• Cannot set duration for one image while converting images to mp4 using ffmpeg

  20 février 2023, par Peter.k

  I can't set duration for single image in the video. There are 24 images from here :
http://luna1.diviner.ucla.edu/~jpierre/diviner/level4_polar/hourly_maps/south/polar_south_80_summer_tbol-hour" named in for each %02d.png (concat this to get links). I use code

  


  ffmpeg -i e:\gals\moon\polar_south_80_summer_tbol-hour%02d.png -t 0.2 -r 5 -vcodec mpeg4 e:/test.mp4


  


  and always get 1 second video, but I need to have 0.2 seconds for each image, hence the whole video should be 4.8s. Someone in different threat say I need to set -framerate 5, to get 0.2s for each image, but this doesn't work. I use many variants of parameters : -d 4.8 -r 5, or -t 4.8 -r 5, or -r 24, and always get 1s of the whole video. Setting -loop 1 gets desired lenght, but it loops many times wrongly framed images.

  


  Please give me some advice.

  


• fluent-ffmpeg concatenate audio files

  8 septembre 2020, par Martin

  I am trying to use fluent-ffmpeg with my electron app to concatenate multiple audio files together with an image in a video. So if i have three files :

  


  song1.mp3 1:00
song2.mp3 0:30
song3.mp3 2:00
front.jpg

  


  I could create output.mp4 which would be 3:30 seconds long, and play each file one after the other in order. With front.jpg set as the background image.

  


  I have succesfully been able to render a single audio file with an image file, but havent been able to render multiple audio files together yet into a video.

  


  Here is my concat attempt :

  


  const command = ffmpeg();
       
            const audioFiles = ['C:\\Users\\marti\\Documents\\martinradio\\uploads\\Movers - 1970 greatest hits vol. 2\\01 back from the moon.mp3', 'C:\\Users\\marti\\Documents\\martinradio\\uploads\\Movers - 1970 greatest hits vol. 2\\02 love me not.mp3'];
            audioFiles.forEach((fileName)=>{
                command.input(fileName);
            })
            command
                    .complexFilter([
                        '[0]adelay=1000|1000[a]',
                        '[1]adelay=4000|4000[b]',
                        '[a][b]amix=2'
                    ])
                    .input(imgPath)
                    .videoCodec('copy')
                    .save('C:\\Users\\marti\\Documents\\martinradio\\uploads\\Movers - 1970 greatest hits vol. 2\\concat-autio.mp4')
                    .on('codecData', function(data) {
                        console.log('codecData=',data);
                    })
                    .on('progress', function({ percent }) {
                        console.log('progress percent: ' + percent);
                    })
                    .on('end', function() {
                        console.log('file has been converted succesfully');
                    })
                    .on('error', function(err) {
                        console.log('an error happened: ' + err.message);
                    })
                    command.run()


  


  When I run it I can see in my console it start, run, and end.

  


  

  


  My example uses two audio files :

  


  01 back from the moon.mp3 02:31
02 love me not.mp3' 02:35

  


  So my output file should be 05:06 in length, but my output is only 02:39 in length
