<div dir="ltr"><div>I don't really understand the workings of it myself, but it looks like you're missing the "sync=false" from the autovideosink in your code. I suspect this is where the choppiness is coming from. </div>As I understand it, "sync=false" means that the videosink displays frames as they arrive rather than waiting for the "correct" time to display them.

TIVidenc1 codecName=h264enc engineName=codecServer ! rtph264pay pt=96 ! udpsink host=192.168.10.4 port=4000 and on the client side we run this command from the terminal: gst-launch-0.10 -v udpsrc port=4000 caps='application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264, sprop-parameter-sets=(string)\"Z0KAHukBQHpCAAAH0AAB1MAIAA\\=\\=\\,aM48gAA\\=\"' ! rtph264depay ! ffdec_h264 ! xvimagesink sync=false And the video streaming works just fine with almost zero lag. To build the android client end, I went through the gstreamer for android tutorials, and in order to test it I simply replaced data->pipeline = gst_parse_launch("videotestsrc ! warptv ! ffmpegcolorspace ! autovideosink", &error); with: data->pipeline = gst_parse_launch("udpsrc port=4000 caps=\"application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264, sprop-parameter-sets=(string)\\\"Z0KAHukBQHpCAAAH0AAB1MAIAA\\\\=\\\\=\\\\,aM48gAA\\\\=\\\"\" ! rtph264depay ! decodebin2 ! autovideosink", &error); with the addition of also adding extra plugins in the Android.mk file, in the tutorial 3 android sample project When I test this code, I can see the video stream coming in, and I don't think the video is necessarily delayed but it the image is only refreshed about once every 2 seconds making the video very choppy and useless for the purpose of this project. Not really sure where to look into as I'm completely new to Gstreamer, but hopefully someone can point me in the right direction. Thanks!
