What is?

IGEP gst framework it's based on TI DVSDK. It's modified version for provide all DSP essential packages and the gstreamer DSP plugin for use it in IGEP platforms.

Changes From 3.00.00

• Support linux kernel 2.6.35.13-3
  
• Update codec server to codecs-omap3530_4_02_00_00.
  
• Added MP3 codec (decode only).
  
• Added IGEP X-Loader.
  
• Prebuild binaries for DM3730 and OMAP3530 included.
  

Dependences

• ISEE Toolchain poky-eabi-glibc-i586-arm-toolchain-sdk-3.2.1.tar.bz2
  
• linux kernel 2.6.35.13-2 included with this package.
  
• Ubuntu 10.10
• Automake 1.7 and Libtool ( sudo apt-get install autoconf automake libtool )
• Gstreamer.
  
• SDK: alsa-dev_1.0.20-r1_armv7a.ipk (Now included inside the directory: tools/package).
  

Download

The package be available in the IGEPv2 download area.

01-ISEE_Products --> IGEPv2 --> SW_Tools_SDK --> igep_gst --> igep-dsp-gst-framework-3_10_10.tar.bz2

Download the package and uncompress this package as normal user in your desired directory (don't use sudo command for decompress this file)

How to Build

You should edit the file Rules.make and update package path and toolchain path.

Rules.make

Your igep-gst directory path:

WORKSPACE=<YOUR_USER_PATH>

DVSDK_INSTALL_DIR=$(WORKSPACE)/igep-dsp-gst-framework/igep-dsp-gst-framework-3_10_10

Your toolchain directory path:

CSTOOL_DIR=/usr/local/poky/eabi-glibc

CSTOOL_PREFIX=$(CSTOOL_DIR)/bin/arm-none-linux-gnueabi-

Now the kernel it's included with this package you don't need to change anything related to the kernel.

Select your right processor:

PLATFORM=o3530 (OMAP3530)

PLATFORM=dm3730 (DM3730)

Build & Clean

Build the framework:

cd /home/<YOUR_USER_PATH>/Projects/myigep/workspace/igep-dsp-gst-framework/igep-dsp-gst-framework-3_10_00
make

Clean the framework

cd /home/<YOUR_USER_PATH>/Projects/myigep/workspace/igep-dsp-gst-framework/igep-dsp-gst-framework-3_10_00
make clean

Build & Clean Manually

Build the framework:

cd /home/<YOUR_USER_PATH>/Projects/myigep/workspace/igep-dsp-gst-framework/igep-dsp-gst-framework-3_10_00
make linux
make dsplink
make lpm
make cmem
make sdma
make codecs
make c6accel
make c6run
make dmai
make gst_ti

Clean the framework:

cd /home/<YOUR_USER_PATH>/Projects/myigep/workspace/igep-dsp-gst-framework/igep-dsp-gst-framework-3_10_00
make linux_clean
make dsplink_clean
make lpm_clean
make cmem_clean
make sdma_clean
make codecs_clean
make c6accel_clean
make c6run_clean
make dmai_clean
make gst_ti_clean

Install

After build the framework you must install all build packages inside the target directory using below command.

make install

Inside the target directory you've two new directories:

dm3730-binaries (modules, kernel ... for DM3730)

omap3530-binaries (modules, kernel ... for OMAP3530)

Copy target directory to your board as:

cd target
scp -r dm3730-binaries <remote_user>@<IGEP IP>:/home/<your_desired_directory>
scp -r scripts <remote_user>@<IGEP IP>:/home/<your_desired_directory>

Also included you've the IGEP Xloader and the configuration file.

Enter inside your IGEP board and go to gstreamer directory normally inside /usr/lib/gstreamer-0.10 and create two symbolic links from this directory to your files:

cd /usr/lib/gstreamer-0.10

ln -s /home/<your_desired_directory>/cs.x64P

ln -s /home/<your_desired_directory>/libgstticodecplugin.so

or copy the files directly as inside target directory location.
