RE: playbin error

Hi Mark,
      I export GST_PLUGIN_PATH to my gstreamer share library path, and fixed the issue.
Thanks for your help.

Nick

Hi Mark,

Below is my test result:

# gst-inspect
staticelements:  bin: Generic bin
staticelements:  pipeline: Pipeline object

# gst-launch-0.10 playbin2
ERROR: pipeline could not be constructed: no element "playbin2".

It's seems have no element playbin2 in gst-plugins-base, I think something wrong during building package 
gst-plugins-base.
Maybe share library not linked or other .................
Could you give me some advice or tell me what flag should use during building package gst-plugins-base ?

My build environment is arm-base, I’m sure I have install
gst-plugins-base, gst-plugins-good, gst-plugins-ugly, and gst-plugins-bad.

I check /usr/local/lib/gstreamer-0.10 on the target rootfs, the
libgstplaybin.so is found.

Could anyone help me to check if anything wrong ?




It looks like playbin2 is not working on your device.  This can be easily verified without using Rygel.

 From the command line simply type

gst-launch-0.10 playbin2 uri=file:///home/me/myvideo.wmv

where ///home/me/myvideo.wmv is the path to a video file stored locally on your device?  If this doesn't work 
it implies that playbin2 is not working properly on your device.

BTW., are you planning to use Rygel as a DMR or a DMS or both?  If you only want to use the DMS functionality 
you can probably get Rygel to start on your device by disabling the playbin plugin in the rygel.conf file.

In any case, I guess we should see if we can detect the case when playbin is not working and simply disable 
the playbin plugin rather than asserting.

Best Regards,

Mark
