HTML5 video
Support for HTML5 video has been steadily increasing. In June 2013, Netflix added support for HTML5 video. In January 2015, YouTube switched to using HTML5 video instead of Flash by default. In December 2015, Facebook switched from Flash to HTML5 for all video content.
Hauppauge MediaMVP
The MediaMVP supports the MPEG (MPEG-1 and MPEG-2) video format (and "only" that format). However, depending on the MediaMVP host software running on the host computer, the host software may be able to seamlessly transcode other video file formats before sending them to the MediaMVP in the MPEG format. The maximum un-transcoded playable video size is SDTV (480i). HDTV mpeg streams (e.g. 720p) need to be transcoded in real-time on the computer to SD format. Note: transcoding video can tax some slower computers.
