DMAI GStreamer Plug-In Getting Started Guide

From Texas Instruments Wiki
Jump to: navigation, search

Important Note:

The software discussed on this site is available for download, but is no longer being actively developed. This wiki is in maintenance mode and the software is supported on Multimedia Codecs E2E forum


This section collects information from a variety of places to simplify obtaining, building, and running a gst-ti-dmai gstreamer pipeline. Information on the full documentation is provided, along with greatly simplified steps. You can access the existing detailed instructions contained in the README.TXT file. Overview

The major steps to go from nothing to hardware accelerated GStreamer running on your target hardware include:

  • Configuring host PC
  • Getting the target software
  • Installing target software
  • Building the libraries and tools
  • Transferring code to the target hardware
  • Running test pipelines
  • Creating your first GStreamer application
  • Resolving common problems

Common steps are described below, with each processor having its own wiki page. Please enhance the wiki as you are following these steps to make it easier for the next person.

Contents

Configuring host PC[edit]

The software for the target device is cross-compiled, meaning you run the compiler on a host computer (typically x86 based host processor) with the compiler generating code for the target hardware (ARM target processor). The host PC configuration steps install the necessary tools to allow you to retrieve the source code, build the target applications and libraries, and get the needed components on the target hardware so you can run hardware accelerated GStreamer.

Each Linux distribution has a unique way installing the packages needed to use the host computer for cross-compilation. If your Linux distribution isn't listed below, please add it. 

*  RHEL4 host system
*  Ubuntu 9.04 host system


Cross-compile toolchain[edit]

Choose the appropriate toolchain based on your target processor:

Target processor Toolchain
DM355 CS 2009q1 ARM GNU/Linux for host iA32 GNU/Linux
DM365 CS 2009q1 ARM GNU/Linux for host iA32 GNU/Linux
DM6446 MV arm_v5t_le-
DM6467 MV arm_v5t_le-
DM6467T CS 2009q1 ARM GNU/Linux for host iA32 GNU/Linux
OMAP35xx CS 2008q1 ARM GNU/Linux for host iA32 GNU/Linux

MV toolchain installation[edit]

If your target hardware build requires the MV toolchain, install as follows: 

chmod ugo+x mvl_5_0_0801921_demo_sys_setuplinux.bin 
chmod ugo+rwx /opt                                              # this might make some system administrators nervous
./mvl_5_0_0801921_demo_sys_setuplinux.bin --mode console --prefix /opt/mv_pro_5.0
cd /opt/mv_pro_5.0
sudo tar -xzf mvltools5_0_0801921_update.tar.gz                 # super user privileges needed for device files in the target file system


CS 2008q1 toolchain installation[edit]

Detailed instructions at GSG: OMAP35x DVEVM Software Setup#Installing_the_toolchain 

mkdir -p $HOME/toolchain
cd $HOME/toolchain
tar -jxf /opt/images/arm-2008q1-126-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2

CS 2009q1 toolchain installation[edit]

Detailed instructions at Installing CodeSourcery Toolchain 

cd /opt
sudo tar -xjf /tmp/arm-2009q1-203-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2

DMAI GStreamer source code[edit]

Download the latest released gst-dmai source code. You need to unpack the gst-dmai source code tarball in the correct directory: 

cd $HOME
tar -xzf /tmp/gst-ti-plugin-full-*.tar.gz

if you want to use the latest (not released) gst-dmai source code: 

cd $HOME
svn checkout --username anonymous --password "" https://gstreamer.ti.com/svn/gstreamer_ti/trunk/gstreamer_ti gstreamer_ti

If you use the code from SVN, then you need to use the directory name $HOME/gstreamer_ti instead of $HOME/gst-ti-plugin-full-*.

MV toolchain pkg-config update[edit]

If you are using the MV toolchain, you need to update your pkg-config application. 

cd $HOME/gst-ti-plugin-full-1.01.00/opensource_build/host_tools
tar -xzf pkgconfig-0.18.tar.gz
cd pkgconfig-0.18
./configure --prefix=/opt/mv_pro_5.0/montavista/pro  # the version in the toolchain is too old, so we replace it
make
sudo rm -f /opt/mv_pro_5.0/montavista/pro/bin/pkg-config
sudo make install


Host Directory Structure[edit]

Obtaining the software[edit]

Software from TI website[edit]

Each target processor requires software that is unique for that hardware.

The toolchain, DVSDK, and related software is downloaded from the TI website. For the links in the tables below to work, you must first log into the TI website. In general, you can start at the current download page and browse around to find all the packages listed below.


