Recommended Posts

SVT-AV1 is out and i was interested to test how it compares, but as soon as i tried to playback AV1 video files with Emby there was problem in Web App playback "Video codec not supported" resulting in transcoded video stream instead.

I thought Emby and Chrome supported AV1 decoding. Is this not the case ?

OS: Win10 21H2 Update

Browser: Chromium  101.0.4951.41

Emby Version: emby-server-4.6.7

Emby does support AV1 playback on almost every device.

Since you're on Windows with Chromium, did you download the AV1 Video Extension over the Microsoft Store? Without It you won't be able to play AV1 videos on any (chromium) browser.

You can find It here: https://www.microsoft.com/en-us/p/av1-video-extension/9mvzqvxjbq9v?SilentAuth=1&wa=wsignin1.0&activetab=pivot:overviewtab

Yeah Emby Android App Direct Played the AV1 video.. kinda.. frame by frame.

I just installed the AV1 Extension but no change with the Web App. Youtube and PotPlayer plays AV1 videos just fine even without the Extension.

Still thanks for the help.

The Android App uses Exoplayer, which is horrible for AV1 playback.

If you enable the external player and use VLC you will be able to play those AV1 videos with a considerable low battery usage for a software decoder. (On real-time,  1080p 24-30fps ~5 Mbit/s Bitrate.)

On the Chromium issue, can you fetch the Emby logs to see what's the actual reason on why It's transcoding?

Even if the browser supports AV1, if Emby have to transcode either the audio or subtitle the video will also be transcoded. (Even changing audio tracks will make Emby transcode the video.)

I installed Jellyfin and it Direct Plays the AV1 files so problem solved i guess.

Hi, for us it is resolved in the upcoming 4.7 server release. You can also use our hosted web app now with your 4.6.7 server:

Thank you!

After using Jellyfin for couple hours i started to notice how janky it is and made me appreciate all the work that has been put into Emby 👍
