• Java ffmpeg cli wrapper : This binary is not a supported version of ffprobe

  5 juillet 2022, par Andrea Goldoni

  I need to use ffmpeg for one of my projects and I found this wrapper : https://github.com/bramp/ffmpeg-cli-wrapper . I've been trying to run it for a few days now, but I keep getting this error at runtime and I don't know how to fix it :

  


  

  


  I'm on Ubuntu 20.04.4 and I installed ffmpeg from the command line and I have static version 5.0.1. I've tried installing earlier versions, but if I do I get another runtime error saying I don't have permissions to run the program.
  
That's my code :

  


  import net.bramp.ffmpeg.FFmpeg;
import net.bramp.ffmpeg.FFmpegExecutor;
import net.bramp.ffmpeg.FFprobe;
import net.bramp.ffmpeg.builder.FFmpegBuilder;
import net.bramp.ffmpeg.probe.FFmpegProbeResult;

import java.io.IOException;

public class Main {
    public static void main(String argv[]) throws IOException {
        FFmpeg ffmpeg = new FFmpeg("/usr/local/bin/ffmpeg");
        FFprobe ffprobe = new FFprobe("/usr/local/bin/ffmpeg");
        String inFilename = "/home/andreag/Desktop/ffmpegWithJar/src/resources/input.mp4";
        FFmpegProbeResult in = ffprobe.probe(inFilename);

        FFmpegBuilder builder =
                new FFmpegBuilder()
                        .setInput(inFilename) // Filename, or a FFmpegProbeResult
                        .setInput(in)
                        .overrideOutputFiles(true) // Override the output if it exists
                        .addOutput("/home/andreag/Desktop/ffmpegWithJar/src/resources/output.mp4") // Filename for the destination
                        .setFormat("mp4") // Format is inferred from filename, or can be set
                        .setTargetSize(250_000) // Aim for a 250KB file
                        .disableSubtitle() // No subtiles
                        .setAudioChannels(1) // Mono audio
                        .setAudioCodec("aac") // using the aac codec
                        .setAudioSampleRate(48_000) // at 48KHz
                        .setAudioBitRate(32768) // at 32 kbit/s
                        .setVideoCodec("libx264") // Video using x264
                        .setVideoFrameRate(24, 1) // at 24 frames per second
                        .setVideoResolution(640, 480) // at 640x480 resolution
                        .setStrict(FFmpegBuilder.Strict.EXPERIMENTAL) // Allow FFmpeg to use experimental specs
                        .done();

        FFmpegExecutor executor = new FFmpegExecutor(ffmpeg, ffprobe);

        // Run a one-pass encode
        executor.createJob(builder).run();

        // Or run a two-pass encode (which is slower at the cost of better quality
        executor.createTwoPassJob(builder).run();
    }
}


  


• avformat/hlsenc : Use HLS version 2 if rounded durations are enabled

  29 juin 2022, par Lucy

  avformat/hlsenc : Use HLS version 2 if rounded durations are enabled
  This allows for wider compatibility with older devices, such as those
  
  running iOS 3. The only difference between HLS version 2 and version 3 is
  
  that version 3 supports non-integer EXTINF values, and as such, we can
  
  default to version 2 if we're using whole-integer EXTINFs anyways, when
  
  `-hls_flags round_durations` is set.
  As this code seems to otherwise consistently use the lowest compatible
  
  version, this seems to fit in properly with existing behavior.
  Testing confirms with that this patch, HLS output can work all the way back
  
  to iOS 3.
