cannot link my rtpasfpay to gstrtpbin

[Irfan Shaikh-2]

Hi sudarshan,

                   I have created a rtpasfpay plug-in. I have used the
fillowing pipeline which works fine.

   gst-launch videotestsrc ! ffmpegcolorspace ! ffenc_mpeg4 ! ffmux_asf !
asfparse ! asfpay ! udpsink port=5000 host=10.60.3.55

                   Mpeg4 video gets streamed in above case .....


      But when i use gstrtpbin, asfpay does not link with gstrtpbin

  gst-launch videotestsrc ! ffmpegcolorspace ! ffenc_mpeg4 ! ffmux_asf !
asfparse ! asfpay ! gstrtpbin localport=5000 destinations=10.60.3.55:5000

      I have set the src pad capabilities of asfpay to ANY. As well as i
tried with "application/x-rtp" still it shows cannot link..


Regards,
Irfan

Hi, gstreamer-devel:

    You should specify which pad you wanna use in gstrtpbin because gstrtpbin can send/receive rtp/rtcp. In you example, you should request a `send_rtp_sink_%d' pad if you wanna send stuffs in RTP packet format. Here is an example pipeline from gstrtpbin's manual, it sends not only RTP packets but also RTCP:

gst-launch gstrtpbin name=rtpbin \
        v4l2src ! ffmpegcolorspace ! ffenc_h263 ! rtph263ppay ! rtpbin.send_rtp_sink_0 \
                  rtpbin.send_rtp_src_0 ! udpsink port=5000                            \
                  rtpbin.send_rtcp_src_0 ! udpsink port=5001 sync=false async=false    \
                  udpsrc port=5005 ! rtpbin.recv_rtcp_sink_0                           \
        audiotestsrc ! amrnbenc ! rtpamrpay ! rtpbin.send_rtp_sink_1                   \
                  rtpbin.send_rtp_src_1 ! udpsink port=5002                            \
                  rtpbin.send_rtcp_src_1 ! udpsink port=5003 sync=false async=false    \
                  udpsrc port=5007 ! rtpbin.recv_rtcp_sink_1

    Refer to gstrtpbin's manual for more details.
