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.

SDK Example Applications

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


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


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.


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.


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.


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.


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


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.

OProfile is a common profiling tool used on Linux platforms, a kernel driver and a user daemon is used to collect samples of data. This tool can be used to profile a huge variety of system-level statistics. Please refer OProfile for additional details.

Listed below are the profiling results of Mpeg4 + AAC in VGA resolution at 300MHz and 1GHz via NFS server. Profiling results are obtained from the serial terminal.

In order to profile the multimedia application kernel has to be compiled with oprofile enabled. Followed by this, opcontrol has to be enabled for the first time

root@am37x-evm:~# opcontrol --vmlinux=/boot/vmlinux-`uname -r`

Setopp power/clocks application can be used to scale the clock settings, the example below shows the settings for opp2, similarly clock can be set to 1GHz using the application.

Re-enabling Mp3 and Mpeg2 decode in the Processor SDK

Starting with version, 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 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>
