  • How to create a video from image buffers using fluent-ffmpeg ?

    23 juin 2016, par Zacky Pickholz

    I’ve been trying to create a slideshow from a series of images using nodejs + fluent-ffmpeg, however it is not working well or consistently. ffmpeg occasionally emits "Error : ffmpeg exited with code 1 : pipe:0 : Invalid data found when processing input", and in case an eventual video (mp4) is created it seems to be missing images/frames.

    The process is as follows : images are loaded into memory, transformed resized to same dimensions using lwip, written sequentially into a passthrough stream, which is fed to ffmpeg as input.

    Relevant code snippets :

    var lwip = require('lwip');
    
var ffmpeg = require('fluent-ffmpeg');
    
var stream = require('stream');
    
var imagesStream = new stream.PassThrough();
    

    
...
    

    
image.batch()
    
            .contain(options.video.width, options.video.height, 'lanczos')
    
            .toBuffer(options.frames.format, {quality: 100}, (err, buffer) => {
    
                if (err) {
    
                    throw ('error convering image to buffer. ' + err);
    
                }
    
                imagesStream.write(buffer, 'utf8');
    
                resolve();
    
            });
    

    
...
    

    
    ffmpeg(imagesStream)
    
        .inputOptions('-framerate 1/' + options.frames.secsPerImage)
    
        .input(path.join(AUDIO_ROOT, options.audio.track))
    
        .save(path.join(path.join(OUTPUT_FOLDER, `${options.video.output.prefix}${timestamp}.${options.video.output.format}`)))
    
        .size(`${options.video.width}x${options.video.height}`)
    
        .on('start', () => {
    
            console.log('creating the clip now...')
    
        })
    
        .on('progress', (progress) => {
    
            var progPercent = Math.round(100 * progress.frames / (numImages * options.frames.secsPerImage * 25));
    
            progPercent = Math.min(progPercent, 100);
    
            console.log(`processing: ${progPercent}% done`)
    
        })
    
        .on('stderr', (line) => {
    
            console.error('ffmpeg error: ' + line);
    
        })
    
        .on('error', (error) => {
    
            reject('ffmpeg transcoding error: ' + error);
    
        })
    
        .on('end', () => {
    
            console.log('done!');
    
            resolve(true);
    
        })
    
        .run();

    And here is the output :

  • ffmpeg conversion using libx264 looks terrible - interlaced

    17 juin 2016, par justin

    I’m in the process of converting some files from my set-top box (.ASF) format to something more portable that will work with plex and roku more readily. In doing so I’m using ffmpeg, but having unsatisfying results. Whereas the original doesn’t have ANY notable interlacing defects, the converted file does. I think it has something to do with the libx264 converter because of the following experiment :

    Running this command :

    ffmpeg -i file.asf -vcodec copy -acodec copy -bsf:a aac_adtstoasc -ss 150 -t 15 short.mp4

    Produces a file which has quite a bit of interlacing defect when playing on my HD projector thru Roku via Plex (direct play enabled, apparently no transcoding).

    still frame from second transcode showing visual defect

    Lest I be overly picky, I engaged my wife in this test, showing her the two files and she agreed that the one that used libx264 was significantly worse and unwatchable. Can’t figure out how to shrink this file down without causing these interlacing defects — it happens even when I don’t try to shrink it ! Any thoughts ?

    Video files :

    https://dl.dropboxusercontent.com/u/23091/m1/short.mp4
    https://dl.dropboxusercontent.com/u/23091/m1/short2.mp4

    Update : Additionally, I tried a few settings to generate a MPEG4 (.AVI) file and had similar lack of success. Similar interlacing defects.
