  • End the video when the overlay video is finished [closed]

    7 janvier 2024, par Christian Safka

    I have an overlayed video which can be longer or shorter than the background video.

    


    Case 1 : If the background video is longer, the video should end when the overlayed video is over.

    


    Case 2 : If the background video is shorter, it should repeat the last frame of the video until the overlayed video is over.

    


    With the shortest=1 and eof_action commands I haven't been able to achieve this without compromising one of the above cases. For example with shortest=1 in the overlay command, case #1 works but in case #2, both videos freeze when the background video ends while the audio plays out.

    


    Note that only the overlayed video has audio. Thanks !

    


  • Create a Video file with Accord.video.ffmpeg and vb.net [on hold]

    11 août 2017, par ATsiri

    I am new in VB.NET Programming. I am trying to make an application that grabs my USB camera and then I can make a video file from it.

    I have searched a lot and found out that Accord.video.ffmpeg can do this job.

    I have managed to capture my USB camera but I am having a problem to make a video file and save it to my debug folder.

    Any ideas ? How can I do it ?

  • Overlay a video with rounded corners - FFMPEG React Native (Like Facetime or other Video Chats)

    25 février 2024, par Christopher Gabba

    I'm trying to overlay one video on top of another using FFMPEG, in the exact same format as FaceTime, but the video would have rounded corners. I've tried the commands on other posts but they all generate unexpected results or errors.

    


    Here is the command that overlays the videos decently :

    


    -i main_video.mp4 -i small_overlaid_video_in_lower_left_corner.mp4 -filter_complex \
        "[0:v]scale=iw:ih[main_scaled]; \
        [1:v]scale=iw/2:ih/2:force_original_aspect_ratio=decrease,format=yuva420p[reaction_resized]; \
        [main_scaled][reaction_resized]overlay=x=40:y=H-h-40:format=auto[final]" \
        -map "[final]" -map 1:a? -c:a copy -c:v libx264 -crf 18 -preset ultrafast -t -y output.mp4


    


    The problems this has is that the main videos resolution varies from video to video, so sometimes the overlaid video is super small and sometimes its too big. Three questions :

    


      

    1. How do I make the overlaid video the same size in comparison to the main video every time ?

      2. 


    2. How can I apply rounded corners on the rectangle ?

      3. 


    3. How can I modify it to include both video's audio ?

      4.
