Building the Gstreamer for DM81xx processor

Hi Salih

You need to install build pakages like bison ,flex, libtool etc. so please update pakages before building gstreamer.

sudo apt-get install libtool

sudo apt-get install bison

sudo apt-get install flex

Hi Santhosh,

Thanks. But, after that I am getting the below error while compiling. How can I solve this error. Please give me the solution for the below error.

arm-none-linux-gnueabi-gcc is unable to create an executable file.
C compiler test failed.

If you think configure made a mistake, make sure you are using the latest
version from SVN.  If the latest version fails, report the problem to the
ffmpeg-user@mplayerhq.hu mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.err" produced by configure as this will help
solving the problem.
config.status: error: Failed to configure embedded FFmpeg tree
make[3]: *** [ffmpeg.configure] Error 1

Thanks in advance.

Hi Salih,

Let me know which EZSDK version are you using.

Please check below steps you followed.

cd to EZSDK install directory and do

make all

after that go to gstreamer directory and do

make clean

make all install VERBOSE=true

Please refer README.txt present in gstreamer  root directory for more information.

Hi Santhosh,

I am using EZSDK dm816x-evm_5_01_01_80. And also I am following the same procedure whatever you said above. But the error occurring. Please let me know how to solve this error.

I am also downloaded my source code from the below link. Inside I downloaded the whole directory gstreamer_ti_dm81xx.

https://gstreamer.ti.com/gf/project/gstreamer_ti/scmsvn/?action=browse&path=%2Ftrunk%2F

I can't able to dowload via SVN commands. So I downloaded each files seperately. Please give me the solution to solve this.

Thanks in advance.

Hi Santhosh 

I dowloaded the lateset version what you told before(ti-ezsdk_dm816x-evm_5_03_01_15).

But while compiling I am getting this below error.

Hi Salih,

are compiling gstreamer or EZSDK?

let me know which toolchain are you using  . extract target file system before compiling EZSDK by executing ./setup.sh present in EZSDK install directory.   

Regards

Santosh

Hi Santhosh,

I am compiling the Gstreamer. But while running ./setup.sh I am getting this below error.

This step will extract the target filesystem to /root/targetfs

Note! This command requires you to have administrator priviliges (sudo access)
on your host.
Press return to continue

gzip: stdin: unexpected end of file
tar: Unexpected EOF in archive
tar: Unexpected EOF in archive
tar: Error is not recoverable: exiting now
Failed setup, aborting..

Please let me give the solution for the above error.

Thanks in advance.

Hi Salih,

Look your EZSDK is not installed properly. we need around 10GB space.

make sure the your EZSDK is downloaded completely . check md5sum provided in release page with your downloaded file.

Regards

Santosh Avati

Hi Santhosh,

I had around 10GB space. So I installed that package successfully.

But while compiling the EZSDK package I am getting the below error.

Also while compiling the gstreamer_ti81xx I am getting the same error  still. The error is given below.

If you think configure made a mistake, make sure you are using the latest

Include the log file "config.err" produced by configure as this will help
solving the problem.

Also I don't know where I have to the find md5sum. Please give me the solution for this error. 

I am struggling with this gstreamer compiling for more than 20 days. 

Please help me to solve this error.

Thanks in advance.

Salih

Hi Salih,

Don't compile gstreamer before EZSDK.

Logs are corp. please attach the logs in a text file.

MD5sum is present on release page only. search for ms5sum.txt on page

http://software-dl.ti.com/dsps/dsps_public_sw/ezsdk/latest/index_FDS.html.

Can you attach yours Rules.make file present in EZSDK install directory

Hi Santhosh,

I compiled the Gstreamer sucessfully. I am very happy to say you. But I don't how to run the video in my target. Which commands I need to give if I want to run video in my LCD or HDMI. Please help me to run this. I tried with some commands like given below:

gst-launch -v filesrc location=seas.mov ! qtdemux name=demux demux.audio_00 ! queue ! faad ! alsasink demux.video_00 ! queue !  

nal2bytestream_h264  !  omx_h264dec ! omx_scaler ! omx_ctrl display-mode=OMX_DC_MODE_1080P_60  ! gstperf ! omx_videosink

But I am getting below error message.

ERROR: pipeline could not be constructed: no element "filesrc".

how can I run this. Please suggest me any solution.

Thanks in advance.

Salih

Hi Salih,

if your gstreamer installed path is /opt/gstreamer

execute below commands on target  before playback

/etc/init.d/matrix-gui-e stop

amixer set PCM 127 

export GST_REGISTRY=/tmp/gst_registry.bin
export LD_LIBRARY_PATH=/opt/gstreamer/lib
export GST_PLUGIN_PATH=/opt/gstreamer/lib/gstreamer-0.10
export PATH=/opt/gstreamer/bin:$PATH
export GST_PLUGIN_SCANNER=/opt/gstreamer/libexec/gstreamer-0.10/gst-plugin-scanner
cd /lib/modules/2.6.37/kernel/drivers/media/video/ti81xx/
insmod ti81xxvo.ko

if your installed path other that /opt/gstreamer, than replace with your installed path

Regards

Santosh

Hi santhosh,

But I am not getting this binary any where gst_registry.bin.

I don't why this binary is not creating.

I set the below paths in my Makefile.common file as given below:

TARGET_ROOT_DIR      = /home/ansaris/targetfs
GSTREAMER_DIR        = /usr
GST_TI_PLATFORM      = dm816x
EZSDK_INSTALL_DIR    = /home/ansaris/ti-ezsdk_dm816x-evm_5_03_01_15

But I don't know why this gst_registry.bin is not creating. Please suggest me any solution for this.

Thanks in advance,

Regards,

Salih

Hi Salih

Its ok if you don't have it gst_registry.bin.

from your setting gstreamer installed directory is /usr. so please export below PATH in target.

execute below command on target for /usr

/etc/init.d/matrix-gui-e stop
amixer set PCM 127
export GST_REGISTRY=/tmp/gst_registry.bin
export LD_LIBRARY_PATH=/usr/lib
export GST_PLUGIN_PATH=/usr/lib/gstreamer-0.10
export PATH=/usr/bin:$PATH
export GST_PLUGIN_SCANNER=/usr/libexec/gstreamer-0.10/gst-plugin-scanner
cd /lib/modules/2.6.37/kernel/drivers/media/video/ti81xx/
insmod ti81xxvo.ko

Regards

santosh

Hi Santhosh,

While executing below command, I am getting below error. I don't know why I am getting this. Please suggest the solution for this.

root@dm816x-evm:~# amixer set PCM 127
amixer: Mixer attach default error: No such file or directory

I installed the module after that how can I run the video using gstreamer. Which commands I should use. Still I am struggling. Please give the solution.

Thanks in advance,

Salih
