• Cannot include ffmpeg.exe using auto-py-to-exe

  4 avril 2024, par YYY

  I'm trying to generate an exe for my PyQT application that uses ffmpeg using auto-py-to-exe.

  


  Within the application, there are calls to ffmpeg as an os command (like 'ffmpeg -i file ... output) .
As I have ffmpeg installed on my machine and accessible from the Windows Path, when I run the app exe on my machine, I don't have any issue.

  


  However, when it's someone that doesn't have ffmpeg installed, he/she encounters an error like "'ffmpeg' is not recognized as an internal or external command, operal program or batch file"

  


  I don't want to put ffmpeg within a folder of the app as I call local modules that already call ffmpeg as an os command.

  


  I have tried first to add ffmpeg.exe as a file (as recommended in one stackoverflow post) and then as a binary but without success


  


  I've already tried with the configuration stated in this

  


  Can anyone help me on this ?

  


  EDIT N°2

  


  It turns out that when I export the exe on my machine by including ffmpeg as a binary either with pyinstaller or auto-py-to-exe, the final exe doesn't recognize the ffmpeg command even if it's in the folder.

  


  

  


  However, I've tried the same configuration on another machine and it worked without any error.

  


  I've tried to install another ffmpeg version and link this version on the final exe but without success

  


• ffmpeg concat : 2nd video stream frozen, no image

  31 juillet 2016, par Azevedo

  I’m trying to concatenate two video streams with the same econding into one :

  ffmpeg -y -f concat -i parts.txt -c copy join.mkv

  parts.txt

  file part1.mkv
  
  file part2.mkv

  ffmpeg will concatenate them but the playback (any player) gives a still image if the playing position corresponds to the 2nd part.
  I tried to switch part1.mkv and part2.mkv to see the results.
  The 1st part (whichever part1 or part2) will play normally but when I seek the playback to the time corresponding the 2nd part the image won’t show, only the audio plays.

  
  
  What happens if i seek the playback to the 2nd part :

• Using JavaCV/FFMPEG to push byte buffer image via RTMP

  6 mai 2022, par ljnoah

  I have a USB camera that returns frames as a byte buffer type to which I would like to push/send via rtmp using JavaCV library to be viewed using VLC. According to this link : http://bytedeco.org/javacpp-presets/ffmpeg/apidocs/org/bytedeco/ffmpeg/ffmpeg.html. It should be possible, but I don't really have any experience with ffmpeg, but from what I've read in their github it should be possible, only, thus far I was not able to find an example on how to do it. Basically, I would like to store a byte buffer and send an image that is in variable instead of grabbing frames from a camera as my USB camera is not detected by android and needs external libraries to work.

  


  private byte[] FrameData = new byte[384 * 288 * 4];
  //private final Bitmap bitmap = Bitmap.createBitmap(PREVIEW_WIDTH, PREVIEW_HEIGHT, // Bitmap.Config.ARGB_8888); // creates a bitmap with the proper format in-case its needed
  private final IFrameCallback mIFrameCallback = new IFrameCallback() {
      @Override
      public void onFrame(final ByteBuffer frameData) {
          frameData.clear();
          frameData.get(FrameData, 0, frameData.capacity());
          }
  };


  


  This callback gives me the frames from my camera on the fly and writes it to FrameData, which I can compress to a bitmap if needed.

  


  My camera preview where I call the callback above :

  


    public void handleStartPreview(Object surface) {
      if ((mUVCCamera == null)) return;
      try {
          mUVCCamera.setPreviewSize(mWidth, mHeight, 1, 26, UVCCamera.DEFAULT_PREVIEW_MODE, UVCCamera.DEFAULT_BANDWIDTH, 0);
      } catch (IllegalArgumentException e) {
          try {
              mUVCCamera.setPreviewSize(mWidth, mHeight, 1, 26, UVCCamera.DEFAULT_PREVIEW_MODE, UVCCamera.DEFAULT_BANDWIDTH, 0);
              Log.e(TAG, "handleStartPreview4");
          } catch (IllegalArgumentException e1) {
              callOnError(e1);
              return;
          }
      }
      int result = mUVCCamera.startPreview();
      mUVCCamera.setFrameCallback(mIFrameCallback, UVCCamera.PIXEL_FORMAT_RGBX);
      mUVCCamera.startCapture();
      startRecording();
  }


  


  My question is How can I use this example :

  


   String ffmpeg = Loader.load(org.bytedeco.ffmpeg.ffmpeg.class);
 ProcessBuilder pb = new ProcessBuilder(ffmpeg, "-i", "/path/to/input.mp4", "-vcodec", "h264", "/path/to/output.mp4");
 pb.inheritIO().start().waitFor();


  


  to push my frames from the camera that are stored FrameData byte buffer via RTMP/RTSP to my server IP, even If I need to compress it to a bitmap before...
