  • FFPLAY shows video, but FFMPEG just shows black

    22 mai 2017, par ahenshaw

    I’m trying to record video/audio from a VIDBOX device using ffmpeg. Using Windows 10 and ffmpeg version N-86129-g1e8daf3, I can see and hear the video/audio fine when I execute

    ffplay -f dshow -i video="VIDBOX NW07":audio="Microphone (VIDBOX NW07)"

    but, I only record a black screen (and the correct audio) when I execute

    ffmpeg -f dshow -i video="VIDBOX NW07":audio="Microphone (VIDBOX NW07)" -c:v libx264 out.mp4

    What could be causing this to work in ffplay but not ffmpeg ?

  • FFMPEG - crop and pad a video (keep 3840x1920 but with black borders)

    23 avril 2020, par SteenPetersen

    I am trying to crop a video so that I can remove a chunk of the content from the sides of a 360-degree video file using FFmpeg.

    &#xA;&#xA;

    I used the following command and it does part of the job :

    &#xA;&#xA;

    ffmpeg -i testVideo.mp4 -vf crop=3072:1920:384:0,pad=3840:1920:384:0 output.mp4&#xA;

    &#xA;&#xA;

    This will remove the sides of the video and that was initially exactly what I wanted (A). Now I'm wondering if it is possible to crop in the same way but to keep the top third of video. As such, A is what I have, B is what I want. :

    &#xA;&#xA;

    enter image description here

    &#xA;&#xA;

    I thought I could simply do this :

    &#xA;&#xA;

    ffmpeg -i testVideo.mp4 -vf crop=3072:1920:384:640,pad=3840:1920:384:640 output.mp4&#xA;

    &#xA;&#xA;

    But that doesn't seem to work.

    &#xA;&#xA;

    Any input would be very helpful.
