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

SGaist

@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 ?

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 ?

ODБOï

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

ODБOï

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:

An error happened while waiting for EOS
Execution ended after 0:00:07.166707941
Setting pipeline to PAUSED ...
Setting pipeline to READY ...
Setting pipeline to NULL ...
Freeing 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
! queue 
! openh264enc bitrate=4096  
! "video/x-h264, stream-format=(string)byte-stream"
! h264parse 
! mp4mux
! filesink location=video.mp4  sync=false 
t. 
! queue 
! autovideosink

SGaist

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

ODБOï

@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 !

[edit: fixed link SGaist]

SGaist

Maybe another encoder could work better.

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