Project IntelQuickSyncDecoder.vcxproj not found #440

Closed francescoBLT closed 3 years ago

francescoBLT commented 3 years ago

Hi I'm attempting to compile LAV filters with VS2019. I didn't found this project IntelQuickSyncDecoder.vcxproj when loading LAVFilters.sln. Should I download and install Intel Media SDK ? Please can you supply detailed instruction for compiling ? My target is to contribute (if you agree) adding two methods to ILAVFSettings interface that allow to select between different audio tracks. Usually mxf files have 8 or 16 audio tracks each one with 1 channel. When I play such mxf files the output pin gives only first track, so I can listen only 1 audio channel in track 1. Having two method: STDMETHOD(GetAudioStreamsNumber)(int *iAudStrm) = 0; STDMETHOD(SetCurrentAudioStream)(int iAudStrm) = 0; Is possible to detect number of audio streams and select one of them.

The filter already supports the standard IAMStreamSelect interface for selecting the audio track.

To fix compilation issues, use Git to clone the repository and checkout all submodules.

Thanks for the fast response. The IAMStreamSelect is not reported in developer_info directory. This is why I create this issue.

IAMStreamSelect is a standard Microsoft interface. Only custom interfaces are documented there.
