The default for tagsetters is to use merge keep mode, so tags
would never be replaced and all captures would have the same tags.
This commit watches all elements added into encodebin and sets
all tagsetters to merge replace mode
Using serialized custom events for switching image capture saving
location makes camerabin2 save each capture correctly to the location
that was set during the moment start-capture was called, and not
the moment the filesink was writing to disk.
This prevents captures to be overwriten by racyness among start-capture
and setting location for images.
We only need to change the state of the filesink to switch its
saving location. This might still cause some problems of dropping
captured buffers, but it is better than changing the state of
the whole branch.
Camerabin2 allows setting a filter for image, video or viewfinder, but
not one filter for all three at the same time. I added a filter to
wrappercamerabinsrc to allow setting a global filter when using this
source.
https://bugzilla.gnome.org/show_bug.cgi?id=649822
Some properties (like viewfinder-filter) only are taken into use
on NULL->READY transitions and the get/set property was returning
the currently in use value, instead of the last set.
This is bad, as after setting 'a' to 'x', you expect that getting 'a'
will return 'x'. This patch fixes it.
If needed, later we could add current-* properties that are readonly
and get the current value in use.
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.
