Expected Behavior

I expect that "Start Recording" works every time.

Current Behavior

"Start Recording" only works if the recording settings are not changed beforehand. If they are changed, OBS Studio must be closed and opened again before start recording will work.

Steps to Reproduce
  1. Run OBS-Studio.
  2. Set video encoder to "QuickSync HEVC" or "QuickSync H.264" (this can be done after starting OBS-Studio or saved from the previous session, it does not matter which one is done).
  3. Change a setting in the recording tab (eg: the bitrate value)
  4. Start recording and observe the "Starting the output failed. Please check the log for details" error
Anything else we should know?

Research direction

Start by reviewing the linked OBS Studio log and reproducing the failure on Ubuntu 24.04 with QuickSync HEVC or H.264 after changing a recording setting. Compare recording startup with unchanged settings and confirm that the fix allows Start Recording to work without restarting OBS Studio.
