Seekability, like duration, etc is unlikely to change (frequently), and
the default assumption covers most cases, so let subclass set when needed.
At the same time, allow subclass to indicate if it has seek-metadata (table)
available, and possibly have it provide an average bitrate.
This allows the child class to chain its event handler with
GstBaseParse, so that subclasses don't have to duplicate all the default
event handling logic.

If the elements are in NULL/READY and changing state to
PAUSED/PLAYING while a capture is started
camerabin might not set the active_bin properly causing the
capture start to fail.
This patch fixes it by checking the current and pending state
of the branches instead of only the current one
The vertigo plugin for example claims to have 3 properties but
the 3rd property does nothing and has a NULL name.
Fixes bug #630783.
Thanks to Martti Kühne for debugging this.
Initialize interval_ts to first QOS event timestamp, otherwise the
fps statistics are printed always after one rendered frame.
Also, initialize last_frames_* counters, the values are bogus e.g. after
PLAYING-NULL-PLAYING state change.
Remove the weird (failing) code to figure out caps on the srcpad.
Add a caps property to decide what caps to put on the outgoing buffers.
Fix an event leak.
Add a property to avoid redirection to the rtsp-sdp:// url but instead embeds an
rtspsrc element inside sdpdemux as the session manager.
Based on patch by Marco Ballesio.
Fixes#630046
Adds another boolean to help controlling viewfinder blocking,
making it possible for the applications to reset the viewfinder
blocking after capture was started but before the blocking
actually happens.
Unblock the viewfinder when going to ready to avoid
blocking when setting camerabin to playing again and
attemping to capture. Keep the property as is.
Remove notify signal proxy for video-source. Application can use
video-source directly from now on to get notified of property changes.
Add monitoring scene-mode property change to select lowest possible
framerate for video capture when night mode is selected.
Fixes#616923
Work in progress. Colorspace handles most format conversion using
3-stage getline/matrix/putline process using an AYUV or ARGB
intermediate, with most functions handled by Orc. There is also
a table of single-pass conversions, all handled by Orc. The plan
is to add optional stages for various chroma upsampling/downsampling
algorithms, dithering, and float/int16 intermediates, and then have
Orc create multi-stage functions at runtime.
When we find an SDP with an rtsp:// url as the global control attribute or when
all streams have an rtsp:// control attribute, post an redirect message with an
rtsp-sdp:// url containing the SDP.
Fixes#628214
This makes it able to recombine rgb images, making it possible
to add tags to rgb jpegs as well.
Uses a simple strategy to check what are the possible colorspaces
and avoid adding jfif to ones that aren't YUV/Gray.
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.
https://bugzilla.gnome.org/show_bug.cgi?id=625722
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.
https://bugzilla.gnome.org/show_bug.cgi?id=625722
Ports gleffects "stretch" filter to geometrictransform.
Shrinks the image around the center and gradually return to normal zoom
creating funny caricatures.

Adds the new 'gaudieffects' plugin, originally found
here: http://github.com/luisbg/gaudi_effects
Contains the following video effect elements: burn, chromium, dilate,
dodge, exclusion and solarize.
Thanks to Jan Schmidt for the reviewing and refactoring
And don't fail if a plugin was already registered. Frei0r allows
plugins in directories with higher importance to override plugins
from directories with lower importance.
This writes out the optional 'btrt' atom (MPEG4BitrateBox) for H.264
media if either or both of average and maximum bitrate are available for
the stream.

This collects the 'bitrate' and 'maximum-bitrate' tags on the
corresponding pad and uses these to populate these fields in the ESDS
where applicable.

Factor out most of the buffer handling and implement a chain_list
function. Also, the DTMF muxer has been modified to just have a
function to accept or reject a buffer instead of having to subclass
both chain and chain_list.
This is a problem if you tune to a channel which uses pid X and later tune to
another channel where X is used for another table (e.g. PMT).
The code that does that was actually already there but never used because the
pat structure was freed before. The commit that introduced those lines intended
to fix a memory leak, but we clean things up elsewhere.
Fixes#622725.
Write uint tags that have complements (e.g. track-number/
track-count) even when we only have one of them available
and set the other one to 0.
Fixes#622484
Adds a signal for applications to receive the fps measurements made
instead of only printing them to the frame/stdout.
This signal is only emited if the signal-fps-measurements property
is set to TRUE
Previously we would end up with the collectpaddata structure already freed.
This would result in a bogus iteration of mux->sinkpads (all the
GstQTPad being freed) and it wouldn't be removed from that list.
Finally, due to it not being removed from that list, we would end up
calling a bogus gst_qt_mux_pad_reset on those structures => SEGFAULT
Having GST_DEBUG_CATEGORY and GST_DEBUG_CATEGORY_EXTERN together
might lead to 'undefined symbol' problems. This commit moves
the _EXTERN to a separate new file.
