Hello, maybe i'm not understand clear, or this is ffmpeg issue, bu when i'm trying to create slideshow from images which have different resolutions, i get this error:

Error: Error: ffmpeg exited with code 1: Error configuring complex filters.
Invalid argument

(with one image and images with one resolution all is OK).

Can you help?)

little source code:

var videoshow = require('videoshow');
var fs = require('fs');
var images = [];
fs.readdirSync('./images').forEach((fileName) => {
  images.push('./images/' + fileName);
});
videoshow(images)
  .save('./result/result.mp4')
  .on('start', function (command) {
    console.log('ffmpeg process started:', command)
  })
  .on('error', function (err) {
    console.error('Error:', err)
  })
  .on('end', function (output) {
    console.log('Video created in:', output)
  });

Hi, i like your tool, it is exactly what i need at the moment.
I want to make a 4k (2160p) presentation - the images are already in the correct (exactly the same) resolution.
Everything works fine when I use the default 640x? resolution but once i increase it to 3840x? it crashes with:

used ffmpeg:

@h2non Do you have any steps I could undertake to further debug it or make it work?

Hi,

with this code I'm able to generate a .mp4

videoshow(filePaths, {size: '320x?'})
                .save("./video__"+base_Image+".mp4")
                .on('error', function (e) {
                    console.log("error mp4", e);
                })
                .on('end', function (e) {
                    console.log("end mp4");
                });

Chrome is capable to read it, Safari isn't.
Why?

This will improve the video customization features

I am using videoshow module to generate video but it is throwing error when i am running the module.
Here is the code which i am using :

createVideo: function(req,res,next) { 
    var images = [
          '1.jpg',
          '2.jpg',
          '3.jpg',
          '4.jpg'
    ]

    var videoOptions = {
      fps: 25,
      loop: 5, // seconds
      transition: true,
      transitionDuration: 1, // seconds
      videoBitrate: 1024,
      videoCodec: 'libx264',
      size: '640x?',
      audioBitrate: '128k',
      audioChannels: 2,
      format: 'mp4'
    }

    videoshow(images, videoOptions)
      .save('video.mp4')
      .on('start', function (command) {
        console.log('ffmpeg process started:', command)
      })
      .on('error', function (err, stdout, stderr) {
        console.error('Error:', err)
        console.error('ffmpeg stderr:', stderr)
      })
      .on('end', function (output) {
        console.error('Video created in:', output)
      })
}

When i am running the code it is showing the error below :

Error: [Error: Cannot find ffmpeg]
ffmpeg stderr: undefined

Hi

I created a series of images and want to convert it to a video with audio
140 images with 0.1 sec loop for each image
If audio is added the video comes out to be 14 seconds with last 20 images missing
If audio is NOT added the video comes out to be 16 seconds

Cant we have 14 second video with audio having all images

with ffmpeg I can create a video with images with multiple different dimensions calling this:

ffmpeg -r 30 -i %0d.jpg -vf "scale=1920:1080,format=yuv420p" -codec:v libx264 out.mp4

Is it possible to add the -vf "scale=1920:1080,format=yuv420p" to the videoshow command?
I tried to just pass to the options
filters: [{ filter: 'scale', options: [640, -1] }] but this did not worked, It still causes an error when passing images with different dimensions:

Error: [Error: ffmpeg exited with code 1: Error configuring complex filters. Invalid argument ]

Thanks for the amazing work on this!

If I wanted to just have the images be run in sequence at say 25fps, how would I go about doing that? I cannot seem to disable the loop option, and setting it's value to something like 1/25 (or 0.04), the resulting video is borken.

Like using melt: https://www.youtube.com/watch?v=3PRZ9L_KLdI

Is there any limit of images that the videoshow can process, because i am processing images more than 600 everytime. When i am trying to do this, i am getting the following error after 3-4 mins.

[Error: ffmpeg exited with code 1: Error while opening decoder for input stream #409:0 : Resource temporarily unavailable

If you cannot replicate this, let me know what information you need from me.

Thanks!

Noticed in your readme that you mentioned their was .gif support - but not sure if that included animated gifs.

I tried changing your audio example to include the chuck norris gif:

But i get the following error:

$ node audio.js 
Error: Error: ffmpeg exited with code 1: Option loop not found.

Is there something else i need to change? or is this not supported. Thnks!

