The OMX spec doesn't support HEVC but the OMX stack of the
zynqultrascaleplus adds it as a custom extension.
It uses the same API as the one of Android's OMX stack.
I used the H264 encoder code as a template.

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.

Install libomxil-bellagio0 and make sure mesa has been built with
--enable-omx. Check there is /usr/lib/libomxil-bellagio0/libomx_mesa.so
then run omxregister-bellagio to regenerate $XDG_DATA_HOME/.omxregister
Then omxh264dec and omxmpeg2dec should load.

MP3 Software decoder (libmad based) but useful for testing
and to compare with other targets.
GST_OMX_CONFIG_DIR=$HOME/gst/master/gst-omx/config/bellagio/ \
gst-launch-1.0 filesrc location=mpthreetest.mp3 ! id3demux ! \
mpegaudioparse ! omxmp3dec ! audioconvert ! pulsesink
Didn't add 'local' in core-name path compared to other components
in that same gstomx.conf file because OMX.st.audio_decoder.mp3.mad
comes with the Ubuntu package 'libomxil-bellagio0-components-mad'.
All other components listed in this gstomx.conf for Bellagio, are
not provided by any Ubuntu packages. It could explain the 'local',
i.e. requiring to build them from source.
dpkg -L libomxil-bellagio0
/usr/lib/libomxil-bellagio.so.0

egl_render seems to have a bug and signals EOS before it has finished
pushing out all data; this hack simply makes acquire_buffer() wait
a bit more before signalling EOS, in case egl_render decides to spit
out some more data.

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.
