• Complex, how to -o, -mv or similar into this code ? [closed]

  13 décembre 2020, par Sounds Good

  Trying to change location of output file
Using Windows>Ubuntu app>Shell/Cmd>Bash (because Windows alone code does not work at all)
Using Ffmpeg/Youtube-dl/Sed together
It works on its own :

  


  ffmpeg $( youtube-dl -f bestvideo+bestaudio --youtube-skip-dash-manifest -g https://www.youtube.com/watch?v=zSyNOO_gvUY | sed "s/.*/-ss 04:09 -to 04:15 -i &/") -map 0:v -map 1:a -c:v libx264 -c:a aac name.mp4

  


  Bash starts as : :/mnt/c/Users/Machine$

  


  Fallowing just few of many problems I tried to figure out for this :

  


  should I use / or \ to "subfolder"

  


  Start from / or C or Desktop etc.

  


  does -o need to be configured and if so how

  


  placements after Youtube-dl or in the ending by keeping name.mp4 or not, or changing it to
'-o %(title)s.%(ext)s' (title change needed as well thought)

  


  help.

  


• 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();
    }
}
