Re: Rygel created UPnP stream help please

[Andrej Falout <andrej falout org>]

Thanks Jens, getting close :-)

This works, using XBMC as renderer:

python /opt/push2play/rendererconsole.py --rendererPath=/com/intel/RendererServiceUPnP/server/1 --playURI=http://192.168.1.113:1122/GstLaunch/i/dGVzdA==.mp3

And I hear a 1khz tone.

But trying the same command on Onkyo receiver produces:

Traceback (most recent call last):
  File "/opt/push2play/rendererconsole.py", line 349, in <module>
    renderer.play()
  File "/opt/push2play/rendererconsole.py", line 102, in play

    message, timeout)
dbus.exceptions.DBusException: com.intel.RendererServiceUPnP.OperationFailed: Operation failed: Resource not found

And Rygel say:

(rygel:15141): Rygel-WARNING **: rygel-http-request.vala:91: Invalid seek request

Removing ".mp3" part makes no difference.

Your help is very much appreciated!

For the reference :

rygel --version
Rygel 0.12.7

(I tried to compile current version of Rygel but failed miserably with my head spinning in version dependency nightmare (on Fedora 16). Hopefully this is not one of the issues that was fixed since this version....)

Well we can't really guarantee the compliance. We assume it's matching
for files the have identified as such or our transcoded streams (apart
from WMV).

No, you can't really guess it if you don't know how URIs are generated.

And with this line, you'll never be able to find it. You need to add
"enable=true" to the [GstLaunch] section.

In general it's
http://ip:port/PluginName/i/SomeBase64EncodedStuff.extension

ip is the interface Rygel is bound to, port can either be configured in
rygel.conf or set via -p commandline parameter. "/i/" denotes an item
and the base64 stuff is plug-in specific and the extension optional

For GstLaunch it is the part before -launch, so in your case my.

Let's say you've started rygel with -p 12345 -n lo, you'd have something
like:

http://127.0.0.1:12345/GstLaunch/i/bXk= or
http://127.0.0.1:12345/GstLaunch/i/bXk=.mp3

Most of the time it's not possible to specify the filename.
