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 3.10.00
- Support linux kernel 2.6.35.13-2
- ISEE kernel 2.6.35.13-2
- Update codec server to codecs-omap3530_4_02_00_00.
- Added MP3 codec (decode).
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 )
- SDK: alsa-dev_1.0.20-r1_armv7a.ipk (Now included inside the directory: tools/package).<span style="color: rgb(0, 0, 0);" />
Download
The package be available in the IGEPv2 download area.

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=/home/<YOUR_USER_PATH>/Projects/myigep/workspace/igep-dsp-gst-framework/igep-dsp-gst-framework-3_10_00
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.
Build
Follow next steps:
cd '''<span style="color: rgb(255, 0, 0);">/home/<YOUR_USER_PATH>/Projects/myigep/workspace/igep-dsp-gst-framework/igep-dsp-gst-framework-3_10_00 </span>''''''<span style="color: rgb(255, 0, 0);">make</span>''''''<span style="color: rgb(255, 0, 0);"> </span>'''
You have two options: build all or every package individually.
a) All packages
make
b) One package
make <package_name>
make dmai make gst make dsplink ...
For clean the build you should execute:
make clean
or
make <package_name>_clean
such:
make dmai_clean make dsplink_clean make gst_clean
Build Manually
$ make linux_kernel dsplink cmem lpm sdma codecs dmai gst_ti opengldemos
Install
Copy the "target" directory inside your IGEP board ( rcp * jdoe@192.168.2.1: )
Inside IGEPv2 board you should copy the gst plugin inside the plugins directory, normally inside /usr/lib/gstreamer-0.10
We included some files for configure, load and unload the kernel modules as loadmodules.sh and unloadmodules.sh
You should call the loadmodules.sh script before you can execute gstreamer.
Uboot Setup
You should configure the max kernel memory to 430MBytes for do it you should pass the variable mem=430M to the kernel.
This is a suggested configuration: bootargs-base=mem=430M console=ttyS2,115200n8 console=tty0 omapfb.mode=dvi:1280x720MR-16@60 vram=32M omapfb.vram=0:8M,1:16M,2:8M
Issues detected in this version
- make clean (dsplink) not work properly and it's necessary to do a make dsplink_clean for ensure all it's compiled correctly and remove the kernel modules from the dsplink directory.
- gstreamer plugin directory "gstreamer-ti_svnr884/src/gstticodecplugin_dm3730" must be removed the first installation time (manually).
- Typo in Makefile. "linaro_linux" must be changed to "linux_linaro". Otherwise "make linux_kernel" fails.
