• Invalid argument error in writing video file using moviepy and ffmpeg

  28 janvier 2024, par Kresreb

  I have this code that used to work fine and now isn't. I have this error :

  


      Traceback (most recent call last):&#xA;  File "D:\videos\tiktoks\faitsasavoir\bot\mre.py", line 18, in <module>&#xA;    clip_final.write_videofile(f"rendus_finaux/output.mp4", fps=24)&#xA;  File "", line 2, in write_videofile&#xA;  File "C:\Users\Brice\AppData\Local\Programs\Python\Python39\lib\site-packages\moviepy\decorators.py", line 54, in requires_duration&#xA;    return f(clip, *a, **k)&#xA;  File "", line 2, in write_videofile&#xA;  File "C:\Users\Brice\AppData\Local\Programs\Python\Python39\lib\site-packages\moviepy\decorators.py", line 135, in use_clip_fps_by_default&#xA;    return f(clip, *new_a, **new_kw)&#xA;  File "", line 2, in write_videofile&#xA;  File "C:\Users\Brice\AppData\Local\Programs\Python\Python39\lib\site-packages\moviepy\decorators.py", line 22, in convert_masks_to_RGB&#xA;    return f(clip, *a, **k)&#xA;  File "C:\Users\Brice\AppData\Local\Programs\Python\Python39\lib\site-packages\moviepy\video\VideoClip.py", line 300, in write_videofile&#xA;    ffmpeg_write_video(self, filename, fps, codec,&#xA;  File "C:\Users\Brice\AppData\Local\Programs\Python\Python39\lib\site-packages\moviepy\video\io\ffmpeg_writer.py", line 228, in ffmpeg_write_video&#xA;    writer.write_frame(frame)&#xA;  File "C:\Users\Brice\AppData\Local\Programs\Python\Python39\lib\site-packages\moviepy\video\io\ffmpeg_writer.py", line 180, in write_frame&#xA;    raise IOError(error)&#xA;OSError: [Errno 22] Invalid argument&#xA;&#xA;MoviePy error: FFMPEG encountered the following error while writing file rendus_finaux/output.mp4:&#xA;&#xA; b&#x27;rendus_finaux/output.mp4: No such file or directory\r\n&#x27;&#xA;</module>

  


  It tried different versions of moviepy, Python and reinstalling ffmpeg etc, but couldn't solve it. My main idea is that is a version problem, but i can't find out.

  


  I recreated the error with this mre, it's just a code to make a video from multiple images. Thank you for your help.

  


  from moviepy.editor import ImageClip, CompositeVideoClip, concatenate_videoclips
    
    DURATION_PER_IMAGE = 5
    
    images = ["D:/videos/image1.png","D:/videos/image1.jpg"]
    
    clips = []
    for image in images:
        #Main image
        clip = ImageClip(image).set_duration(DURATION_PER_IMAGE).resize(width=1080)
        clip = clip.resize(lambda t : 1+0.02*t)
    
        #Create clip composite
        clip_composite = CompositeVideoClip([clip.set_position("center")], size=(1080,1920))
        clips.append(clip_composite) # Add created clip to the list of clips
    
    clip_final = concatenate_videoclips(clips)
    clip_final.write_videofile(f"rendus_finaux/output.mp4", fps=24)


  


• How to convert video file to audio file by using FFMPEG ?

  15 janvier 2020, par Aamir Naseer

  I’m making video to audio converter app but need help to convert video to audio using ffmpeg. I checked many answers and websites but their answers are not easy to understand and I’m confused with command that is used to convert. What is the proper command to convert video to audio and is I’m executing the command in right way ?

  public class VideoConvertActivity extends AppCompatActivity {
  
  
  
      private VideoView videoView;
  
      private Button convertButton;
  
      private String filePath;
  
      private FFmpeg ffmpeg;
  
  
  
  
  
      @Override
  
      protected void onCreate(Bundle savedInstanceState) {
  
          super.onCreate(savedInstanceState);
  
          setContentView(R.layout.activity_video_convert);
  
  
  
          videoView = findViewById(R.id.videoviewID);
  
          convertButton = findViewById(R.id.convertbuttonID);
  
  
  
          ffmpeg = FFmpeg.getInstance(VideoConvertActivity.this);
  
  
  
  // in variable video i'm getting the path of video path from previous activity through intent and that video will have to convert to audio file
  
          Intent extras = getIntent();
  
          final String video = extras.getStringExtra("video");
  
  
  
          videoView.setVideoPath(video);
  
          videoView.start();
  
  
  
          convertButton.setOnClickListener(new View.OnClickListener() {
  
              @Override
  
              public void onClick(View v) {
  
  
  
                  try {

• How can i combine a 1 video file (flv) with image file using ffmpeg ?

  6 mars 2016, par user6964

  I have the following question. I need to combine 1 video (.Flv) to an image (png or jpg) generating a new video (.Flv) and then combine it with another video (.Flv). The flow should be as follows :

  First, combine a video image where the video should play normally until the last second and then the image should appear.

  Second, combining the resulting video with another video.

  I tried to do the first step with the following command :

  ffmpeg-i-loop_input movie_1.flv picture.png-i-acodec copy-shortest movie_output.flv

  But the result is that the image is displayed over video.

  Then try connecting 2 flv videos with the following command :

  ffmpeg-i-i movie_2.flv output_final.flv movie_output.flv

  But only shows 1 video in "output_final.flv".

  Can you tell me I’m doing wrong in my command ?

  Thank you.
