Support pixelcrop values in Matroska
It appears that VLC (version 3.0.4 on OSX was tested) ignores pixelcrop values. An examples can be downloaded here and I will try to attach. https://archive.org/details/10sec
This video file was created with ffmpeg v4.0.2 using:
$ ffmpeg -f lavfi -i testsrc=size=720x576 -t 10 -pix_fmt yuv420p 10sec.mkv
PixelCrop values were then added using mkvpropedit:
$ mkvpropedit --edit track:v1 --set pixel-crop-left=100 --set pixel-crop-right=234 10sec.mkv
which produces these values via mediainfo:
Width : 386 pixels
Original width : 720 pixels
Height : 576 pixels
but no crop is present in vlc 3.0.4 on oSX.
