      @SGaist thank you, I tryed to use tee, but that is more complicated to do, i actually don't want to Watch and Save/record.
      I would like to only save the video without displaying it.

      after some houres i got this broken pipeline..

      I have lot of troubles on how to set up the format for the video and write it to a file
      I use ultraVnc server

      "rfbsrc host=xx.xx.xx.xx port=5900 password=pw view-only=true   TODO : set up video format    ! mpegtsmux ! filesink location=testvideo.mp4"
      

      i have this output

      ** (QVNCClient.exe:10252): CRITICAL **: gst_video_info_set_format: assertion 'format != GST_VIDEO_FORMAT_UNKNOWN' failed

        You have here an example of pipeline with h264 recording.

          @SGaist hi,
          I am still struggling with Gstreamer.

          Could you please try to see where the probleme is ?
          i try this pipeline :

          gst-launch-1.0 -v rfbsrc host=xx.xx.x.xx port=5900 password=passw view-only=true !
          tee name = t ! queue ! omxh264enc ! 
          'video/x-h264, stream-format=(string)byte-stream' ! h264parse ! qtmux ! 
          filesink location=test.mp4 t. ! queue ! videoscale ! video/x-raw, 
          width=480,height=270 ! xvimagesink -e sync=false
          

          OUTPUT :
          *(gst-launch-1.0:8672): GStreamer-CRITICAL *: gst_element_make_from_uri: assertion 'gst_uri_is_valid (uri)' failed
          WARNING: erroneous pipeline: no element "omxh264enc"

          I downloaded and installed x264 from here but i still get same error

          Maybe there is a simple way to just connect to VNC srv and only record without displaying.
          Or a simple tool that i can start with QProcess

            i tryed like this also :

            gst-launch-1.0 rfbsrc host=xx.x.x.xx port=xxxx password=xxxx view-only=true ! videoconvert ! x264enc ! flvmux ! filesink location=xyz.flv
            

            OUTPUT : WARNING : erroneous pipeline : no element "x264enc"

            I found "x264enc" is part of gst-plugins-ugly but cant fugure out how to install tath missing plugin. I downloaded it from here

            I also found a tool : vnc2flv
            i need to build it with python but when i try i get :

            error print version
            Missing parentheses in call to 'print'. Did you mean print(version)

                  Because the code is written for Python 2 and you are using Python 3

                  What set of plugins did you get when installing on Windows ?

                      Then use the openh264enc encoder in place of the other.

                        @SGaist thanks for the suggestion,

                        I tryed to adapt this exemple with openh264enc :

                        gst-launch-1.0 -v rfbsrc host=10.81.4.97 port=5900 password=pa009v view-only=true ! queue ! openh264enc ! "video/x-h264, stream-format=(string)byte-stream" ! h264parse ! qtmux ! filesink location=test.mp4 
                        

                        output:

                        WARNING: erroneous pipeline: could not link queue0 to openh264enc0
                        

                        if i remove the 'queue' element then i got

                        WARNING: erroneous pipeline: could not link rfbsrc0 to openh264enc0
                        

                        How to link my rfbsrc to openh264enc please ?

                          I tryed to add 'decodebin' between my rfbsrc and the openh264enc ,

                          Now i have format issue again.. a .mp4 file is created but empty, can this be related to my VNC Server ? i use Ultra VNC as server

                          gst-launch-1.0 -v rfbsrc host=xx.xx.x.xx port=5900 password=xxxx view-only=true ! decodebin ! "video/x-h264, stream-format=(string)byte-stream" ! openh264enc ! h264parse ! qtmux ! filesink location=test.mp4

                            Hi,
                            @SGaist I finally made this working pipeline :

                            gst-launch-1.0 -v rfbsrc host=xx.xx.x.xx port=5900 password=passw view-only=true ! videoconvert !  openh264enc !  "video/x-h264, stream-format=(string)byte-stream" ! openh264dec !  autovideosink
                            

                            The remote gui is displayed in an internal GStreamer window .

