<div>HI,<br clear="all"></div><div><br></div><div>I'm trying to build the following pipeline with a C application :</div><div>gst-launch -e udpsrc port=5000 caps="application/x-rtp, media=video, encoding-name=MP2T-ES" ! rtpmp2tdepay ! mpegtsdemux ! filesink location=videodstRDO.mpeg</div>
<div><br></div><div>when using gst-launch it works fine, but when I use a C application here is the error I get (with GST_DEBUG=3) :</div><div>0:00:00.032693078 12164 0x1912010 INFO GST_ELEMENT_PADS gstutils.c:1698:gst_element_link_pads_full: trying to link element tsdemux:(any) to element mpeg2dec:(any)<br>
