  • Creating video out of many video clips

    25 janvier 2017, par user2821420

    I have a series of video clips which need to go at certain times after the beginning of a video. For example, I may have test1.mp4 at 833 milliseconds after a video starts and then test2.mp4 might play 7460 ms after the video starts. The video should show black until 833 ms then after that video ends, test2 should play at 7460 ms. I don’t see an easy way to do this just using ffmpeg, what should I use to do this ?

  • Flutter get video frames using video player or ffmpeg

    7 mars 2021, par lulliezy

    I have a flutter app that processes videos, now, I want to display like a video timeline at the bottom of the video but it should be comprised of the video frames of the video at various points, my googling has been fruitless so far and I was hoping to achieve this using flutter video_player and/or flutter_ffmpeg (I use these packages in my app). I have tried to look this online but I want to avoid using another package just for this, how do i achieve this using either or both the packages ?

    


    Thanks in advance

    


  • Ffmpeg video freeze for longer video

    10 mars 2016, par Vishnu

    I have a video of 30 seconds , I am making it 1 hour video using below code

    echo shell_exec('/usr/local/bin/ffmpeg -y -i universal.mp4  -f lavfi -i "color=black:s=1280x720:r=24:d=3600" -filter_complex "[0][1]concat=n=2:v=1:a=0[v]" -map [v] -c:v libx264 -map 0:1 -c:a libfdk_aac -b:a 256k output.mp4  2>&1');

    So The output.mp4 created using above code is 1 hour long and it is getting freezed by vlc ,windows mediaplayer when I seek to certain minutes.But when I set duration d=300 , output video is perfect. Why does long video gets freezed from above output.
