Server Version#: Version 1.26.0.5715
Player Version#: new chromecast with android tv, i can’t find the version but it’s updated

No server logs. Plex works fine with all of my firestick streaming sticks. We just got a new chromecast with android TV, which works fine with everything excet Plex. If you start a video, it works fine. If you pause, it will unpause just fine too. If you “skip intro”, skip 15 seconds ahead, use the seek bar, or the FF/RW arrows… it instantly screws up.

I have internal to the house streaming set to play original quality. I modified it for this streamer so that it plays at 1080p 8mb. Same thing. Try changing it down to something terrible like 720p 4mb, Same thing. HOWEVER, if I click to “play original quality” it flips back to playing at 1x speed and is fine.

I did some more experimenting,. I removed the transcode requirement for the chromecast and tested untranscoded streams. Same thing, they work until I fast forward or seek… but if I change it to transcode while it is doing this stupid 2x ff crap, it will go back to normal.

Something is broken in the handshake, or the player of the chromecast. Making it renegotiate the handshake seems to fix it. This is driving us nuts. When fix?
Here is relevant info from an affected video… but they all do it.

There’s a new demuxer that just got released two days ago, so version number of the client is very important. It’s also on a staged rollout, so some people may get the new demuxer immediately and some will have to wait a few days.

To find the version number, go into settings. It should display it at the bottom of the screen, but you may need to scroll down a little to read it.
