Was failing for release versions with
meson.build:414:10: ERROR: Can not set values on configuration object that has been used.
Caused by !69, but CI didn't notice at the time because it was set to a git version.
This hack tries to pass as much information as possible from caps to the
decoder before it receives any buffer. These information can be used by
the OMX decoder to, for example, pre-allocate its internal buffers
before starting to decode and so reduce its initial latency.
This mechanism is currently supported by the zynqultrascaleplus decoder.

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.
