DirectShow VCam source code

Posted on January 31, 2021 by Roman

Introducing another popular DirectShow project: Vivek’s source filter which emulates a video capture device. For a long time the code was hosted on P “The March Hare” W’s website, which was eventually taken down. I placed the recovered project, binaries, README and upgrade to Visual Studio 2019 on GitHub: roman380/tmhare.mvps.org-vcam: Original Vivek’s popular sample project…

The engineering quality of most recent Microsoft’s work around Media Foundation is terrible. It surely passes some internal tests to make sure that software items meet requirements of the use cases required for internal products, but published work gives impression that there is noone left to care about API offerings to wide audience. One new…

New AMD Radeon RX 6800 in real time low latency video encoding scenarios

Posted on December 25, 2020December 30, 2020 by Roman

AMD is not seemingly making any progress in improving video encoding ASICs on their video cards. New stuff looks pretty depressing. AMD Radeon RX 5700 XT was a bit of a move forward, a bit.

Updated NvcEncode: 5K and 8K low latency video encoding tester for NVIDIA GPUs

Posted on December 6, 2020 by Roman

Added a few more resolutions to NvcEncode tool. Resolutions above 4K are tried with H.264 codec but they are expected to not work since H.264 codec is limited to resolutions up to 4096 pixels in width or height. So the new ones apply to H.265/HEVC. They work pretty well on NVIDIA GeForce RTX 2060 SUPER:…
