  • Rotate video, output maximum 1920 x 1080 pixels

    9 avril 2014, par Fabien Biller

    I used

    ffmpeg.exe -ss 310 -i "H:\_REC\100MEDIA\someavi.AVI" -ss 0 -t 14 -vf "rotate='54*PI/180:ow=hypot(iw,ih):oh=ow'" -vf scale=1920:1080 "H:\_REC\100MEDIA\somemp4.mp4"

    which should rotate the video(currently 1920 x 1080, MJPEG, 30fps) around 54° and fit it into 1920 x 1080 Pixels.

    What it does is, it ignores the -vf "rotate='54*PI/180:ow=hypot(iw,ih):oh=ow'" -vf scale=1920:1080 and returns the snippet.

    What to change ?

    PS : ffmpeg version N-59696-gc0a33c4

    16 mars 2018, par yue guan

    FFmpeg scale 720*1080 video to 720*404, it not effect, it plays as 279 × 404, and use cmd ffmpeg -i scaled.mp4 it shows 720*404.
    Then I use cmd ffmpeg -i scaled.mp4 -y -f image2 -ss 1 -vframes 1 ./xx.jpg to get the thumbnail, but I got the size is 720*404.
    Why ?
    and How can I capture the thumbnail of the video as 279*404 ?
    and How can I scale the video as the size what I defined ?

    5 mars 2020, par Ahmed Kaicer

    How to auto delete files every 3 hours in a directory var/www/html/stream that file name start with 1080 or 720 or 480 or 360 ?

    Iam doing this because once ffmpeg stops for any reason, it still keeps the old file and folder size is huge. Thanks for your help
