    vqavideodev : Check image dimensions

  • Use ffmpeg to watermark and scale an image on video

    11 mai 2015, par Ae.

    I want to be able to watermark videos with a logo image, which contains a website url.
    The videos can be of different formats and dimension.
    I’m trying to figure out a generic ffmpeg command to achieve it, so that i don’t have to tweak the command depending on the video i have to process.
    So far i got :

    ffmpeg -i sample.mov -sameq -acodec copy -vf 'movie=logo.png [watermark]; [in][watermark] overlay=main_w-overlay_w-10:main_h-overlay_h-10 [out]' sample2.mov

    In this way though the logo will look too big or too small with video of different size.
    I’ve seen there is a scale option for avfilter, but I haven’t figure out whether it’s possible to resize the image logo based on the dimension of the input video, so that I can say to scale the logo to 1/3 of the video length for example, and keep the image ratio.

    Any idea ? doesn’t need to be done in a single command, could even be a script.
    thanks in advance.

  • Does ffmpeg play the entire video file to extract image

    21 mars 2012, par user735647

    I have a multimedia application which involves lot of videos. I use FFMPEG to generate the thumbnails from the video at a particular time duration. Now the problem is my console application which is used to extract the images from the video is consuming lot of memory when its being run.

    The doubt I have now is whether FFMPEG does play the entire video file when extracting the thumbnail image.Is it possible ?

    Following is the parameter being passed to FFMPEG,

      -i [input video file] -an -r 0.05 -y -ss 00:00:18 -vframes 1 [output thumbnail file path]

    I tried googling but with no success. Please provide your valuable thoughts.

    Thanks.
