Based on the log provided, your OBS Studio is failing because the Intel QuickSync (QSV) video encoder is crashing when trying to start the recording.

Here is the specific error from your log at timestamp 16:03:30:

[qsv encoder: 'msdk_impl'] Unsupported configurations, parameters, or features (MFX_ERR_UNSUPPORTED)

This indicates that the specific settings OBS is trying to use for the Intel Hardware Encoder are not accepted by your current graphics driver.

1. The Core Issue

You are using an 11th Gen Intel i7 (Tiger Lake) on Ubuntu 22.04. You have selected the Hardware (QSV, H.264) encoder.

When OBS initializes this encoder, it attempts to use the "High" profile with specific rate controls (ICQ). Your driver is rejecting this configuration (MFX_ERR_UNSUPPORTED), likely due to a driver incompatibility or a limitation in the Linux implementation of QSV.

2. Recommended Fixes

Solution A: Switch to VAAPI (Recommended for Linux)

On Linux, VAAPI is the native and most stable API for Intel graphics, whereas QSV is often a wrapper that can be buggy. Your log confirms your system supports VAAPI: FFmpeg VAAPI H264 encoding supported.

  1. Go to Settings > Output.
  2. Change Output Mode from Simple to Advanced (if needed to see the options).
  3. Look for the Video Encoder dropdown.
  4. Change it from QuickSync H.264 (or QSV) to FFmpeg VAAPI (H.264).
  5. Try recording again.

Solution B: Switch to Software Encoding (x264)

If VAAPI fails, your CPU is powerful enough (i7-1185G7) to handle software encoding for standard recording tasks.

  1. Go to Settings > Output.
  2. Change Video Encoder to x264.
  3. This uses your CPU instead of the GPU. It ensures stability but uses more processor power.

3. Other Observations

  • Safe Mode: You launched in Safe Mode because of a previous "unclean shutdown." Once you fix the encoder setting, you should restart OBS normally to restore your third-party plugins (if you use any).
  • Wayland: You are running on Wayland (Session Type: wayland). OBS is correctly using the PipeWire capture method (Screen Capture (PipeWire)), which is good. The failure is strictly related to saving the video (encoding), not capturing the screen.

Next Step: Would you like me to suggest specific bitrate or quality settings for the VAAPI encoder to get the best quality on your laptop?
