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

  6 March 2016, by 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.

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

  15 January 2020, by 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) {

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

  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)
