to try?
Additional note: I have seen some references that I might need to supply some metadata (a sample description box) with the video, but I can't find any documentation on this that I can understand. As indicated I can encode WMV without getting this error (usually-- I think I've seen it once or twice in the long history of testing this component), and all I would like to do is provide an alternative format for my users. Could the lack of this metadata be causing this, and if so are there any accessible tutorials on constructing it?
I'm trying to investigate 'MFCaptureToFile' sample on Windows7 & VisualStudio2008. It's for understanding to use IMFSinkWriter. My purpose is encode movie to H264 by IMFSinkWriter.
And I changed TARGET_BIT_RATE from (240*1000) to (10*1024*1024). It is passed to IMFMediaType through MF_MT_AVG_BITRATE.
As the result, I can change the bitrate of WMV by above changing. But H264 keeps a same bitrate(around 210kbps).
I tried to run same program on Windows8, it works well. I'm not sure why it isn't working on Windows7. Do we have a method to change H264's bitrate on Windows7?
And I've submitted this question on wrong page of MF_MT_AVG_BITRATE. How can I delete it? I can't delete it from "Edit Post"...
Hi,
I have written an application to capture from UVC compliant cameras using Media foundation's SourceReader.
A part of the application closes down and releases the camera and then restarts it. Below are the code snippets desribing it:
Initialize Source reader:
hr = MFCreateSourceReaderFromMediaSource(_mSource, _mAttributes,&_sourceReader);
Get a frame synchronously:
hr = _sourceReader->ReadSample(MF_SOURCE_READER_FIRST_VIDEO_STREAM, 0, // Not using MF_SOURCE_READER_CONTROLF_DRAIN flag because we are not going to Buffer samples&actStreamIndex,&actStreamFlags,&timeStamp,&mediaSample);
We now clear & release the camera:
SafeRelease(&_sourceReader);
SafeRelease(&_mSource);
SafeRelease(&_mAttributes);
SafeRelease(&_nativeMediaType);
for (DWORD i = 0; i < _count; i++)
{
SafeRelease(&_mmDevices[i]);
}
CoTaskMemFree(_mmDevices);I then re-initialize the camera with a different media type and call ReadSample again.
This work flow works with most cameras, but, with lifecam VX-3000, the ReadSample call after re-initializing returns the following failed HRESULT : 0x80070004
HRESULT_FROM_WIN32(ERROR_TOO_MANY_OPEN_FILES): The system cannot open file.
Am I missing anything while releasing the device? Thanks in advance for any ideas/suggestions on this.

I am trying to determine how AsfLeakyBucketPairs data in an ASF file is generated. We have a legacy device that will not play an ASF stream unless this field is present. However, we can populate the field with garbage and the device will play the stream properly. Would like to generate the correct leaky bucket data. I looked at the leaky bucket field in the VC1 sequence header but it only has 1 pair and the value does not correlate to any of the pairs in the data. Is there a spec that scribes how to generate the AsfLeakyBucketPairs data for the Asf file?

Hi
I am currently trying to change the max key frame interval of the media foundation H.264 encoder by setting the MF_MT_MAX_KEYFRAME_SPACING on the output media type of the encoder. But every video that I create seems to always default to a key frame interval
of 2 seconds.
My current scenario entails setting up a SinkWriter with an uncompressed YUY2 input media type and a H.264 output media type.
The video source is 25fps so for a 1 second key frame interval I set the MF_MT_MAX_KEYFRAME_SPACING attribute on the H.264 output media type to 25 frames. But the H.264 encoder still outputs the key frames every 2 seconds(50 frames).
I also tried setting it to a higher 250 frames(10 second) interval and with the same result.
Am I missing some setting somewhere or is the max key frame interval not configurable on the media foundation H.264 encoder?
I have included two trace statements from my tests with the SinkWriter below:
1. The Media Foundation H.264 encoder being created.

Hi, I am reading SD PAL sized avi files that are 4:3 and 16:9 display aspect ratio but am not able to read this from the file.
When I call MFGetAttributeRatio() with GUID MF_MT_PIXEL_ASPECT_RATIO this returns 1:1. The MFVideoFormat also contains 1:1 and the aspect ratio in VideoInfo2 is 5:4 for both 4:3 and 16:9. I understand that the aspect ratio in VideoInfo2 is the storage aspect ratio and that I need the pixel aspect ratio and by multiplying this with the storage aspect ratio this then gives the display aspect ratio but I have not been successful in reading this value. Also the interlaced field is always progressive which is incorrect, it should be interlaced.
Analysing the output from MFTrace when attached to windows media player on Windows 7 I can see that the MF_MT_PIXEL_ASPECT_RATIO value on calls to setInputType and setOutputType will change from 1,1 to 16,15 and then 64,45, the latter when multiplied with 5:4 gives 16:9.
I have started using media foundation and have read the article: http://msdn.microsoft.com/en-us/library/bb530115(v=VS.85).aspx
but this does not explain how I obtain the source display aspect ratio I am after.
Any suggestions and help much appreciated as I think I am not the only person who is struggling with this. To give a little more information I am using Media Foundation to import AVI files into our editor software and I can read all other video information such as size and frame rate but need to know the interlace mode and display aspect ratio before reading the samples into our application.

