<div dir="ltr"><div>Hi, I am experiencing some issues while using rtp/udp live streaming of TS encapsulated H.264 stream. The sender side pipe line is as gst-launch filesrc location= gst-launch filesrc location=grandma.qcif.yuv blocksize=1 ! videoparse format=0 width=176 height=144 ! x264enc byte-stream=1 ! flutsmux ! rtpmp2tpay ! udpsink host=localhost port=1234. the receiver side the pipeline is as : gst-launch udpsrc port=1234 ! rtpmp2tdepay ! flutsdemux ! ffdec_h264 ! queue ! sdlvideosink The display is jerky and only I frames fets displayed at the sink. The observations we have on the issue so far are the following. 1. The display is fine when we use tcpserversrc at the receiver and tcpclientsink at the sender. 2.The display is fine if we modify the code of udpsrc and make it a non-live src. 3.The display is smooth if we start the transmitter side first and thgen start the receiver. 4.The timestamps of the packets arriving at the sink are the same in both live and non-live cases but in the live case the packets seems to be late when compared with current clock time. 5. The qos messages from the sink make the decoder skip to the next I frame and this continues all the way. 6.The display is fine if we disable the sync property at the sdlvideosink. 7. We tried the pipelin with rtph264pay and depay without TS encapsulation,which works fine. But in this case also at the sink, the sync property gets set to false due to invalid timestamp and the display is fine. 8.Other players like VLC plays it well wih the same sender. Would someone be able to coment on the issue? Regards</div> <div>Ambily </div></div>
