Compiling GStreamer 1.0 for ARM

Hello,

Could you search for libgstreamer1.0
I am asking because gst/gst.h is provided by this lib.


You could check this :

"To compile the helloworld example, use:
gcc -Wall helloworld.c -o helloworld $(pkg-config --cflags
--libs gstreamer-1.0)
. GStreamer makes use of
pkg-config
to get compiler and linker flags needed to
compile this application.
If you’re running a non-standard installation (ie. you’ve i
nstalled GStreamer from source yourself instead
of using pre-built packages), make sure the
PKG_CONFIG_PATH
environment variable is set to the correct
location (
$libdir/pkgconfig
).
In the unlikely case that you are using an uninstalled GStrea
mer setup (ie. gst-uninstalled), you will need
to use libtool to build the hello world program, like this:
libtool --mode=link gcc -Wall helloworld.c -o
helloworld $(pkg-config --cflags --libs gstreamer-1.0"


Are you able to build it for PC? Or it is failing for both ( PC and Arm )?

Hello Margarita,

I get this error.

Package gstreamer-1.0 was not found in the pkg-config search path.

Perhaps you should add the directory containing `gstreamer-1.0.pc'

to the PKG_CONFIG_PATH environment variable

No package 'gstreamer-1.0' found

libtool: link: gcc -Wall My_Gst_app.c -o gstapppc

My_Gst_app.c:2:20: fatal error: gst/gst.h: No such file or directory

compilation terminated.

 

I couldn't get the code compiled for both PC and arm. 

My PKG_CONFIG_PATH path is /usr/lib/pkgconfig

kindly help me.

Thanks

Hello,

For ARM have you cross-compiled gstreamer Or does the GLSDK have cross-complied libraries for it so that you can include in your include paths ?
For your PC have you installed gstreamer ? Which OS are you using ?

Hi Prabhakar,

GLSDK has Cross Compiled Packages. So, I can compile for arm from my PC and use the executable file on the Board directly.
For PC, I have nstalled gstreamer using "sudo apt-get install" method.
I am using Ubuntu 12.04 LTS.

Hello,

If GLSDK has compiled the gstreamer and has all the libraries & includes file, can you tell what location its is ? Does glsdk have pc files for gstreamer library ?

What is the output of the following command:
'pkg-config --libs --cflags gstreamer-1.0 gstreamer-app-1.0'

To install gstreamer-1.0 on 12.04

hit the following commands,

sudo apt-get install ubuntu-restricted-extras

//backports from gstreamer developer ppa

sudo add-apt-repository ppa:gstreamer-developers/ppa
sudo apt-get update

//install the base packages and plugins for gstreamer
sudo apt-get install gstreamer1.0*

Hello Prabhakar,

When I try to install GStreamer 1.0, I get this error!!!

I just mentioned about the GLSDK compiled GStreamer, Because when I use the processor (with bootable SD Card), I could run gst-launch1.0 or gst-inspect-1.0. And also, I prepared a pipeline which worked fine.

Hello,

To install gstreamer-1.0 on your machine (ubuntu 12.04) hit the following 4 commands in order:

1: sudo apt-get install ubuntu-restricted-extras

2: sudo add-apt-repository ppa:gstreamer-developers/ppa

3: sudo apt-get update

4: sudo apt-get install gstreamer1.0*

If the above still fails please provide the logs of all the commands.

Shylesh I just mentioned about the GLSDK compiled GStreamer, Because when I use the processor (with bootable SD Card), I could run gst-launch1.0 or gst-inspect-1.0. And also, I prepared a pipeline which worked fine.

This means that the filesystem in the bootable sd card  has the cross compiled executables and binaries.

Hi Prabhakar,

I couldn't install Gstreamer 1.0, in spite of having a proper net access for the installation.

I will attach the log files here.

And, Yes. The Bootable SD card is capable of processing the GStreamer files, as it has the needy Binaries and Executables.

Hello,

Could you check in you GLSDK installation dir about :
gstreamer-app-1.0.pc for example.

Notice that this is .pc file.

I am not sure about GLSDK but you should :

export PKG_CONFIG_PATH=$SDK_PATH/$TARGET_SYS/usr/lib/pkgconfig

in pkgconfig folder you have .pc files.

BR
Margarita

Hi Margarita,

I checked my GLSDK installed directory and the bootable SD card.
It doesn't contain a file called gstreamer-app-1.0.pc

Hello,

Either you need to update you operating system to 14.04+ which has gstreamer-1.0 support by default Or manually download source compile n install in you OS.

--Prabhakar Lad

Hi Prabhakar,

I see that my GLSDK (7.03) works only with Ubuntu 12.04. Can you let me know, if 14.04 supports GLSDK??

I also tried compiling and installing the GStreamer 1.0 manually. But, I get an error like this " configure: Requested 'glib-2.0 >= 2.40' but version of GLib Uninstalled is 2.32.4"

 

Best Regards,

Shylesh S

Hello,

I am not sure if glsdk will work on 14.04, as the wiki says 12.04.
Alternatively you can just cross compile your gstreamer application on a different machine which has ubuntu 14.04 + and gstreamer-1.0
all you just need to copy your cross-compiler to that machine.

Thank you very much Prabhakar! I will get back If I need more clarifications!

Hello Prabhakar/Margarita,

I have now installed GSTREAMER from the source files. I followed the link "" to install. But, used the following commands to make and install.

./configure --host=arm-linux-gnueabihf --prefix=/usr/arm-linux-gnueabi/usr/local/ --disable-loadsave --disable-gtk-doc --disable-examples --includedir=/usr/arm-linux-gnueabi/usr/include/ --libdir=/usr/arm-linux-gnueabi/usr/local/lib/ --exec-prefix=/usr/arm-linux-gnueabi/usr/local/

make -j4

make install

I have also exported the PKG_CONFIG_PATH. (export PKG_CONFIG_PATH=/usr/arm-linux-gnueabi/usr/local/lib/pkgconfig/)
Now, I find no errors which expect some missing .so files. But I face some other issue. When I try to compile my code using  arm-linux-gnueabi-gcc -Wall My_Gst_app.c -o gstapparm  `pkg-config --cflags --libs gstreamer-1.0 gstreamer-app-1.0` , I get the following error.

root@shylesh:/home/shylesh/Standalones/Gstreamer_basic# arm-linux-gnueabi-gcc -Wall My_Gst_app.c -o gstapparm  `pkg-config --cflags --libs gstreamer-1.0 gstreamer-app-1.0`

I see that the .so and .pc files are all available. But, I get FILE FORMAT NOT RECOGNIZED error.

I have not yet tried compiling using Ubuntu 14.04. Should I try compiling using 14.04 OS also??

Kindly help me!

Best Regards,

Shylesh S

Hi,
I have also tried this on Ubuntu 14.04. The same happens with this also. I face the same errors. I have also tried downloading the source files and compiling it, as I’ve mentioned on the previous post.

Can you kindly, help me in finding the cross compiled .so files for arm that are readily available on the web for Gstreamer 1.0?? Coz, I could find the .so files for arm that are available.
Or, If not possible.. Please let me know regarding the procedure of cross compiling the Gstreamer Application for the ARM.

Thanks a lot.
Shylesh S

Hello,

When you have cross-compiled glib & gstreamer, just use -I and -L option of gcc and compile.

For example:

arm-linux-gnueabi-gcc -Wall My_Gst_app.c -o gstapparm -I <path where include files for gst reamer are present> -L <path where gstreamer libraries are present> -lgstapp.so.... (similar for glib)

Hi,

Great good to hear.

I usually use buildgear [1], to build my own sdk
