Reproduction Steps
--no-config : does not help :)
--no-terminal : everything is OK.
Expected Behavior
about 1% of 1 CORE/THREAD.
Imagine I was on 19200 terminal.
Actual Behavior
about 15% of 1 CORE/THREAD, because of CRAZY refresh rate of the terminal.
Log File
not GPU related. CPU Usage is from terminal emulator.
Sample Files
No response
I carefully read all instruction and confirm that I did the following:
- I tested with the latest mpv version to validate that the issue is not already fixed.
- I provided all required information including system and mpv version.
- I produced the log file with the exact same set of files, parameters, and conditions used in "Reproduction Steps", with the addition of
--log-file=output.txt. - I produced the log file while the behaviors described in "Actual Behavior" were actively observed.
- I attached the full, untruncated log file.
- I attached the backtrace in the case of a crash.
