ChromaLog2WeightDenom = luma_log2_weight_denom + delta_chroma_log2_weight_denom
The value of ChromaLog2WeightDenom should be in the range of 0 to 7 and
the value luma_log2_weight_denom should be also in the range of 0 to 7.
Which means , delta_chroma_log2_weight_denom can have values in the range
between -7 and 7.

The current code was ignoring the par/dar aspect when transforming
from window coordinates to stream coordinates resulting in incorrect
coordinates being sent upstream in the navigation events.
String parameters are expected to be passed as (f0r_param_string *),
which actually map to char**. In the filters this is evaluated as
(*(char**)param) which currently lead to crash when passing char*.
Remove the special case for string, all types, including char* as
passed as a reference.

The payloader didn't copy anything so far, the depayloader copied every
possible meta. Let's make it consistent and just copy all metas without tags or
with only the audio tag.

Checking the vector is not empty and checking the vector size is greater
than zero are the same thing, this is a redundancy in the code. Only
checking the vector is not empty is sufficient, therefore removing the
other check.
Adding this private header to the list of sources. We don't want to make
this header public, but we need it in the list of sources otherwise it
won't be included in the tarball. This fixes make distcheck.
This regression was introduced by commit 1a6fe3db
The variables to store face values are only needed if they will be used to
control the volume. Which isn't the default to avoid potentially being very
loud accidentally. Only create variables when needed.

Add a pivot vector for setting the origin of rotations and scales.
With the pivot point the rotation and scale operations can have
different origins. This adds the ability to rotate around different points.
Currently the default (0, 0) pivot point is possible,
a rotation around the center, and zooming into and out of the center.
With an pivot point this is optional.
I defined the following image coordinates for the pivot point:
(-1,1) ------------------------- (1,1)
| |
| |
| |
| (0,0) |
| |
| |
| |
(-1,-1) ------------------------- (1,-1)
Example:
Rotate the video at the bottom left corner
gst-launch-1.0 videotestsrc \
! gltransformation \
scale-x=0.5 \
scale-y=0.5 \
rotation-z=25.0 \
pivot-x=-1.0 \
pivot-y=-1.0 \
! glimagesink
The pivot-z option defines the pivot point in 3D space.
This only affects rotation, since we have no Z data to scale.
With this option a video can be rotated around a point in 3D space.
Example:
Rotate around point behind the video:
gst-launch-1.0 videotestsrc \
! gltransformation \
rotation-x=10.0 \
pivot-z=-4.0 \
! glimagesink
Depending on the bytes order we will get BGRA (little) and ARGB (big)
from the composition overlay buffer while our GL code expects RGBA. Add
a fragment shader that do this conversion.

Check if downstream is seekable via a SEEKING query and output a
BYTE segment if we want to seek back to fix up the headers later,
but if we're streaming send a TIME segment instead (which goes
down better with e.g. asfmux ! rtpasfpay).

Since the profile gchar depends on DEFAULT_FACE_PROFILE, it should never be
NULL. Furthermore CascadeClassifier accepts any input, even
an empty one, but if the profile fails to load it returns an empty cascade.
Check for this instead, and inform the user if there was an Error.
Some video bitstreams report a too restrictive set of profiles. If a video
decoder was to strictly follow the indicated profile, it wouldn't support that
stream, whereas it could in theory and in practice. So we should relax the
profile restriction for allowing the decoder to get connected with parser.

The gst_dash_demux_stream_update_fragment_info function could call
gst_dash_demux_stream_update_headers_info function twice. The
gst_dash_demux_stream_update_headers_info function will set header_uri and
index_uri to some newly allocated strings. The values set by the first call of
gst_dash_demux_stream_update_headers_info will leak when the function is
called for a second time.
The solution is to call gst_adaptive_demux_stream_fragment_clear before the
second call of gst_dash_demux_stream_update_headers_info

Check if profile is NULL before dereferencing it with new. Also, new will
never return NULL; if allocation fails, a std::bad_alloc exception will be
thrown instead. Remove check for a NULL return.

Also implement framerate handling correctly by borrowing the code from
ximagesrc. GstBaseSrc::get_times() can't be used for that, we have to
implement proper waiting ourselves.
The ref_object and object parameters were the wrong way around.
For the typical use case where an application is setting a
GstControlBinding on the returned ghost pad:
1. our control binding would be removed when the new one was set
2. sync_values calls were not being forwarded from the internal
pad to the ghost pad.
If an application attempts to perform other control binding
operations (get_* family of functions) on the internal pad, they
will also be forwarded to the ghost pad where a possible
GstControlBinding will provide the necessary values.
