Hello, I'm new in using GStreamer libraries. I want to send an AVI stream (DivX5.0 without audio) using RTP on Windows. I've tried the following command: gst-launch-0.10 filesrc location=C:/Proyecto/Teinemat/GStreamer/Test2/debug/Pelicula.avi !video/x-msvideo !ffdemux_avi !video/mpeg4 !ffdec_mpeg4 !ffenc_mpeg2video ! ffmux_mpegts ! rtpmp2tpay pt=96 ! udpsink host=<a href="http://127.0.0.1">127.0.0.1</a> port=5000 sync=false , but I get this: Setting pipeline to PAUSED ... Pipeline is PREROLLING ... and it stays in this state, but never finishes! i've also tried other commands, like this one: gst-launch-0.10 uridecodebin uri=file://C:/Proyecto/Teinemat/GStreamer/Test2/debug/Pelicula.avi !ffenc_h263p ! video/x-h263 ! rtph263ppay pt=96 ! udpsink host=<a href="http://127.0.0.1">127.0.0.1</a> port=5000 sync=false , but in this case, I get: Setting pipeline to PAUSED ... Pipeline is PREROLLING ... ERROR: from element /pipeline0/uridecodebin0/source: Internal data flow error. Additional debug info: E:\devel-release\src_releases\gstreamer\libs\gst\base\gstbasesrc.c(2165): (function) (): /pipeline0/uridecodebin0/source: streaming task paused, reason not-linked (-1) ERROR: pipeline doesn't want to preroll. Setting pipeline to NULL ... FREEING pipeline ... How can I do that? Thank you
