RtmpCamera2 seems to have a critical memory leak issue.

[JokerIce]

In your demo, both the SurfaceModeRtmpActivity and TextureModeRtmpActivity use RtmpCamera2. Additionally, I have attempted to use RtmpCamera2 in both RtmpActivity and OpenGLRtmpActivity. Upon entering the Activity, without recording any video or live streaming, and then directly exiting the Activity, a memory leak error is triggered.
By adding debugImplementation 'com.squareup.leakcanary:leakcanary-android:2.10' to your project, you can observe the log details of the memory leak issue.
