Sprinkle more logging to make it easier to follow. Specify a low framerate and
capture resolution to avoid tests timing out. Make the sinks sync to test closer
to reality. Fix Makefile to use uninstalled interface.
* decouple image capturing from image post-processing and encoding
* post image-captured message after image is captured
* post preview-image message with snapshot of captured image
Don't allow setting filename via img-done signal parameter but force app
use filename property. Don't stop capture when setting filename property.
Update check unit test based on the change.
The video was recorded for too long for the test timeouts. Also the verification
suite did not had custom timouts at all. Also split the verification for images
and video to get better reporting.
Use playbin2 for validation. Use tmp_dir for capturing. Wait with g_cond for
burst capture finish. Cleanup some g_object_set. Add some logging to ease
tracing.
