009e4522bf decoder: h264: add support for constrained baseline profile.
Recognize streams marked as conforming to the "Constrained Baseline
Profile". If VA driver supports that as is, fine. Otherwise, fallback
to baseline, main or high profile.

Constrained Baseline Profile conveys coding tools that are common
to baseline profile and main profile.

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.

1b500dee54 Allow build against either GStreamer API (0.10 or 1.0).
Introduce a new configure option --with-gstreamer-api that determines
the desired GStreamer API to use. By default, GStreamer 1.0 is selected.
Also integrate more compatibility glue into gstcompat.h and plugins.

51151e7aa1 Add initial support for GStreamer 1.0.
This integrates support for GStreamer API >= 1.0 only in the libgstvaapi
core decoding library. The changes are kept rather minimal here so that
the library retains as little dependency as possible on core GStreamer
functionality.

e7e5c74a6e decoder: use GstVideoCodecState.
Use standard GstVideoCodecState throughout GstVaapiDecoder and expose
it with a new gst_vaapi_decoder_get_codec_state() function. This makes
it possible to drop picture size (width, height) information, framerate
(fps_n, fps_d) information, pixel aspect ratio (par_n, par_d) information,
and interlace mode (is_interlaced field).

This is a new API with backwards compatibility maintained. In particular,
gst_vaapi_decoder_get_caps() is still available.

b963ccb929 profile: match video/x-h263 as H.263 Baseline profile.
HACK: qtdemux does not report profiles for H.263. So, assume plain
"video/x-h263" is H.263 Baseline profile.
