Investigate the use of PNGCRUSH to reduce jukebox size

[Omertron]

Original issue 931 created by Omertron on 2009-08-13T17:34:14.000Z:

Utilise PNGCRUSH to reduce the size of the jukebox and possibly the impact
on the media player

Could use it in the same fashion as MediaInfo, i.e. it's not critical that
it is there or not.

See: https://pmt.sourceforge.net/pngcrush/

This was a personal itch, so I tried to implement it. This is my first time with the code, so it might be a little rough. But, using it will reduce PNG sizes by 10-30%. It has a noticeable (to me... placebo possible) impact on the speed of my jukebox.

Without pngcrush:
-rw-r--r-- 1 stan stan 715K Nov 8 20:03 movie_large.png
-rw-r--r-- 1 stan stan 131K Nov 8 20:03 movie_small.png

With pngcrush:
-rw-r--r-- 1 stan stan 509K Nov 8 20:03 Fight.Club_large.png
-rw-r--r-- 1 stan stan 96K Nov 8 20:03 Fight.Club_small.png

This adds two configuration parameters:
pngcrush.enable -> default false
pngcrush.home -> default ./pngcrush

This will add time to the jukebox generation. On my 5-year-old machine, it will add around 2 seconds per PNG file.

Nice! Thanks for taking the time to do this, I'll look to adding it to the code

Any updates on this?

Although the submitted code was good, it was another dependency to install and the overall benefits weren't that great. I was looking for a native java class that could do the same thing but haven't found one yet
