H265 GUID does not match in UVC Camera #436

Closed goldscu closed 3 years ago

goldscu commented 3 years ago

The GUID of H265 data read by UVC camera does not match. The GUID of DirectShow is {35363248-0000-0010-8000-00AA00389B71}, while the GUID of HEVC in LAV is {43564548-0000-0010-8000-00AA00389B71}, so it cannot Decoding, please solve this problem.

The GUID that LAV uses is actually correct (FourCC "HEVC"). There are multiple FourCCs for same format. What you are asking is to additionally support FourCC "H265".

I can't upload a short sample file here, because I discovered this problem while debugging the uvc camera, and I need to debug with hardware equipment. When using DirectShow, because the two GUIDs of the subtype of AM_MEDIA_TYPE are inconsistent, the decoder Pin cannot be connected with source filter's Pin. Other people’s inability to decode H265 should be caused by this problem. I mean can you support the GUID read by DirectShow{ 35363248-0000-0010-8000-00AA00389B71}

I am not the developer. Just trying to help clarify things.

Which source filter are you using?

The source filter is DirectShow offiial. When insert USB camera, the driver auto registed. Thanks for you helping!
