You work with an OVP the same way you work with a UGC site: you upload the file to the service; it encodes and supplies a player and embed code. Regarding the player, most vendors offer the ability to create a branded player with all the normal playback controls and embedding and email options, if desired. Another common feature is the ability to embed a single player in a page and create a video library for viewers to click through.

What is H.264?

H.264 is the most widely used codec on the planet, with significant penetration in optical disc, broadcast, and streaming video markets. However, many uses of H.264 are subject to royalties, something that should be considered prior to its adaption. Other factors to consider include comparative quality against other available technologies, like Google’s WebM, as well as the general availability of decoding capabilities on target platforms and devices. This article discusses H.264 and competitive technologies from these perspectives.

The Moving Picture: How Powerful a Notebook Do You Need for On-Location Editing and Streaming?

I shoot a lot of live events and have been streaming more and more of them live, streaming the events from one of my Core2Duo-based notebooks-a Hewlett-Packard 8741w and a MacBook Pro. I've used Telestream Wirecast for most events, but all have been single-stream, relatively low-resolution broadcasts, like 480x360 or smaller.

I'm starting to get requests for bigger-screen webcasts, and for multiple-bitrate adaptive streams to optimally serve a broad spectrum of viewers connecting from 3G to 50GB FiOS. Of course, everyone wants to send video to iOS devices these days, so that's typically next on the wish list.

What is a Codec?

Codecs are the oxygen of the streaming media market; no codecs, no streaming media. From shooting video to editing to encoding our streaming media files for delivery, codecs are involved every step of the way. Many video producers also touch the DVD-ROM and Blu-ray markets, as well as broadcast, and codecs play a role there as well. 

Though you probably know what a codec is, do you really know codecs? Certainly not as well as you will after reading this article. First we’ll cover the basics regarding how codecs work, then we’ll examine the different roles performed by various codecs. Next we’ll examine how H.264 became the most widely used video codec today, and finish with a quick discussion of audio codecs.
