FWIW, the getUserMedia() portion of such a setup remains the same, so you don't lose AEC or anything else coupled there.

Ah, I didn't realize that always happened. I thought it was only if you did something that might have OS specific rendering characteristics (text-draws, etc). Maybe having an Image…

FWIW, you can do this with a few lines of JS in the browser using canvas.drawImage() from an img element followed by canvas.toBlob().

Thanks for writing this! It skips my favorite edgy product name though, the X-Fi Fatal1ty cards: https://en.wikipedia.org/wiki/Sound_Blaster_X-Fi :)

If only that were true, battery usage would be much better :) Just consider the prominence of content like tiktoks/shorts/reels/etc alone.

Unfortunately canvas (rgb'ish) can't overlay as efficiently as (yuv'ish), so there is some power cost relative to the lowest power video overlays. It really only matters in long fo…

Chrome supports HEVC with transparency on macOS since VideoToolbox does. Other platform decoders don't support it though.

What a fun excursion :) You can also use the ImageDecoder API: https://developer.mozilla.org/en-US/docs/Web/API/ImageDecode... and VideoFrame.copyTo: https://developer.mozilla.org/…

I still remembered my id from all those years ago, 1569200. I was excited to read others were logging in with their old numbers, so I tried the password I thought I had used, but n…

IIRC, that bot used to be called bugdroid. I forget when it switched over, probably somewhere in 2020.

Very cool! I think it's missing some entries though. I'm pretty sure we've had at least one in third_party/ffmpeg. Those fixes often land upstream first which might make tracking d…

Even if you have crash reporting disabled there should be a .dmp generated somewhere in the user profile directory. Manually uploading that to a bug at https://crbug.com/new would …

Often Chrome doesn't know when more frames are needed either, so it's not something we could add an API for unfortunately. Yes, just feeding inputs 1 by 1 for each dequeue event un…

* Hmm, what kind of scheme are you thinking beyond per frame QP? Does an abstraction on top of QP work for the case you have in mind? * Reference frame control seems to be https://…

Please file an issue at https://crbug.com/new with the details and we can take a look. Are you rendering frames in order? Android may have some quirks due to legacy MediaCodec rest…

The amount of frames necessary is going to depend on the codec and bitstream parameters. If it's H264 or H265, there's some more discussion and links here: https://github.com/w3c/w…

Thanks for the nice write up! I work on the WebCodecs team at Chrome. I'm glad to hear it's mostly working for you. If you (or anyone else) has specific requests for new knobs rega…

We're starting to see a move towards this with HEIF / AVIF containers, however in cases where "every bit must be saved" the general purpose containers like ISO-BMFF introduce some …

It may just work in Firefox on OS with xHE-AAC support since they already rely on the system for AAC decoding IIRC. canPlayType/isTypeSupported probably indicate no support unless …

Chrome has supported xHE-AAC since 2020 on Android, 2022 on macOS, and added support on Windows last week.

It's a plug-in to the Windows ID3D11VideoProcessor API, https://source.chromium.org/chromium/chromium/src/+/main:ui/...

I think you can skip the transcode step entirely in favor of transmux with BMP too.

Chrome has something similar here: https://source.chromium.org/chromium/chromium/src/+/main:chr... We accept contributions from other sites (e.g., Vimeo, Dailymotion, etc) who want…
