4.1.2. ARM Multimedia Users Guide

Overview


Multimedia codecs on ARM based platforms could be optimised for better performance using the tightly coupled **Neon** co-processor. Neon architecture works with its own independent pipeline and register file. Neon technology is a 128 bit SIMD architecture extension for ARM Cortex-A series processors. It is designed to provide acceleration for multimedia applications.

Supported Platforms

  • AM37x

  • Beagleboard-xM

  • AM35x

  • AM335x EVM

  • AM437x GP EVM

  • AM57xx GP EVM

Multimedia on AM57xx Processor

On AM57xx processor, ARM offloads H.264, VC1, MPEG-4, MPEG-2 and MJPEG codecs processing to IVA-HD hardware accelerator. Please refer to AM57xx Multimedia Training guide to learn more on AM57xx multimedia capabilities, demos, software stack, gstreamer plugins and pipelines. Also refer to AM57xx Graphics Display Getting Started Guide to learn on AM57xx graphics software architecture, demos, tools and display applications.

Multimedia on Cortex-A8

Cortex-A8 Features and Benefits

For additional details, please refer the **NEON - ARM website**.

SDK Example Applications

This application can be executed by selecting the “Multimedia” icon at the top-level matrix.

NOTE

The very first GStreamer launch takes some time to initialize outputs or set up decoders.


../_images/Main_screen.png

Codec portfolio

Processor SDK includes ARM based multimedia using opensource GPLv2+ FFmpeg/Libav codecs, the codec portfolio includes MPEG-4, H.264 for video in VGA/WQVGA/480p resolution and AAC codec for audio. Codec portforlio for Processor SDK on AM57xx device is listed here

The script file to launch multimedia demo detects the display enabled and accordingly decodes VGA or 480p video. In AM37x platform VGA clip is decoded when LCD is enabled and 480p is decoded when DVI out is enabled. Scripts in “Settings” menu can be used to switch between these two displays.

MPEG4 + AAC Decode

MPEG-4 + AAC Dec example application demonstrates use of MPEG-4 video and AAC audio codec as mentioned in the description page below.


../_images/Mpeg4aac.png

The multimedia pipeline is constructed using gst-launch, GStreamer elements such as qtdemux is used for demuxing AV content. Parsers are elements with single source pad and can be used to cut streams into buffers, they do not modify the data otherwise.

gst-launch-0.10 filesrc location=$filename ! qtdemux name=demux demux.audio_00 ! queue ! ffdec_aac ! alsasink sync=false demux.video_00 ! queue ! ffdec_mpeg4 ! ffmpegcolorspace ! fbdevsink device=/dev/fb0

“filename” is defined based on the selected display device which could be LCD of DVI.

MPEG4 Decode

MPEG-4 decode example application demonstrates use of MPEG-4 video codec as mentioned in the description page below.


../_images/Mpeg4.png 

gst-launch-0.10 filesrc location=$filename ! mpeg4videoparse ! ffdec_mpeg4 ! ffmpegcolorspace ! fbdevsink device=/dev/fb0

H.264 Decode

H.264 decode example application demonstrates use of H.264 video codec as mentioned in the description page below.


../_images/H264.png 

gst-launch-0.10 filesrc location=$filename ! h264parse ! ffdec_h264 ! ffmpegcolorspace ! fbdevsink device=/dev/fb0

AAC Decode

AAC decode example application demonstrates use of AAC video codec as mentioned in the description page below.


../_images/Aac.png 

gst-launch-0.10 filesrc location=$filename ! aacparse ! faad ! alsasink

Streaming

Audio/Video data can be streamed from a server using souphttpsrc. For example to stream audio content, if you set-up an apache server on your host machine you can stream the audio file HistoryOfTI.aac located in the files directory using the pipeline

gst-launch souphttpsrc location=http://<ip address>/files/HistoryOfTI.aac ! aacparse ! faad ! alsasink

Multimedia Peripheral Examples

Examples of how to use several different multimedia peripherals can be found on the ARM Multimedia Peripheral Examples page.


SDK Multimedia Framework

Multimedia framework for cortex-a8 SDK will leverage GStreamer multimedia stack with gst-ffmpeg plug-in’s to support GPLv2+ FFmpeg/libav library code.

../_images/SDKMMFwk.png

gst-launch is used to build and run basic multimedia pieplines to demonstrate audio/avideo decoding examples.

../_images/MMFwk.png

GStreamer

  • Multimedia processing library

  • Provides uniform framework across platforms

  • Includes parsing & A/V sync support

  • Modular with flexibility to add new functionality via plugins

  • Easy bindings to other frameworks

Some of the build dependencies for GStreamer are shown here:

Re-enabling Mp3 and Mpeg2 decode in the Processor SDK

Starting with version 05.05.01.00, mp3 and mpeg2 codecs are no longer distributed as part of the SDK. These plugins can be re-enabled by the end user through rebuilding the gst-plugins-ugly package. The following instructions have been tested with gst-plugins-ugly-0.10.19 which can be found at **gstreamer.freedesktop.org**. Note that these instructions will work for any of the gstreamer plugin packages found in the sdk.

  • Source environment-setup at the terminal

  • Navigate into the example-applications path under the SDK install directory

  • Extract the GStreamer plug-in source archive

  • Navigate into the folder that was created

  • On the command line type ./configure --host=arm-arago-linux-gnueabi --prefix=/usr

  • Notice that some components are not built because they have dependencies that are not part of our SDK

  • Run make to build the plugins.

  • Run make install DESTDIR=<PATH TO TARGET ROOT>

Introduction

This page is a landing page for the entire set of WLAN and Bluetooth Demos available for the WL127x. Many of the demos are platform-agnostic, others apply specifically to a single platform.

The WL127x’s dual mode 802.11 b/g/n and Bluetooth transceiver gives users a robust selection of applications. A list of some basic use cases preloaded on the EVMs can be seen below:


Senario

Description

Bluetooth A2DP profile

Play a *.wav music file from the EVM on a stereo headset

Bluetooth OPP profile

Send a *.jpg image from the EVM to a cellular phone via OPP profile

Bluetooth FTP profile

Sends a text file from the EVM to a PC via FTP profile

Wireless LAN ping

Connect to an Access Point and perform a ping test

Wireless LAN throughput

Test UDP downstream throughput using the iPerf tool

Web browsing through the WLAN

Browse the web over WLAN using a PC connected to the EVM Ethernet port

Bluetooth and WLAN coexistence

Play a *.wav music file from the EVM on a stereo headset while browsing the web over WLAN

Bluetooth Demos

Classic Bluetooth

Bluetooth Low-Energy (BLE)


WLAN Demos

First Time

If running the WLAN demos on an EVM for the first time, it is recommended that you first complete the two steps below:

  • Step 1: Calibration – Calibration is a one-time procedure, performed before any WLAN operation. Calibration is performed once after the board assembly, or in case the 12xx connectivity daughtercard or EVM are replaced (refer to Calibration Process).

You may refer to Linux Wireless Calibrator page for more instruction.

  • Step 2: MAC address settings - This is a one-time procedure, done after the calibration, and before any WLAN operation is performed (refer to: <modifying WLAN MAC address>)
