<div dir="ltr">Non-existing PPS generally happens when you try to decode a video stream before receiving the first SPS/PPS. It can also happen if you have a corrupted video stream, such as MP2T encapsulated in RTP with raw RTP signaled. Increase the debugging level and post more of your trace and the entire pipelines. </div><div class="gmail_extra"> <div class="gmail_quote">On Sat, Apr 19, 2014 at 6:37 PM, kayoss12 <<a href="mailto:noureddinetariba@gmail.com" target="_blank">noureddinetariba@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">hello i use this pepeline but it not working in my Raspberry PI and the PC (windows8) i got this warning Warnig client : Additional debug info: gstrtpbasedepayload.c(381): gst_rtp_base_depayload_chain (): /GstPipeline:pipeli ne0/GstRtpMP2TDepay:rtpmp2tdepay0: Received invalid RTP payload, dropping WARNING: from element /GstPipeline:pipeline0/GstRtpMP2TDepay:rtpmp2tdepay0: Coul d not decode stream. also i have warning in RPI WARNING: from element /GstPipeline:pipeline0/GstAlsaSrc:alsasrc0: Can't record audio fast enough Additional debug info: gstaudiobasesrc.c(848): gst_audio_base_src_create (): /GstPipeline:pipeline0/GstAlsaSrc:alsasrc0: Dropped 8820 samples.
