It supports an AES encrypted file or network stream, you can play Youtube URLs with it directly in addition to H265 and VP9 video playback. You can play up to 8 videos at the same time with this component which is pretty impressive. In addition to the different codecs supported you can also play a video from a memory stream, from an HTTP request, RTMP request, and more.

It supports 5.1 surround sound playback on Windows if the system supports it and there are over 50 different audio filters you can use with it.
