handle the case where encodebin doesn't have the pad
camerabin2 is requesting, either because of its current profile
or because of missing elements, making it fail to provide
the pad
Use merge replace mode to allow new tags to override old ones
and fix the use case where the last sent tags should be serialized
to the captured images.
In video mode the tags should be pushed after sending the start capture
to the source, this allows the video recording elements to be reset
and leave the flushing state they were at after a previous capture.
This fixes the problem where tags only work for the first video capture
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
Instead of probing the videosink sinkpad for passing EOS, better
to wait for EOS from the bus.
This makes sure the filesink has already processed it and is
ready to close the file. This is used to notify applications
that camerabin2 is idle and can be shut down.
This is not implemented in any of our real sources to which wrappercamerabinsrc
might connect but this is optional and can be implemented at any time. A
limit on the software zoom level using video{crop,scale} would be arbitrary.
Use resource warning messages to notify camerabin2 that a capture
as aborted or couldn't be started, making it decrement the
processing counter and making the idle property more reliable.
Setting the audio source to null isn't needed and it could
make the EOS that is still flowing be dropped if autoaudiosrc
is used because its pads go flushing before the EOS gets pushed
from the real source.
When recording 2 videos in sequence with the same video-capture-caps,
the second video would get a not-negotiated error because the
src caps were being cleared without any intention of
renegotiating it back to the requested capture caps.
This patch avoids this caps reset procedure unless a new
caps was set.
Don't leak string copy returned by gst_element_get_name(). Also, check
for certain elements by checking the plugin feature / factory name, not
the assigned object name.
We can't rely on audio sources pushing EOS when going PAUSED->READY
because this is a basesrc bahavior and when used inside autoaudiosrc
the ghostpad goes flushing before the real source pushes the EOS,
so it is dropped.
Audio elements are put into bin only when needed, so we need
to be careful with their states as camerabin2 won't manage
them if they are outside the bin.
Also we should reset their pad's flushing status before
starting a new capture.
Adds an audio source and audio capsfilter/queue/convert, creating
a new branch on camerabin2 that is used to feed encodebin with
audio buffers for video recording.
Adds properties to check what caps are supported on the
viewfinder (from the camerasrc viewfinder pad) and another
one to set a caps for the viewfinder.
Use video_renegotiate and image_renegotiate booleans to make
the videosrc negotiate the capture caps on the first capture because
the caps might be set before wrappercamerabinsrc goes into PLAYING
and pads drop the internal renegotiate event.
This is required as the output-selector is using the 'none' negotiation
mode.
When setting the internal capsfilter caps for capture we should put
the full caps instead of trying to fixate it ourselves. This way we let
the elements (and mostly the source) select the best format instead
of defaulting to what the pad fixation function picks.
Image previews where being posted in sync with the buffers
timestamps, this makes no sense as previews should be posted ASAP.
Also adds some debugging messages.
Camerabin2 uses state changes to force the source to renegotiate its
caps to the capture formats. The state changes makes the source lose
its clock and base_time, causing it to stop timestamping the buffers.
We still need a proper way to make sources renegotiate its caps, so this
patch is a hack to make the source continue timestamping buffers even
after changing state. The patch works by getting the clock and base
time before doing the state change to NULL and setting them back
after putting it to PLAYING again. It also cares to drop the first
new segment after this state change.
When going to ready, camerabin2 could create an empty file
if the videosink was put to ready. This patch only puts videosink
to ready on the PAUSED_TO_READY state change if it is on PAUSED
or PLAYING.