} I want to create a DXD11 pipeline for getting streams from the recorded video to send it to ssfsdk api method ( Smooth Streaming Format SDK)
hr = SSFMuxAddStream(hSSFMux, &streamInfo, &pCtx->dwStreamIndex);
And later using
hr = SSFMuxProcessOutput( pCtx->hSSFMux, pCtx->dwStreamIndex, &outputBuffer );
we will get chunks (streams) in output buffer.
I wanted to write these streams to publishpoint ( http://<server>/<pubpoint>/Streams(<identifier>) ) for live streaming.
I have found below code for this.
fResult = WinHttpSendRequest(
hHttpRequest,
szAdditionalHeaders,
ARRAYSIZE(szAdditionalHeaders)-1,
WINHTTP_NO_REQUEST_DATA,
0,
0,
NULL
);
if( !fResult )
{
hr = HRESULT_FROM_WIN32( GetLastError() );
goto done;
}
And here’s an example of a function for posting HTTP chunks (assuming WinHTTP is operating in “synchronous” mode):
HRESULT WriteToSmoothStreamOutput(
__in HINTERNET hHttpRequest,
__in_ecount(cbData) LPCVOID pbData,
__in ULONG cbData )
{
HRESULT hr = S_OK;
BOOL fResult = FALSE;
DWORD cbWritten;
char szHttpChunkHeaderA[32];
char szHttpChunkFooterA[] = "\r\n";
//
// Send the HTTP Chunk Transfer Encoding chunk-start mark
// Observe the use of UTF-8 strings.
//
hr = StringCchPrintfA(
szHttpChunkHeaderA,
ARRAYSIZE(szHttpChunkHeaderA),
"%X\r\n",
cbData );
if( FAILED(hr) )
{
goto done;
}
fResult = WinHttpWriteData(
hHttpRequest,
szHttpChunkHeaderA,
(DWORD)( strlen(szHttpChunkHeaderA) * sizeof(char) ),
&cbWritten
);
if( !fResult )
{
hr = HRESULT_FROM_WIN32( GetLastError() );
goto done;
}
//
// Send the actual chunk data
//
if( cbData > 0 )
{
fResult = WinHttpWriteData(
hHttpRequest,
pbData,
cbData,&cbWritten
);
if( FAILED(hr) )
{
hr = HRESULT_FROM_WIN32( GetLastError() );
goto done;
}
}
//
// Send the HTTP Chunk Transfer Encoding chunk-end mark
//
fResult = WinHttpWriteData(
hHttpRequest,
szHttpChunkFooterA,
(DWORD)( strlen(szHttpChunkFooterA) * sizeof(char) ),
&cbWritten
);
if( FAILED(hr) )
{
hr = HRESULT_FROM_WIN32( GetLastError() );
goto done;
}
done:
return( hr );
} But WinHttp is unable to connect and write streams to publishpoint for live streaming.
Please suggest for the above requirement.

But WinHttp is unable to connect and write streams to publishpoint for live streaming.I have a H264 encoded video (self-generated) which can not be played by Windows Media Player 12, but by other video players such as VLC.
Unfortunately Media Player (version 12.0.7601.18526) does not provide any (error-)information why the video isn't played - the player is in play mode, the progress bar flickers, but unfortunately nothing to see.
The non-playing video of inetreest can be found here: http://www.mediafire.com/download/x12gn3u5bmn6c1u/CapturedVideo-00037.ts
Used H264 analysis tools indicate no errors, so it seems that the file content is not completely wrong - maybe only a flag needed by Windows Media Player is not set correctly.
Thanks in advance for any kind of helpful response.
Hello There,
I am using winmm library for audio output. but in windows 7 64 bit system my application is crashes on waveoutopen api. How to manage this api with 32 and 64bit?
Thanks and Regards.
In the Windows 8 and 8.1 email program, it would be good if I could choose a default text size without having to choose the text size each time I write to a friend who is visually impaired.
Thanks!
