[Asterisk-video] Converting video files into .h263

[Kevin Cross]

By browsing on the mailing list I learned that its possible to generate .h263 asterisk friendly files with gstreamer.
The script below it's supposed to do just that, however I get error when trying it out locally.

gst-launch filesrc location=AstriDevCon_Europe_2006.mov ! qtdemux name=demux ! ffdec_h263 ! videoscale ! video/x-raw-yuv,width=352,height=288 ! ffenc_h263 rtp-payload-size=512 ! rtph263pay ! asteriskh263 ! filesink location=avout.h263 demux. ! queue ! ffdec_adpcm_ima_qt ! audioconvert ! audioresample ! audio/x-raw-int,rate=8000,channels=1 ! wavenc ! filesink location=avout.wav 

I was wondering if this script is expecting some specific type of file or if I am doing something else wrong. Any pointers in how to generate .h263 video files for asterisk would be helpful.
