• youtube to mp3 conversion on server

  3 juin 2016, par user1610362

  I’m wondering how can this site process file so quickly youtube-mp3.org. Could i use xuggler and convert to mp3 without downloading flv ? Could i use youtube-mp3.org in my program in order to download mp3 file from some youtube link. I’m trying to make server in java that has these capabilities and i could accomplish that just by downloading file and converting to mp3 but that isn’t fast enough...

• Could you please guide me on how to play a single sample of an audio file in C# using FFmpeg ?

  11 juillet 2023, par hello world

  What is the recommended approach for playing a single sample of an audio file in C# using FFmpeg ? I would like to incorporate FFmpeg into my C# application to play a specific sample from an audio file. Could someone provide an example or guide me on how to achieve this ? Any help would be appreciated.

  


  using System;
using System.Diagnostics;

public class AudioPlayer
{
    private string ffmpegPath;

    public AudioPlayer(string ffmpegPath)
    {
        this.ffmpegPath = ffmpegPath;
    }

    public void PlayAudioSample(string audioFilePath, TimeSpan samplePosition)
    {
        // Prepare FFmpeg process
        Process ffmpegProcess = new Process();
        ffmpegProcess.StartInfo.FileName = ffmpegPath;
        ffmpegProcess.StartInfo.Arguments = $"-ss {samplePosition} -i \"{audioFilePath}\" -t 1 -acodec pcm_s16le -f wav -";
        ffmpegProcess.StartInfo.RedirectStandardOutput = true;
        ffmpegProcess.StartInfo.RedirectStandardError = true;
        ffmpegProcess.StartInfo.UseShellExecute = false;
        ffmpegProcess.StartInfo.CreateNoWindow = true;

        // Start FFmpeg process
        ffmpegProcess.Start();

        // Play audio sample
        using (var audioOutput = new NAudio.Wave.WaveOutEvent())
        {
            using (var audioStream = new NAudio.Wave.RawSourceWaveStream(ffmpegProcess.StandardOutput.BaseStream, new NAudio.Wave.WaveFormat(44100, 16, 2)))
            {
                audioOutput.Init(audioStream);
                audioOutput.Play();
                while (audioOutput.PlaybackState == NAudio.Wave.PlaybackState.Playing)
                {
                    System.Threading.Thread.Sleep(100);
                }
            }
        }

        // Wait for FFmpeg process to exit
        ffmpegProcess.WaitForExit();
    }
}


  


• Video duration huge number tried to run through ffmpeg but still got a different huge number

  12 novembre 2016, par jon

  I recorded a video on Twitch using streamlink, but sometimes when I get the video the video duration is completely off.

  For example, if the video is 6 hours long, I get a random number like 235:23:00 or sometimes I just get 00:00. While the video still works you can’t use the time bar because it’s such a large number. When it is 00:00, every time you try to scroll past it starts over.

  I tried to run it through ffmpeg and it did change the video duration. However, it is still abnormally large at 29:33:44. What could I be doing wrong ? Can someone start me off in the right direction ?
