AV1 Browser Firefox

[frk1337 4]

Hello,

recently I discovered Emby now natively plays AV1 media in the Chrome browser when using the web app. However, the same file is not compatible with firefox (newest stable version available).

Jellyfin has no problem direct playing the same file in Chrome and Firefox.

Kind regards

Is your media file using MKV as the container?

Firefox doesn't support media playback which uses mkv as the container but chromium-based browsers does.

Since mkv isn't supported by Firefox, Emby will transcode the whole file including both audio and video. (if It have AV1 as the video codec.)

The reason on why Jellyfin has no problem It's because they remux the mkv file to webm then serve the webm directly with the extracted subtitles separably.

Yes, the files are mkv. Since webm is a subset of mkv this should come at a minimal cost and should be implemented soon?

Firefox does not support the mkv container.

Is transfering to webm like jellyfin does planned for Emby?

[Luke 40087]

I'd prefer to explore better options such as demuxing the mkv directly in the browser.

Is there any news on this?

Jellyfin remux the file and send as a webm container.

We'll start using AV1 with HLS segmentation, which means you'll be seeing more stream copying and less full transcoding. Thanks.
