Cross fading 2 videos segments using ffmpeg when number of frames are not known before hand
5 avril 2016, par Hero RomaI am a newbie trying to cross fade 2 videos using ffmpeg and the stackoverflow answer. But in my case I do not know the length of the video or the number of the frames. I want to start the fade out in the first video in the last 5 frames and fade in the first 5 frames. I am able to do the fade in on the second video but I cannot figure out how to do the fade out in the last 5 frames when I don’t know the duration or the number of frames.
The "-i" option is supposed to be able to extract that information but I cant seem to pipe it to the next block there.
ffmpeg -i 1.mp4 -i 2.mp4 -f lavfi -i color=black -filter_complex \
"[0:v]format=pix_fmts=yuva420p,fade=t=out:st=4:d=1:alpha=1,setpts=PTS-STARTPTS[va0];\
[1:v]format=pix_fmts=yuva420p,fade=t=in:st=0:d=1:alpha=1,setpts=PTS-STARTPTS+4/TB[va1];\
[2:v]scale=960x720,trim=duration=9[over];\

How to display name and phone number of a student as dynamic watermark (randomly floating on entire screen) in videos of a paid online video course ?
22 mai 2020, par ArjunI wish to make a Learning Management System using PHP-MySQL and wish to put videos from my computer or embed YouTube videos on it.



Videos will be displayed to only those students who have paid for the course.



I want to show their name and phone number (which they'll be giving during Sign Up) as a dynamic watermark floating randomly on all the videos of that course to prevent screen capturing of the video.



How to do it and how to call those Name and Phone Number values from the MySQL database ?
