• Java Playing Sound From YouTube

  8 mai 2022, par etkmlm

  I'm in a LWJGL game and want to play sound from YouTube. I have the stream link but can't play it anymore.

  


  public void playMusic(Music m) throws IOException {
    String uri = m.getUrl();
    URL url = new URL(uri);
    try{
        Process p = new ProcessBuilder().command("ffmpeg.exe", "-i", uri, "-acodec", "pcm_u8", "-ar", "22050", "-f", "wav", "pipe:1").redirectError(ProcessBuilder.Redirect.INHERIT).start();

        AudioInputStream str = AudioSystem.getAudioInputStream(p.getInputStream());
        Clip clip = AudioSystem.getClip();
        clip.open(str);
        clip.start();

    }
    catch (Exception e){
        e.printStackTrace();
    }

}


  


  It throws "Chunk size too big" error. I started ffmpeg alone but in this time, ffmpeg throws "invalid argumentsize=" error.

  


• how to stream a website to youtube using ffmpeg with python [closed]

  22 avril 2023, par Eyal B

  I want to stream a website (more specifically an element) to YT using ffmpeg with python. i already found a way to stream an mp4, but now i want to stream a website. i thought of using a headless browser like puppeteer and selenium, but couldnt quite get it right.
the ffmpeg command that worked was : ffmpeg -re -i cat.mp4 -pix_fmt yuvj420p  -x264-params keyint=48:min-keyint=48:scenecut=-1  -b:v 4500k -b:a 128k -ar 44100 -acodec aac -vcodec libx264 -preset medium -crf 28 -threads 4 -f flv rtmp://x.rtmp.youtube.com/live2/waas-xbqw-d671-4a75-2qq2 thanks in advance !

  


• Stream PNG file to youtube with ffmpeg

  3 avril 2022, par codingmaster398

  What I'm trying to do :
I have a PNG file that is constantly getting written to. I want to pipe it (while it changes) to YouTube's RTMP server.

  


  What I've attempted :

  


  runCommand(
      'ffmpeg',
      `-threads:v 2 -threads:a 8 -filter_threads 2 -thread_queue_size 512 \
-loop 1 -re -i place.png \
-stream_loop -1 \
-filter:v "crop=in_w/2:in_h/2:1920:1280" \
-pix_fmt yuv420p -c:v libx264 -qp:v 19 -profile:v high -rc:v cbr_ld_hq -level:v 4.2 -r:v 60 -g:v 120 -bf:v 3 -refs:v 16 -preset fast -f flv rtmp://a.rtmp.youtube.com/live2/${steamKey}`,
    () => {},
    () => console.log('finished')
)

setInterval(()=>{
  image.write('./place.png') // Jimp },5000)


  


  What happens :
