Installing GPAC required for Youtube?

MPEG-DASH streams
YouTube Web site started using MPEG-DASH streams instead of flash (.flv) files. In order to convert the MPEG-DASH streams into a valid .mp4 file that can be played with any media player, you have to download and install the following open source software package: GPAC.

After you install this software, VideoCacheView automatically detect it and uses MP4Box installed as a part of GPAC package to convert the MPEG-DASH streams into a valid mp4.
If from some reason VideoCacheView fails to detect the installation of GPAC package , simply copy VideoCacheView.exe into the installtion folder of GPAC and run it from there.

If you don't install the GPAC package, you'll get 2 stream files (One for video and one for audio): mpegdashtmp1.mp4 and mpegdashtmp2.mp4
These files can be played by the media player of Windows 8. Be aware that this feature doesn't work with Chrome Web browser, simply because Chrome stores the cache entries of YouTube as empty URLs, and thus VideoCacheView cannot detect them...
