In the case of OpenGL based elements, the buffers have the GstVideoGLTextureUploadMeta meta, which
efficiently copies the content of the VA-API surface into a GL texture.

Clapper uses `OpenGL` based sinks, so when `VA-API` is available, both CPU and RAM usage is much lower.
Clapper uses `OpenGL` based sinks, so when `VA-API` is available, both CPU and RAM usage is much lower. Especially if you have `gst-plugins-bad` 1.18+ with new `vah264dec` decoder which shares a single GL context with Clapper and uses DRM connection. If you have an AMD/Intel GPU, I highly recommend this new decoder.
To use `VA-API` make sure you have `gstreamer1-vaapi` installed. Verify with:
To use `VA-API` with H.264 videos, make sure you have `gst-plugins-bad` 1.18+. For other codecs additionally install `gstreamer1-vaapi`. Verify with:

## Requirements
Clapper uses `GStreamer` bindings from `GI` repository, so if your distro ships them as separate package, they must be installed first.
Clapper uses GTK4 along with `GStreamer` bindings from `GI` repository, so if your distro ships them as separate package, they must be installed first.
Additionally Clapper requires these `GStreamer` elements:
* [gtkglsink](https://gstreamer.freedesktop.org/documentation/gtk/gtkglsink.html)
* [gtk4glsink](https://gstreamer.freedesktop.org/documentation/gtk/gtkglsink.html)
* [glsinkbin](https://gstreamer.freedesktop.org/documentation/opengl/glsinkbin.html)
**Attention:** `gtk4glsink` is my own port of current GStreamer `gtkglsink` to GTK4. The element is not part of GStreamer yet (pending review). Fedora package is available in my OBS repository. It will be installed along with Clapper if you add my repo to `dnf` package manager. Otherwise you might want to build it yourself from [source code](https://gitlab.freedesktop.org/Rafostar/gst-plugins-good/-/tree/GTK4) of my gstreamer GTK4 branch.
Other required plugins (codecs) depend on video format.
