Log File

.

Sample Files

.

I carefully read all instruction and confirm that I did the following:

• I tested and confirmed that the issue exists with the latest release version or newer.
• 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.

Start by reproducing the issue with portable_config/mpv.conf and portable_config/input.conf on the working and failing Blu-ray images, then compare Working.txt with No Working.txt. Done means the Transformers disc enters and displays its menu correctly while the existing disc-navigation bindings continue to work.
