  • Video created via shell_exec() does not play, but video created via terminal does

    25 février 2021, par Mukul Kashyap

    I am creating a video from single audio and single image and it is fine when the audio length less than 10 seconds but when the audio length exceeds 10 seconds then video not playing. I am using FFmpeg to create video using shell_exec().
The video is fine when I directly runs the FFmpeg command on the terminal but the only issue comes with the shell_exec command.

    


    This command I am using -

    


    ffmpeg -loop 1 -f image2 -i $this->img_url -i  $this->audio_url -vf scale=1920*1080 -pix_fmt yuv420p -vcodec libx264 -shortest ".$video_local_dir.$video_name;

  • ffmpeg terminal : How can I re-encode a video file using all the parameters copied from another video ? [closed]

    5 décembre 2022, par Lever

    I have two videos A and B. How can I re-encode B using ALL the parameters of A ?
I would like to use both A and B as inputs, but all parameters are extracted from A, then B is re-encoded with the A-parameters including both video and audio. Is there a simple command to copy ALL the parameters of A ?

    


    Thanks !

    


    I know the typical parameters of a video includes the resolution, fps and so on. But it seems that I always miss something rather than get ALL the parameters to make A and B the same.

    


    The background is that I need to concatenate about 100 videos, but only a few of which has lower quality than others. I don't want to re-encode all of them. Therefore I'm trying to re-encode the lower ones to match the others, and then I can use the file-level concatenation command avoiding re-encode all of them.
