• Getting this error in ffmpeg pipeline : Non-monotonous DTS in output stream 0:0 ; previous : 4951970, current : 4951659 ; changing to 4951971

  Error : Non-monotonous DTS in output stream 0:0 ; previous : 4951970, current : 4951659 ; changing to 4951971. This may result in incorrect timestamps in the output file.

  


  I am using AWS Chime streaming then passing there data stream to FFMPEG and then going live with that data stream using AWS IVS(Interactive video service).
I am using ffmpeg for changing aspects of video on live streaming and brightness and contrast.
But when we turn off camera and after some time reopen it we facing the above mention error.
I have read about concat but we don't have input file actually we are passing data stream is ffmpeg that's why its not working.

  


  Here is my ffmpeg command

  


  ffmpeg=ffmpeg.spawn('ffmpeg', [
            '-i', '-' ,
            // '-f', 'concat',
            // '-segment_time_metadata','1',
            // '-use_wallclock_as_timestamps', '1',
            '-c:v', 'libx264',
            '-b:v', '2567k',
            '-maxrate', '6000K',
            '-preset', 'ultrafast',
            '-profile:v', 'baseline',
            '-level', '3.0',
            // '-aspect', '9:16',
            '-force_key_frames', 'expr:gte(t,n_forced*2)',
            '-movflags', 'faststart',
            '-fflags', 'nobuffer',
            '-tune', 'zerolatency',
            '-acodec', 'aac',
            '-ab', '160k',
            '-ar', '44100',
            '-f', 'flv',
            'rtmps-url/secret-key-replaced'
        ])


  


  I have tried this command -use_wallclock_as_timestamps', '1' but it does nothing to error.

  


• Application won't work after disconnecting from RDP [closed]

  12 juillet 2023, par Duri Eun

  The problem is that my Java Script runs perfectly fine when I have a connection with RDP to my Windows Server but when I disconnect (Clicking X) as title says my Script wont work as expected.

  


  It is recieving the requests from my website but can't do the tasks properly such as FFMpeg.

  


  


  Error adding banner to the video : Error : ffmpeg exited with code 1 :
at ChildProcess. (C :\Users\durieun02\Desktop\server\node_modules\fluent-ffmpeg\lib\processor.js:182:22)
at ChildProcess.emit (node:events:513:28)
at ChildProcess._handle.onexit (node:internal/child_process:291:12)

  


  


  This is just an explanation error, in reality my process is not even working.

  


  And such more errors like this when I am disconnected, The whole point of me opening a VM was to keep my actual PC offline while server would run for me in the background.

  


  I have also tried running my Script as a background process but it didn't worked either. It still somehow didn't have the permissions or something, not really sure why.

  


  I also edited gpedit.msc and Edited necessary things such as "Session Time Limits" but its not revelant at all since my session is not turning off but rather function don't work properly when RDP is not connected.

  


  I have also trying running it as a scheduled task and windows service, the problem is still same, the script runs but its not working as expected, my website esentiially returns the errors.

  


  Thanks for the helps, I hope we can find a solution for all.
