[gst-devel] How to register dfbvideosink

[Wolfson, Alexander]

Hi,

I still have problems with dfbvideosink.

I have the following output when I run 

#gst-launch filesrc location=TrainingWithHumor_H264.mp4 ! decodebin !
dfbvideosink


(!) Direct/Modules: Could not open module directory
`/localdisk/integration/LRP_ZYLONITE_P_EB5/src/gstreamer/gst-deps/lib/di
rectfb-0.9.24/systems'!
    --> No such file or directory
(!) DirectFB/core/system: No system found!

My LD_LIBRARY_PATH
/opt/Qtopia/lib:/usr/local/lib:/usr/lib:/lib:/usr/lib/ipp:/lib/lib:/usr/
gst/lib:/usr/gst-deps/lib
seems to be correct.


What am I missing? How the directory for modules suppose to be
specified?
Can you give an example of working gstreamerv command line to play
video, preferable h264?

I included the log and the build script I used into the message.

Thanks a lot for your previous help.
I hope one last step left :)

Then it sits here forever.

I use the following script to build plugins:

#pushd gstreamer-0.10.0

echo PKG_CONFIG_PATH=$PKG_CONFIG_PATH

export CC=arm-linux-gcc

export GST_PLUGIN_LDFLAGS="-lgstbase-0.10 -lgstcontroller-0.10"

Hi Stefan,

Thanks a lot!
It was fast. The new log output helped to solve the problem.
As you suspected 2 libraries directfb and fusion were missing on the
target.
At least plugin is registered now.

Thanks again,

Alex

They are added automatically. This error means gstreamer is trying to
add it again and again, but still it fails to load. As I said the most
liekly case is a missing symbol. But then this information should be
next there in the log. Does the log say abything else. Can you try to
run again using:
GST_DEBUG="GST_PLUGIN_LOADING:4,GST_REGISTRY:4" gst-launch ...
and maybe send us the relevant section from the log.
