the init.mp4 can be expanded with strftime the same way as
hls_segment_filename.

Also changes some default values for options after this change.
This makes distinction between feedback and wet option.
Before they would produce same output if values were swapped.
They add considerable complexity to frame-threading implementation,
which includes an unavoidably leaking error path, while the advantages
of this option to the users are highly dubious.
It should be always possible and desirable for the callers to make their
get_buffer2() implementation thread-safe, so deprecate this option.
This patch introduces a new frame side data type AVFilmGrainParams for use
with video codecs which support it.
It can save a lot of memory used for duplicate processed reference frames and
reduce copies when applying film grain during presentation.
This patch adds a select_region option to the xcbgrab input device.
If set to 1, the user will be prompted to select the grabbing area
graphically by clicking and dragging. A rectangle will be drawn to
mark the grabbing area. A single click with no dragging will select
the whole screen. The option overwrites the video_size, grab_x, and
grab_y options if set by the user.
For testing, just set the select_region option as follows:
ffmpeg -f x11grab -select_region 1 -i :0.0 output.mp4
The drawing happens directly on the root window using standard rubber
banding techniques, so it is very efficient and doesn't depend on any
X extensions or compositors.
