The Tizonia OpenMAX IL framework

Tizonia OpenMAX IL contains a number of modules/libraries:

Module Name	Description
libtizcore	The OpenMAX IL 1.2 Core
libtizonia	An OpenMAX IL 1.2 base component library
tizrmd	A D-Bus based Resource Manager deamon process
libtizrmproxy	A client library to talk to the RM process
libtizosal	A library of utilities and wrapped OS functions

Tizonia OpenMAX IL components

The following OpenMAX IL 1.2 components are currently present in the Tizonia repositories, under the tizcomps folder.

Working components (with varying levels of quality)

Component	OMX Name	Roles	Description
Binary File Reader	OMX.Aratelia.file_reader.binary	audio_reader.binary
		video_reader.binary
		image_reader.binary
		other_reader.binary
Binary File Writer	OMX.Aratelia.file_writer.binary	audio_writer.binary
		video_writer.binary
		image_writer.binary
		other_writer.binary
MP3 decoder	OMX.Aratelia.audio_decoder.mp3	audio_decoder.mp3	Based on libmad
MP3 encoder	OMX.Aratelia.audio_encoder.mp3	audio_encoder.mp3	Based on LAME
VP8 decoder	OMX.Aratelia.video_decoder.vp8	video_decoder.vp8	Based on libvpx
Audio renderer	OMX.Aratelia.audio_renderer.pcm	audio_renderer.pcm	Based on ALSA
Video renderer	OMX.Aratelia.iv_renderer.yuv.overlay	iv_renderer.yuv.overlay	Based on libsdl

Skeleton components

These are work in progress components that do not yet include a processing function implementation.

Component	OMX Name	Roles	Description
Webp encoder	OMX.Aratelia.image_encoder.webp	image_encoder.webp
Webp decoder	OMX.Aratelia.image_decoder.webp	image_decoder.webp
Vp8 encoder	OMX.Aratelia.video_encoder.vp8	video_encoder.vp8

Test components

Component	OMX Name	Roles	Description
Tizonia test component	OMX.Aratelia.tizonia.test_component	tizonia_test_component.role1	Test component to support libtizonia's unit tests
		tizonia_test_component.role2
IL Core test component	OMX.Aratelia.ilcore.test_component	default	Test component to support libtizcore's unit tests

Non-standard components

These are components that do not have a corresponding definition in the Standard Components section of the OpenMAX IL specification. Normally, OpenMAX IL extensions needed to build these components are found in the OMX_TizoniaExt.h header file.

Component	OMX Name	Roles	Description
Icecast-like HTTP Sink	OMX.Aratelia.ice_renderer.http	ice_renderer.http	Work in progress: This sink will be used to implement a simple http streaming server application

Example command-line apps

The examples directory contains a number of command-line programs that use the Tizonia OpenMAX IL Core and components.

tizplay

A simple player that can decode mp3s (TODO: and vp8 files) using deep tunneled OpenMAX IL components.

Tizonia OpenMAX IL player version 0.1.0

usage: tizplay [-l] [-r] [-c] [-v] [-d] <file_uri>
options:
	-l --list-components			Enumerate all OpenMAX IL components
	-r --roles-of-comp <component>		Display the roles found in <component>
	-c --comps-of-role <role>		Display the components that implement <role>
	-d --decode <file_uri>			Decode a mp3 or ivf (vp8) file
	-v --version				Display version info

Example:
	 tizplay -d ~/Music (decodes every supported file in the '~/Music' folder)
	    * Press [Ctrl-\] to skip to next song.
	    * Press [Ctrl-z] to suspend the playback (type 'fg' or 'bg' to resume).
	    * Press [Ctrl-c] to terminate the player.

tizcast

A simple streaming server application, ala icecast (TO BE DONE).
