Raspberri Pi 4 Image loss of sync

[paolozXXII 2]

Hi, I'm playing with the latest image (3.0.21) for a Rasperry Pi 4 (4GB). Emby (client) starts windowed and works fine unless I do fullscreen or - still windowed - play 4k files. Mostly h265.

In full screen it heavily loses the lip-sync while 4k files shows a frame every second or so. Ethernet connected to the same switch as the Emby server.

In other distributions I've noticed is possible to set an amount of ram to allocate to graphic card, (via raspi-config) but I'm not able to find that command on your distribution... Maybe it will help?

I do confirm that Kodi on LibreELEC with the EmbyCon plugin|addon (don't ask how I manage to install it though) performs as expected.

Hi there, let's look at an example. Please attach the information requested in how to report a media playback issue. Thanks!

Hi steps are quite easy to reproduce. The community reports a lot of issues exactly like this.
Get a Rasperry pi 4 b, 4 GB of RAM. Download emby-theater_3.0.21_rpi4b.img.xz and burn it in t a SD Card big enough.
set the passwords, start Emby and connect it to your emby server. (log attached)

In the pre-set size window the playback's fine, before starting the video make the window full screen and you'll immediately hear an audio delay of seconds, along choppy video refresh.

Anyway, libreElec with kodi and EmbyCon add-on it shows no such behaviour.

Update. Did a reboot of the Pi, situation vastly improved in full-screen although I can't see overlays (the progress bar, subtitles choice, etc) not in the window when movie starts...
