Please try not using decodebin. Based on the profile that was set (via the profile property), EncodeBin will internally select and configure the required elements (encoders, muxers, but also audio and video converters) so that you can provide it raw or pre-encoded streams of data in Package – GStreamer Base Plug-ins. You can see encodebin. The tee element is useful to branch a data flow so that it can be fed to multiple elements. Instead, you should use the appsink element, which is made specifically to allow applications to receive video frames from the Your problem arises from the fact that decodebin is not actually a real element. playsink – Convenience sink for multiple streams . single video frames from the stream and their associated timestamps.
