    Google / Mozilla launch WebM project to bring open video to web 

    WebM is an open, royalty-free, media file format designed for the web.

    WebM defines the file container structure, video and audio formats. WebM files consist of video streams compressed with the VP8 video codec and audio streams compressed with the Vorbis audio codec. The WebM file structure is based on the Matroska container.

    Benefits of WebM

    *Openness and innovation. A key factor in the web’s success is that its core technologies such as HTML, HTTP, and TCP/IP are open for anyone to implement and improve. With video being core to the web experience, a high-quality, open video format choice is needed. WebM is 100% free, and open-sourced under a BSD-style license.
    *Optimized for the web. Serving video on the web is different from traditional broadcast and offline mediums. Existing video formats were designed to serve the needs of these mediums and do it very well. WebM is focused on addressing the unique needs of serving video on the web.
    o Low computational footprint to enable playback on any device, including low-power netbooks, handhelds, tablets, etc.
    o Simple container format
    o Highest quality real-time video delivery
    o Click and encode. Minimal codec profiles, sub-options; when possible, let the encoder make the tough choices.

      Some detailed analysis is on http://x264dev.multimedia.cx/?p=377

      Google’s choice of container and audio format for HTML5

      Google has chosen Matroska for their container format. This isn’t particularly surprising: Matroska is one of the most widely used “modern” container formats and is in many ways best-suited to the task. MP4 (aka ISOmedia) is probably a better-designed format, but is not very flexible; while in theory it can stick anything in a private stream, a standardization process is technically necessary to “officially” support any new video or audio formats. Patents are probably a non-issue; the MP4 patent pool was recently disbanded, largely because nobody used any of the features that were patented.

      Another advantage of Matroska is that it can be used for streaming video: while it isn’t typically, the spec allows it. Note that I do not mean progressive download (a’la Youtube), but rather actual streaming, where the encoder is working in real-time. The only way to do this with MP4 is by sending “segments” of video, a very hacky approach in which one is effectively sending a bunch of small MP4 files in sequence. This approach is used by Microsoft’s Silverlight “Smooth Streaming”. Not only is this an ugly hack, but it’s unsuitable for low-latency video. This kind of hack is unnecessary for Matroska. One possible problem is that since almost nobody currently uses Matroska for live streaming purposes, very few existing Matroska implementations support what is necessary to play streamed Matroska files.

      I’m not quite sure why Google chose to rebrand Matroska; “WebM” is a stupid name.

      The choice of Vorbis for audio is practically a no-brainer. Even ignoring the issue of patents, libvorbis is still the best general-purpose open source audio encoder. While AAC is generally better at very low bitrates, there aren’t any good open source AAC encoders: faac is worse than LAME and ffmpeg’s AAC encoder is even worse. Furthermore, faac is not free software; it contains code from the non-free reference encoder. Combined with the patent issue, nobody expected Google to pick anything else.

      Summary for the lazy

      VP8, as a spec, should be a bit better than H.264 Baseline Profile and VC-1. It’s not even close to competitive with H.264 Main or High Profile. If Google is willing to revise the spec, this can probably be improved.

      VP8, as an encoder, is somewhere between Xvid and Microsoft’s VC-1 in terms of visual quality. This can definitely be improved a lot, but not via conventional means.

      VP8, as a decoder, decodes even slower than ffmpeg’s H.264. This probably can’t be improved that much.

      With regard to patents, VP8 copies way too much from H.264 for anyone sane to be comfortable with it, no matter whose word is behind the claim of being patent-free.

      VP8 is definitely better compression-wise than Theora and Dirac, so if its claim to being patent-free does stand up, it’s an upgrade with regard to patent-free video formats.

      VP8 is not ready for prime-time; the spec is a pile of copy-pasted C code and the encoder’s interface is lacking in features and buggy. They aren’t even ready to finalize the bitstream format, let alone switch the world over to VP8.

      With the lack of a real spec, the VP8 software basically is the spec–and with the spec being “final”, any bugs are now set in stone. Such bugs have already been found and Google has rejected fixes

      Google made the right decision to pick Matroska and Vorbis for its HTML5 video proposal.

      Google Has A Problem: VP8 Is Not As Good As H.264

      “Based on test results from two different codec experts, Jan Ozer (test results link to come shortly) and Jason Garrett-Glaser (test results), they both came to the conclusions that the VP8 codec provides similar quality to H.264, but in most cases, H.264 is still better quality wise than VP8. Both also stated that most won’t notice the difference between VP8 and H.264, but that’s not what VP8 was suppose to be about. VP8 was touted as the video codec that was suppose to replace H.264 because it could offer better quality at half the bandwidth, something both reviewers said is not possible.”

    Flash vs html5 h.264 test results 

    As we know Steve Jobs and other Apple execs have recently condemned the Flash plugin as too CPU intensive for use in their products, instead suggesting everyone follow their lead in moving to h.264 playback in html5. Jan Ozer of the Streaming Learning Center has run some comparison tests as to which method uses the most cpu resources.

    Only Safari and Chrome currently support html5 h.264. First thing he found was that as far as Safari in Windows goes that support is imaginary as it doesn’t work.

    On Macs, however, Safari html5 showed marked superiority – 12.39% versus all the competition at 40-50%. On Windows Flash 10 had a slight lead but once he upgraded to Flash 10.1, which takes advantage of hardware acceleration, there were massive CPU savings – in chrome, for example, dropping the load to 6.3%.

    Ozer quotes Anand Lai Shimpi as saying that it’s up to Apple to expose the “hooks” that would allow Flash to exploit hardware acceleration in their products.

    He concludes:

    Apple complaining about Flash being a CPU Hog while not exposing “the appropriate hooks” to enable Adobe to access hardware acceleration seems disingenous at best. To be fair to Apple, though, the iPad related timing was unfortunate, with the bulk of the development work done under the shadow of Flash Player 10.0, which didnt offer hardware acceleration other than full screen on any platform and was clearly less efficient than the HTML5-based approach Apple adopted. Now that Adobe has proven the concept on Windows, perhaps Apple will cooperate with Adobe to make hardware acceleration on the Mac, iPad and future devices happen. If they choose not to, however, they should quit pointing fingers at Flash.

    What else? We also learned that not all HTML5 browsers/H.264 decoders are created equal. Significantly, with Flash 10.1 deployed, Googles HTML5 implementation required the most CPU horsepower of all playback scenarios — by far — on the Windows platform. On the Mac, Firefox and Safari with Flash required less CPU horsepower than Chromes HTML5 implementation.At least from a CPU utilization perspective, Flash isnt BAD and HTML5 isnt GOOD. It all depends upon the platform and implementation

      The new Zune browser is surprisingly good, but not as good as the iPod’s. It works well, but isn’t as fast as Safari, and has a clunkier interface. If you occasionally plan on using the web browser that’s not an issue, but if you’re planning to browse the web alot from your PMP then the iPod’s larger screen and better browser may be important.. I’m currently working on Fishbone Diagram project.
