Expected Behavior

Dynamic bitrate => it should adapt the bitrate to my connection.
In OBS 27.X it worked perfectly.

Current Behavior

Since I use the version 29 of OBS, when I use dynamic bitrate, the bitrate stop working after a certain time and the connection stop to work (OBS show 0 kb/sec with a green status)

Steps to Reproduce

1. Use dynamic bitrate
2. Start a stream
3. After a certain time, dynamic bitrate will stop to work and show 0 kb/sec

Anything else we should know?

It stopped to work here :
16:50:21.683: [rtmp stream: 'simple_stream'] bitrate decreased to: 3000
16:50:21.700: [qsv encoder: 'simple_video_stream'] Failed to reconfigure
16:50:25.724: [rtmp stream: 'simple_stream'] bitrate increased to: 3200, done
16:50:25.724: [rtmp stream: 'simple_stream'] going back to prev bitrate
16:50:25.724: [rtmp stream: 'simple_stream'] bitrate decreased to: 3000
16:50:25.733: [qsv encoder: 'simple_video_stream'] Failed to reconfigure
16:50:29.762: [rtmp stream: 'simple_stream'] bitrate increased to: 3200, done
16:50:32.480: [rtmp stream: 'simple_stream'] going back to prev bitrate
16:50:32.480: [rtmp stream: 'simple_stream'] bitrate decreased to: 3000
16:50:32.500: [qsv encoder: 'simple_video_stream'] Failed to reconfigure
16:50:36.497: [rtmp stream: 'simple_stream'] bitrate increased to: 3200, done
16:51:07.489: socket_thread_windows: Received FD_CLOSE, 30724 ms since last send (buffer: 0 / 430080)
16:51:07.489: socket_thread_windows: Aborting due to FD_CLOSE, error 0

Start by reviewing the linked OBS log and the dynamic bitrate sequence around the RTMP stream, QSV encoder reconfiguration failures, and Windows socket FD_CLOSE. Trace the dynamic bitrate and encoder reconfiguration entry points from those log messages. Done means dynamic bitrate continues adapting during a stream without reaching 0 kb/sec or losing the connection.
