Fixes versions of mkvinfo built with GUI support enabled by default

[hilts-vaughan]

Some versions of mkvinfo are shipped like this, especially some of the pre-built binaries on Windows. To get them to report their contents in console mode, this flag is required.

The bottom is just a clean up that was made to fix a bug in Strawberry Perl on Windows that I was used... it wasn't processing the inline-arguments properly. (Weird, huh?). Take it or leave it.

The other commits are remnants of my old fork. We can clean this up if you're OK merging this in.

Thanks for your time.

Hmm. When I try this with mkvinfo v9.1.0 on Mint it actually makes it fail rather then ignoring it.

$ mkvinfo a.mkv --no-gui Error: Only one input file is allowed.

Hm. Working on Windows;

mkvinfo.exe --version mkvinfo v9.1.0 ('Little Eathquakes') 64bit

lemme try my NIX* machine.

You're right; doesn't work on Arch Linux when running JUST the above command.. However, it runs with the script. Must be a # of parameters / ordering thing. Run it with the script instead of invoking manually mkvinfo. Seems to work fine over here.

The relevant commit is here:

2016-03-18 Moritz Bunkus moritz@bunkus.org mkvinfo: change: on Windows and Mac OS mkvinfo will now launch the GUI by default unless the option »–no-gui« (or »-G«) has been given. This is due to the fact that on both OS users often use portable versions respectively disk images and launch the executable directly and not via start menu entries. In those situations adding command line options for launching the GUI is unnecessarily difficult.

This will affect OS X as well.

Doesn't work via script either for me. What does just "mkvinfo --no-gui" output on a platform that supports it? Since it thinks that's a file where it doesn't I suppose we could just detect the behaviour early in the script.

As an aside I'll put in an issue to mkvtoolnix/bunkuz later today to see if he can't just add that option to all platforms, seems kind of silly not to.

[hilts-vaughan]

Working on Arch Linux; maybe something else unique.

For a platform that supports it, the output is the same as if it continued on normally on Linux without a GUI, or if you provide an invalid file:

(MKVInfo) Error: couldn't open input file a.mkv (open file error).

This is no longer required, they reverted the commit that made this the default on MKVToolnix 9.5+
