the result that I still got 16 bit FLAC was as I had installed the mmffmpeg over my system's ffmpeg and I suspect this was the problem. So I made a fine Arch package and installed it into /opt and wrote
into the FFMPEG location field in MakeMKV. When I run this in a terminal it works. But in MakeMKV the program freezes at conversion and even
/usr/lib/ld-2.16.so --library-path /opt/mmffmpeg/lib /opt/mmffmpeg/bin/ffmpeg
doesn't work. Then I tried to put this into a wrapper:
[command 1 / command 2]
made it executable and set the FMPEG location to /home/username/.MakeMKV/mmffmpegwrapper.sh but MakeMKV still freezes at conversation.
I didn't applied the mmffmpeg patch from http://www.makemkv.com/download/ffmpeg/
because it is already integrated in the main archive. I think so.
So, now I can't use mmffmpeg although it is installed. :/EDIT
: Oh, a friend told me, I need to set $@
at the end of the line, so
LD_LIBRARY_PATH=/opt/mmffmpeg/lib /opt/mmffmpeg/bin/ffmpeg $@
The wrapper is necessary, but it works now and I get 24 bit FLACs, yeah!
