NVENC settings show "CQ Level" option while setting CQP

Open Bleuzen opened this issue 4 months ago • 2 comments

Operating System Info

Linux, but probably also others

OBS Studio Version

Git

OBS Studio Version (Other)

also applied https://github.com/obsproject/obs-studio/pull/10133

Expected Behavior

The UI should show "CQP" when setting the CQP level

Current Behavior

The UI does show "CQ Level": image

...while in CQP mode. As far as I'm aware, OBS does not support CQ mode with NVENC currently so the label of the option does not make sense

Steps to Reproduce

  1. Open Settings
  2. Click on Output tab
  3. Choose advanced output mode
  4. Choose a NVENC encoder
  5. Choose Rate Control: CQP
  6. Have a look at the settings, see "CQ Level" option

Seems like the solution here is to just change CQ Level to QP Level. Feel free to open a PR.

As for why we're doing the mapping the way we are, we're following the standard set by the reference AV1 encoders to keep things more or less consistent.

quick note: AOM AV1 is also affected, showing "CQ Level" in "CQP" mode, while actually using CRF
