FFmpeg Merges Vulkan Video Encode Support

([Vulkan] 3 Hours Ago Vulkan Video Encoding)


Since the release of FFmpeg 6.1 last year there has been [1]accelerated Vulkan Video decoding support while being merged to FFmpeg Git this weekend is the Vulkan Video encode support.

The latest Vulkan Video patches by Lynne have now been upstreamed into FFmpeg for enabling GPU accelerated video encoding using this cross-vendor, cross-OS API. This Vulkan Video encode support is currently in place for H.264 and H.265.

This Vulkan Video encode support is now in [2]FFmpeg Git ahead of the project's next release.

Great seeing more driver and multimedia software support around Vulkan Video continuing to materialize albeit rather slowly. Mesa's Intel ANV driver [3]supports H.264/H.265 encode as does [4]the RADV driver too since earlier in the year.

After this was written there appeared a remarkable posthumous memoir that
throws some doubt on Millikan's leading role in these experiments. Harvey
Fletcher (1884-1981), who was a graduate student at the University of Chicago,
at Millikan's suggestion worked on the measurement of electronic charge for
his doctoral thesis, and co-authored some of the early papers on this subject
with Millikan. Fletcher left a manuscript with a friend with instructions
that it be published after his death; the manuscript was published in
Physics Today, June 1982, page 43. In it, Fletcher claims that he was the
first to do the experiment with oil drops, was the first to measure charges on
single droplets, and may have been the first to suggest the use of oil.
According to Fletcher, he had expected to be co-authored with Millikan on
the crucial first article announcing the measurement of the electronic
charge, but was talked out of this by Millikan.
-- Steven Weinberg, "The Discovery of Subatomic Particles"

Robert Millikan is generally credited with making the first really
precise measurement of the charge on an electron and was awarded the
Nobel Prize in 1923.
