Expected Behavior

No warnings in the log file and initialize the encoder once.

Current Behavior

These warning log lines are generated

10:00:34.328: encoder 'advanced_video_stream': Cannot apply a new video_t object after the encoder has been initialized
10:00:34.328: encoder 'advanced_video_stream': Cannot set the scaled resolution after the encoder has been initialized
10:00:34.328: encoder 'advanced_video_stream': Cannot enable GPU scaling after the encoder has been initialized`

Steps to Reproduce

1. Have replay buffer and recording start when the stream starts
   
2. use the same encoder for recording and streaming
   
3. start streaming

Anything else we should know?

It looks like OBSBasic::StartStreaming calls AdvancedOutput::SetupOutputs twice, once via AdvancedOutput::SetupStreaming and once via AdvancedOutput::StartRecording

Start with OBSBasic::StartStreaming and trace the two AdvancedOutput::SetupOutputs calls described through SetupStreaming and StartRecording. Reproduce the shared stream-and-recording setup from the issue and compare the resulting log with the linked OBS log. Done means the encoder is initialized once and the three warnings no longer appear.
