GStreamer & Media Foundation

Posted on November 8, 2020 by Roman

More of unusual stuff: mix of Media Foundation pipeline, with a custom media source specifically, with GStreamer pipeline. It appears that with all bulkiness of GStreamer runtime, the framework remains open for integrations and flexible for a mix of pre-built and custom components. PoC push source plugin on top of Media Foundation media session and…

Incorrect video output of NVIDIA H.264 Encoder MFT

Heterogeneous Media Foundation pipelines

Posted on May 9, 2020May 28, 2020 by Roman

Just a small test here to feature use of multiple GPUs within single Media Foundation pipeline. The initial idea here is pretty simple: quite so many systems are equipped with multiple GPUs, some have “free” onboard Intel GPU idling in presence of regular video card. Some other systems have integrated “iGPU” and discrete “dGPU” seamlessly…
