When switching capture caps, camerabin1 resets its state to ready
to force a new caps to be negotiated. This causes ongoing captures
to be aborted.
This commit adds a condition to wait for captures to finish before
going to ready state.
This patch removes the audio source buffer probe that was used
to re-timestamp buffers to make them start from 0. As muxers
have been fixed to use running time instead of timestamps, this
is not needed anymore.
Fixes bug #646211
Remove the android/ top dir
Fixe the Makefile.am to be androgenized
To build gstreamer for android we are now using androgenizer which generates the needed Android.mk files.
Androgenizer can be found here: http://git.collabora.co.uk/?p=user/derek/androgenizer.git
Don't use g_idle_add() and friends to schedule things we can't do from the
streaming thread in another thread. The app may not be running the default
GLib main loop. Instead, just spawn a thread.
Also, we need to care for when acessing a pad variable, as another thread
might have taken camerabin to NULL while this gst_camerabin_imgbin_finished
didn't run.

The videobin and imagebin from camerabin have their states
locked and aren't put to READY when all the rest of camerabin
is set to it.
This might cause one of them to be still processing and post
an EOS after camerabin isn't expecting it anymore, this causes
an assertion as the processing counter would already be 0 and
would be decremented.
If videobin/imagebin was never set to READY state the ownership
of elements created and set by application were never taken by
bin and therefore gst_object_sink is called for these elements
before unreffing (they may still be in floating state and not
unreffed properly without sinking first)
When select-all was set, input-selector wasn't handling upstream events.
Now input-selector forwards the event to all of its sink pads. This
changes the input-selector internal to camerabin until it is replaced
with a better solution.
The "select-all" property was removed when input-selector was moved
to core, but camerabin uses this, so make camerabin use a private
copy until a better fix is found.
No need to check if camerabin is on video mode if it isn't on
image mode as those are the only 2 modes available.
Additionally, if mode gets corrupted somehow and would be neither
image or video it would cause a null pointer dereferencing some
lines of code below, so this is safer.
As imgbin_finished() is scheduled from g_idle_add, it might
be run a little later than expected, this can lead to the application
setting camerabin to ready before imgbin_finished() runs. In this case,
the processing counter goes to 0 and an assertion happens.
This patch relaxes the imgbin_finished() check on the processing
counter.
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
