<div dir="ltr">You are not transmitting RTP on the network, you are transmitting MP2T. You need rtpmp2tpay between the mpegtsmux and the udpsink on the RPi. I don't think that the receiver needs to specify the payload type. I don't think that the RPi needs the h264parse. I assume that the rpicamsrc is generating complete H264 frames. </div><div class="gmail_extra"> <div class="gmail_quote">On Tue, Mar 11, 2014 at 3:46 AM, cxphong <<a href="mailto:caoxuanphong.khtn@gmail.com" target="_blank">caoxuanphong.khtn@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hello, I have ffdec_h264 error when streamed video + audio from rpi to Linux PC using the following commands: Rpi (Sender): *gst-launch-1.0 rpicamsrc bitrate=1000000 !
