I'm not one to go negative, but when I saw that Microsoft was including HEVC in Windows 10, scheduled for release in 2015, I just had to laugh. Over two years after Windows 8 shipped, I still use it only when I absolutely have to. The most ardent rec...

Handout for Multiscreen Delivery Workshop

Here is the presentation handout for my Encoding for Multiscreen Delivery: H.264, Protocols and Devices, workshop today at Streaming Media West. Here's the description.

Learn how to create a set of video files that will play on all devices, from smartphones to computers and OTT devices. The workshop starts by exploring key concepts like protocol and container formats and technologies like HTTP Live streaming, DASH, and dynamic streaming. Then it moves to a technical overview of the H.264 specification to identify those configuration parameters that impact quality and those that don't, and how they affect playback compatibility. Then we'll review the technical requirements for single and multiple file delivery to Flash, HTML5, iOS, Android, Windows Phones, Windows 8, and the Apple TV, Roku, and other OTT devices. You'll walk way knowing the technical requirements for delivering to all key platforms and an understanding how to do so
