    avdevice/decklink_dec : Convert decklink input module to use codecpar

    There are still a couple of deprecated calls that I’m not sure what to do with.
    
They are both related to some logic around AVCodecContext.coded_frame.
    
I couldn’t find anywhere that really documented what that was, or where it was intended to move to.
    
I left the warnings on.

  • ffmpeg : single frame from video is highly overexposed image

    9 avril 2021, par mcgregor94086

    I am using ffmpeg on a Raspberry Pi 400, attached to a camera array to capture one image from each camera.

    &#xA;

    Most images generated are highly overexposed and washed out. I am trying to understand which command line options I should set to prevent this over exposure.
    &#xA;Sample grossly over exposed image

    &#xA;

    Are there options I need to set for the camera to automatically set the right exposure, or some way to set the length of an exposure as opposed to just a "frame" ?

    &#xA;

    Also, each image is taking about 3 to 4 seconds to capture. I just want to capture the first possible frame and that's it. Is there a set of options which would capture the image is less time ?

    &#xA;
