  • ffmpeg & png watermark issue

  I’m trying to create a NodeJS app that converts a video into a GIF image.

  I’m using node-gify plugin for this purpose, which uses FFmpeg and GraphicsMagick.

  Here’s my sample code :

  var gify = require('./');
  
  var http = require('http');
  
  var fs = require('fs');
  
  
  
  var opts = {
  
    height: 300,
  
    rate: 10
  
  };
  
  
  
  console.time('convert');
  
  gify('out.mp4', 'out.gif', opts, function(err) {
  
    if (err) throw err;
  
    console.timeEnd('convert');
  
    var s = fs.statSync('out.gif');
  
    console.log('size: %smb', s.size / 1024 / 1024 | 0);
  
  });

  And here’s my console error :

  > gify@0.2.0 start /home/daffodil/repos/node-gify-master
  
  > node example.js
  
  
  
  /home/daffodil/repos/node-gify-master/example.js:24
  
    if (err) throw err;

  PS : I had a couple of problems installing FFmpeg on my Ubuntu 14.04.

  • First, FFmpeg is removed from Ubuntu 14.04 (legal issues AFAIK). But I managed to apt-get it through this.
  • Second, when I tried to ./configure (as mentioned in its README.md), I got this error - yasm/nasm not found or too old. Use --disable-yasm for a crippled build.. So I used ./configure --disable-yasm instead, and it (somehow) worked.

  Update #1

  After read this log a couple of times, I managed to produce a sample GIF from my mp4 file, by changing the command, which example.js tries to run :

  From

  ffmpeg -i out.mp4 -filter:v scale=-1:300 -r 10 /tmp/Lz43nx6wv1/%04d.png

  To

  ffmpeg -i out.mp4 -filter:v scale=-1:300 -r 10 out.gif

  But it’s still using command line, I need to do this by code.

  So I dived into the code and found that this wrong url is coming from the plugin’s index.js :

  ...
  
  
  
  // tmpfile(s)
  
    var id = uid(10);
  
    var dir = path.resolve('/tmp/' + id);
  
    var tmp  = path.join(dir, '/%04d.png');
  
  
  
  ...

  Is this an issue with the plugin, or am I doing something wrong here ?
  In any case, please put the correct stub here, because I don’t want to touch this part unless I know what I’m doing ?

  Update #2

  Now I installed zlib1g-dev, and then reinstalled both FFmpeg and graphicsMagick, and now I see this error :

  gm convert: No decode delegate for this image format (/tmp/ZQbEAynAcf/0702.png).

  Thanks in advance :)

• Images to video in Prezi format

  13 juin 2016, par sammy34

  I have five *.jpeg image files : m01.jpeg to m05.jpeg.

  I’d like to make a video of a sequence of these five images and upload it to Prezi to use in a presentation.

  FFMPEG seems to be the tool for the job here. I am generating a video using the following command :

  ffmpeg -r 2 -i m%02d.jpeg -pix_fmt yuvj420p myvideo.mp4

  This generates a video that I can play fine locally. Unfortunately, when I try to upload the video to Prezi, I always get the following error...

  "Technical details: id: 2110 the reason is: Event [Event type="stateChange" bubbles=false cancelable=false eventPhase=2]"

  ...which isn’t particularly informative.

  If I upload a sample MP4 from the web to Prezi, it works fine.

  My question : Does anybody know what I need to give FFMPEG as parameters here so that it will generate a Prezi-compatible video from these images ?

  EDIT : As requested, here’s the complete console output for FFMPEG. Unfortunately there are no glaring warnings or errors that I can see.

• FFMPEG rotates images

  13 juin 2016, par Jaketr00

  I am trying to mass-resize images using FFMPEG, and I successfully did it using bash, but I noticed that some of the portrait images got rotated to landscape. Here is the original image, but as you see below, it gets rotated.

  

  As you see above, the image is rotated. At first, I thought this was due to the -vf scale flag that I was using to resize the images, but I tried the following command and it still rotated the image.

  ffmpeg -i input.jpg output.jpg

  This doesn’t happen with every image, and even not all the portrait images. Also, some images rotate clockwise, while some rotate counter-clockwise. And this isn’t a random occurrence, all the images that originally rotated still rotate no matter how many times I run the command.
