    @LeLev said in GStreamer : understanding the concept of 'pipeline':

    GST_MESSAGE_ERROR | GST_MESSAGE_EOS

    this is the actual problem. Try to cast it to GstMessageType:

    msg = gst_bus_timed_pop_filtered(bus, GST_CLOCK_TIME_NONE, static_cast<GstMessageType>(GST_MESSAGE_ERROR | GST_MESSAGE_EOS));

      msg = gst_bus_timed_pop_filtered(bus, GST_CLOCK_TIME_NONE, GST_MESSAGE_EOS);

      @LeLev That's why it is important to post all errors: many errors are just follow up errors caused by another error.

        all errors

        saved for the next time.

        I'm confused about this lib.
        In this hello world exemple they say :

        If everything built fine, fire up the executable! You should see a window pop up, containing a video being played straight from the Internet, along with audio. Congratulations!

        I can't figure out how a window will pop up.
        I'm reading the playbin description right now, in my app nothing pops up.

          So, you start the app but no window pops up?
          Then probably something is wrong. I don't know what. You can debug and see what happens.

              @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)

                              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
