Hi All,
i am facing a problem trying to mux an audio and video stream into a 3gp file. The pipeline i am using is

gst-launch -v filesrc location=/home/rmittal/noblogs.jpg ! jpegdec ! videoscale ! video/x-raw-yuv , width = 22 , height = 18 ! videobox border-alpha=0 alpha= 0.5 top=-126 left=-0 ! videomixer name=mix background=black ! ffmpegcolorspace ! video/x-raw-yuv,format=\(fourcc\)YUY2 ! videoscale ! video/x-raw-yuv , width = 176 , height = 144 ! ffmpegcolorspace ! ffenc_h263 ! queue ! ffmux_3gp name=3gpmux ! filesink location= mixd.3gp filesrc location=get_video.flv ! decodebin name=dbin ! queue ! ffmpegcolorspace ! videoscale ! video/x-raw-yuv, width=176, height=144 ! mix. dbin. ! audioconvert ! amrnbenc name=amrenc ! queue name=que2 ! 3gpmux.


what i am doin is i want to decode an flv file , process the video stream , and then mux this video stream into a 3gp file along with the original audio stream..
but the above pipeline is not working.

Pls suggest something...
