<p>With an Intel or AMD GPU, hardware decoding with the gstreamer open-source VAAPI gstreamer plugin is preferable. The open-source “Nouveau” drivers for NVIDIA graphics are also in principle supported: see <a href="https://nouveau.freedesktop.org/VideoAcceleration.html">here</a>, but this requires VAAPI to be supplemented with firmware extracted from the proprietary NVIDIA drivers.</p></li>
<li><p><strong>NVIDIA with proprietary drivers</strong></p>
<p>The <code>nvh264dec</code> 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 <code>libcuda.so</code> is installed. This plugin should be used with options <code>uxplay -vd nvh264dec -vs glimagesink</code>. For GStreamer-1.16.3 or earlier, replace <code>nvh264dec</code> by the older plugin<code>nvdec</code>, which must be built by the user: See <a href="https://github.com/FDH2/UxPlay/wiki/NVIDIA-nvdec-and-nvenc-plugins">these instructions</a>.</p></li>

<li><p><strong>Video4Linux2 support for the Raspberry Pi Broadcom GPU</strong></p>
<p>Raspberry Pi (RPi) computers can run UxPlay with software decoding of h264 video (by adding <code>-avdec</code> to the uxplay options) but this usually has unacceptable latency, and hardware-accelerated GPU decoding should be used. The unmaintained 32-bit-only omx (OpenMAX) driver used for this by <a href="http://github.com/FD-/RPiPlay">RPiPlay</a> is no longer officially supported by RPi OS (Bullseye): the replacement is v4l2 (Video4Linux2). Fixes to the GStreamer v4l2 plugin that allow it to work with UxPlay on RPi are now in the GStreamer development branch, and will be available in the upcoming GStreamer-1.22 release, A (partial) backport (as <code>gstreamer1.0-plugins-good-1.18.4-2+~rpt1</code>) has already appeared in RPi OS updates. Until the full update appears, or if you are using a different distribution, you can find <a href="https://github.com/FDH2/UxPlay/wiki/Gstreamer-Video4Linux2-plugin-patches">patching instructions for GStreamer</a> in the <a href="https://github.com/FDH2/UxPlay/wiki">UxPlay Wiki</a>. Patches are available for all GStreamer releases 1.18.4 and later.</p></li>
