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 and powered by GStreamer with OpenGL rendering. Can also be used as a pre-made widget for GTK 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:
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:
Other required plugins (codecs) depend on video format.
Installation
Run in terminal:
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:
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.
