Without seeing the other pipelines you have tried, I came up with this: gst-launch-1. live streaming was displayed successfully with below pipeline: appsrc ! videoconvert ! autovideosink. Unfortunately not on the 64-bits systems, due to the missing Userland video engine. Indeed output video frames will have the geometry of the biggest incoming video stream and the framerate of the fastest incoming one. 0*. 0 filesrc location=movie. vj fs zf zp uc hp mw nn lv nc
