[Spice-devel] [spice-gtk v1 4/4] channel-display-gst: early return if gst_init failed

[Victor Toso]

From: Victor Toso <me at victortoso.com>

If gst_init() fails, gstvideo_init() will warn once about the issue
and never attempt to try again, which is probably fine.

All the other APIs that might be called such as
create_gstreamer_decoder() should not fail silently.
