GStreamer : Pipeline to connect VNC server and Display/Record the remote GUI


  • Lifetime Qt Champion

    @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));
    


  • i just changed the 3rd parameter and it compiled

    msg = gst_bus_timed_pop_filtered(bus, GST_CLOCK_TIME_NONE, GST_MESSAGE_EOS);

    ry to cast it to GstMessageType:

    Thank you !


  • Lifetime Qt Champion

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



  • @jsulm said in GStreamer : understanding the concept of 'pipeline':

    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.

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

    I can't figure out how a window will pop 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.

    Yes,

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

    yes, with putenv("GST_DEBUG=2"); i got :

    i will install glib-networking


  • Lifetime Qt Champion

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



  • @jsulm That worked thank you!



  • 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);


  • Lifetime Qt Champion

    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

  • Lifetime Qt Champion

    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)

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

    gst-plugins-ugly but cant fugure out how to install tath missing plugin

    apt install gstreamer1.0-plugins-ugly
    


  • @jsulm hi ,
    I did not mension I'm using windows.


  • Lifetime Qt Champion

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

    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 ?

  • Lifetime Qt Champion

    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:

    Setting pipeline to PAUSED ...
    Setting pipeline to READY ...
    Setting pipeline to NULL ...

    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
    ! queue 
    ! openh264enc bitrate=4096  
    ! "video/x-h264, stream-format=(string)byte-stream"
    ! h264parse 
    ! mp4mux
    ! filesink location=video.mp4  sync=false 
    t. 
    ! queue 
    ! autovideosink

    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 :)
