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 MPEG4 and H264 720P Video Encoder.
  • 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 is available at the Official ISEE site, at the IGEPv2 download area.

http://isee.biz/component/zoo/item/igep-dsp-gst-framework

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_10
make

Clean the framework

cd /home/<YOUR_USER_PATH>/Projects/myigep/workspace/igep-dsp-gst-framework/igep-dsp-gst-framework-3_10_10
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_10
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_10
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.

Play with it

[IMPORTANT] Some modules requires root privileges account.

Normally in this example we will use 2 frame buffers and we will use the fb2 for playing the videos.

We only need load the modules one time, we provide in the target/scripts directory some useful scripts. You should load the modules using the load-modules.sh script (just remember execute it as root).

After load all modules then you should configure the fb1, it's suggested use the fb1-16M-settings.sh script after that the video image can be black or with random pixels (just it's normal) now you've the fb1 and fb0 running.

fb1 it's on TOP and fb0 it's under fb1, it means that if you don't enable the transparency it's not possible see the fb0.

Now, you're ready for play some nice video using gstreamer, you can use these pipelines:

This is for play a avi file and uses the omapdmaifbsink. 

gst-launch-0.10 -v filesrc location=$1 ! avidemux name=demux  demux.audio_00 ! queue max-size-buffers=8000 max-size-time=0 max-size-bytes=0 \
! TIAuddec1 ! alsasink demux.video_00 ! queue max-size-buffers=2 max-size-time=0 max-size-bytes=0 ! TIViddec2 engineName=codecServer ! omapdmaifbsink

Or You can use this other for play a mp4 file it uses a TIDmaiVideoSink.

gst-launch-0.10 -v filesrc location=$1 ! qtdemux name=demux  demux.audio_00 ! queue max-size-buffers=8000 max-size-time=0 max-size-bytes=0 \
! TIAuddec1 ! alsasink demux.video_00 ! queue max-size-buffers=2 max-size-time=0 max-size-bytes=0 ! TIViddec2 engineName=codecServer \
! queue ! TIDmaiVideoSink displayStd=fbdev displayDevice=/dev/fb1 accelFrameCopy=TRUE contiguousInputFrame=1
