    @LeLev You could try to play a video from a non-SSL (non-HTTPS) URL.

        Can please someone help me to complete this pipeline so it can record the VNC remote desktop to video file and/or show it with
        playbin ?
        pipeline = gst_parse_launch("rfbsrc host=xx.xx.xx.xx port=5900 password=passw view-only=true",NULL);

          Use the tee plugin.

            @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)

                            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

                                  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

                                    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 
                                    ! tee name = t

                                      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 :)
