If playbin3 is available (checked in Gstreamer registry), it
makes sense to prefer it given the major improvements and
features it offers including the capability to handle higher
bitrates.

- Keep the playbin name for pl
Once it is determined that an Intel GPU is available/active (after
looking into udev's database), we try to see if there is a h/w
based encoder (element) available (in Gstreamer's registry cache)
for the user selected video codec. In other words, if we find that

We first try to detect if an Intel GPU is available (by looking into
udev's database) and then probe Gstreamer's registry cache to see
if there is h/w based decoder (element) available for the incoming
video codec format. If both these conditions are satisfied (i.e,

Given that libudev is widely available on many Linux distros, we
can use the relevant APIs to iterate over all the devices associated
with the drm subsystem to figure out if a specific vendor GPU
is available or not.
This capability (identifying GPU Vendor) is useful to determine
whether to launch
If we use the x264enc encoder to encode a stream, then videoconvert
would convert the BGRx data into Y444, which is the preferred format
for x264enc. However, some decoders particularly the ones that are
h/w based cannot work with Y444 if it was the format used by the
encoder. Therefore, to address
This patch series includes a patch for Spice (server) to
automatically select h/w based encoder elements and another one
for Spice-gtk (client) to automatically select h/w based decoder
elements with Intel GPUs when these two conditions are met:
- An Intel GPU is available and is active
- The relev
