What are the required domains to know to make a video editor application for android ? with features like Speed, Rotation, Transition, Trim, Split
19 avril 2020, par MahfuzI wanted to make a Video Editor application for Android. But I am not sure whether only FFMPEG is enough or not. In this application I want to add features like Trim, Split, Filter, Speed, Rotation, Transition, Text, Music etc. I think only FFMPEG is not enough, some other Library or Domain I have to know. Can any one help on this ?

ffmpeg : How to speed up (and keep only) a specified portion of an input video
17 avril 2020, par shrimpwidgetIn my input video is a 48 second range that I wish to speed up. I wish to save only that sped up portion to a new video.



Solution :



ffmpeg -y -ss 00:00:03 -t 00:00:48 -i input.mp4 -an -crf 20 -pix_fmt yuv420p -vf "scale=1080:-1, setpts=PTS/10.0" "output.mp4"

Is there a way to non-linear speed-up video with ffmpeg ?
3 mars 2020, par leoossaI’ve seen thousands of websites suggesting using setpts to speedup video
ffmpeg -i input.mp4 -filter:v "setpts=0.5*PTS" output.mp4
The thing is - I don’t want to speed-up video in a linear way. I want it to accelerate. So I want ’acceleration’ (Wiki) to be constant and ’speed’ to be growing.
From what I’ve seen on ffmpeg docs setpts can be an equation, I tried to play with PREV_OUTPTS but with no success.
Is it even possible to achieve that with ffmpeg ?
