gst_buffer_pool_get_config() returns a copy to the bufferpool's
configuration, which must be passed to gst_structure_free() after
use if not given away to gst_buffer_pool_set_config().

gst_pad_get_pad_template_caps() returns a reference which is unreferenced,
so creating a copy using gst_caps_copy() results in a reference leak.

gst_pad_get_pad_template_caps() returns a reference which is unreferenced,
so creating a copy using gst_caps_copy() results in a reference leak. Also
the caps are pushed as an event downstream, but this doesn't consume the
caps so it must still be unreferenced.

When a seek with a negative rate is requested, find the target
segment where gstsegment.stop belongs in and then download from
this segment backwards until the first segment.
This allows proper reverse playback.
If window is resized, GstStructure pointer values have to be rescaled to
original geometry. A get_surface_dimensions GLWindow class method is added for
this purpose and used in the navigation send_event function.

32 bit integers are going to overflow, especially the PCR offset to
the first PCR will overflow after about 159 seconds. This makes playback
of streams stop at 159 seconds as suddenly the timestamps are starting
again from 0. Now we have a few more years time until it happens again
and 64 bits are too small.
Otherwise pic timing structure can have invalid cpb_removal_delay,
dpb_output_delay or pic_struct_present_flag which are blindly retrieved
in h264parse.

When flushing, this will prevent dashdemux from trying to download more
fragments or more chunks of the same fragment before stopping.
Also improves the error handling to not transform everything non-ok into
an error.

Certain elements expect that there be a certain number of lines
that they can write into. e.g. for odd heights, I420, YV12, NV12,
NV21 (and others) Y lines are expected to have exactly twice the
number of U/UV lines.

templatematch operates on BGR data. In fact, OpenCV's IplImage always
stores color image data in BGR order -- this isn't documented at all in
the OpenCV source code, but there are hints around the web (see for
example
http://www.cs.iit.edu/~agam/cs512/lect-notes/opencv-intro/opencv-intro.html#SECTION00041000000000000000
and http://www.comp.leeds.ac.uk/vision/opencv/iplimage.html ).
gst_templatematch_load_template loads the template (the image to find)
from disk using OpenCV's cvLoadImage, so it is stored in an IplImage in
BGR order. But in gst_templatematch_chain, no OpenCV conversion
functions are used: the imageData pointer of the IplImage for the video
frame (the image to search in) is just set to point to the raw buffer
data. Without this fix, that raw data is in RGB order, so the call to
cvMatchTemplate ends up comparing the template's Blue channel against
the frame's Red channel, producing very poor results.
