Problem with H.265 Video to Chrome via Pion (v4.1.1) #3136

I'm trying to stream H.265 video from GStreamer to Chrome (v136) using Pion WebRTC (v4.1.1), based on the gstreamer-send example:
👉 https://github.com/pion/example-webrtc-applications/blob/master/gstreamer-send

My GStreamer pipeline is:

gst-launch-1.0 rtspsrc location=rtsp://192.168.0.115:8554 ! rtph265depay ! decodebin ! videoconvert ! video/x-raw ! appsink name=appsink

I do see packetsReceived and incoming RTP packets in chrome://webrtc-internals, but no frames received.

A few questions:

• Has anyone successfully streamed H.265 to recent versions of Chrome using Pion?
• Is there anything obviously wrong with my GStreamer pipeline or the way I'm feeding frames into the track?
• Could this be an SDP/capability mismatch? Chrome 136 is supposed to support H.265, but I’m unsure if there's a specific format or parameter set needed

Any guidance or working examples would be greatly appreciated!

Thanks!
