Chrome platform supports FLAC encoding in ISO BMFF (fragmented MP4) media since version 62 (October 2017), however the support for FLAC (and Opus) overall did not become standard and comprehensive since then. I hooked up Microsoft FLAC Audio Encoder MFT into media streaming application to produce media and check browser compatibility. /audio.mp4?flac – produces FLAC…
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…
I mentioned issues in AMD’s and Intel’s video encoding related drivers, APIs and integration components. Now I switched development box video card to NVIDIA’s and immediately hit their glitch too. NVIDIA GeForce RTX 2060 SUPER offers really fast video encoder and consumer hardware from AMD and Intel is simply nowhere near. 3840×2160@144 video can be…
There is some support for Opus in Windows, unfortunately however it is not documented. IIRC it came to extend media codec support in Microsoft Edge browser, and since internally Microsoft Edge is using standard platform media API Media Foundation, the decoder came in format of Media Foundation Transform. It is interesting that Opus decoding was…
The previous post was focusing on problems with the hardware MFT decoder provided as a part of video driver package. This time I am going to mention some data about how the inefficiency affects performance of video capture using a high frame rate 260 FPS camera as a test stand. Apparently the effect is better…
Fancy stuff goes first: This is an application that renders this shadertoy by Taron into a video file with requested metrics. Why? it looks great it is a source of content used for various development and testing purposes
Even though AMD H.264 Video Encoder Media Foundation Transform (MFT) AKA AMDh264Encoder is, generally, a not so bad done piece of software, it still has a few awkward bugs to mention. At this time I am going to show this one: the video encoder transform fails to acquire synchronization on input textures. The problem comes…