I am unable to specify -pix_fmt as a video option. Which makes the video that i create not working on quick time player

Hi h2non,

Thanks for this wonderful script. I'd like to add intro/outro video clips to my videoshows.
I tried to use the input() method but with no luck. Here is what I tried :

var intro = "shared/intro.mp4";
var logo = 'shared/logo.png';
var mp3File = rootFolder + 'myAudio.mp3';
var loopTime = 15;
var images = [
  'step_1.png',
  'step_2.png',
  'step_3.png'
];
var videoOptions = {
      fps: 25,
      loop: loopTime, // seconds
      //loop: 5, // seconds
      transition: true,
      transitionDuration: 1, // seconds
      videoBitrate: 1024,
      videoCodec: 'libx264',
      size: '640x?',
      audioBitrate: '128k',
      audioChannels: 2,
      format: 'mp4'
    }

    var audioParams = {
      fade: true,
      delay: 2 // seconds
    }
videoshow(images, videoOptions)
  .input(intro)
  .audio(mp3File, audioParams)
  .logo(logo)
  .save(rootFolder + 'video.mp4')
  .on('start', function (command) {
    console.log('ffmpeg process started:', command)
  })
  .on('error', function (err, stdout, stderr) {
    console.error('Error:', err)
    console.error('ffmpeg stderr:', stderr)
  })
  .on('end', function (output) {
    console.error('Video created in:', output)
  })

The file runs smoothly however, the intro is not appended to the begginning as I had expected. Here is log (some filenames might have changed since I adapted the example for readability purposes) :

Hi. Thanks for the awesome library. I can create videos just fine but since I'm creating these dynamically, I'd like a way to make the audio loop if the video turns out to be longer than the audio duration. Is that possible?

I am trying to use videoshow with images of different dimensions and I'm getting the error:

Error: Error: ffmpeg exited with code 1: Error reinitializing filters!
Failed to inject frame into filter network: Invalid argument
Error while processing the decoded data for stream #2:0
Conversion failed!

I'm wondering how to incorporate the complex filters that you suggested on another forum OR how I can go about this another way.

The issue has been troubling me for weeks.

Does it support, or if not, it would be nice to support ffmpeg's image2pipe and be able to pipe a stream of images from another process (that maybe generate them dynamically) directly instead of reading images from disk.

Thank you very much, I have run the videoshow successfully, and if I want to add the zoom in zoom out effect for each exam image how to run the videoshow ... Thank you so much

I can't change transistion effect, there was only fade in and fade out but I have to do different one. Like as

 {
    path: '0.png',
 filter:zoompan=z='min(zoom+0.0015,1.5)':d=700:x='if(gte(zoom,1.5),x,x+1/a)':y='if(gte(zoom,1.5),y,y+1)':s=640x360`,
   }, 

or :

blend=all_expr='A_(if(gte(T,0.5),1,T/0.5))+B_(1-(if(gte(T,0.5),1,T/0.5)))'

Hi
I created a video using videoshow and video is playing on laptop but not on mobile
The parameters provided are below

                fps: 25,
                loop: 0.1, // seconds
                transition: false,
                videoBitrate: 1024,
                videoCodec: 'libx264',
                size: '640x?',
                audioBitrate: '128k',
                audioChannels: 2,
                format: 'mp4'

I am new in node.js , I want to create web application which takes images and audio and will generate video corresponding to that.
I have view your videoshow and thought that is best suited for my need but can you guide me how to implement that code for dedicated purpose.

Kindly response as soon as possible as I am already very late

ffmpeg exited with code 1: Error reinitializing filters!

On this page of the ffmpeg docs, it indicates there are several presets for render configs that affect speed.

I am using videoshow in a personal project and have noticed extremely long render times, up to 20 minutes for a 6 minute video, etc. How is it possible to use one of these speed presets with videoshow?

Thanks.

How to fix this ?

When running videoshow on a batch of square .jpgs to produce a video... i very rarely (1 in 50) get the above critical error using the SAME test data. Can anyone help with this? It's so intermittent but devastating when it occurs.

More featured than subrip

hi.I'm from project operates example, and audio.js no problem,but captions.js example throw new Error('No input specified'). can you help me? by the way.I have and demand is image turning the video.Image requires animation effects, not only effects that fade in shallow.
