How to combine with ready-made camera library ?

Hello Pedro, I discovered this camera filter library along with your rtmp publish package. May I know the step to combine these two to work together ?

Thank you.

Hello,

Maybe you can try this way:
pedroSG94/RTSP-Server#110

You can create your own VideoSource using that library. You will need study that library to check the way to render a SurfaceTexture

I spent some time looking at the library and found this callback function for rendering the surface texture. May I know what is the next step ?
Also, the texture view that is created from the filter library is already set up with EGL. Is there any way to pass the texture view straight into your library so that it can be sent to the rtmp server ?

Now, you need create your own VideoSource as described in the issue I shared you.
You have a code example using cameraX library here:
https://github.com/pedroSG94/RootEncoder/blob/master/app/src/main/java/com/pedro/streamer/rotation/CameraXSource.kt

Also, the texture view that is created from the filter library is already set up with EGL. Is there any way to pass the texture view straight into your library so that it can be sent to the rtmp server ?

I provide you the SurfaceTexture to render in the start method of VideoSource that you need implement.
Use the reverse way (set a SurfaceTexture to my library) has no sense because you can't listen and get video data from a SurfaceTexture if it is not created by your own Gl context (this is the way OpenGl works). So the way is:

You have a library that need video data to work (RootEncoder) and a library that generate video data (camera1, camera2, camerax, MediaPlayer, CainCamera, etc)
The idea is that my library create a SurfaceTexture to obtain video data needed from the library that can generate it. So the library that generate video data, need render the SurfaceTexture to work.

Hello Pedro. I spend the last few days understanding the library and try to create the video source as you mentioned. The problem I am facing right is only audio packet is being sent while the log related to VideoEncoder being prepared and started can be seen in the logcat . May I know what could be the possible reasons for video packet not being sent ?

Hello,

Maybe the problem is that you are not rendering the SurfaceTexture provided by VideoSource correctly.
Video packets are generated each time SurfaceTexture is renderer with a new frame.
A way to test it is use startPreview method with a normal SurfaceView or TextureView and then the video should be renderer in that view

Can you show me your VideoSource code? Maybe I can help you more this way
