Bricks are a new one to me, or is this just a slight variant on the tile technique?

There is a new article from BBC R&D

https://www.bbc.co.uk/rd/blog/2019-0...ssing-hevc-vvc

I can't find any reference but I assume they tested it with VTM 5.0.

Results looks, good especially for single pass and Streaming. I Still wish VVC will push further in bitrate reduction. For resolution I cared about, which is NOT 4K / UHD, I think the reduction was only 25%.

Nrr, another mean PSNR study, no subjective quality analysis. PNSR is the least well subjectively correlated metric we ever use.

Also, past studies have shown that libaom shows better PSNR but similar or slightly worse subjective quality than HEVC HM. A study that had PSNR and subjective data would let us see if AV1 is getting psychovisual improvements. The hope is libaom would be evolving to improve psychovisual quality even if it reduces PSNR.

I've converted it to PDF:

You can also get it from here.

So around 35% to 40% reduction.

Are there any similar test done for EVG?

New Viable Video Codecs on the Way? Maybe

VVC isn’t far enough along in its development to properly assess its practicality as a next-generation MPEG codec. One of its developers, Fraunhofer, says the technology has gained 30-35 percent improved efficiency over HEVC with an eventual target of 50 percent. A finalized standard is due sometime in 2020. On the licensing side, observers say VVC will not be free, but anything beyond this eventuality is pure guesswork.

There are some caveats cloud MPEG-5/EVC, however:
1.EVC will not deliver as much efficiency over HEVC as VVC promises.
2.What IP will be used and what royalty rates for the EVC main profile will be are not known.
3.MPEG-VCEG (Video Coding Experts Group) is working with VVC, not EVC.

WPP & SPLIT PARALLELISM options are not really maintained. Patches are still appreciated, but may be worked on only with very low priority.
Some comments:
JVET_O macros are normative changes. These can't just be turned off.

55:#include "mingw.mutex.h"

seems very platform specific.

Sorry for the late response. There was a press release after the Yokohama meeting: https://www.businesswire.com/news/ho...es-Work-Groups although it is only a very high level overview of the event - most of the actual work happens in the work groups.

Next MC-IF event will be held in Amsterdam during IBC: https://www.mc-if.org/ , direct link to: invitation letter

When do you think VVC will reach the market? When it does, will it be possible to use a PC with an old CPU to play AV1 and VVC videos if you buy a new video card?

It will be ratified by the end of 2020. Yes a new gpu that has a VVC hardware decoder would let you decode it smoothly.

It depends, AV1's software decoding is still progressing, but judging from the presentation, I still think VVC will be easier to decode than AV1, both in Hardware and Software.

Of course companies are waiting for licensing, which is what MC-IF was suppose to solve / improve. While there were no official announcement, I believe Velos Media wasn't listed in 2018, and it is now included in members page means All major player in the HEVC licensing are under MC-IF. Even those who refuse to participate with MPEG-LA or other patents pool are there as well like Technicolor.

This is a very encouraging sign. Hopefully the licensing terms will be out as soon as the codec get finalised.

Of course companies are waiting for listening, which is what MC-IF was suppose to solve / improve.

Yeah, so much about AV1's future is dependent on codec licensing and businesss issues that AOM has no control over.

VVC will definitely offer better compression efficiency than AV1, and it seems increasingly probably it can do so with fewer MIPS/watts/mm^2 of silicon.

Of course, the more viable AV1 is, the more pressure there would be on VVC patent holders to come up with a clearer licensing story than HEVC has been dealing with.
