Is there an update from the devs about this issue?
Sorry for the delay. I’ve confirmed that AV1 is not supported with direct streaming. It just doesn’t work with the player right now so it’s disabled. If this changes in the future, we can enable it.
Thanks for replying.
Can you elaborate a little? is there a problem within FFmpeg, HLS…?
I’m only asking because maybe we (plex users) may help report this issue upstream.
I read a couple of weeks ago that the next FFmpeg version soon to be released will have a lot of AV1 improvements.
Please, let us know.
Sorry, I don’t know the details.
With the release of Android Plex 9.19.0, has there been any update in development with this?
I just ran into the issue last night that I have AV1 video and Opus 5.1 audio. My TV plays AV1 fine, and I have seen audio only transcoding in the past, so I expected Opus to be transcoded to ac3 while not touching the Video. But no matter what I do, AV1 is being transcoded to H264.
So in 9.20, this is not fixed 
Is Plex unable to generate “posters” for AV1 videos? (Not sure if they’re called posters, previews, frame captures, thumbnails, or something else.) All of mine still just have a blank black box, or grey box with file title. (Just added a new AV1 video and it got a proper poster for first time. Trying to figure out why.) Refreshing metadata did not help.
Update: Plex DOES now analyze AV1 properly, which is why that new video had a proper poster. Just need to go back to any of old AV1 videos and hit “Analyze”. Neat.
VP9 hardware decoding is available on Nvidia Shield and works as a charm with Plex. Not AV1.
But AV1 direct plays on my Android TV directly (a TCL TV) in Plex. Even 4k HLG content at 60fps.
However, it doesn’t direct play on the web browser, even on a machine with native AV1 decoding (Intel i9 series 12 with Chrome).
AV1 videos in YouTube direct play fine on the same machine.
VP9 videos direct play in Plex web as well, so I suspect it’s just a matter of enabling/allowing direct play of AV1 content on compatible machines?
Great job overall to the Plex team for the improved support of AV1!
Just confirming that with (as of today) current Andoid TV Plex and Plex Media Server, it still happens on my Sony KD-65XH9299 and my Sony HT-ZF9 that:
- AV1 + Opus Stereo direct plays
- AV1 + Opus 5.1 leads to conversion of Audio to eAC3 AND VIDEO to h264
This is absolutely unnecessary. Why is the video transcoded if the device is capable of direct playing it?
Seems new iPhone 15 supports AV1 hw decoding now. What does that mean for AV1 support on Apple devices? I assume they could add native support and on apple devices it would leverage hardware and on others it would use software decoding? Any ETA on this support? Would love to switch to AV1 for everything but looking for broader support before making the switch…
Finally bought a Roku Ultra for AV1 support (with UHD, Dolby Vision/Atmos). It seems to work just good enough for most AV1 (MKV) files, but there are a few problems. Still figuring things out…
First, it will play exactly nothing AV1 when Direct Play is set to Auto (must set to Forced). However, when Forced it will error if audio is 7.1 OPUS or AAC (video plays, no audio plays, Forced prevents audio transcode, and strangely will auto select any other audio if available, like any 5.1 or commentary tracks, even as Dashboard reports it’s playing other track).
Update: It seems Plex has fixed a few things. Roku now plays AV1 fine with DP auto, just gives a little popup that says things might not work properly… but it plays! Hooray for this.
Hi,
I have a issue with AV1 playback on a Fire Cube 3rd. The video load for about 30 sec and display “Unable to play the media”.
On Kodi with Plex addon, the playback work fine.
Regards
