Wowza ClearCaster Streams 1080p to Facebook Live

Wowza ClearCaster is a $6,000 encoder from Wowza, that at first glance may cause you to repeat the company’s name loudly, as in, “Wowza, that’s a high price for a single channel streaming appliance.” Perhaps so, but it’s the only encoder that can stream 1080p to Facebook Live, and as I learned when I reviewed the product, it has great …

In Case You Haven’t Heard: Apple Joins Alliance for Open Media

The skinny: Apple, a member of the MPEG LA H.264 and HEVC patent pools, and staunch supporter of standards (and avoider of open source-codecs) broke ranks and joined the Alliance for Open Media.
