The pipeline is in playing state. You have to set the added parts(audio bin) to playing state as well. Otherwise, it will not work. But I can not add volume element to audio bin anymore. That is weird.

Thanks. I thought I tried that. So - in the pad added callback - you actually change the pipeline and then set the state to playing? Assume you had already set the state to playing elsewhere in order for the pad added callback to even happen?

sorry I can not share the pipeline with you since it is company property. I have solved the issue. Firstly, make video parts only and run it.connect video source with "pad-added" signal and check if audio is available in the streaming from pad info. If yes, add audio parts(audiobin)to the pipeline and set its state to Playing.

I have exactly the same issue. The symptom I get is just a green screen (like only 1 frame of video has been decoded). I am still hoping someone on here can help with this.
Can you share with me the pipeline you are using please?

If I use playbin, it works fine. How does playbin automatically handle streaming with and without audio?

I have a pipeline for video and audio. If rtsp streaming has both audio and video, it works fine. But if the rtsp streaming does not have audio, the pipeline will freezes.How to add audio part dynamically to the pipeline for rtsp streaming with audio?
