Looks like nowadays VA-API is force disabled in Totem, in which case this comparison does not seem fair.

# Clapper
|
|
A GNOME media player built using [GJS](https://gitlab.gnome.org/GNOME/gjs) and powered by [GStreamer](https://gstreamer.freedesktop.org) with [OpenGL](https://www.opengl.org) rendering. Can also be used as a pre-made widget for [GTK](https://www.gtk.org) apps.
|
|
|
|
### WORK IN PROGRESS
|
|
This is still early WIP. Many features are not implemented yet and quite a few are still unstable. Right now Clapper can only play single file. So if you want to test it, start it from terminal like this:
|
|
```shell
|
|
clapper video.mp4
|
|
```
|
|
## Requirements
|
|
Clapper uses `GStreamer` bindings from `GI` repository, so if your repo 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)
|
|
* [glsinkbin](https://gstreamer.freedesktop.org/documentation/opengl/glsinkbin.html)
|
|
|
|
Other required plugins (codecs) depend on video format.
|
|
|
|
## Installation
|
|
Run in terminal:
|
|
```sh
|
|
sudo ./install.sh
|
|
```
|
|
I know that this should be done using some sort of build system (like `meson`), but the player is still far from finished and a basic install script should be sufficient for the time being, if anyone wishes to test it.
|
|
|
|
## Hardware acceleration
|
|
Using hardware acceleration is highly recommended. As stated in `GStreamer` wiki:
|
|
```
|
|
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.
|
|
|
|
To use `VA-API` make sure you have `gstreamer1-vaapi` installed. Verify with:
|
|
```shell
|
|
gst-inspect-1.0 vaapi
|
|
```
|
|
On some older GPUs you might need to export `GST_VAAPI_ALL_DRIVERS=1` environment variable.
|
|
|
|
Other acceleration methods (supported by `GStreamer`) should also work, but I have not tested them due to lack of hardware.
