[gst-devel] Caps negotiation problem with gstrtpbin

[Irfan Shaikh]

Hi All,

      I have element "rtpasfpay" i.e asfpay in following pipeline. I want to link it with "gstrtpbin" 

[root at blr0227 rtp]# gst-launch-0.10 -vvv gstrtpbin name=rtpbin filesrc blocksize=1048576 location=/root/mpeg4new.dat ! vbuffer video-codec=1 ! mpeg4videoparse ! ffmux_asf ! asfparse ! asfpay ! rtpbin.send_rtp_sink_2 rtpbin.send_rtp_src_2 ! udpsink port=5000 host=10.60.3.104 name=vrtpsink rtpbin.send_rtcp_src_2 ! udpsink port=5001 host=10.60.3.104 sync=false async=false name=vrtcpsink udpsrc port=5005 name=vrtpsrc ! rtpbin.recv_rtcp_sink_2
vbuffer->Video_codec = 1 

** (gst-launch-0.10:21780): CRITICAL **: gst_ffmpeg_mux_simple_caps_set_int_list: assertion `GST_CAPS_IS_SIMPLE (caps)' failed
_init function ended 
WARNING: erroneous pipeline: could not link asfpay0 to rtpbin

llly i cannot use gstrtpbin even with "videotestsrc ! ffenc_mpeg4 !" instead of "filesrc blocksize=1048576 location=/root/mpeg4new.dat ! vbuffer video-codec=1 ! mpeg4videoparse !"
  

I have set the caps in asfpay as follows {I have also tried with caps "ANY"}:

#define SRC_CAPS \
  "application/x-rtp, "                                          \
  "media = (string) { \"application\", \"video\", \"audio\" }, " \
  "clock-rate = (int) [1, MAX ], "                               \
  "encoding-name = (string) \"x-asf-pf\""

static GstStaticPadTemplate src_factory = GST_STATIC_PAD_TEMPLATE ("src",
    GST_PAD_SRC,
    GST_PAD_ALWAYS,
    GST_STATIC_CAPS ("SRC_CAPS")
    );


    My friend has created a element "rtpmjpegpay" with similar caps and similar template only difference was in _chain(). But his element links with above pipeline.

Regards,
Irfan
