<div style="font-family:garamond,new york,times,serif;font-size:12pt"><div style="font-family: garamond,new york,times,serif; font-size: 12pt;">Thanks Marco. I think you were very clear on the previous mail too but I dint understand you well. The problem is: The h264 file that I am using is not encoded by one of the gstreamer elements. I encode the yuv file using another encoder which I want to evaluate. Then, I stream the file with gstreamer using the pipe from my post, receive it over udpsrc and want to store it in the x-264 format in a .264 file without any multiplexing (raw h264 stream) so I can decode and process it later. I have an h264 stream from the h264 reference encoder so it must be h264 compatible. I have made sure it does have SEI messages in it. However, it doesnt have SPS/PPS messages since it needs to be compatible with the baseline profile of h264. I thought (from your earlier mail) that setting the property "config-interval" should solve my problem but it hasnt. Obviously! Since I HAVE no SPS/PPS in my stream. Also, I need a raw .264 file at the output to evaluate and decode using another decoder element, not part of gstreamer. That's why I dont care about muxing it into a file format like mp4 and avi. Yet, I tried that. I see that there is no muxer for h264 files (ffmux_ipod also tries to mux the stream as an mpegts stream if I am right). Still, I tried using avimux/mp4mux to mux the stream into avi/mp4 container. I get this error: ERROR: from element /GstPipeline:pipeline0/GstUDPSrc:udpsrc0: Internal data flow error. Additional debug info: gstbasesrc.c(2543): gst_base_src_loop (): /GstPipeline:pipeline0/GstUDPSrc:udpsrc0: streaming task paused, reason not-negotiated (-4) Execution ended after 3772400353 ns. I think this is because the incoming stream from udpsrc does not have mp4 hint information or other SPS/PPS information it is supposed to have. Of that, I cant seem to find a solution. I think the crux of my problem is that I am using an external encoder. That is why 'h264parse' gives me no "codec-data" field in caps as expected from the sender side. Only this: /GstPipeline:pipeline0/GstH264Parse:h264parse0.GstPad:src: caps = video/x-h264, stream-format=(string)byte-stream As a result, I dont  have a suitable value to set in the "codec-data" field in the receiver capsfilter I put between depayloader and filesink. You think I understand it right? There is something that can be done to solve this? <div style="font-family: times new roman,new york,times,serif; font-size: 12pt;"><hr size="1">From: Marco Ballesio [via GStreamer-devel] <<a href="/user/SendEmail.jtp?type=node&node=2252445&i=0" target="_top" rel="nofollow">[hidden email]</a>> To: Farah <<a href="/user/SendEmail.jtp?type=node&node=2252445&i=1" target="_top" rel="nofollow">[hidden email]</a>> Sent: Sat, June 12, 2010 1:00:28 AM Subject: Re: Using gstreamer to transmit H264 file over RTP Hi, as I pointed out in the previous mail (I'm sorry if I've not been clear enough) you need to explicitly set the codec_data parameter in the receiving side caps. I also suggest you to mux the depayloaded h264 (even if you're using annex B it's not a container format, only a codec). The easiest way is to put the muxer between the h264 depayloader and the filesink.
