[gst-devel] h264 and aac stream recording

[Terry Leung]

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?

Terry
