What's the transport being used by raspivid ? As a reference, I took you pipeline and I made it work this way: <PRE> gst-launch-1.0 videotestsrc ! x264enc tune=zero-latency byte-stream=1 ! mpegtsmux ! fdsink fd=1 | \ gst-launch-1.0 -e fdsrc fd=0 ! decodebin ! jpegenc ! multifilesink location=img_%03d.jpeg </PRE> In this example I use MPEG Transport Stream. I also got it to work with avimux, but not with qtmux as it's not streamable format (not without configuration). In the case there is no transport (H264 byte-stream), I could make it work using h264element, or simply setting caps after the fdsrc: <PRE> gst-launch-1.0 videotestsrc ! x264enc tune=zero-latency byte-stream=1 ! fdsink fd=1 | \ gst-launch-1.0 -e fdsrc fd=0 ! h264parse ! decodebin ! jpegenc ! multifilesink location=img_%03d.jpeg cheers, Nicolas </PRE> </BODY> </HTML>
