If bo allocation failed we destroy the buffer and return GST_FLOW_ERROR,
but the @buffer pointer was still pointing to the address of the
destroyed buffer. gst_kms_sink_copy_to_dumb_buffer() was then trying to
unref it when bailing out causing a crash.
Leave @buffer untouched if allocation failed to fix the crash.
Also remove the check on *buffer being not NULL as gst_buffer_new()
will abort if it failed.

HRESULT is unsigned long on Windows, but the Decklink headers define
it to 'int' on Linux. Confusingly, the defines that talk about the
possible return values for it use long constants. The easy fix would
be to change the linux/LinuxCOM.h header, but that's copied from the
decklink SDK.
Change the logging to always upcast to unsigned long while printing
HRESULT for consistency across platforms.

The default memory allocator of the decklink library allocates
a fixed pool of buffers, and the number of buffers is unknown.
This makes it impossible do useful queuing downstream. The new
memory allocator can create an unlimited number of buffers,
giving all queuing features one would expect from a live source.

In this patch we keep track of the cached kmsmem in a way
that we can clear the cache during the drain process. This
release the framebuffer before waiting for the next vblank,
hence add support for DRM driver (like Intel one) that release
the associated DMABuf reference asynchronously.
https://bugzilla.gnome.org/show_bug.cgi?id=782774
kmssink keeps a reference on the last rendered buffer. If this buffer
refers to an upstream buffer, it should be should be released on DRAIN
and ALLOCATION queries so all upstream buffers can be returned to the
pool if needed. As the buffer may be used for scanout, we copy this
buffer into a dumb buffer prior to let it go.
Based on patch from Guillaume Desmottes <guillaume.desmottes@collabora.com>
https://bugzilla.gnome.org/show_bug.cgi?id=782774
This otherwise breaks DMABuf reclaiming. This is not visible from
userspace, but inside the kernel, the DRM driver will hold a ref to the
DMABuf object. With a V4L2 driver allocating those DMABuf, it then
prevent changing the resolution and re-allocation new buffers.

Milliseconds was wrong and made use of this timeout quite
confusing. The code uses the value as microsenconds so
any meaningful number was off by orders of magnitude.
Set the pts and dts on the frame that we receive from the msdk.
Also fix the inverted logic in setting sync points, previously we
were marking all frames as sync points except IDRs.
https://bugzilla.gnome.org/show_bug.cgi?id=782801
When extracting an aux buffer from an MJPG carrier, at
*least* put the original timestamp on it, even if we
fail to apply any other timestamp (which we always do
at the moment, because the timestamp calculating code
was never finished). Apply a DTS using the camera
supplied delay value as well, assuming that there's
no re-ordering going on (there isn't in the C920,
which is really the only extant camera doing this
stuff) and a warning if that turns out not to be true.
This is basically a frame counter provided by the driver and it's
advancing at the speed of the HDMI/SDI input. Having this available on
each buffer allows to know what constant-framerate-based timestamp each
frame is corresponding to and can be used e.g. to write out files
accordingly without having the local pipeline clock timestamps used.
https://bugzilla.gnome.org/show_bug.cgi?id=779213
The main advantage is that our sleeps can be interrupted in case of
an src_reset(). Earlier, we would need to wait for a read to complete
before we could do a reset, which could take a long time.
https://bugzilla.gnome.org/show_bug.cgi?id=781249
The audio packet times can be completely unrelated to the video stream
time, depending on the card. While this looks like a bug in the driver,
just always using the video stream time (which is correct) works as a
workaround for now.
Earlier, the plugin was ignoring those settings and blindly setting
buffer-time to 2 seconds and latency-time to 200ms, which forced all
pipelines to have a minimum latency of 200ms + sink latency.
The values of segsize and segtotal were also not derived correctly.
Now we obey these values, and you can get close to the previous
behaviour by setting buffer-time and latency-time manually. Note that
they are set in microseconds.
As a consequence, when we haven't received enough data from the
device, we now sleep for a time proportional to the data remaining.
However, Directsound is a deprecated API so it maintains its own
software ringbuffer which updates at arbitrary intervals. Hence we
might have to wait a full segsize to get the last 10% of data. To
avoid tight loops, we clamp our sleep floor at 10ms.
In my testing, this keeps the wakeups not-too-high (proportional to
the latency-time set on the source). Further improvements should be
made by fixing the WASAPI audio source plugin instead of this.
Directsound is deprecated and as the comments explain, it is
impossible to get low latency, decent quality, or good performance
from it.

segsize should be based on latency-time, and must be a multiple of the
frame size. segtotal should be based on buffer-time and segsize.
This prevents errors caused by outputting buffers that are not a
multiple of the frame size, and actually makes the buffer-time and
latency-time properties do what they're supposed to do.

First of all, all the HD and UHD modes should be top-field-first, as

Then we should include the caps field "field-order" in the caps of the

And finally we should set the TFF flag on interlaced buffers that are

On some hardware the first few frames are bogus and not very useful.

Based on this we calculate the actual capture time, which should get us
rid of any capturing jitter by averaging it out.
Also add a output-stream-time property which forces the elements to
output the stream time directly instead of doing any conversion to the
pipeline clock. Use with care.
https://bugzilla.gnome.org/show_bug.cgi?id=774850
The hardware timestamps have no relation to when frames were produced,
only when frames arrived somewhere in the hardware. Especially there is
no guarantee that audio and video will have the same hardware timestamps
although they belong together, and even more important: the rate with
which the hardware timestamps increase is completely unrelated to the
rate with which the frames are captured!
As such we can as well use the pipeline clock directly and stop doing
complicated calculations. Also as a side effect this allows now running
without any pipeline clock, by directly making use of the stream times
as reported by the driver.

ipod-library://item/item.m4a?id=3143338395173862951
becomes

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

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
module suppports async page flip. If it does not, the element requests for a
vblank event. A GstPoll waits for the event to happen.

This patch will enable the import of dmabufs into a KMS buffer using
the PRIME kernel interface.
If the driver does not support prime import, the method is skipped.

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
overwrite it, we might as well use plain g_slice_new.

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,
we need to deinitialize any initializations that already occurred.
However, we don't do so if we fail to register the ahcsrc element. Fix
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.
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.
