For example this allows the omx decoder to directly fill the
pixmaps coming from the video sink.
It only avoids a buffer copy when the decoder uses a pool provided
by a downstream element. So let's restrict this usage to situations
where the decoder decides to use a downstream buffer pool.
Tested with Tizonia/OMX.Aratelia.video_decoder.vp8
and with Bellagio/OMX.mesa.video_decoder.avc.
If it fails to setup buffers with OMX_UseBuffer the decoders
fallbacks to usual OMX_AllocateBuffer.
Also it allows to test on desktop the GstOMXBufferPool->other_pool
management which was previously only used in the OMX_UseEGLImage
case, i.e. on Rpi.

This information can be useful to zynqultrascaleplus decoders. They may
use this information to reduce startup latency by configuring itself
before receiving the first frames.
We also have a custom OMX extension allowing the decoder to report the
latency. The profile/level information helps it reporting a more
accurate latency earlier.

It is safe to ignore it always. Tizonia notifies this error to pass
some khronos conformance tests. Problem is that gst-omx saves this
error in comp->last_error and then gst_omx_port_set_enabled early
error out which fails the pipeline.

Ensure that enough buffers are allocated by adding up component's own
minimal plus the number of buffers requested by downstream.
This should prevent buffers starvation problem if downstream elements
are holding some of the buffers they required.
Also simplify the check on the maximum on buffers. What we actually care
about is to make sure the pool can hold the minimum of required buffers.

Some platforms may not implement OMX_IndexConfigVideoAVCIntraPeriod and
use OMX_IndexParamVideoAvc instead to configure the GOP pattern.
So raise a warning instead of an error if this API is not implemented.

The decoder only requires to receive one frame per buffer which is
already enforced with 'alignment=au'. There is no need to require to
have a parser upstream.
Allow to run "encode ! decode" pipeline without having a parser.

The OMX specification defines two API to set the AVC profile and level:
using OMX_VIDEO_PARAM_PROFILELEVELTYPE and OMX_VIDEO_PARAM_AVCTYPE.
We were already supporting the former but not the latter. We are now
setting both so implementation don't have to rely on a specific one.

The OMX_VIDEO_CONFIG_AVCINTRAPERIOD.nPFrames setting isn't of any use on

Previously the omx plugin was blacklisted if GST_OMX_CONFIG_DIR
points to an invalid path or if the gstomx.conf contains 0 valid
component.
Problem is that once the plugin is blacklisted, a rescan is not
triggered upon changes of the env var or the gstomx.conf file
despite being setup with gst_plugin_add_dependency.
This also makes it more consistent with other plugins that auto
generate features. For example gst-{ffmeg,libav}, gstreamer-vaapi,
v4l2 video dec.
To clarify the diff, the plugin_init func will return TRUE even if
g_key_file_get_groups returns 0 element and even if
g_key_file_load_from_dirs fails.

The omxvideodecoder class only checks some of the caps parameters but if

There is one rare case where calling handle_messages() more than once can cause a deadlock
in the video decoder element:
- sink pad thread starts the src pad task (gst_omx_video_dec_loop())
- _video_dec_loop() calls gst_omx_port_acquire_buffer() on dec_out_port
- blocks in gst_omx_component_wait_message() releasing comp->lock and comp->messages_lock
(initially, there are no buffers configured on that port, so it waits for OMX_EventPortSettingsChanged)
- the sink pad thread pushes a buffer to the decoder with gst_omx_port_release_buffer()
- _release_buffer() grabs comp->lock and sends the buffer to OMX, which consumes it immediately
- EmptyBufferDone gets called at this point, which signals _wait_message() to unblock
- the message from EmptyBufferDone is processed in gst_omx_component_handle_messages()
called from gst_omx_port_release_buffer()
- gst_omx_port_release_buffer releases comp->lock
- the src pad thread now gets to run, grabbing comp->lock while it exits from _wait_message()
- _acquire_buffer() calls the _handle_messages() on the next line after _wait_message(),
which does nothing (no pending messages)
- then it goes to "retry:" and calls _handle_messages() again, which also does nothing
(still no pending messages)
- scheduler switches to a videocore thread that calls EventHandler, informing us about the
OMX_EventPortSettingsChanged event that just arrived
- EventHandler graps comp->messages_lock, but not comp->lock, so it can run in parallel at
this point just fine.
- scheduler switches back to the src pad thread (which is in the middle of _acquire_buffer())
- the next _handle_messages() which is right before if (g_queue_is_empty (&port->pending_buffers))
processes the OMX_EventPortSettingsChanged
- the buffer queue is still empty, so that thread blocks again in _wait_message()
- the sink pad thread tries to acquire the next input port buffer
- _acquire_buffer() also blocks this thread in:
if (comp->pending_reconfigure_outports) { ... _wait_message() ... }
- DEADLOCK. gstreamer is waiting for omx to do something, omx waits for gstreamer to do something.
By removing those extra _handle_messages() calls, we can ensure that all the checks of
_acquire_buffer() will re-run. In the above case, after the scheduler switches back to
the middle of _acquire_buffer(), the code will enter _wait_message(), which will see that
there are pending messages and will return immediately, going back to "retry:" and
re-doing all the checks properly.

Interlaced stream could make the decoder use two input frames to produce
one output frame causing the gstvideodecoder frame list to grow.
Assuming the video decoder output frame in display order rather than in
decoding order, this commit add a way to release frames with PTS less
than current output frame.

Make code implementation conditionally built for RaspberryPI because
OMX_IndexConfigAudioRenderingLatency seems to be a Broadcom extension.
On other targets the query position might not be accurate without
implementing _delay appropriatelly.
Provides omxanalogaudiosink and omxhdmiaudiosink elements on
the Raspberry PI.
- omxanalogaudiosink is capable to render raw mono or stereo audio
through the jack output.
- omxhdmiaudiosink is capable to render raw audio up to 8 channels
and transmit ac3/dts(IEC 61937) through the HDMI output.
- sinks provide a clock derived from rendered samples
- sinks support the GstStreamVolume interface by implementing
the volume and mute properties.

Previously when using gst EGLImage allocator the caps was
video/x-raw, format=RGBA instead of
video/x-raw(memory:EGLImage), format=RGBA

feature is not in the caps.

We have to return the buffers back to the pool in when stopping to
not mess with the GstBufferPool accounting.

When using GstOMXBufferPool on an output port, it internally uses
a GPtrArray to manage the GstBuffers instead of the default queue
from the GstBufferPool base class.
In this case GstBufferPool::default_free_buffer is not called when
the pool is stopped. Because the queue is empty. So explicitely
call gst_omx_buffer_pool_free_buffer on each buffer contained in
the GPtrArray.

Fix printf formats again, so that gst-omx compiles warning-
free on the Raspberry Pi as well. Unfortunately OMX_UINT32
maybe be typedefed to uint32_t or unsigned long, which
doesn't work well with our debugging printf format strings,
so just use %u for those and cast to guint.
