Adds video-capture-width, video-capture-height and
video-capture-framerate properties to allow applications to
get/set those values. Getting was not possible before this patch,
and setting was done through the set-video-resolution-fps
action, which sets the properties and promptly resets the
video source to use them.
Fixes#614958
Adds image-capture-width and image-capture-height properties
to camerabin, allowing the user to get/set them. Getting was
not possible before and setting was done through the
set-image-resolution action, which shouldn't now just set
the properties.
Fixes#614958
Adds block-after-capture property to block running viewfinder after capturing.
This property is useful if application wants to display capture preview and avoid
running viewfinder on background.
Based on a patch by Tommi Myöhänen <ext-tommi.1.myohanen@nokia.com>
Adds a new property called viewfinder-filter to camerabin.
This property is used to add a filter to process the video
flow right before the viewfinder sink.
Also updates test to check property exists.
Add video-source-filter property that can be used to inject application
specific gstreamer element to camerabin pipeline. The video-source-filter
element will process all frames coming from video source.
One could add image analyzers to collect information about the stream,
or add image enhancers to improve capture quality, for example.
If source-resize flag is disabled then set resolution to image capture caps
according to capture resolution video source element produces. Otherwise we
write wrong resolution to image metadata.
This function is not supposed to dispose the element in the case of failure
as the caller is using the elements name in the error message. Also add
some more input parameter checks in the form of g_return_val_if_fail
Align element initialisation. This should be re-thought, g_object_new zeros things already.
Harmonize the element getters for the src/sinks to return what we actualy use.
This uses same approach like in playbin, namely checking for user defined
element, auto{audio,video}{sink,src} and finally DEFAULT_{AUDIO,VIDEO}{SRC,SINK}
defines from config.h.
Camerabin caches photography settings, but it didn't take into account
that scene mode setting may change other settings as well. So, config
needs to be read back from device after scene mode is set.
Camerabin incorrectly used G_GUINT64_CONSTANT macro for setting
"max-size-buffers" and "max-size-bytes" properties in image queue,
even when they aren't 64bit integers.
Camerabin sets itself to READY state during resolution change. This
operation makes output-selector to forget its currently active pad,
so it must be set again after state change.
If an error occurs, application should set pipeline to NULL, and updating
zoom can actually block message handling if video device driver has failed
and video src element supports zooming using photography interface and S_CROP.
