Try out the below:
gst-launch-0.10 videotestsrc is-live=true* num-buffers=100* !
'video/x-raw-yuv,format=(fourcc)I420,width=640,height=480,framerate=(fraction)25/1'
! x264enc ! queue ! mux. avimux name=mux ! filesink location=testV3.avi
When you are recording from live pipelines and you stop gst-launch with
ctrl+c, it simply shuts the pipeline down, no EOS is sent. Some muxers need
to send data after they receive EOS to finish the file properly, if no EOS
is received the file ends up in an unconsistent state.
