  • Making screenshots in FFmpeg : How to deal with differing actual width vs displayed width ? [duplicate]

    15 mars 2020, par browncatmegazord

    I usually have no problem making gifs and screenshots from a video with FFmpeg using standard commands like so :

    ffmpeg -i input -frames:v 1 -q:v 2 output.jpeg

    Recently I had to deal with an .mkv file that had a pixel width of 720, but a "display width" of 853 (Apparently this non-square pixel stuff is a thing), and my usual commands would give me a 720x480 screenshot that is oddly squashed.

    I managed to force its size by adding a -s 853x480 into the above command, but it looks a little bit stretched, and I suspect there’s a cleaner way to do this without me having to manually check what the displayed width is.

    Would appreciate some insight about this !

  • FFMPEG overlay not shown in certain players [closed]

    4 février 2024, par Hamed

    I'm trying to add an overlay to my video using ffmpeg. Here is my command :

    


    ffmpeg -y -i {input_video} -i {overlay_video} -filter_complex "[1:v]trim=start_frame=1991:end_frame=2027,scale=300:1,setpts=PTS-STARTPTS[clip2];[0:v][clip2]overlay=25:25" -map 0:v -map 0:a? -c:v libx264 -crf 20  {output_video}


    


    Now the overlay is added alright, but some video players don't show the overlay video. It's almost as if it's not supported. When I convert the video once more (using any tool, doesn't matter) the overlay is added permanently. How does the process work here ? how can I so called "bake" the overlay onto my input ?
