My Windows MFC application has a function to export a video file.
And it can select encoding format (via WMV or MP4) and frame size.
But, Unfortunately when i tried to export MP4 file which is set large frame size, everytime MF_E_INVALIDMEDIATYPE happened.
Simply put, here is the result when i tested in each case.
WMV
- 640 x 480 ... OK
- 640 x 576 ... OK
- 1280 x 720 ... OK
- 1280 x 720 ... OK
- 1920 x 1080 ... OK
- 2048 x 1556 ... OK
- 4096 x 2160 ... OK
MP4
- 640 x 480 ... OK
- 640 x 576 ... OK
- 1280 x 720 ... OK
- 1280 x 720 ... OK
- 1920 x 1080 ... OK
- 2048 x 1556 ... MF_E_INVALIDMEDIATYPE
- 4096 x 2160 ... MF_E_INVALIDMEDIATYPE
And here is my code.
HRESULT hr = S_OK;
TIFF *out;
IMFSinkWriter *pWriter = NULL;
IMFMediaType *pMediaTypeOut = NULL;
IMFMediaType *pMediaTypeIn = NULL;
DWORD streamIndex;
hr = MFCreateSinkWriterFromURL(filename, NULL, NULL, &pWriter);
// Set the output media type.
if (SUCCEEDED(hr))
{
hr = MFCreateMediaType(&pMediaTypeOut);
}
if (SUCCEEDED(hr))
{
hr = pMediaTypeOut->SetGUID(MF_MT_MAJOR_TYPE, MFMediaType_Video);
}
if (SUCCEEDED(hr))
{
if (exportMethod == ExportFormatWAV) {
hr = pMediaTypeOut->SetGUID(MF_MT_SUBTYPE, MFVideoFormat_WVC1);
}
else if (exportMethod == ExportFormatMP4) {
hr = pMediaTypeOut->SetGUID(MF_MT_SUBTYPE, MFVideoFormat_H264);
}
}
if (SUCCEEDED(hr))
{
hr = pMediaTypeOut->SetUINT32(MF_MT_AVG_BITRATE, 12 * 1000 * 1000); // 12M
}
if (SUCCEEDED(hr))
{
hr = pMediaTypeOut->SetUINT32(MF_MT_INTERLACE_MODE, MFVideoInterlace_Progressive);
}
if (SUCCEEDED(hr))
{
hr = MFSetAttributeSize(pMediaTypeOut, MF_MT_FRAME_SIZE, m_width, m_height); // e.g. 4096 x 2160
}
if (SUCCEEDED(hr))
{
hr = MFSetAttributeRatio(pMediaTypeOut, MF_MT_FRAME_RATE, m_fps * 100, 100);
}
if (SUCCEEDED(hr))
{
hr = MFSetAttributeRatio(pMediaTypeOut, MF_MT_PIXEL_ASPECT_RATIO, 1, 1);
}
if (SUCCEEDED(hr))
{
hr = pWriter->AddStream(pMediaTypeOut, &streamIndex);
}
// Set the input media type.
if (SUCCEEDED(hr))
{
hr = MFCreateMediaType(&pMediaTypeIn);
}
if (SUCCEEDED(hr))
{
hr = pMediaTypeIn->SetGUID(MF_MT_MAJOR_TYPE, MFMediaType_Video);
}
if (SUCCEEDED(hr))
{
if (exportMethod == ExportFormatWAV) {
hr = pMediaTypeIn->SetGUID(MF_MT_SUBTYPE, MFVideoFormat_RGB24);
}
else if (exportMethod == ExportFormatMP4) {
hr = pMediaTypeIn->SetGUID(MF_MT_SUBTYPE, MFVideoFormat_RGB32); // Because H264 requires
}
}
if (SUCCEEDED(hr))
{
hr = pMediaTypeIn->SetUINT32(MF_MT_INTERLACE_MODE, MFVideoInterlace_Progressive);
}
if (SUCCEEDED(hr))
{
hr = MFSetAttributeSize(pMediaTypeIn, MF_MT_FRAME_SIZE, m_width, m_height); // e.g. 4096 x 2160
}
if (SUCCEEDED(hr))
{
hr = MFSetAttributeRatio(pMediaTypeIn, MF_MT_FRAME_RATE, m_fps * 100, 100);
}
if (SUCCEEDED(hr))
{
hr = MFSetAttributeRatio(pMediaTypeIn, MF_MT_PIXEL_ASPECT_RATIO, 1, 1);
}
if (SUCCEEDED(hr))
{
hr = pWriter->SetInputMediaType(streamIndex, pMediaTypeIn, NULL); // This line returns MF_E_INVALIDMEDIATYPE
}
// Tell the sink writer to start accepting data.
if (SUCCEEDED(hr))
{
hr = pWriter->BeginWriting();
}
I want to export a large sized video of MP4 as well.
Does anyone know a solution against this problem?
