Currently dx9screencapsrc prints a verbose warning in case the screen
index is out of range for the current number of detected monitors. This
value is then dropped.
However there is no initial indication (beside the console print) if it
worked or not. This may result in capturing an unwanted screen as it
would capture the last set index that was not rejected.
This patch sets the index regardless. Instead, the element throws an
error when it tries to run or getting caps for an invalid index.

In most display sink, the logic is to use as much as possible
of the given window. In this case, the window is the screen,
hence it's logical to scale up.
https://bugzilla.gnome.org/show_bug.cgi?id=767422
The source region was scaled for display before being passed
to drmModeSetPlane, which resulted in a portion of the video
being cropped. While when crop meta was present, the rectangle
was not centered since we where using unscaled width/height.

Some kms drivers demands specific pitches over the ones calculated by
GstVideoInfo. For example, intel driver demands strides round up 64.
This patch queries the driver for the prefered pitch and overwrites it
in the pool's GstVideoInfo structure.

This commit introduces IOSGLMemory which is a GLMemory that falls back to
GstAppleCoreVideoMemory for CPU access. This is a temporary solution until
IOSurface gets exposed as a public framework on iOS and so we can use

Building with Meson should work on both Linux and Windows, but may
need a few more tweaks on other operating systems.
_stdint.h is generated by Autotools and we don't really need it. All
supported platforms now ship with stdint.h. The only stickler was MSVC,
and since Visual Studio 2015 it also ships stdint.h now.
Uncompressed RGB frames can be (usually are) bottom-up
layout in DirectShow, and the code to flip them wasn't
properly ported from 0.10. Fix it.
Fix post-processing of RGB buffers. We need a writable
buffer, but the requests pool is holding an extra ref.
This could use more fixing to use a buffer pool
On the ODroid C1+ the H265 and H264 have the same name but are listed as two
different codecs. We have to handle them as the same one that supports both,
as otherwise we will register the same GType name twice which fails and we
then only have H265 support and not H264 support.
ahssrc is a new plugin that enables Gstreamer to read from the
android.hardware.Sensor Android sensors. These sensors are treated as
buffers and can be passed through and manipulated by the pipeline.

The calculation of the offset table was done base on a plane size
estimation. This does not always work. Instead, use memory offset the
same we as it's implement in GstVideoMeta map functions.
Without setting the DRM_CLIENT_CAP_UNIVERSAL_PLANES capability bit, only
overlay planes are made available for compatibility with legacy clients.
But if a CRTC doesn't have an overlay plane associated, then kmssink is
not able to find a plane for the CRTC and the pipeline will fail, i.e:
ERROR kmssink gstkmssink.c:482:gst_kms_sink_start:<kmssink0> Could not find a plane for crtc
If no overlay planes were found for a given CRTC, fallback to universal
planes so DRM will also return primary planes that can be used instead.

Rather than assuming something. e.g. zerocopy on iOS with GLES3 requires
the use of Luminance/Luminance Alpha formats and does not work with
Red/RG textures.

The hardware decoder can become (temporarily) unavailable across
VTDecompressionSessionCreate/Destroy calls. During negotiation if the currently
configured caps are still accepted by downstream we keep using them so we don't
have to destroy and recreate the decoding session.
This indirectly fixes https://bugzilla.gnome.org/show_bug.cgi?id=767429, by
making vtdec stick to GLMemory.
strcasecmp is not defined on MSVC, so just use the glib wrapper. Also pretend to
be Windows XP explicitly since the API we use was deprecated and removed
(ifdef-ed) from the SDK after this version of Windows. This will be especially
relevant once we stop supporting Windows XP soon:

The URI must already be escaped by the caller, we don't support passing around
invalid (unescaped) URIs via the GstURIHandler interface.
Also it will escape too much of the URI in this case, e.g.
ipod-library://item/item.m4a?id=3143338395173862951
becomes
ipod-library://item/item.m4a%3Fid%3D3143338395173862951

Move calling gst_vtdec_push_frames_if_needed from ::set_format to ::negotiate so
that we always drain even when renegotiation is triggered by downstream.
vtdec specifies sysmem; GLMemory as template caps. When negotiating, we used to
call gst_pad_peer_query_caps (..., filter) with our template caps as filter. The
query does gst_caps_intersect (filter, peercaps) internally which gives
precedence to the order of the filter caps. While we want to output sysmem by
default, when negotiating with glimagesink which returns GLMemory; sysmem; we
do want to do GL, so we now query using a NULL filter and intersect the result
with our template caps giving precedence to downstream's caps.
tl;dr: make sure we end up negotiating GLMemory with glimagesink
If for some reason the avdtpsink element can't go READY then the
gsta2dpsink can't either and so should release the ressources it
allocates when trying to do so.
Fix a leak with the generic/states test.

