Ubuntu 24.04

What ever url i try to stream (via parole or radiotray-ng) gstreamer gives me this error:

GLib-CRITICAL **: xx:xx:xx.433: g_uri_get_scheme: assertion ‘uri != NULL’ failed

How to fix?

run first from command line
gst-launch-1.0 playbin3 uri=your_uri
to see if your uri works. Also show your uri here.

Plz see:

Can you try:
gst-launch-1.0 urisourcebin uri=https://icecast.vrtcdn.be/stubru-high.mp3 ! decodebin3 ! audioconvert ! autoaudiosink

rvh007 · April 7, 2025, 8:42am

Pretty much the same result:

I tested the following pipeline on Linux and it works.
gst-launch-1.0 souphttpsrc location=https://icecast.vrtcdn.be/stubru-high.mp3 ! decodebin ! audioconvert ! autoaudiosink

rvh007 · April 8, 2025, 8:33am

Hmm, stil the same. Do i miss any dependencies or other?

My guess would be that you have an invalid proxy configuration.

Can you run with

GST_DEBUG=6 and attach the whole log here
G_DEBUG=fatal_warnings in a debugger and get a backtrace of the first critical warning (after installing all relevant debug symbols)

rvh007 · April 9, 2025, 9:15am

Hi,

thank you for your remarks.

Attached the output, it contains these bash-color escapes, that make it difficult to read…

logfile is 8MB, not sure how to upload to here....

rvh007 · April 11, 2025, 8:22am

Here is the logfile:

That doesn’t work: “The URL doesn’t have the correct format.”
