Does Plex Support AV1?

What’s clear currently is that Plex hasn’t added support for AV1 codec, nor does it allow AV1 direct play on AV1-supported devices. The Plex support team does not say why the AV1 codec is not included and whether will Plex support AV1 in the future is still unknown. To play back AV1 content through Plex, the only way is to transcode AV1 to a codec format that Plex supports, such as HEVC and AVC. But by doing so, you will lose some video quality, even though it may not be noticeable to the eyes. If you can accept some quality loss, you can follow the next part to learn the steps to convert AV1 to a Plex-friendly format to stream the content without error.