Similar to vtdec_hw, this commit adds a vtenc_h264_hw element that fails
caps negotiation unless a hardware encoder could actually be acquired.
This is useful in situations where a fallback to a software encoder
other than the vtenc_h264 software encoder is desired (e.g. to x264enc).
https://bugzilla.gnome.org/show_bug.cgi?id=767104
When renegotiating mid stream - for example with variable bitrate
streams - and therefore destroying and recreating VTSessions, the
hw decoder might become temporarily unavailable.
To deal with this and avoid erroring out on bitrate changes,
vtdec_hw now falls back to using the software decoder if the hw
one was available at some point but isn't anymore. At
renegotiation/bitrate change time, it will still retry to open
the hardware one.
::negotiate can be called several times before the CAPS event is sent downstream
so use the currently configured output state caps instead of the pad current
caps when deciding whether to recreate the VTSession or not.
This leads to creating/destroying less VTSessions which makes renegotiation more
reliable especially when using hw decoding.
There's no need for an end-of-list marker in the filter
PIDs array if full, as the absolute maximum number of
elements (MAX_FILTERS) is known.

This bug was found via cppcheck static analysis.
If android.hardware.Camera.getParameters returns NULL, then object will
be NULL, and we won't allocate params. This means that the GST_DEBUG
statement referencing params->object will be invalid. Fix this by
exiting early if android.hardware.Camera.getParameters returns NULL.

There is no way to tell one over the other when parameters
seem valid for DVB-T and DVB-T2 and the adapter supports
both. Reason to go with the former here is that, from
experience, most DVB-T2 channels out there seem to use
parameters that are not valid for DVB-T, like QAM_256
https://bugzilla.gnome.org/show_bug.cgi?id=765731
DVB-T/T2 have the same number of fields so we were
wrongly assuming DVB-T for DVB-T2 broadcasts. Not
setting the delivery system here allows for dvbsrc
to make an informed guess based on the channel
parameters.
When there's no explicit delivery system information
for a channel in the channel configuration file and
the user hasn't selected one via setting the delsys
property, we *guessed* it by selecting the last
supported delsys reported by the driver. This change
provides the basis for smarter delsys auto detection
and implements a rule for DVB-T2. Rules for other
delivery systems can be added in _guess_delsys() in
a similar way.
Additionally: Store list of adapter-supported
delivery systems instead of querying the driver each
time this information is needed.

The only mandatory frontend information for our use case
is its status. Make sure we output what we know instead
of choking at the first error getting SNR, BER or any of
the other informational parameters.
Some cameras (IDS) have broken DirectShow drivers which incorrectly fill some
fields in the VIDEOINFOHEADER structure; comparison between suggested and
supported media types in CBaseRenderer should ignore deprecated and/or not
essential fields; additionaly explicitely setting the mediatype for the capture
pin before trying to connect it works around another IDS driver bug, and
should have been already done anyway.

This patch requests for drmModePageFlip() for the used CRTC, if the kernel

Some presets are not always supported on all devices and will cause an error if
used. Specifically, the LOSSLESS presets are known to not work everywhere.
We have no idea which timestamps they are supposed to have so the only thing
we can do at this point is to drop them. Packets without timestamps happen if
audio was captured but no corresponding video, which shouldn't happen under
normal circumstances.

And creating one is causing assertions. Also get rid of the other CONSTRUCT
property as it's a) unneeded for default initialization and b) you're not
supposed to use constructor properties when creating element instances and the
GStreamer API doesn't provide direct ways for doing so.

In many cases, we use g_slice_new0 and then immediately overwrite the
allocated memory. This is inefficient. Since we're going to immediately

Currently, we use AHC*_CALL macros to call many of the Camera functions.
However, we already have helper classes to call the Camera functions, so
eliminate the macros.
As a nice side-benefit, we also get improved error handling and
reporting when something goes wrong calling these functions, because a
GError gets populated, and we log a GST_ERROR when something fails. This
was harder to do using macros, as all error handling was hidden from the
caller.

In the androidmedia plugin_init, we initialize various resources on the
Android device. If anything fails during this series of initializations,

this.

Leave kCVOpenGLESTextureCacheMaximumTextureAgeKey to the default (1s). We used
to set it to 0 and flush manually, but apparently (looking at the GLES profiler)
0 means "disable the cache entirely".
CPU waits are more expensive and are only required if the CPU is ever going to
access the data. GPU waits perform inter-context synchronisation and are cheaper
as they don't require CPU intervention.
When we are not waiting, we need to pass -1 to signal that we just want to check
that the frame was/n't rendered. Avoids waiting for frames that will never be
rendered.

Rework the GL context code. Now both avfvideosrc and vtdec can create an
internal GL context for pushing textures. Both elements will still try to
use/switch to a local context where available (including after RECONFIGURE
events).
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.
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.

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

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.
Moved the java wrapper API into its own files and made use of the
gst-dvm macros. Also renamed the API to have the proper naming
convention and coding style in order to match the one in androidcamera.
This is a work in progress! "android/media/MediaCodecList" is still missing
and the actual elements have not been ported to use the new function names.
