H.264 vs VP6

Build your own iPTV profitable network NOW!

Lately I was doing research about codecs and wanted to make a comparison between H.264 and VP6. There are a lot of discussions where people are a bit confusing about what shall they use to do live streaming with the best video quality for their viewers.

In general, VP6 and VP7 are designed to combine video quality with platform efficiency. If quality is an issue and you want to ensure that the largest number of PC users – including users having older, not so powered computers – can playback high-quality content (not HD), then the solution here is VP6. On2 VP6 can provide a higher visual quality, especially when using lower bit rates (you can push it to full SD). But take note that it will not run as well on certain older system configurations as I mentioned above.

VP6 is the preferred video compression format for use with Flash Player 8 and higher.

Flash Player 9 Update 3, released in 2007 includes support for the new Flash Video file format F4V and H.264 video standard (also known as MPEG-4 part 10, or AVC) which is even demands way much hardware resources but offers significantly better quality/bitrate ratio. (Now we can talk about true HD) Specifically, Flash Player now supports video compressed in H.264 (MPEG-4 Part 10), audio compressed using AAC (MPEG-4 Part 3), the F4V, MP4 (MPEG-4 Part 14).

The H.264/AVC video codec was created as a standard capable of providing good video quality at substantially lower bit rates (the idea was to reduce the bitrate with even more than half less compared to MPEG2 or MPEG-4 Part 2). An additional goal was to provide enough flexibility to allow the standard to be applied to a wide variety of applications on a wide variety of networks and systems. And here I am talking about being able to use it on low and high bit rates, low and high resolution video especially in the broadcasting field. Actually this revolutionary concept gave us the idea of creating a professional broadcaster being able to stream HD. We announced this in a press release found at http://www.tikilive.org/pdf/HDBroadcasterPressRelease.pdf

The TikiLIVE software delivers superior quality streaming while using the latest multicore technologies.We are able to deliver the highest encoded definition without the need for complex proprietary software.

In our previous projects we had questions about the ON2 technology and if that is suitable for HD streaming. Some people say it is but they don’t know ON2 is an old codec used a few good months ago to push SD to the limit. Well we really are able to stream HD as we discovered the way to do it with our application. The TikiLIVE broadcaster allows you to stream real HD and also record (then save the video file as a VOD).

You can check a few real samples to see the results here:
