Thanks to the help from Aurelien, I successfully setup the pipeline and it's rolling good. Now I find that with the packet drop is quite frequent even in locale area network. I have been tried to configure the parameter "latency" on rtspsrc/gstrtpjitterbuffer, but they didn't help. The video source rate is 788kbps, lasts 6 seconds. By dumping the received file to disk, it turned out that only a quarter of the stream was successfully received ("gst-launch -v rtspsrc location=rtsp://<a rel="nofollow" target="_blank" href="http://10.38.164.205/water_mpeg4.mp4">10.38.164.205/water_mpeg4.mp4</a> ! gstrtpjitterbuffer latency=20000 ! rtpmp4vdepay ! filesink location=./stream.m4v"). Most of them was dropped for some reason I don't know. How can I get information regarding those drooped packets? Thank you for your advice :)<br><br>Best regards<br><br>-felix<br></div></div></div></div><br> <hr size="1"> Envoyé avec <a href="http://us.rd.yahoo.com/mailuk/taglines/isp/control/*http://us.rd.yahoo.com/evt=52423/*http://fr.docs.yahoo.com/mail/overview/index.html">Yahoo!
