Versatile Video Coding (VVC) / H.266: HEVC successor

[birdie]

And here's a 2023 codec adoption roadmap from Rethink Technology Research:

How about PUs of I frames? extract the 4x4's PUs of each I frame separately in VVCSoftware_VTM?

I don't think this is question for this forum. You have to be codec developer.

These are the functions for JCTVC HEVC
ctu->getTotalNumPart() == 256
ctu->getDepth(48) == 3
ctu->getPredictionMode(48) == INTER_MODE
ctu->getPartitionSize(48) == Nx2N

ptu->getTotalNumPart() == 256
ptu->getDepth(48) == 5
ptu->getPredictionMode(48) == INTRA_MODE
ptu->getPartitionSize(48) == NxN
Your case is definitely Intra mode and depth 5. For VVC max CU is 128x128. I just don't know what the function equivalents are in JVETVVC. Officially JVETVVC isn't PTU function
partitioner.currPartIdx() == 256
partitioner.currDepth == 5

MSU has released "MSU Video Codecs Comparison 2022".

Tencent-TVC and Tencent266 codecs have beaten everything under the sun but you cannot download or use either.

And here's a August 2023 VVC adoption report from Streaming Media.

Meanwhile there's been no news in regard to x266 but H2 is not over yet.

Chinese BS...

Out of tree native VVC decoder for FFMpeg is now complete.

Now idea when it's gonna get merged.

Decoder is currently only 10bit 420/422 and doesn't support Intra Block Copy and Palette.

Well, just discovered it on GH:

• Xin26x is an univeral video encoder framework, which can accommodate all video coding standard on this planet so far.
• It is optimized for real time video communication, live streaming application and offline video encoding.
• It currently supports HEVC, AV1(I frame), VVC video coding standards.
• It is a very high performance encoder.
• It is well-structured for understandability, maintainability and scalability.
• It is written from scratch and has a plain C API to enable a simple integration into other software.
• It is very small footprint encoder, it takes very small memory requirement under restricted mode.

According to the Git, it's buildable and working (even if not complete -> check Todos)

Does anyone tested it ?

Hope this gets merged soon into FFmpeg master. But the thread executor is also still missing.

Edit: Now it is not missing anymore.

Probably the first Android ROM with built in VVC support (it's not specified whether it's for encoding or decoding, I guess it's decoding only):

For OnePlus 9.

Software decoder or actual hardware one?

You can bet 100% it's a software decoder. There's been no SoCs for mobile phones with HW VVC decoding support yet.

I have a sneaking suspicion Qualcomm Snapdragon 3 will be the first to support HW VVC decoding. We'll learn about that in just a few months.
