How to choose the decode engine (d3d9 or d3d11) in WebCodecs ？

[yangfangfang1204]

when i decode the video by webcodecs , could i choose the decode engine(d3d9 or d3d11) ? I find we could decode the H264 video by webcodecs in win7, , only d3d9 is supported in win7. so i think webcodecs could adjust the d3d9 interface.

And there is a question： In Integrated GPU in win10, the decoding performance of d3d11 is much worse than that d3d9 !!! so could i configure the decoding engine（d3d9 or d3d11） in webcodecs ? if so , In Integrated GPU, the webcodecs decoding performance will get a promotion .

[dalecurtis]

There's no way to select d3d9 or d3d11 and we likely remove the d3d9 path in 2023.

Please file Chromium bugs at https://crbug.com/new with your chrome://gpu details.

[yangfangfang1204]

Is there any plan to improve the performance of d3d11 in Integrated GPU ?

[dalecurtis]

If you file a bug with your chrome://gpu details we can see if there's something we can do. Usually this means one of the drivers isn't recent.
