Playbin3 can’t accept caps from testbinsrc in 1.22.2

Describe your issue

Attempting to use any of the example launch lines from the testsrcbin documentation that uses playbin3 and that also defines caps, fails to play with multiple errors.

Using gst-play-1.0 to play the same testsrcbin URI that includes caps plays without error.

Expected Behavior

Playbin3 should be able to accept caps defined in the testbinsrc URI without leading to an internal data stream error.

Observed Behavior

Pipeline fails to play.

Setup

  • Fedora 38
  • gstreamner 1.22.2
  • gst-launch-1.0 playbin3 uri="testbin://video,pattern=green,caps=[video/x-raw,width=1920,height=1080,framerate=30/1]"

Steps to reproduce the bug

  1. Any pipeline from gst-launch-1.0 that uses playbin3 and the testbin:// uri that includes caps.

How reproducible is the bug?

Always

Screenshots if relevant

Solutions you have tried

No errors using gst-play-1.0.

Same errors when using playbin3 and testsrcbin from Rust.
