Hello, I tested some files in MPEG-4 video format, why not support hard decoding?

Hi, hard decoding works witn MPEG-4 files in my case. Probably it depends on concrete file, hardware etc. For the time being I've added a few more DXVA2 modes GUIDs.

Hello, my corresponding video file decoder ID is AV_CODEC _ ID_MPEG4, I checked, why the dxva2 file does not have the corresponding GUID？

Sttill, it looks like it depends. Generally I see "H.264/MPEG-4 AVC codec" tags inside such files, so probably they fall under the H.264 category.