                            Now i only replace the autovideosink by filesink location=vid.mp4 to save the video to a file instead of displaying it.

                            gst-launch-1.0 -v rfbsrc host=xx.xx.x.xx port=5900 password=passw view-only=true ! videoconvert !  openh264enc !  "video/x-h264, stream-format=(string)byte-stream" ! openh264dec !  filesink location=vid.mp4
                            

                            The video file is created (and not empty) but i can't play it with WindowsMediaPlayer or VLC
                            I tryed filesink location=vid.h264 and enabled H264 Demuxer for VLC but still can't open the file.

                            edit :
                            In some exemples i can see that the last step before filesink is XXXXmux , but if i try

                            gst-launch-1.0 -v rfbsrc host=10.81.4.68 port=5900 password=pa009v view-only=true ! videoconvert !  openh264enc  ! flvmux  !  filesink location=test.flv
                            

                            i get : WARNING: erroneous pipeline: could not link openh264enc0 to flvmux0

                            Thank you for any suggestion

                              I added missing h264parse and mp4mux before writing to the file

                              Now the pipeline looks like this :

                              gst-launch-1.0 -v rfbsrc host=xx.xx.x.xx port=5900 password=passw view-only=true 
                              !  videoconvert ! openh264enc bitrate=4096 
                              ! "video/x-h264, stream-format=(string)byte-stream" 
                              ! h264parse 
                              ! mp4mux 
                              ! filesink location=video.mp4  sync=false
                              

                              but the video file is still not 'playable'
                              i read on github
                              "Some muxers such as mp4mux write additional information to disk when they receive EOS. Without that extra information, the file is useless."

                              so i try to pass -e instead of -v , the file is created and grows in size (still not playable), but when i press ctrl+c to stop i get this error :

                              handling interrupt.Interrupt: Stopping pipeline ...EOS on shutdown enabled -- Forcing EOS on the pipeline
                              Waiting for EOS...ERROR: from element /GstPipeline:pipeline0/GstRfbSrc:rfbsrc0: Error on setup VNC connection to host xx.xx.x.xx on port 5900Additional debug info:

                              Now there is a probleme with the VNC connection ?

                              I think no, because i did the same thing unsig tee and the connection looks ok, the stream is displayed, pressing ctrl+c i have the same output saying "Error on setup VNC connection to host..."

                              tee version (stream is displayed / file created but not readable ) :

                              gst-launch-1.0 -e rfbsrc host=xx.xx.x.xx port=5900 password=passw view-only=true
                              !  videoconvert

                                A silly question, did you try to read the file with gstreamer directly ?

                                  @SGaist hi!
                                  Yes, i had that idea only this morning.. Everything works almost as expected.

                                  This will Display / Record :

                                  gst-launch-1.0 -e rfbsrc host=xx.xx.x.xx port=5900 password=passw view-only=true !  videoconvert !  tee name = t t. ! queue ! openh264enc bitrate=4096  ! "video/x-h264, stream-format=(string)byte-stream" ! h264parse ! mp4mux ! filesink location=capture.mp4  sync=false t. ! queue ! autovideosink 
                                  

                                  This will read the recorded .mp4 file

                                  gst-launch-1.0 playbin uri=file:///c:/users/lev/documents/VNC_CLIENT_Tests/capture.mp4
                                  

                                  So everything works, but the video quality/ framerate are very bad... if something happends on the remote pc i have to wailt 2~3 secondes before i see it. Even with the official Viewer. I Abandon this solution, unless someone has a trick to highly optimize this.

                                  My first solution with your QVNCClient (it is made by you right ?) works much better with 15 ips capture.
                                  Then i reconstruct a video combining the images (even if simetimes i have desync of maximum 1 sec)

                                  Thank you again for your valuable help !

                                    Maybe another encoder could work better.

                                    No, QVNCClient is not from me, I just found it :)
