This patch refactors imagebin element creation and linking into separate functions,
and adds re-using also for imagebin internally created elements.
So this refactoring allows creating imagebin elements already in NULL state when
application sets the image mode, and next state change from NULL to READY will be faster.
This reduces first capture latency.
Earlier the elements were both created and linked in NULL to READY state change.
Adds 'idle', a read-only boolean property that tells applications
if there is any capturing/saving/encoding going on in camerabin. If
not, it is safe to set it to NULL and release resources without
losing data.
Add "ready-for-capture" property to indicate if preparing a new
capture is possible.
"ready-for-capture" changes before the 'image-done' signal, so
the application can be notified that it can do a new capture
even before the previous one has finished encoding/saving.
When switching between video/still modes the pre-night-mode fps
should be reset to prevent it being used in the incorrect mode, causing
the videosource to fail configuring itself
Store width/height/fps for video captures in a separate variable
than the one that stores the currently used value.
This prevents the user preferences to be lost when resetting
the currently used dimensions for night mode, for example
Resets used caps so that camerabin doesn't try to use them
when restarting, where elements/properties might have changed
and the old caps be incompatible
Adds a higher priority to the idle_add function for when
the image bin finished the image capture. This reduces the
delay for the application to be notified about this.
As camerabin only gets notified of the changes from the
video source element, it should query the initial value
once the source is created so it initializes itself
correctly.
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
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
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.
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.
