 hi all, i want to create an application which can simultaneouslycapture live audio-video data(from microphone and webcam) , encode it and stream it using rtp ,  at the client side i want to receive av data and play it( what about av sync) 

using gstreamer-0.10.12, gst-plugins-base-0.10.12 ,gst-ffmpeg-0.10.2

i tried the following

 

 

[root at pritesh mp4creator]# gst-launch -v v4lsrc ! videoscale !

"video/x-raw-yuv,frame-rate=(double)15.0" ! queue ! ffmpegcolorspace !

ffenc_mpeg4 ! ffmux_mp4 ! filesink location=webcam.mp4

Setting pipeline to PAUSED ...

/pipeline0/v4lsrc0.src: caps = video/x-raw-yuv, format=(fourcc)I420,

width=(int)160, height=(int)120, framerate=(fraction)25/1,

frame-rate=(double)15

Pipeline is live and does not need PREROLL ...

Setting pipeline to PLAYING ...

/pipeline0/videoscale0.sink: caps = video/x-raw-yuv, format=(fourcc)I420,

frame-rate=(double)15

/pipeline0/ffmpegcsp0.sink: caps = video/x-raw-yuv, format=(fourcc)I420,

width=(int)160, height=(int)120, framerate=(fraction)25/1,

frame-rate=(double)15

/pipeline0/ffenc_mpeg40.src: caps = video/mpeg, width=(int)160,

height=(int)120, framerate=(fraction)25/1, mpegversion=(int)4,

systemstream=(boolean)false

/pipeline0/ffenc_mpeg40.sink: caps = video/x-raw-yuv, format=(fourcc)I420,

frame-rate=(double)15

/pipeline0/ffmux_mp40.video_0: caps = video/mpeg, width=(int)160,

height=(int)120, framerate=(fraction)25/1, mpegversion=(int)4,

systemstream=(boolean)false

after some time stopped the procedure

 

Caught interrupt -- handling interrupt.

Setting pipeline to NULL ...

FREEING pipeline .

in the created mp4 file only mdat exists and i cannot play it with any

player

any ideas
