[BUG] Incorrect range signalling

[Selur]

ARGH,.... the whole start seems useless,..

For the frist encoding Hybrid used:

in both cases the calls Hybrid uses look correct and ffmpeg reports that pc scale is used.


Looking at the muxing call in the log:

"C:\Program Files\Hybrid\64bit\mkvmerge.exe" --ui-language en -o "I:\2025-03-05@19_38_54_7310__07.mkv" --global-tags "I:\TEMP\mkvtags_2025-03-05@19_38_54_7310__07.xml" --default-track 0:yes --color-matrix-coefficients 0:1 --color-range 0:1 --color-transfer-characteristics 0:1 --color-primaries 0:1 --default-duration "0:50/1fps" --aspect-ratio-factor 0:1/1 --no-chapters --compression -1:none --forced-track 0:yes --field-order 0:0 --no-audio --no-subtitles "I:\TEMP\tapeC_2_1_2025-03-05@19_38_54_7310_05.mkv" --track-name 0:"Track1" --default-track 0:yes --forced-track 0:no -a 0 --compression -1:none --no-video --no-subtitles --no-chapters "I:\TEMP\iId_17_aid_0_2025-03-05@19_38_54_7310_02.flac" --track-order 0:1,1:2

"--color-range 0:1" is wrong!
see: https://mkvtoolnix.download/doc/mkvmerge...olor_range
it should be 2.

=> I'll create a version which will output more debug output during the creation of the muxing call, maybe that will help to find the problem.
