[Bug 770535] Playbin fails to decode stream when gst-vaapi is installed

[GStreamer (GNOME Bugzilla)]

https://bugzilla.gnome.org/show_bug.cgi?id=770535

--- Comment #1 from Víctor Manuel Jáquez Leal <vjaquez at igalia.com> ---
The error is actually

:00:01.280772134  1240      0x23e76d0 DEBUG            vaapidecode
gstvaapidecode.c:1205:gst_vaapidecode_sink_getcaps:<vaapidecode0> Returning
sink caps EMPTY

This means that the codec profile is not supported by the hardware.

Checking the logs of the media the codec profile is

video/x-h264, parsed=(boolean)true, stream-format=(string)byte-stream,
alignment=(string)nal, width=(int)1196, height=(int)720,
framerate=(fraction)0/1, profile=(string)baseline, level=(string)3.1

And h264 baseline profile is not supported by Haswell.

The interesting part is that playbin, in the case of local media, can change to
other available decoder (libav, for example) if this happens in
gstreamer-vaapi; but in this case of remote media, it doesn't, it just drops
the negotiation.
