For NVIDIA graphics with the proprietary drivers, the nvh264dec plugin (included in gstreamer1.0-plugins-bad since GStreamer-1.18.0) can be used for accelerated video decoding on the NVIDIA GPU after NVIDIA’s CUDA driver libcuda.so is installed. This plugin should be used with options uxplay -vd nvh264dec -vs glimagesink. For GStreamer-1.16.3 or earlier, the plugin is called nvdec, and must be built by the user: see these instructions. This older form of the NVIDIA plugin should be used with the -vd nvdec -vs glimagesink uxplay options.
GPU Support for Raspberry Pi
-Raspberry Pi (RPi) computers can run UxPlay with software decoding of h264 video (by adding -avdec to the uxplay options) but this usually has unacceptable latency, and hardware-accelerated decoding by the Pi’s built-in Broadcom GPU should be used. RPi OS (Bullseye) has abandoned the unmaintained 32-bit-only omx (OpenMAX) driver used for this by RPiPlay, in favor of v4l2 (Video4Linux2). A GStreamer Video4Linux2 plugin that works with UxPlay is now in the GStreamer-1.21.0.0 development branch, and will only be available in the forthcoming GStreamer-1.22 release, but a (partial) backport (as gstreamer1.0-plugins-good-1.18.4-2+~rpt1) for RPi OS (Bullseye) has already appeared in its current updates. Until the promised full update appears, or if you are using a different distribution, you can find patching instructions for GStreamer in the UxPlay Wiki. Patches for GStreamer-1.18.5 (for Ubuntu 21.10), 1.18.6, 1.20.0, 1.20.1 (for Ubuntu 22.04 and Manjaro) and 1.20.2 are also available.

Some Linux distributions such as Debian do not allow distribution of compiled GPL code linked to OpenSSL-1.1.1 because its “dual OpenSSL/SSLeay” license has some incompatibilities with GPL, unless all code authors have explicitly given an “exception” to allow such linking (the historical origins of UxPlay make this impossible to obtain). Other distributions treat OpenSSL as a “System Library” which the GPL allows linking to.
