Record specific window using ffmpeg
5 décembre 2022, par Ahmed A. MansourI have been trying the below code (which I found on other similiar problem on this site here : How to record a specific window using ffmpeg But it gives me black video and the same video is not playable by windows media player (it works on vlc but with black video..)


ffmpeg -f gdigrab -framerate 30 -i title="german.avi - VLC media player" -b:v 3M germ.flv



Video example :
Weird thumbnail by WMP which shows it can't play it
Black screen as described, but it opens with black video in VLC


I tried the other suggestions, but this one sometimes (less than 40% of the time) works.
I also noticed it doesn't show the window main title, which is a bit confusing, as it causes the mouse cursor to appear a little down where it should be.

How to add background image for text with text size on a video in FFmpeg ?
24 octobre 2019, par manwteinIs there way to add a background image under the text on the video in FFmpeg ?
I can add black background using ’box’, but i need to add some certain image. I tried to use ’drawtext’ on a image and then overlayed it on the video, but i don’t know text’s width and height for scaling the image.
"-i",
"D:/AndroidProjects/Movies/VideoSamples/VideoShort1.mp4",
"-i",
"D:/AndroidProjects/Movies/ImageSamples/SampleImage.jpeg",
"-filter_complex",
"[0:v]drawtext=text='Example':fontcolor=#DB7093:fontsize=120:box=1:boxcolor=black@0.8:boxborderw=5:x='(w/2) - (tw/2)':y='h - ((h/2) - (th/2))",
"-s",
"1280x720",
"-y",
"D:/AndroidProjects/Movies/FFmpegSampleShort0.mp4"I expect to get video with some image background under my text instead black color.

I want to make a box completely unrecognizable in a video without any way of reconstructing its content
26 janvier 2023, par Jenson vivishsaw many videos but couldn't find how to create


I want to make a box completely unrecognizable in a video without any way of reconstructing its content. Is


ffmpeg -y -i input_video -vf "drawbox=x=10:y=10:w=100:h=100:color=black@1.0:t=fill" ouput_video
sufficient for that ?


The command creates a black box at the desired location. I am just not sure if this cannot be undone.
