Chromium vaapi: video turns black seconds after pause

Support Graphics & Display
1

Videos turn black a few seconds after pausing in Chromium when hardware decoding is enabled via --enable-accelerated-video-decode. The issue occured after updating to chromium 86 and still persists with 87 version. Google-chrome-canary have this problem too.
I am using h264fy extension because my videocard does not support vp9 hardware acceleration. There is no such problem in Firefox and hardware video decoding works fine there.

Hi @Gafpdlas, and welcome!

I don’t give myself away as an expert and I might be completely wrong about this.

However, this seems to me that it’s either a problem with Chromium, in which case I would recommend a reinstall and a completely new profile, or it’s hardware, but seeing as it works in Firefox, I think it’s safe to rule out that possibility.

I hope this helps.

Tried with a new profile with chromium and google without extensions (except for h264fy) and the issue is still there.

4

Have you followed these instructions?

5

Yes. I followed these instructions and vaapi works fine. I have used hardware decoding in chromium for years. The only issue is with paused videos in chromium which started after they introduced –enable-accelerated-video-decode flag.

I have this issue too. Have you solved it?

7

After reading wiki again, I solved it by switching from ANGLE driver to system driver, just adding flag “–use-gl=desktop”.
