• ffmpeg Installation Error Through Homebrew

  19 décembre 2022, par Bob Bob

  I was looking to download ffmpeg to convert some mp4/mp3 files in python but was met with an error I could not find the solution for elsewhere.

  


  When attempting to install ffmpeg on terminal, I was met by this error.

  


  fatal: Could not resolve HEAD to a revision Warning: No available formula with the name "ffmpeg". ==> Searching for similarly named formulae... Error: No similarly named formulae found. ==> Searching for a previously deleted formula (in the last month)... Error: No previously deleted formula found. ==> Searching taps on GitHub... Error: No formulae found in taps.

  


  I was expecting everything to work perfectly but obviously it hasn't. I looked into other users that had similar errors and went through what they did to solve their problems but was not able get anything to work out.

• ffmpeg fluent 'Error initializing complex filters'

  15 février 2018, par Ricky

  I am trying to create a complex filter based on the images the user has chosen in the app however ffmpeg fluent is outputting

  "ffmpeg exited with code 1 : Error initializing complex filters."

  This is the code in question :

  let streamYT = (YTrtmp) => {
  
    let L = logosInUse.length
  
    let location = logoHorizontal + ":" + logoHeight
  
    let scale = imgScale
  
  
  
    let formula = null
  
    let accr = altTime*2
  
    let accr2 = accr
  
    for(var i=0; i<(L + 1); i++) {
  
        if(i === 1){
  
            formula = "["+ i +"]scale="+ scale+"[ovrl" + i +"], [v"+ (i - 1) +"][ovrl" + i + "] overlay=" + location +":enable='lt(mod(t,"+ (L * altTime)+"),"+ altTime+")'[v"+i+"];"
  
        }
  
        if(i === 2){
  
            formula = formula + "["+ i +"]scale="+ scale+"[ovrl" + i +"], [v"+ (i - 1) +"][ovrl" + i + "] overlay=" + location +":enable='between(mod(t,"+ (L * altTime)+"),"+ altTime+","+accr+")'[v"+i+"];"
  
        }
  
        if(i === 3){
  
            formula = formula + "["+ i +"]scale="+ scale+"[ovrl" + i +"], [v"+ (i - 1) +"][ovrl" + i + "] overlay=" + location +":enable='gt(mod(t,"+ (L * altTime)+"),"+ accr +")'[v"+i+"];"
  
        }
  
        if(i > 3){
  
            accr2 = accr2 + altTime
  
            formula = formula + "["+ i +"]scale="+ scale+"[ovrl" + i +"], [v"+ (i - 1) +"][ovrl" + i + "] overlay=" + location +":enable='gt(mod(t,"+ (L * altTime)+"),"+ accr2 +")'[v"+i+"];"
  
        }
  
    }
  
    if(formula !==  null){
  
      formula = formula.slice(0, -5)
  
      }
  
    let listOfLogos = ''
  
    for(n in logosInUse){
  
    listOfLogos = listOfLogos + ".input('./public/images/" + logosInUse[n] + ")" 
  
    }
  
  
  
    console.log("streaming to youtube")
  
    var proc3 = new ffmpeg({ source: inputURL, timeout: 0 })
  
      .addOption('-vcodec', 'libx264')
  
      .addOption('-acodec', 'aac')
  
      // .addOption('-crf', 26)
  
      .addOption('-f', 'flv')
  
      // .addOption('-vf', "scale=" +  resolution)
  
      .complexFilter('"' + formula + '"')
  
      .on('start', function(commandLine) {
  
      console.log('Query : ' + commandLine);
  
      })
  
      .on('error', function(err) {
  
      console.log('Error: ' + err.message);
  
      })
  
      .output('rtmp://a.rtmp.youtube.com/live2/' + YTrtmp, function(stdout, stderr) {
  
        console.log('Convert complete' +stdout)
  
      })
  
  
  
      for(n in logosInUse){
  
        proc3 = proc3.input('./public/images/' + logosInUse[n])
  
        }
  
      // proc3 =  proc3.input("./public/images/red.jpg")
  
      proc3.run()
  
    }

  formula outputs

  [1]scale=40:40[ovrl1], [v0][ovrl1] 
  
  overlay=580:10:enable='lt(mod(t,40),10)'[v1];[2]scale=40:40[ovrl2], [v1]
  
  [ovrl2] overlay=580:10:enable='between(mod(t,40),10,20)'[v2];
  
  [3]scale=40:40[ovrl3], [v2][ovrl3] 
  
  overlay=580:10:enable='gt(mod(t,40),20)'[v3];[4]scale=40:40[ovrl4], [v3]
  
  [ovrl4] overlay=580:10:enable='gt(mod(t,40),30)'[v4];

  and the query outputs

  ffmpeg -i https://mnmedias.api.telequebec.tv/m3u8/29880.m3u8 -i 
  
  ./public/images/crunchy.png -i ./public/images/logo2.jpg -i 
  
  ./public/images/red.jpg -i ./public/images/ACE.png -filter_complex "
  
  [1]scale=40:40[ovrl1], [v0][ovrl1] 
  
  overlay=580:10:enable='lt(mod(t,40),10)'[v1];[2]scale=40:40[ovrl2], [v1]
  
  [ovrl2] overlay=580:10:enable='between(mod(t,40),10,20)'[v2];
  
  [3]scale=40:40[ovrl3], [v2][ovrl3] 
  
  overlay=580:10:enable='gt(mod(t,40),20)'[v3];[4]scale=40:40[ovrl4], [v3]
  
  [ovrl4] overlay=580:10:enable='gt(mod(t,40),30)'" -vcodec libx264 -acodec 
  
  aac -f flv rtmp://a.rtmp.youtube.com/live2/2222-2222-2222-2222

  Which runs fine when I plug it into my console directly. Can’t understand where I am going wrong here.
