Black screen with ximagesrc

[grijalvaromero]

i try to stream my screen to a rtmp server, but only appears a black screen:
this is my script:

gst-launch-1.0 -v ximagesrc  endx=1919 endy=1079 use-damage=false
show-pointer=true !  video/x-raw,framerate=15/1 ! \
videoconvert ! queue ! x264enc bitrate=1228  ! mux. \
flvmux name=mux ! \
rtmpsink location="rtmp://127.0.0.1:1935/live1/live live=1"

this is the console:

/GstPipeline:pipeline0/GstX264Enc:x264enc0.GstPad:sink: caps = video/x-raw,

 i think it's because no specific width or height but when I put it appears:
"video/x-raw,width=640,height=480,framerate=15/1" !

WARNING: erroneous pipeline: could not link ximagesrc0 to videoconvert0

also i try this:

gst-launch-1.0 -v ximagesrc  endx=1919 endy=1079 use-damage=false
show-pointer=true !  video/x-raw,framerate=15/1 ! \
#videoscale  method=1 !  \
#video/x-raw,width=1400,height=1050,framerate=15/1 ! \
videoconvert ! queue ! x264enc bitrate=1228  ! mux. \
flvmux name=mux ! \
rtmpsink location="rtmp://127.0.0.1:1935/live1/live live=1"

gst-launch-1.0 -v ximagesrc  endx=1919 endy=1079 use-damage=false
show-pointer=true !  video/x-raw,framerate=15/1 ! \
queue ! videorate ! video/x-raw,framerate=15/1 ! videoscale method=1 ! \
video/x-raw-yuv,width=1400,height=1050,framerate=15/1 ! \
videoconvert ! queue ! x264enc bitrate=1228  ! mux. \
flvmux name=mux ! \
rtmpsink location="rtmp://127.0.0.1:1935/live1/live live=1"

suggestions or am I doing wrong?
