15519ebe3d legal: add per-file authorship information. 
Credit original authors on a per-file basis as we cannot expect people
to know all country-specific rules, or bother browsing through the git
history.

f34b6ffc60 libs: add gst_vaapi_video_format_from_string() helper. 
Add gst_vaapi_video_format_from_string() helper function to convert from
a video format string representation to a suitable GstVideoFormat. This
is just an alias to gst_video_format_from_string() for GStreamer 1.0.x
builds, and a proper iteration over all GstVideoFormat string representations
otherwise for earlier GStreamer 0.10.x builds.

8ffe11a9df libs: add gst_vaapi_video_format_from_va_fourcc() helper. 
Add gst_vaapi_video_format_from_va_fourcc() helper that converts from a
VA fourcc value to a suitable GstVideoFormat.

4a8a80061f libs: add and expose gst_vaapi_video_format_to_string() helper. 
This is just a wrapper over gst_video_format_to_string() for older
GStreamer 0.10 builds.

7fa4973f8a Fix new video format API. 
Fix new internal video format API, based on GstVideoFormat, to not
clobber with system symbols. So replace the gst_video_format_* prefix
with gst_vaapi_video_format_ prefix, even if the format type remains
GstVideoFormat.

e3da054e48 surface: add helper function to get chroma type from GstVideoFormat. 
Add gst_video_format_get_chroma_type() helper function to determine
the GstVaapiChromaType from a standard GStreamer video format. It is
possible to reconstruct that from GstVideoFormatInfo but it is much
simpler (and faster?) to use the local GstVideoFormatMap table.

430598cf00 Add new video format API. 
Leverage GstVideoFormat utilities from core GStreamer to provide an
adaptation layer to VA image formats.