Target processor specific DVSDK and related software[edit]

The target processor specific source code consists of several components and is packaged together into a DVSDK - Digital Video Software Development Kit. Each target processor may use a different DVSDK version. If you are already logged into the TI website, you can click on the DVSDK link in the table below to go to the appropriate DVSDK download link.

In addition, download the related software.

Building the libraries and tools[edit]

There is a detailed Getting Started Guide that is part of the DVSDK. The steps described below are simplifed version of the more complete steps listed in the guide. For the full DVSDK instructions, refer to the HTML files in the DVSDK directory and the docs directory inside the DVSDK directory.


Building DM355 kernel, DVSDK, and GStreamer software (DVSDK 3.10.00.19)[edit]

The target file system includes a pre-built DVSDK, so there is no need to build the DVSDK. There is also a pre-built kernel image, so the Linux kernel doesn't need to be built either. Instructions on how to build the DVSDK and kernel are included for completeness.

Building DM6467T kernel, DVSDK, and GStreamer software (DVSDK 3.10.00.19)[edit]

The target file system includes a pre-built DVSDK, so there is no need to build the DVSDK. There is also a pre-built kernel image, so the Linux kernel doesn't need to be built either. Instructions on how to build the DVSDK and kernel are included for completeness. 

# Build kernel (optional, pre-built kernel is available for download)

Running test pipelines[edit]

There are many Example GStreamer Pipelines for you to try. If you come up with some clever ones of your own, please add the pipelines to the wiki.

Creating your first GStreamer application[edit]

To be written

Resolving known problems[edit]

../libtool: line 763: X--tag=CC: command not found[edit]

The libtool on your host computer is causing the problem (using $(echo) when it is not defined). Either install an older libtool version (1.5.26) or define the echo environment variable. 

export echo=echo


../libtool: eval: line 4174: syntax error near unexpected token `|[edit]

This error happens when generating symbol list for `libgstticodecplugin.la'.

This error may occur when building with releases older than 1.01. The problem was fixed in SVN trunk@275.

In the top level GStreamer TI Makefile.common file (e.g. Makefile.common in gstreamer_ti or gst-ti-plugin-full-1.00.02), change CC_CONFIGURE_OPTS from: 

CC_CONFIGURE_OPTS        = --build=i686-linux --host=arm-linux \
                           --prefix=$(TARGET_GSTREAMER_DIR)

to 

CC_CONFIGURE_OPTS        = --build=i686-linux --host=arm-linux \
                           --prefix=$(TARGET_GSTREAMER_DIR)    \
                           NM=$(MVTOOL_PREFIX)nm

v4l2src build error - V4L2_STD_525P_60 undefined[edit]

See V4L2_STD_525P_60 undefined error for details.

In the gstreamer_ti/opensource_build/Packages.make, add to the end of the following like as shown: 

PACKAGE_plugins_good_CONFIGURE_OPTS      = $(USE_V4L2SRC_WORKAROUND) --disable-x

If the error persists, verify you have a trailing slash in the paths specified in the DSDK Rules.make file.

error: asm/arch/imp_resizer.h: No such file or directory[edit]

Something is amiss with your kernel. If you issued a make command like 

make ... LINUXKERNEL_INSTALL_DIR= ...

then first check that the Linux kernel is at the specified location. For instance, if you have 

make DVSDK_INSTALL_DIR=$HOME/dvsdk_2_10_01_18 TARGET_ROOT_DIR=$HOME/workdir/filesys CROSS_COMPILER=MVL_5_0 \
     LINUXKERNEL_INSTALL_DIR=$HOME/workdir/lsp/ti-davinci/linux-2.6.18_pro500 VERBOSE=1 PLATFORM=dm365 all install

then try 

ls -ld $HOME/workdir/lsp/ti-davinci/linux-2.6.18_pro500

If you get an error, that means the kernel source is not where you think it is located.

If you don't get an error, then verify the symbolic link for the architecture directory was properly created. 

ls -ld $HOME/workdir/lsp/ti-davinci/linux-2.6.18_pro500/include/asm/arch

If you get an error, that means you didn't build the kernel correctly.

"mkimage" command not found - U-Boot images will not be built[edit]

This means that you don't have the mkimage package installed at your host machine 

 sudo apt-get install uboot-mkimage

and try building again

configure:error:c++ preprocessor "/lib/cpp" fails sanity check[edit]

This means that you don't have the build-essential package installed at your host machine 

 sudo apt-get install build-essential

and try building again

/bin/sh: 1: not found[edit]

There are different variations of the error message displayed. What the error has in common is an unexpected characters in injected before a shell command.

The problem is caused by XDC not liking a period '.' in directory names. Rename the directory and then do a 

 make clean

and try again.
