• Empty error object produced by ffprobe in Google Cloud Function

  20 septembre 2023, par willbattel

  Update : After more digging I found an open GitHub issue where others appear to be encountering the same behavior.

  


  ---

  


  I have a Google Cloud Function (2nd gen) in which I am trying to use ffprobe to get metadata from a video file stored in a Google Cloud Storage bucket. It is my understanding that I can generate a signed url and, by passing that directly to ffprobe, avoid loading the entire video file into memory. I generate a signed url and pass it to ffprobe, and then parse the output like so :

  


  import ffmpeg from 'fluent-ffmpeg'
import ffprobeStatic from 'ffprobe-static'

async function getVideoData(srcFile: File) {
    const [signedUrl] = await srcFile.getSignedUrl({
        action: 'read',
        expires: (new Date()).getMilliseconds() + 60_000,
    })

    const videoData: ffmpeg.FfprobeData = await new Promise((resolve, reject) => {
        ffmpeg.setFfprobePath(ffprobeStatic.path)
        ffmpeg.ffprobe(signedUrl, (err, data) => {
            if (err) {
                reject(err)
            }
            else {
                resolve(data)
            }
        })
    })

    return videoData
}


  


  This code works (with the same signed URL) locally on my macOS machine, but does not when deployed in a 2nd generation Google Cloud Function. In the latter case, data is undefined and err is {}.

  


  My main question is how to properly use ffprobe in 2nd gen Google Cloud Functions. I have tried to research this but documentation on ffmpeg/ffprobe on GCP is sparse. I'm also trying to figure out exactly why the error object err is empty...it's not very helpful 😅

  


  Additional info :

  


  

  • Environment : Google Cloud Functions 2nd Gen

  


  • Runtime : Node 20

  


  • "ffprobe-static" : "3.1.0",

  Thanks in advance.

  


• ffmpeg -pattern_type glob not working in Google Colab

  22 février 2023, par John Jannone

  I'm trying to combine images into video using ffmpeg in a Google Colab Notebook ; I'm getting errors but don't see what I'm doing wrong.

  


  !ffmpeg -pattern_type glob  -i 2023021522* -c:v libx264 video2.mp4

  


  returns : Option pattern_type not found.

  


  !ffmpeg -pattern_type glob  -i '2023021522*' -c:v libx264 video2.mp4 or
!ffmpeg -pattern_type glob  -i "2023021522*" -c:v libx264 video2.mp4

  


  return : 2023021522* : No such file or directory

  


  I also tried adding from glob import glob and just import glob

  


• Is there a way to add watermark to all videos in Google Drive’s folder ?

  Is there a way to add watermark to all videos in Google Drive’s folder ?

  I found similar service, but it works only with pictures, pdfs - Wappwolf

  Maybe, it’s possible to do by Google Apps Script or some other services (like ffmpeg) ?
