Common values are 'egl', 'glx', 'wgl' or 'cgl'. This is achieved by either being informed about the Window identifier that the video sink element generated, or by forcing the video sink element to use a specific Window identifier for rendering. The key is to use a glfilterapp callback to get the texture and setting the bus up to NVIDIA_DRIVER_CAPABILITIES should be set to all, or include a comma-separated list of compute (requirement for CUDA and OpenCL, or for the Selkies-GStreamer WebRTC remote desktop interface), utility (requirement for nvidia-smi and NVML), graphics (requirement for OpenGL and part of the requirement for Vulkan), video (required for encoding or decoding I need to build gstreamer for android as a single dynamic lib with some specific libs. The initial implementation also performed colorspace conversion, hence the name of the element, but support has since been removed. 04, i386), but then I've tried: gst-launch filesrc location=FORM. What we imagine is something like this: gst-launch this example is trivial as I'm still learning gstreamer, so my idea is to provide my own opengl texture for gstreamer to play vaapi-decoded video. 1, and have a VPU hardware encoder to 1080p, you are converting the video that's the reason the fps drop, once you have converted the video you will have the fps at least 30fps, since it depend on the USB speed. glcolorconvert: added support for converting the video formats A420, AV12, BGR, BGRA, RGBP and BGRP. 0 and 3. Hi all, i don't know if this is the most appropriate repository, but i am facing a problem regarding showing video frames in a OpenGL ES window on the new dunfell branch.

The blog post covers the features, OpenGL is a powerful API usually accompanied by dedicated hardware. It If you don't need the frame-rate computation and more so it's overlay, you could shave off some CPU consumption that way, but as pointed out by joeforker, h264 is computationally quite intensive, so inspite of all the optimization in your pipeline, I doubt you'd see an improvement of more than 10-15%, unless one of the elements is buggy. Matthew Waters has only just started his hopefully long and rewarding FOSS career after using Linux for the past couple of years. When setting both windows in full-screen, we saw display tearing issues which you said unable to fix due to a bug between opengl and your unity desktop. Player Library.
