Once Adobe added H.264 support to Flash, the computer browser market shifted almost immediately to H.264. The streaming market was much simpler when H.264 first launched, with computers comprising the dominating platform for streaming video and one plug-in, Adobe Flash, the dominant video player for most websites. Because H.264 is a standard, all video encoded by any H.264 codec should play on any H.264 decoder or player, whether in a browser, smartphone, or Smart TV. Intel and NVIDIA both offer hardware-accelerated H.264 codecs that can be accessed from the Wowza Streaming Engine. H.264 first launched in May 2003 as the successor to MPEG-2, primarily for use in broadcast applications as the internet was nascent.Īs a video standard, there are multiple implementations of the H.264 codec, including the x264 codec in FFmpeg, and the Beamr codec used in the Wowza Streaming Engine. Technically, AVC is defined in Part 10 of the MPEG-4 standard, and is different from the MPEG-4 codec, which was defined in Part 2 and never really got traction in the marketplace. H.264 and AVC refer to the same technology and are used interchangeably. It was created by two standards bodies, the ITU-T Video Coding Experts Group, which called the standard H.264, and the ISO/IEC JTC1 Moving Picture Experts Group (MPEG), which called the standard Advanced Video Coding (AVC). H.264 is a video coding standard or codec. We’ll conclude with a section on what you need to know to effectively deploy the H.264 codec, particularly within the Wowza Streaming Engine software and the Wowza Streaming Cloud service. This article provides a quick overview of the H.264 codec: what it is, how it performs, what it costs, and what it’s good for.
