Av1 library support

Channels DVR Server Feature Requests

AV1 with opus audio in an mkv container plays fine on my iPhone and AppleTV.

For me the only missing thing is generating thumbnails for videos that I have in channels-personal/videos. Currently all my AV1 videos have no thumbnail or the broken thumbnail icon, so it's not a great UX.

FWIW, anecdotally AV1 seems to suddenly be a lot more common on youtube. I've always downloaded with the --prefer-free-formats flag with yt-dlp, and have almost always gotten VP9. However in the last 2 months or so I've usually been getting AV1.

I find my Apple TV just does not have enough juice to play 2160p60 videos encoded with AV1. Tried recently to play with Emby on Apple TV(2nd Gen 2021 A2169) 11Mbps AV1 2160p60 video downloaded from youtube and it was a freeze frame. Youtube app plays vp9 version at 23Mbps of the same video.

My LG CX plays the same video AV1 2160p60 no issues in the youtube app.

Not seeing this. Are there errors in your log?

Quick question - where can the beta be downloaded from? I assume it has to be sideloaded? If so, unfortunately I probably can't test as I have it installed on an Echo Show 15 (which doesn't allow sideloading).

Thanks.

Unfortunately I am not seeing any error logs. For example here is all the logs I see for one AV1 video that is not displaying thumbnails:
