How to put watermak on video with FFMPEG,without resizing the watermark becuase of video resolution ?
27 septembre 2013, par Shahbaz YounisIm looking for a way that the watermark picutre does not get resized,if the video resolution is high or less.Right now i have this problem,if i upload a video like 720p the watermak is really small and when i upload a video that is 240p the watermak is really big.I would just like it to be only one size.Can it do that automatically ? So no matter what the resolution is the of the video the image does not resizes and stays where i put it ? here's the code im using right now
if ($ffmpeg_ver == "old") {
$watermark = '-vf "movie='.$tv_logo_path.' [watermark]; [in][watermark] overlay=10:10 [out]" ';
} else {
$watermark = '-i '.$tv_logo_path.' -filter_complex "overlay=10:10" ';

ffmpeg : jpeg-images with different resolution -> video sequence ; using padding instead of scaling [on hold]
3 septembre 2013, par user2742503I am currently struggling with the following problem using ffmpeg : I have a bunch of jpg-files with different resolution (say, one is 320x240, one is 800x600 etc) and want to create an avi-file using mjpeg as a video codec withn a output-video resolution of 800x600. The images itself should not be scaled in any way, that means : What I want to achieve is to just place the image in the center and fill the remaining space with white or black instead of scaling up the smaller images to the target resolution.
So far I have used
ffmpeg -f image2 -r 1 -i image_%04d.jpg -vcodec mjpeg -s 1920x1080 -qscale 2 -r 25 output2.avi
or
ffmpeg -f image2 -r 1 -i image_%04d.jpg -vcodec mjpeg -vf scale=1920:1080 -qscale 2 -r 25 output2.avi
in case of scaling to HD resolution.
Would be very thankful for any support on that !
Thank you in advance !
