The URI attribute from the EXT-X-KEY tag and the URI attribute from the
EXT-X-I-FRAMES-ONLY tag are both quoted-string attibutes that have their
quotation marks removed during parsing. The CODECS attribute of the
EXT-X-STREAM-INF is also a quoted-string attribute, but this attribute
was not being un-quoted.
This commit changes the parser to always unquote all quoted-string
attributes and adjusts the unit tests to this new bevahiour for the
CODECS attribute.
An additional test is added to check that parsing of all of the fields
in the EXT-X-STREAM tag is correct, including those that contain comma
characters.

Using the new GstAdaptiveDemux test framework, add tests that
exercise hlsdemux. The following tests are added:
simpleTest
A simple playlist that contains some media URLs
testMediaPlaylist
A master playlist with a variant playlist that contains media URLs
testMediaPlaylistNotFound
A master playlist that points to a missing variant playlist
testFragmentNotFound
A master playlist with a variant playlist that contains media URLs
There is a missing media file referenced from the variant playlist.
testFragmentDownloadError
A master playlist with a variant playlist that contains media URLs
During the download of one media file, the test simulates the network
connection being dropped.
testSeek
A simple test of trying to perform a seek on an HLS stream.
To allow code from dash_demux.c to be used by other elements
that are based upon GstAdaptiveDemux, the code has been
refactored into four new files:
adaptive_demux_engine.[ch]
adaptive_demux_common.[ch]
The code in adaptive_demux_engine.c provides a generic
test engine for elements based upon GstAdaptiveDemux.
The code in adaptive_demux_common.c provides a set
of utility functions that are common between the tests
for hlsdemux and dashdemux.
As part of the refactoring, variables in structures were
renamed from using camelCase to underscore_case to match other
GStreamer source code.
The fake_http_src was renamed test_http_src and changed to use
callbacks to provide input data and error conditions. Rather than
using an array of input data that tries to encode all the
possible use cases for the GstTestHTTPSrc element, use a struct of
callbacks.
Users of this element are obliged to implement at least the src_start
callback, which provides a way to link from a URI to the settings
for that URI.
We need a static lock to protect various NVENC methods in _set_format(). Without
this the CPU use increases dramatically on initialisation of the element when
there are multiple elements being initialised at the same time.

Exposing the navigation thread's main context, GSourceFuncs and structs called
key_event and mouse_event is exposing a bit too much of the internals. Let's
just go with two functions to asynchronously send navigation events on the
window with the same API as the synchronous ones.
Clear error as soon as we determine that the download failed,
otherwise there are code paths where we might return without
clearing it ever, which would leak the GError then. Also, we
can pass a NULL GError pointer to _fetch_uri(), so just do that
instead of passing one that we're going to just free again
right away anyway.
This upload method detect and optimize uploads of DMABuf memory. This is
done by creating and caching EGLImages wrapper around DMABuf. The
EGLImages are then binded to a texture which get converter using
standard shader.
Example pipeline:
GST_GL_PLATFORM=egl \
gst-launch-1.0 v4l2src device=/dev/video1 io-mode=4 ! \
video/x-raw,format=NV12 ! glimagesink

Maps GstVideoFormats to suitable DRM fourccs which work with
glcolorconvert, using gst_gl_memory_alloc(). We require mostly
only 4 formats to be supported by the driver. We require DRM
equivalent to RGB16, RGBA, R8 and RG88. This way it's compatible with
DesktopGL, since GL_TEXTURE_2D is used and limit driver requirements.
With this we can virtually support all formats the glcolorconvert
supports.

Adds more meaningful error than
"Failed to convert multiview video buffer", which is always used
when prepare_next_buffer() fails in gst_glimage_sink_prepare().

Update opencvtextoverlay to inherit from GstOpencvVideoFilter instead of
from GstElement. This means less code and more uniformity with other OpenCV
elements. The chain/transform function is now a third of the size than
before.
Update pyramidsegment to inherit from GstOpencvVideoFilter instead of from
GstElement. This means less code and more uniformity with other OpenCV
elements.

When the mode of decklinkvideosink is set to "auto", the sink claims to
support the full set of caps that it can support for all modes. Then, every
time new caps are set, the sink will automatically find the correct mode for
these caps and set it.
Caveat: We have no way to know whether a specific mode will actually work for
your hardware. Therefore, if you try sending 4K video to a 1080 screen, it
will silently fail, we have no way to know that in advance. Manually setting
that mode at least gave the user a way to double-check what they are doing.

Update motioncells to inherit from GstOpencvVideoFilter instead of from
GstElement. This means less code and more uniformity with other OpenCV

Otherwise qtkitvideosrc fails to build on OSX 10.10.4
because QTKit has been deprecated since OS X 10.9.
Also set -mmacosx-version-min=10.8 in front to allow
the user or cerbero to override the version.

Add gst_gl_memory_allocator_get_default to get the default allocator based on
the opengl version. Allows us to stop hardcoding the PBO allocator which isn't
supported on gles2.
Fixes GL upload on iOS9 among other things.
Performing any GL function marshalling off the GL thread with glimagesink's
render lock is prone to deadlocks between the GL thread and the non-GL thread.
What can happen is this:
1. non-GL thread attempts to function marshal to the GL thread.
2. while 1 is happening, the winsys gives an event (say resize)
3. This calls back into glimagesink which taks the render lock.
4. As the GL function marshalling is attempting to run on the GL
and already has glimagesink's render lock locked. This deadlocks
as the threads are waiting for each other.
Update edgedetect to inherit from GstOpencvVideoFilter instead of from
GstElement. This means less code and more uniformity with other OpenCV
elements.
e.g when wrapping a data pointer we don't want to map/unmap off the end of
pointer with the alignment bytes.
Instead track that information separately as maxsize is used for mapping by
GstMemory and thus represents a size without any alignment padding bytes.
Adding the support for the two other OpenCV linear filters to smooth
images. The new API does support spatial sigma in the bilateral filter,
hence bringing that property back.
Adding reference to new documentation.
While encoding the frame in ASCII mode, per component four bytes are needed
and after every 20 bytes, a \n will be added. So the calculation should be
size = size * (4 + 1 / 20). This should exclude the header being written.
Since header is also being included in the calculations, memory mishandlings
are happening.
