seeking with av_seek_frame returns invalid data
27 juin 2016, par mtadmkBased on dranger tutorial I’m trying to implement seeking in video file. Problem is with seeking to beginning milliseconds - it always returns 0 when seeking backward, or some place in file (based on file format).
I.e. with this video file and seeking forward to 500 pts there is always 6163 pts returned. Seeking backward to 500 is always returning 0. I have no idea why.
Code to do this :

How to create a video from image buffers using fluent-ffmpeg ?
23 juin 2016, par Zacky PickholzI’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 :

Encoding Exception during Transcode with audio files
6 mai 2016, par Hakop ZakaryanI am attempting to transcode using an FFMPEG Wrapper Library called JAVE on Mac OSX 10.11.3 using Eclipse 4.50
My Converter.java class looks something like this :
package matador;
import it.sauronsoftware.jave.AudioAttributes;
import it.sauronsoftware.jave.EncodingAttributes;
import it.sauronsoftware.jave.EncoderException;
import it.sauronsoftware.jave.InputFormatException;
import it.sauronsoftware.jave.Encoder;
import java.io.*;
public class Converter {
public static void main(String[] args) throws InputFormatException, EncoderException {
File source = new File("Classic.m4a");
File target = new File("target.mp3");
AudioAttributes audio = new AudioAttributes();
audio.setCodec("libmp3lame");
audio.setBitRate(new Integer(128000));
audio.setChannels(new Integer(2));
audio.setSamplingRate(new Integer(44100));
EncodingAttributes attrs = new EncodingAttributes();
attrs.setFormat("mp3");
attrs.setAudioAttributes(audio);
Encoder encoder = new Encoder(new MyFFMPEGExecutableLocator());
try {
encoder.encode(source, target, attrs, null);
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (InputFormatException e) {
e.printStackTrace();
} catch (EncoderException e) {
e.printStackTrace();
}
}
}The problem I am running into is that with specific audio files (regardless of format) give me this EncoderException :
it.sauronsoftware.jave.EncoderException: Metadata:
at it.sauronsoftware.jave.Encoder.encode(Encoder.java:863)
at matador.Converter.main(Converter.java:32)I have looked through Encoder.java and the EncoderException on line 863 is this specific code :
} else if (!line.startsWith("Output #0")) {
throw new EncoderException(line);I have been unable to figure out why this may be occurring but specific audio files (WAV/AAC/etc) do encode yet a majority just give this exception.
Thank you for the help !
