gcc 4.5 warns when comparing some integer with an enum value, in
the case of GstFlowReturn this is valid though. We should later
add GST_FLOW_CUSTOM_OK1, GST_FLOW_CUSTOM_OK2, etc. after new core
is released.
Commit message copied from core's commit from Benjamin Otte:

Apparently gcc warns that GstMiniObject is not castable to
GstEvent/Message/Buffer due to them containing 64bit variables, even
though ARM hackers claim that those only need 4byte alignment. And as
long as gcc behaves that way, this warning is not very useful.
So we'll remove the warning until this problem is fixed.
Fixes#615698
Add a script that creates elements based on any of the GStreamer
base classes. It isn't very user friendly at the moment, one
needs to edit the script to make it work properly. Each base class
has a template file describing what to put into the constructed
element. Eventually, these templates should be moved to reside
with the base class source and installed to a well-known directory,
where an installed script could find them.
The template files use the .c ending so editors know they are C
source, but gst-indent doesn't handle them correctly. So they
need to be committed with -n. Ugh. I'll try to figure out a fix
for that soon.
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.
It's an external which lives in gstcheck.c. Redeclaring it makes some
compilers/architectures think the 'buffers' in the individual tests are
a different symbol... and therefore we end up comparing holodecks with
oranges.
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.
When iterating the formats table, we can just pass the whole
entry to our helper function, which avoids iterating the table
again to find the entry structure from the passed format id.
Also accept formats that are not natively supported by the
hardware, OSS4 can convert them internally. List the native
formats first in the caps though, to express our preference
for the native formats. We need this in order to support the
case properly where the audio hardware supports only e.g.
little endian PCM, but the host is big endian, since many
audio elements only support native endianness and make the
reasonable assumption that any audiosink will be able to
handle audio in native endianness.

Fixes#614317.
We wait to parse a minimum number of frames (10, arbitrarily) before
emiting bitrate tags so that our early estimates are not wildly
inaccurate for streams that start with a silence. If the stream ends
before that, we just emit the tags anyway.
While it _would_ be nicer to be specify the threshold to start pushing
the tags in terms of duration, this would introduce more complexity than
this merits.

The current code just uses table id, subtable extension and version number to
check if the section has been seen before. However, this comparison is not
sufficient, causing actually new tables being dismissed.
Fixes bug #614479.
