    31 janvier 2010, par

    Le chemin d’un document audio ou vidéo dans SPIPMotion est divisé en trois étapes distinctes.
    Upload et récupération d’informations de la vidéo source
    Dans un premier temps, il est nécessaire de créer un article SPIP et de lui joindre le document vidéo "source".

  • Overlay a video on top of another video at a specific time offset and position using FFmpeg 6 [closed]

    15 janvier 2024, par user1768741

    I have 2 MP4 videos :

    


      

    1. background.mp4 - 720p, 10 seconds long

      2. 


    2. overlay.mp4 - 360p, 3 seconds long

      3. 


    


    I want to create a single video where at first background.mp4 is played, then overlay.mp4 is overlaid on the bottom right corner of background.mp4 (with some padding) starting at 00:00:04 (so both videos are playing simultaneously), then disappearing when it ends (at 00:00:07), while background.mp4 keeps on playing. I want to keep only the audio of background.mp4.

    


    I tried many FFmpeg commands to get this, but I get only partial results :

    


      

    1. Both videos are playing if I start the overlay at 00:00:00

      2. 


    2. Videos are playing but at a very low frame rate (seem to be laggy)

      3. 


    3. Overlay shows only the last frame

      4. 


    


    And more of unwanted results

    


    Also tried OpenCV using Python but to no avail

    


  • How can we play 2 videos side by side as per the resolution we provide to the output video and adjust the two input videos position

    1er décembre 2023, par Bhavya Nayak

    -> For playing two video side by side as per the output video resolution I provide :-

    


      

    1. I want output video of resolution 1280x720 so for this.

      2. 


    


    a. First I have trimmed the two video using below command :-

    


    ffmpeg -i input_viedo.mp4 -ss 00:00:10 -t 00:00:20 -vf      "scale=1920:1080,pad=1920:1080:0:0:yellow" -c:v libx264 -c:a aac -strict -2 output_video_trimmed.mp4



    


    b. Now to I want to play both the trimmed video into one output video file as per the position I provide , so for this I have tried below command which is not giving the correct output :

    


    ffmpeg -i output_video_trimmed_1.mp4 -i output_trimmed_2.mp4 -filter_complex "[0:v]scale=634:360[pad1];[1:v]scale=640:360[pad2];[pad1]pad=1280:360:0:100[tl];[pad2]pad=1280:360:634.752:130.392[br];[tl][br]vstack,scale=1280:720[output]" -map "[output]" -c:v libx264 -preset ultrafast -crf 18 -c:a aac -b:a 1280x720 output_final_video.mp4


    


      

    • In above command I have provide the specific width,height,top,left of the input video I want ,

      • 


    


    But it is not giving me correct output.

    


    —> Output I am getting by running this command is attached below :-

    


    Output video Image I am getting by running above command

    


    Actual output I want

    


    —> The issue in above command is while adding top it is not working properly , like top is not affecting the video so I want the solution for that.
