java.lang.IllegalStateException: configure() is valid only at Initialized state; currently during configure()

The trace runs from StreamBase.stopStream (StreamBase.kt:252) into prepareEncoders (StreamBase.kt:575) and then VideoEncoder.prepareVideoEncoder (VideoEncoder.java:172), where MediaCodec.configure() is called while a configure is already in progress. Start by reading how stopStream and prepareEncoders manage encoder state, then reproduce with a quick stop during streaming. Done means stopping a stream no longer throws this exception, and the existing stream tests still pass.

Describe the bug

The application crashes with an IllegalStateException when attempting to stop a screen sharing stream. The error occurs because MediaCodec.configure() is called from an invalid state (during configure()) instead of the required Initialized state.

To Reproduce

Steps to reproduce the behavior:

1. Start screen sharing using ShareScreenService
2. Initiate stream stop procedure

if (genericStream.isStreaming) {
                    GlobalScope.launch(Dispatchers.Main) { // Or a custom scope
                        withContext(Dispatchers.IO) { // Perform blocking operation on IO dispatcher
                            genericStream.stopStream()
                        }
                    }
                }

3. Observe crash with the following stack trace

Expected behavior

The stream should stop cleanly without throwing an IllegalStateException.
