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
Uses new x264 API to apply reduced complexity values to the parameters to
increase encoding speed in the first pass of a multi-pass encode. This does
not impact on final quality.
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.
Addresses part of bug #607798
If it is enabled, then it will be main profile instead of baseline.
This ensures maximum compatibility of the output stream until the
encoder configuration interface gets an overhaul with explicit
output profile selection.
Fixes#619776.
Fix off-by-one bug when constructing the avcC header chunk: we
wrote wrong profile info into the header. The first byte in the
SPS NAL we get from x264 is the nal type, not the profile_idc.
Also add some debug logging.
Fixes#610089.

Do not manipulate input timestamps on the way out,
since that shifts the timeline and A/V sync.

Try harder not to crash when we get an EOS event but haven't set
up the encoder yet (as may happen when upstream errors out with
not-negotiated, for example). Also, always push the EOS event
downstream.
