<div dir="ltr">You can't decode the h264 stream without an SPS/PPS. If you think that it worked then you probably missed something. Since you can't re-transmit the SPS/PPS with rtpmp2tpay (don't know why not) you should look further upstream (at the source?) and see if you can set the SPS/PPS/IFrame (or GOP) interval. </div><div class="gmail_extra"> <div class="gmail_quote">On Sat, Mar 15, 2014 at 2:49 AM, cxphong <<a href="mailto:caoxuanphong.khtn@gmail.com" target="_blank">caoxuanphong.khtn@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">I found out the reason of my problem. It causes by missing *SPS/PPS* so *ffdec_h264* can't decode the stream. Weird, when receiver run before sender, *ffdec_h264* can decode the stream without *SPS/PPS* from sender. Could someone please explain it? And If I stream only video, I can use *rtph264pay* with option *config-interval* to resend SPS/PPS so ffdec_h264 can decode the stream, but here I stream video+audio so I used *rtpmp2tpay*. So I don't know how to fix this problem with *rtpmp2tpay*.
