Hi, <div class="gmail_quote">On Fri, Sep 17, 2010 at 10:58 PM, Gary Thomas <<a href="mailto:gary@mlbassoc.com">gary@mlbassoc.com</a>> wrote: <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> I'm trying to run gstrtpbin over a network, in particular, the examples server-v4l2-H264-alsasrc-PCMA.sh client-H264-PCMA.sh I'm using gst-plugins-good-0.10.20 (latest version I think) I get widely varying results. * video (or audio) data freezes. * the pipeline spontaneously breaks (ERROR: from element /GstPipeline:pipeline0/GstAutoAudioSink:autoaudiosink0/GstPulseSink:autoaudiosink0-actual-sink-pulse: pa_stream_writable_size() failed: Connection terminated) * no video (or audio) at all What's the best way to debug this? </blockquote><div> running your pipeline after setting GST_DEBUG to a proper value (I suggest you to begin with 2) will give you some hints about what's going wrong. Increasing the number increases the verbosity. </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">In particular the last case where I never get any video data displayed, I can see lots of it being shipped to my client (rtp + rtcp packets all look good). How can I discover why there is no video? </blockquote><div> If you're dealing with the network, checking for lost packets is another good starting point. Even if you've more than 80% of the video packets being properly received, you may not see anything because of no key frames ever being completely received.
