Default H265 support in wmf

I can't get video from mp4/mkv hevc, only audio... shouldn't this be supported in reaper with wmf? Could you guys confirm this?
I am actually able to run the video with the native player on win10/11 with hevc extension.

Try with vlc or ffmpeg as the first entry in the video decoder list (Reaper program pref - Video). Both work fine here.

They are not as reliable as Media Foundation or at least not on my pc. I had problems with waveform bugs and crashes with both.

I just tried Reaper v7.33+dev0218 and Hevc video finally works, thanks.

Reaper has the same problem with Vorbis (Web Media Extensions) and AV1 (AV1 Video Extension) in wmf. Meanwhile, Vp9 (VP9 Video Extensions) and Opus seem to work, but they have some shady code in source properties.
Check these (videos work correctly on native win10/win11 player)->

Test Vorbis:https://drive.google.com/file/d/1Dts...ew?usp=sharing

Test AV1OPUS: https://drive.google.com/file/d/10s4...ew?usp=sharing

Test AV1AAC:https://drive.google.com/file/d/17ij...ew?usp=sharing

Test VP9OPUS: https://drive.google.com/file/d/1AG2...ew?usp=sharing

Test VP9AAC:

If by "shady code" you mean "video format: {a bunch of letters and numbers}", that's fine, it means even though REAPER doesn't recognize the format, the decoder can still successfully decode it.

Yeah, i got that reaper had at least figured out what it was, according to this list https://gix.github.io/media-types/.
And to finish, i just tested also MPEG-2(MPEG-2 Video Extension) and Dolby AC-3(Microsoft Dolby Digital Plus Decoder) and they seem to work like VP9 and OPUS, not recognizing the format.


Test Mpeg-2AC-3: https://drive.google.com/file/d/1XdG...6p4-g6uf_/view

So the ones that absolutely don't work, just like hevc before, are AV1 and Vorbis.
