• Am I able to stream .mp4 file with the appropriate stream key ?

  8 octobre 2022, par akumakan

  Expected Results :
Right now, this is the code that I am trying to edit. What this does is that I input a name (example.mp4) and it take the contents from a notepad with my stream keys and streams the .mp4 file I input. I want it so that I have .mp4 files with the names as stream keys and the program streams it with the appropriate stream key in the notepad. Is that possible ?

  


  Initial code :

  


  import subprocess

print("Enter the name of the file you want to stream. Include the file extension.\nExample: lofi.mp4 or image.png or pogchamp.gif")
filename = input("\nFilename: ")
with open('stream_keys.txt','r')as keys:
    for key in keys:
        subprocess.Popen(f'ffmpeg -stream_loop -1 -re -i {filename} -stream_loop -1 -i music.mp3 -c:v libx264 -preset veryfast -b:v 3000k -maxrate 3000k -bufsize 6000k -pix_fmt yuv420p -g 50 -c:a aac -b:a 160k -ac 2 -ar 44100 -f flv "rtmp://live.twitch.tv/app/{key}"', shell=True)


  


  What I tried :
Im not proficient with coding and i tried to change the filename into keys.mp4 thinking it will have my expected results.

  


  
print("Edit Names of .mp4 files with twitch stream keys")
open('stream_keys.txt','r')as keys:
    for key in keys:
        subprocess.Popen(f'ffmpeg -stream_loop -1 -re -i {key}.mp4 -stream_loop -1 -i music.mp3 -c:v libx264 -preset veryfast -b:v 3000k -maxrate 3000k -bufsize 6000k -pix_fmt yuv420p -g 50 -c:a aac -b:a 160k -ac 2 -ar 44100 -f flv "rtmp://live.twitch.tv/app/{key}"', shell=True)


  


  thank you

  


• How to pipe output of ffmpeg to three different processes ?

  19 juillet 2012, par Richard Knop

  How can I pipe output of ffmpeg without saving it to a file to three different processes ?

  Let's say I have :

  ffmpeg -i input.mpg output.yuv

  I would like to change that in order to avoid saving YUV to physical disk. I would like to pipe it to three different shell commands.

  How to do it ?

• Android ICS FFMPEG scale video not working

  20 avril 2015, par Android-Developer

  I am using Guardian Project Android Java FFMPEG library to resize videos. Current code which is working on android 5.0.1 / 5.1.0 / 4.4.4 :

      File fileTmp = getCacheDir();
  
      FfmpegController fc = null;
  
      try {
  
          fc = new FfmpegController(this, fileTmp);
  
      } catch (IOException e) {
  
          e.printStackTrace();
  
      }
  
      String path = Environment.getExternalStorageDirectory().getPath() + "/Movies/nexus.mp4";
  
      final String outPath = Environment.getExternalStorageDirectory().getPath() + "/Movies/test.mp4";
  
      final Clip out = new Clip(path);
  
      try {
  
          if (fc != null) {
  
              fc.convert(out, outPath, new ShellUtils.ShellCallback() {
  
                  @Override
  
                  public void shellOut(String shellLine) {
  
                      Log.e("", "SHELL OUT: " + shellLine);
  
                  }
  
  
  
                  @Override
  
                  public void processComplete(int exitValue) {
  
                      Log.e("", "PROCESS COMPLETE: " + exitValue);
  
                  }
  
              });
  
          }
  
      } catch (Exception e) {
  
          e.printStackTrace();
  
      }

  Using this code on Android 4.0.4 (Ice Cream Sandwich) doesn’t do anything. While testing on other devices exitValue in processComplete is always equal to 0, but on ICS it’s 11. Here is the output in LogCat :

  SHELL OUT: /data/data/org.hardartcore.ffmpeg/app_bin/ffmpeg -y -i /mnt/sdcard/Movies/NEXUS.mp4 -ab 160k -r ntsc-film -vf scale=568:320 -strict -2 /mnt/sdcard/Movies/Test.mp4
  
  PROCESS COMPLETE: 11

  I don’t think it’s something from ffmpeg, more like a problem when the library is trying to execute ffmpeg executable from raw folder in internal memory, but I can’t see any logs or errors which indicate that too.

  So my question is, if there is any mistake which I am doing using / running this code or something which can prevent ffmpeg executable from running on old devices with Android ICS ?

  Thanks in advance !
