Anyone able to run scrcpy with Boox?

I'm trying to run scrcpy with my Boox Leaf 3C but getting errors.
Below is the log:-

Does anyone know which video encoders are present in Boox if any?

Looks like Boox has removed video encoders?
Can anyone check if you have video encoders in ur boox devices?

Installed with latest update, no video encoders in NoteAir2P either.

It sounds more like that is some security motivated action from Google.
I can't imagine Onyx actually caring about encoders.

well, it doesnt impact non Boox devices it works on smart phones. I could be scrcpy issue. the way they changed the code. i was reading on scrcpy github, some older versions did work with Boox devices.
I saw on the release page, apparently, the code was changed post Android 13 to support it, maybe thats the issue and also support for newer video codec and it only looks for them.

well, Boox Leaf3C has video codec. Below is listing:-

Newer version of scrcpy doesnt support any of video codecs in Boox Leaf 3c:-

Well, if you only want to grab a screen you can use my AdbGrab.exe either interactively or not.
