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.

gst_omx_audio_enc_open will only update GstOMXAudioEnc->port->port_def.
Note that the component is reopen only if the flag

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
the raspbery pi. Instead it uses a custom extension to define the I
frame period.

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.
