Makes x264 select its stream-format based on what's available
on caps, the user selected option will be chosen as a fallback
when both options are available.
https://bugzilla.gnome.org/show_bug.cgi?id=644233
Use of a rate control method (pass, bitrate, quantizer, etc properties), a
preset and possibly a profile and/or tuning are now the recommended way to
configure x264 through x264enc.
If a preset/tuning are specified then these will define the default values and
the property defaults will be ignored. After this the option-string property is
applied, followed by the user-set properties, fast first pass restrictions and
finally the profile restrictions.
Addresses part of bug #607798
- Make defaults append the appropriate default value to a string. This is
needed to differentiate between something user-set and the actual prop
default.
- Add an internal option string to which _set_property () cases append for the
majority of properties.
- Use gst_x264_enc_parse_options () to clean up application of settings. This
will make order of application with respect to the presets and tunings quite
simple.
Addresses part of bug #607798
In X264_BUILD >= 86 there is a new API for applying restrictions to an H.264
Profile. This makes it easier to achieve Baseline Profile for example.

Original commit message from CVS:
* ext/x264/gstx264enc.c: (gst_x264_enc_reset),
(gst_x264_enc_chain), (gst_x264_enc_encode_frame):
* ext/x264/gstx264enc.h:
Do not deal with duplicated input (timestamps). If needed,
a generic element can do so.
Do not manipulate input timestamps on the way out,
since that shifts the timeline and A/V sync.

Check for sufficiently up-to-date x264 API.
