When the framesize is not specified, we try and calculate a size from
the strides and offset information. This was done with the sum of
offsets + the size of the last frame. That is just wrong method. We also
need to account for video meta that may be flipping two planes. An
example is if you convert I420 to YV12 by flipping the two last offsets.

Don't put relative paths in pkg-config files, including uninstalled
ones. For those, use @abs_topbuilddir@ and @abs_topsrcdir@ as we
do elsewhere.
Remove libraries= directives, which doesn't seem to be a pkg-config
variable that actually exists, but has been in all our pkg-config
files for as long as they've existed.
To make parser work with image having non-standard strides, plane
offsets or with padding between images.
For now, since element doesn't check for videometa, we can't directly
push buffers when these properties are set so it convert the frame
in the pre_push_buffer method to remove any custom padding.

Allows the subclass to completely override the chosen src caps.
This is needed as videoaggregator generally has no idea exactly
what operation is being performed.
- Adds a fixate_caps vfunc for fixation
- Merges gst_video_aggregator_update_converters() into
gst_videoaggregator_update_src_caps() as we need some of its info
for proper caps handling.
- Pass the downstream caps to the update_caps vfunc

1. Otherwise rotating the video will clip and show black bars due to
gltransformation's implementation.
2. The other option of make gltransformation aspect-agnostic produces
incorrect output with perspective transformations.
Actually set the configured framerate. Before we only used to set the first
matching framerate range. On iOS where the camera reports ranges [2, 60], we
used to configure the camera to output anything between 2 and 60fps.
Add a "mask" property that sets whether the edges by cvLaplace should be
used as a mask on the original input or not. The same way the original
image is copied to the edges in edgedetect.
Add a "mask" property that sets whether the detected derivative edges
should be used as a mask on the original input or not. The same way
the original image is added to the edges in edgedetect.
cvCvtPixToPlane() has been deprecated in OpenCV 3.0, and cvSplit() is the
suggested replacement. Since cvSplit() is available in OpenCV 2.4, it is
safe and cautious to update the function usage before it becomes an issue.
cvlaplace was also affected by the silent change in OpenCV API, same as
cvsobel. It hasn't been working for a while. It would return a plain black
image. This commit updates the usage of cvLaplace by using cvCvtColor to
create the grayscale intermediate image to process. This also means there
is no need anymore to use GstBaseTransform's transform_caps, since the pads
are RGB.
When sps data is NULL, the buffer allocated and mapped is not being freed.
In this scenario there is no need to allocate the buffer as we are supposed to return NULL.

The function gst_adaptive_demux_stream_update_source() function creates
a new GstPad called internal_pad. This pad is not freed when releasing
the stream.
The solution is to set GST_PAD_FLAG_NEED_PARENT so that the chain
functions do not get called when the pad has no parent and then
remove the parent in the gst_adaptive_demux_stream_free() function. This
causes the refcount of the pad to be set to zero.

Instead of just ignoring that error and then calling JNI functions with NULL,
which will kill the virtual machine.
The error handling here needs some further improvements though, errors in more
places are just ignored.
Happens when doing zerocopy rendering, or when passing a wrong index to it.
Handle this properly for zerocopy rendering, fail properly for the other
cases.

It's useful enough already to be used in other elements for audio aggregation,
let's give people the opportunity to use it and give it some API testing.

This branch adds support for Android Hardware Camera API through a new
element called ahcsrc. This is the "old" Android Camera API, then only
API available on Android 4.X.

Currently it was wrongly reporting min/max as being the shortest and
longest possible frame duration. This is not how latency works in
GStreamer.
Fix by reporting min latency as being the longest possible duration of
one frame. As we don't know how many buffers the stack can accumulate, we
simply assume that max latency is the same (the usual default behaviour).
_data_queue_item_free() calls gst_buffer_unref(), which
calls gst_ahc_src_buffer_free_func(), which calls
g_mutex_lock() on self->mutex and there you go... deadlock!
This commit is a part of portng android hardware camera from 0.10 implementation.
To preserve history and get diff clearly, the interesting files are moved to
deployment directory and the remaining files are removed.
