When muxing an .M4V with a built in picture, it just does...nothing
I have stumbled over an .M4V file, with multiple languages and subtitles inside. Wanting to remove the languages which I don't need, I deselect the unneeded languages and click "start multiplexing". It quickly does...nothing. All other files work as intended.
--- Output of job 'Multiplexing to file "test.mkv" in directory "E:\test"' started on 2018-01-22 21:05:42 ---
mkvmerge v20.0.0 ('I Am The Sun') 64-bit
'Z:\test.m4v': Using the demultiplexer for the format 'QuickTime/MP4'.
And...that's it. Nothing more in the log.
