<div dir="ltr"><div><div><div><div>I am working with the GStreamer RTSP server simply trying to relay an RTP stream. Here is my desired pipeline:<br><br> udpsrc port=%d name=RTPSrc ! application/x-rtp,media=video,payload=96,clock-rate=90000,encoding-name=H264"<br>
" ! rtph264depay byte-stream=true name=RTPDePay ! video/x-h264 ! h264parse ! rtph264pay name=pay0 pt=96 )<br><br></div>This pipeline doesn't work in this context. This string is actually used to generate the real pipeline which has the udpsrc port set. I have tested this pipeline in a script where I added a udpsink to send the RTP to another system to render. That worked fine.<br>
<br></div>This pipeline takes about 5 seconds to reach the prerolled state, though it is a live pipeline. At that point it seems that VLC disconnects the TCP connection (I don't know why but wireshark showed a TCP FIN). The video source should be feeding an IFrame about once per second. The SPS/PPS headers are re-transmitted every 3-5 seconds.<br>
<br></div><div>I did get a message that I don't understand.<br><br>(<unknown>:10559): WARNING **: ignoring stream 0 without media type<br></div><div><br></div>I substituted a test pipeline based on videotestsrc feeding the x264enc to rtph264pay and that (sort of) worked. By 'sort of' I did get a couple of frames displayed on VLC but there weren't many. It seemed like the stream wasn't working well, which is confusing but a secondary issue at the moment.<br>
<br></div>Would anyone please care to comment on this issue? I am running out of ideas.<br><br>Thank you,<br>Chuck Crisler<br></div>
