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

The calculation of the offset table was done base on a plane size
estimation. This does not always work. Instead, use memory offset the

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.

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

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

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

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.

Some cameras (IDS) have broken DirectShow drivers which incorrectly fill some

And creating one is causing assertions. Also get rid of the other CONSTRUCT

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.

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

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.

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).

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.
The on_preview callback gets called with NULL if the buffer in the queue is
too small, so we need to handle the case where the array is NULL. Also
there is a bug in the android source which makes it drop one of the buffers
so if we had 5 buffers, and we renegotiate to a higher resolution, then we'd
only get 4 calls to on_preview_frame with NULL, with one being dropped.
This means we can't reallocate the buffers in the if (data == NULL) case
because we might end up with 0 buffers in the end.
Implement a new memory type wrapping CVPixelBuffer.
There are two immediate advantages:
a) Make the GstMemory itself retain the CVPixelBuffer. Previously,
the containing GstBuffer was solely responsible for the lifetime of
the backing CVPixelBuffer.
With this change, we remove the GST_MEMORY_FLAG_NO_SHARE so that
GstMemory objects be referenced by multiple GstBuffers (doing away
with the need to copy.)
b) Delay locking CVPixelBuffer into CPU memory until it's actually
mapped -- possibly never.
The CVPixelBuffer object is shared among references, shares and
(in planar formats) planes, so a wrapper GstAppleCoreVideoPixelBuffer
structure was introduced to manage locking.

When doing GLMemory avfvideosrc negotiates UYVY. This change allows avfvideosrc
! tee name=t ! ... ! glimagesink t. ! ... ! gldownload ! vtenc_h264 ! ...
to do GLMemory and 0-copy with the encoder (with the CV meta).
Change texture format from BGRA to NV12. This allows a pipeline like avfvideosrc
! tee name=t ! ... ! glimagesink t. ! ... ! gldownload ! vtenc_h264 ! ... to
negotiate GLMemory. This makes the glimagesink branch much faster (obviously)
and triggers the 0-copy path between avfvideosrc and vtenc (using the CV meta).
Combined this results in a huge perf improvement on iOS (25-30% of CPU time in a
pipeline like the one above).
Note that this doesn't introduce a new shader conversion in the sink, since BGRA
textures had to be copied/converted from format=BGRA,texture-target=RECTANGLE to
format=RGBA,texture-target=2D anyway.
Fixate to the highest possible resolution and fps. Otherwise by default we end
up fixating at 2fps and the lowest supported resolution, which is hardly what
someone who bought an overpriced smartphone wants.
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.

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.
