VP10 Development Information; Specs?

[John C. Westmoreland, P.E.]

Hello All,

Where is the best place to get information on VP10?

Are there any specs available anywhere?

Thanks In Advance,

John Westmoreland

At the moment there is no specification anywhere, since the project only got started recently and is ever-changing. You may checkout libvpx from source (http://www.webmproject.org/code/), and view the experimental branch.

nextgen branch.   :)

What about the vp9 specification while at it? Would be extremely useful
to have it while trying to fix or extend independent implementations.

There are two branches that you may check out for VP10 currently.

The first is the playground branch - which is meant to host preliminary experimental tools. The second is the nextgen branch, which will host more stable tools either adopted from the playground branch or new.

For each branch, configure with --enable-experimental along with separate enabling options for various new tools being worked on.

Currently for the playground branch, you can try configuring with any combination of these options in bold:

--enable-experimental --enable-supertx --enable-copy-coding --enable-ext-tx --enable-filterintra --enable-interintra --enable-masked_interintra --enable-masked_interinter

You will get about 4% gain over baseline VP9. There was an ICIP talk recently which talks briefly about these tools, which should be available online sometime. 

Currently for the nextgen branch the available tools are:

--enable-experimental --enable-ext-tx --enable-tx64x64 --enable-filterintra --enable-txskip

where ext-tx is a better version of the tool in the playground branch, and txskip is only used in lossless mode. The stable tools from the playground branch are in the process of being promoted to nextgen currently.

Thanks for the replies everyone.

So, there isn't even a spec for VP9?

Would be interesting to see what the plans are for VP10 vs. HEVC.

Thanks!

Another comment - if that is OK.

So, when you peruse the web for this - you find claims that VP10 will be ready for release 'early 2015' - from this thread - that seems unlikely.

Any comments on that?

Thanks!

That's a good point. It's hard to fair  compare hevc vs vp9 because of although there are so many almost the same tools in vp9 as in hevc, some elements are done in essentially different way. W/o good spec the only way is to analyze the code....or play with config files. Even in this case I would say its hard to clear understand how complex algorithms are in vp9 in terms of memory bandwidth,  complexity,  parallelism....
But anyways seeing extra gains over vp9 or hevc would be interesting,  so plans (if any) and specs for vp10 are really good stuff.

[Debargha Mukherjee]

The 2015 timeline for VP10 was misquoted. 

A more realistic timeline is ~3 years, but also subject to the technical uncertainty of being able to achieve a substantial compression gain over VP9 at reasonable complexity.

Thanks.

Hi All,

Any update regarding VP10 progress? Currently, what are the tools supported in the nextgen branch?

Thank you!
