HEVC video decoding broken with B-frames
When Edge Chromium playing HEVC video, sometimes video will be similar to stuttering but audio is normal. To find out the cause of the problem, I test to playback many HEVC video, include videos ...
does you have the link of a video who do that (for reproducing purpose, if you report it by the browser don't forget this)
I encoded a video in the HEVC codec. I added the file to this message.
To test this, you can make a simple HTML file that plays this video in the Edge browser.
<body>
<video src="PathToVideo\BigBuckBunny.mp4" type="video/mp4" controls></video>
</body>
- I just drag and dropped this onto an Edge tab and i get extremely laggy playback

700KB H.265 clip with HEVC extension installed on Windows (.MP4)I can also reproduce it with your sample.
I can also confirm with certainty on my end that it has to do with the HEVC b-frames because when I encode a video with "b-frames=0" it plays fine without any stutter.
- i confirm this problem as well (and b-frames=0 too).
