Perhaps there is a third party application that can receive the gstreamer UDP video stream and emulate a hardware webcam that MP could see. Sure, simple setups as above can be created with gst-launch. When you decode it, your local decoder might only use the relative time information from your timestamps, or discard them completely and recalculate timing from the bitrate, which works fine in most, nearly all streams (VLC didn't obey timestamps for. After several hours digging my head, I finally found the answer. 1 from source, as the version 1. 20 port=1234. 4 in the Raspian repository is to old (had problems with G.
