Support AV1 in mp4 - Githubissues

cromefire commented 4 years ago

Support detection of av1 in mp4 in firefox and chrome:

To probe support use:

video.canPlayType("video/mp4; codecs=av1");

cromefire commented 4 years ago

To try av1 in firefox (desktop), turn on "always prefer" here and then try this (ensure av1 is used in the stats for nerds)

We already do: #1167

cromefire commented 4 years ago

Okay but av1 in mp4 support is still missing. This would be video/mp4;Codecs=av1

cromefire commented 4 years ago

This is what YouTube for example does

Artiume commented 4 years ago

So av1 files can't be streamed in .ts containers. we have to use mp4 containers. I tried disabling video transcoding to verify it would work in the browser and it kept failing. Turns out it was trying to Direct Stream and ffmpeg ate itself.

Shush bot

Can we also add mkv containers? I know how to work with mkv and it's tools,etc. I must not be alone using mkv containers with av1? I tried streaming a mkv av1 50fps video in jellyfin and got a not supported error, quite sad.

It would feel weird having a bluray collection locally with a "webm" file format, or is it? I used mp4 "back in the days" when the video was x264 encoded but that is pretty much it. all my videos are mkv now.

heyhippari commented 4 years ago

MKV is unfortunately not supported by browsers.

Historically, MKV was treated as WebM (By Emby, then that behavior was inherited by Jellyfin). However, we removed that behavior because, while WebM is essentially a small subset of MKV, it's not fully compatible with MKV, and caused some errors when files weren't compatible.

@MrTimscampi Oh I see, thank you for the explanation. :heart: I guess it's easier in the backend to support webm only than trying to support both :disappointed:

It is a little off topic so feel free to redirect me if needed, but I'll get faster answer and probably a better one too asking this here and now: If I want my library to be as jellyfin-friendly possible while having the flexibility and audio quality I currently have, should I start using webm for my new encodes with opus/av1 instead DTS and stuff? I mean, opus rocks. :v:

x264 videos inside mkv should be pretty easy to "port", just need to transcode the audio track. Main issue is vodsub but I know there is plan to extract the images on the server and support them in browser or something so no biggy on that part. The sad thing is aas subtitles won't have the custom fonts because webm doesn't support attachments. Kodi and the mpv-shim can use those tho, but I understand the browser's limitation too.

EDIT: Ohhh I think mp4 does pretty much everything I want compared to webm and is supported in browser, so... woops.

So av1 files can't be streamed in .ts containers. we have to use mp4 containers

Same goes for FLAC. I can directstream AV1+FLAC to Firefox just fine if it's in MP4, but if it's in MKV it will be transcoded into H.264+AAC to be put into a TS container.
