Description
Hi FFmpeg team,
I am using ffmpeg with WebAssembly and it works nicely in a web browser.
I would like to request an enhancement, if this is the right place, to integrate ffmpeg and https://developer.mozilla.org/en-US/docs/Web/API/WebCodecs_API via -vcodec -acodec parameters. I can imagine this could improve encoding performance significantly.

This feature could benefit all the software currently using ffmpeg to decode videos with the hwaccel features. Similarly to what ffmpeg does with MediaCodec for Android, VAAPI, VDPAU, or DXVA2, ffmpeg could add support for WebCodecs making it very easy to port those applications to WebAssembly.

I want to look at this feature, but I don't have a clear plan yet.

I consulted with some web developers, and they expressed skepticism about the practicality of adding webcodecs in FFmpeg. They suggested directly invoking webcodecs without going through FFmpeg's encapsulation. Therefore, I'm closing the issue.

Could you elaborate on the potential pitfalls you have found with this? I have been doing some video manipulation in the browser and the more I dig deeper the more I wish I could utilise FFmpeg more, so I have been considering exploring this approach. Your input here could save me a ton of time.

I think this is very similar to the MediaCodec support for Android, you could for sure do it by yourself using JNI, but the ffmpeg layer make this much easier and portable. I hope WebCodecs supoort could be included in ffmpeg some day.

It's not the same compared to MediaCodec. MediaCodec has C API, and supported by FFmpeg, and JNI is well defined too.
This seems very unlikely to me.
