Hi, I am trying to record synchronised audio and video on iMX51 board from network ( udpsrc ). Video Streaming (iMX51 to iMX51) Sending from iMX51 (via network) mfw_v4lsrc capture-width=320 capture-height=240 fps-d=1 ! mfw_vpuencoder qp=26 framerate=29 codec-type=std_avc width=320 height=240 loopback=false ! rtph264pay max-ptime=60000000 min-ptime=60000000 ! udpsink host=%1 port=%2 sockfd=%3 Receiving on iMX51 (via network) gst-launch -v udpsrc multicast-group=ff18::19:42ee port=17990 caps="application/x-rtp, media=video, clock-rate=90000, payload=96, encoding-name=H264" ! rtph264depay ! ffdec_h264 ! ffmpegcolorspace ! mfw_v4lsink sync=false above works fine Record avi video on iMX51 (via network) gst-launch -v udpsrc multicast-group=ff18::19:42ee port=17990 caps="application/x-rtp, media=video, clock-rate=90000, payload=96, encoding-name=H264" ! rtph264depay ! video/x-h264, height=480, width=640, framerate=30/1 ! avimux ! filesink location=/paxton_apps/video30.avi sync=false Playback avi video on iMX51 gst-launch -v filesrc location=/paxton_apps/video30.avi ! h264parse ! mfw_vpudecoder codec-type=std_avc ! mfw_v4lsink Playback is fast forward ( playback 3 times faster ) Also I have tried to record and playback in 264 format but still fast forward (playback 3 times faster) Record 264 video on iMX51 (via network) gst-launch -v udpsrc multicast-group=ff18::19:42ee port=17990 caps="application/x-rtp,media=(string)video,clock-rate=(int)90000,encoding-name=(string)H264,payload=(int)96" ! gstrtpjitterbuffer drop-on-latency=true latency=50 ! rtph264depay ! h264parse ! "video/x-h264,width=(int)640,height=(int)480" ! filesink location=movie.264 sync=false Playback 264 video on iMX51 gst-launch -v filesrc location=/paxton_apps/movie.264 ! h264parse ! ffdec_h264 ! ffmpegcolorspace ! mfw_v4lsink I have already tried by changing videorate but still does not play normal. Please help me, if anyone has tested pipelind for iMX51 target? Any pipeline which is used to fast forward and slow motion video will also help.
