The doc says to use gst_element_send_event on the pipeline, but if
we are to call it on the element itself, it's a noop. This should make it
handle the event properly before delegating it to basesrc.
Use guint instead of guint16 to represent the size of the encoded image,
this would make some recombined images lose most of their data and
show like a big black image with a small line of content on top.
Also adds a minor log message.
EOI are not always at the last 4 bytes. We need to search
the last 5 bytes to find the 0xFFD9 sequence as jpegenc seems
to round the buffer size to the next 4 multiple.
The PES header length is calculated before setting the dynamic flags, returning
a wrong value. Small frames that should be sent in a single TS packet are
spawned to a new packet because of that error. For audio streams where a single
frame can cope in one TS packet it introduces a huge overhead.
For a 100B packet, we prepare a TS packet with a payload of(100+9)B. Then, we
write the TS header using this value in tsmux_write_ts_header, and call
tsmux_stream_get_data(). The dynamic flags where not set yet and now
tsmux_stream_pes_header_length() returns 14B instead of 9B. The payload of the
TS packet is 114B, 5B more than what was calculated. 109B are sent in a first
packet and the remaining 5B are sent in another one.
Fixes bug #628548.
The mutex locked is for the 'mux' object, but we unlock the
pad, which means that if the rtpmux gets a flush, then the
object lock will stay locked forever, causing it to freeze
the next time it tries to take it.
Fixes bug #627991
Rework bulge mapping function to give more predictable results.
Now the bulge is done dividing by a scale factor that smoothsteps from
"zoom" at the center to 1.0 at "radius".

This could happen because for example /usr/lib is linked
to /usr/lib64 and both are loaded. The frei0r specification
says that the plugin init function must only be called once
and for some plugin weird things (including crashes) are
happening.
Fixes bug #623710.
Make the "radius" property of CircleGeometricTransform relative.
This is more coherent with the way [x,y]-center properties are handled
and allow to set a radius without knowing the video size.
Radius is defined with respect to the circle circumscribed about the
video rectangle so that a point in the center has radius 0.0 and one in
a vertex has radius 1.0.
Note that this is not a regression from the previous absolute way of
defining the radius as a user who knows the video size can easily
calculate the relative radius and set that.

Currently implemented switching from yuv to rgb, looking up rgb from the
table in the usual way, getting back to yuv. With luma lookup presets
(sepia, heat, xray) a color space conversion is saved directly looking
up rgb for a given Y and converting to yuv.
Probably this latter step can even be made faster precalculating a luma
to yuv table in an outer loop.

Implements a color lookup table filter with 4 presets:
- heat: fake heat camera effect
- sepia: sepia toning
- xray: invert + shade to blue
- xpro: cross process

Ports gleffects "fisheye" filter to geometrictransform.
Fake fisheye lens filter. Somewhat empiric implementation because I
didn't find any good algorithm that does it with nice results.

Ports gleffects "mirror" filter to geometrictransform.
Simple yet effective mirror effect, splits the image into halves and
reflect the first into the second.

Ports gleffects "square" filter to geometrictransform.
Maps a region around the center into a zoomed square and smoothly get
back to normal zoom. With faces it makes a funny "cube-face" effect.
