Question regarding --chroma sample position: is it 2 for HDR?
Description of the parameter in the help text: "The chroma sample position when chroma 4:2:0 is signaled: unknown, vertical, colocated"

It is 2 for UHD HDR Blu-ray. Although I'm skeptical that end-to-end support is reliably implemented; a number of devices ignore the metadata and assume it is 0 like everything was forever. At 2160p getting it wrong is nigh invisible. I do worry about a 360p OTT HDR stream, though, as a half pixel is a 720p pixel.

mozilla has removed AV1 support from firefox 121 on windows and now requires you to install the Microsoft AV1 Video Extension from microsoft store instead: https://www.mozilla.org/en-US/firefo.../releasenotes/
This is likely due to avanci demanding royalties from AV1 streaming. |

AV1 software decoding is still there. The extension is required for HW decoding. Windows LTSC doesn't have the extension installed by default and millions of people use this version of Windows because it's the version to use. Unfortunately MS for some reasons decided not to include HW video decoding with this Windows SKU. |

It seems to me that avifenc may support SVT-AV1 as one of several encoders. A recent build v1.0.4 does contain strings with related messages. But I doubt it contains code, and the help output doesn't mention it either. Does anyone know facts?
PS: The repo readme suggests that it has to be enabled in CMake options... maybe M-AB-S can do that for the 64-bit version. PPS: Well, that was simple. Last edited by LigH; 21st May 2024 at 21:06. |
