How can I set properties of plugins, loaded by playbin2, launched with gst-launch?

[wl2776]

I am adding some functionality to the RTSPsrc plugin.
I use
$ gst-launch --gst-plugin-path=`pwd` --gst-debug=rtspsrc:5 playbin2 uri=rtsp://192.168.24.21/1286_bbc_world_news_2009_06_04_22_00_000.mpg

This loads my custom rtspsrc plugin, situated in the current directory.
I'd like to set its 'debug' property to true.
How can I do this?

gst-launch --gst-plugin-path=`pwd` --gst-debug=rtspsrc:5 playbin2
uri=rtsp://192.168.24.21/1286_bbc_world_news_2009_06_04_22_00_000.mpg rtspsrc
0::debug=true

if your instance of rtspsrc is called "rtspsrc0".

gst-launch --gst-plugin-path=`pwd` --gst-debug=rtspsrc:5 playbin2
uri=rtsp://192.168.24.21/1286_bbc_world_news_2009_06_04_22_00_000.mpg rtspsrc
0::debug=true

if your instance of rtspsrc is called "rtspsrc0".

Unfortunately, this doesn't work.
playbin2 creates the element "source", but playbin2 creates the rtspsrc much after gst-launch parses the command line.

thant should not be a problem. gst-launch keeps pending set() actions until the
eleemnt with the name has been created.

That is.
My command line is

gst-launch --gst-debug=rtspsrc:5,GST_REGISTRY:0,*:4 --gst-debug-no-color --gst-plugin-path=`pwd`/.libs playbin2 uri=$location "source::debug"=true 2> playbin2.out 1>&2

And the file playbin2.out contains only two words ASSIGNMENT: one for uri and another for source::debug, and that assignment is unsuccessful.

Ok, will write a simple launcher in C.

How come you belive that the instance is called "source", in contrary to
"rtspsrc0" as I suggested? Please run gst-launch -v playbin2 ... first and
figure out the instance name.

1. I've seen it in the debug messages. gst-launch or someone else told me that it has "created rtspsrc instance named "source"".
2. I wrote a simple launcher in C and added the call to GST_DEBUG_BIN_TO_DOT_FILE
player.png I've uploaded it to the Nabble, hope, the link will be attached to my message.
3. Here is the output of gst-launch -v:

I am sorry, it needs the whole path but as:

Again, this doesn't work.

I also tried playbin20::uridecodebin0::debug=true with the same result.
From what I can see, the uridecodebin0 doesn't exist, when the command line is parsed, and this assignment is failed at that time, and is never being retried.

Indeed, you are right! I made a first attempt to fix it at,
https://bugzilla.gnome.org/show_bug.cgi?id=613215

but just realize that it is not enough. I'll keep working on it.

And now with working patch. The whole implementation of the feature was
buggy :) I hope you can try and confirm.

Thank you.
I am using the versions from the ubuntu repositories in Linux and the OSSBuild (http://www.gstreamer-winbuild.ylatuya.es/doku.php?id=start) in Windows.

I will try the patch as soon as it will be available in either location.
Currently I am having troubles with OSSBuild. For some reason it crashes on my system.

GStreamer 0.10.29
