Channel send performance issue

[distant trellis]

Hello , I am trying to build a plugin to be able to stream the content of your camera to the frontend.
While searching this topix I learned about webRTC and others methods but I felt like it was a bit overkill the use network tech to communicate with the same app. I then decided to try tauri's channels.

My issue is that I am experiencing verry low fps. While debuggin I found out that on the rust side on arround 55 ms of proccesing aroung 50ms were spent in channel.send().

I am doing something wrong in the way I use the channel ?

the rust code :

the typescript code :

does the send stop when the typescript callback is done ?

I'm guessing FrameEvent is serializable ? If yes, you can try to use raw bytes instead. The IPC can use serialized data or raw bytes
https://v2.tauri.app/develop/calling-rust/#returning-array-buffers

It should help a little, but the IPC is known to be slow, so do not expect very quick send

Yes nevermind I stop using it.
I wanted to use it for camera streaming but it was not a good idea.

Changed to webRTC anyway
