h264 and aac stream recording
Locked
 
|
Hi all,
I am trying to make a pipeline to support receiving aac stream and h264 stream and then reconstruct them as a mp4 file The send pipeline I used which i found it no problem on generating rtp stream: gst-launch -m -v filesrc location=/home/video/1.mp4 ! qtdemux name=demuxer \ demuxer.!queue! rtpmp4gpay name=audiopay pt=98 ! udpsink host=172.20.122.9 port=23456 \ demuxer.!queue! rtph264pay name=videopay pt=97 ! udpsink host=172.20.122.9 port=23458 The problem is from the receive pipeline gst-launch -m -v ffmux_mp4 name=mux ! filesink name=filesink location=/home/video/receive.mp4 \ { udpsrc name=audioudp port=23456 num-buffers=100 caps="application/x-rtp, media=(string)audio, clock-rate=(int)22050, encoding-name=(string)MPEG4-GENERIC, encoding-params=(string)2, streamtype=(string)5, profile-level-id=(string)2, mode=(string)AAC-hbr, config=(string)1390, sizelength=(string)13, indexlength=(string)3, indexdeltalength=(string)3, payload=(int)98" ! gstrtpjitterbuffer name=audiojitter ! rtpmp4gdepay queue-delay=0 name=audiodepay ! queue name=audioqueue } ! mux.audio_0 \ { udpsrc name=videoudp port=23458 num-buffers=100 caps="application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264, profile-level-id=(string)42c00d, sprop-parameter-sets=(string)\"Z0LADZp0Cg/YCIAAAAMAgAAAD0eKFVA\\=\\,aM48gA\\=\\=\", payload=(int)34" ! gstrtpjitterbuffer name=videojitter ! rtph264depay queue-delay=0 name=videodepay ! queue name=videoqueue } ! mux.video_0; When I have the sprop-parameter-sets in the h264 rtp caps, it fails to connect gstrtpjitterbuffer and rtph264depay together I wonder if it is related to those \" or \\ in the caps line Then I remove the sprop-parameter-sets in the caps, they connect together but I got error when i start to send media stream to the ports Here is the error Got Message from element "mux" (error): GstMessageError, gerror=(GstGError)(NULL), debug=(string)"gstffmpegmux.c\(476\):\ gst_ffmpegmux_collected\ \(\):\ /pipeline0/mux:\012Failed\ to\ write\ file\ header\ -\ check\ codec\ settings"; ERROR: from element /pipeline0/mux: Could not configure supporting library.

Hi all,
After I make some change in my pipeline, all the element connect together However, it still dont work as expected When I start the send pipeline, error come out from the receive pipeline Got Message from element "mux" (error): GstMessageError, gerror=(GstGError)(NULL), debug=(string)"gstffmpegmux.c\(476\):\ gst_ffmpegmux_collected\ \(\):\ /pipeline0/mux:\012Failed\ to\ write\ file\ header\ -\ check\ codec\ settings"; ERROR: from element /pipeline0/mux: Could not configure supporting library. Additional debug info: gstffmpegmux.c(476): gst_ffmpegmux_collected (): /pipeline0/mux: Failed to write file header - check codec settings What's the problem of that? I have already put those caps for them. Here is the pipeline I am using now send pipeline: gst-launch -m -v filesrc location=/home/video/1.mp4 ! qtdemux name=demuxer \ demuxer.!queue! rtpmp4gpay name=audiopay pt=98 ! udpsink host=172.20.122.9 port=23456 \ demuxer.!queue! rtph264pay name=videopay pt=97 ! udpsink host=172.20.122.9 port=23458 receive pipeline: gst-launch -m -v ffmux_mp4 name=mux ! filesink name=filesink location=/home/video/receive.mp4 \ { udpsrc name=audioudp port=23456 num-buffers=1000 caps="application/x-rtp, media=(string)audio, clock-rate=(int)22050, encoding-name=(string)MPEG4-GENERIC, encoding-params=(string)2, streamtype=(string)5, profile-level-id=(string)2, mode=(string)AAC-hbr, config=(string)1390, sizelength=(string)13, indexlength=(string)3, indexdeltalength=(string)3" ! gstrtpjitterbuffer name=audiojitter ! rtpmp4gdepay queue-delay=0 name=audiodepay ! queue name=audioqueue } ! mux.audio_0 \ { udpsrc name=videoudp port=23458 num-buffers=1000 caps="application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264, profile-level-id=(string)42c00d, sprop-parameter-sets=(string)\"Z0LADZp0Cg/YCIAAAAMAgAAAD0eKFVA\\=\\,aM48gA\\=\\=\"" ! gstrtpjitterbuffer name=videojitter ! rtph264depay queue-delay=0 name=videodepay ! queue name=videoqueue } ! mux.video_0; anyone could help?
