• Unable to Record Video in Jenkins using ffmpeg in Windows System

  12 novembre 2018, par Deepak Kumar Susarla

  I am using ffmpeg to capture video while running protractor scripts. Below ffmpeg code is working fine, when I directly run in windows from command line and able to create the video.

  C:\Jenkins\workspace\test\node_modules\ffmpeg-binaries\bin\ffmpeg.exe -f gdigrab -framerate 30 -s 1024x768 -i desktop -g 1000 -q:v 18 C:\Jenkins\workspace\test\AutomationVideo\Automation-11-7-2018-17.6.23.mpg

  But when I run the same code through jenkins(installed in windows system), showing below error and video is not getting recorded. Please help me in resolving the issue.

  error is :[gdigrab @ 000002395689b400] Capturing whole desktop as 1024x768x32 at (0,0)

  error is :[gdigrab @ 000002395689b400] Failed to capture image (error 5)

• The System Audio not included when recording screen using tab capture api

  21 septembre 2024, par alpecca

  I am working on a chrome extension that let user record their current tab video + the current system audio for example playing a music on the tab. I read the docs on the web about preserve audio on tab capture api and the audio constraint to set to be true

  


  chrome.tabCapture.capture({
        video: true,
        audio: true,


  


  const stream = await new Promise<mediastream null="null">((resolve, reject) => {&#xA;    chrome.tabCapture.capture({&#xA;        video: true,&#xA;        audio: true,&#xA;        videoConstraints: {&#xA;            &#xA;            mandatory: {&#xA;                minFrameRate: 60,&#xA;                maxFrameRate: 60,&#xA;                minWidth: 1920, &#xA;                minHeight: 1080, &#xA;                maxWidth: 1920,&#xA;                maxHeight: 1080,&#xA;            }&#xA;        }&#xA;    }, (stream: MediaStream | null) => {&#xA;        if (chrome.runtime.lastError) {&#xA;            return reject(new Error(chrome.runtime.lastError.message));&#xA;        }&#xA;        resolve(stream);&#xA;    });&#xA;});&#xA;</mediastream>

  


  In the above code, when I set the audio to be true and try to record the screen, the final output doesn't contain any audio.

  


  Here is the Media Recorder values :-

  


  const recorder = new MediaRecorder(stream, {
            mimeType: 'video/webm;codecs=H264',
            videoBitsPerSecond: 8000000
        });

        recorder.ondataavailable = (e: BlobEvent) => {
            socketRef.send(e.data)
           
        }
  
        recorder.start(2000);


  


  And also my ffmpeg in the backend to handle the incoming stream :-

  


  command = [
        'ffmpeg', 
        '-y',
        '-i', 
        '-', 
        '-codec:v', 
        'copy', 
        '-codec:a', 
        'copy', 
        '-y',
        '-f', 'mp4',
        recordingFile,
        # "-"
        # f'output{queueNumber}.mp4',
    ]


  


  Any help would be greatly appreciated :)
