  • ffmpeg : How to speed up (and keep only) a specified portion of an input video

    17 avril 2020, par shrimpwidget

    In 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"


    


  • 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 Mahfuz

    I 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 stuck at 00:00:00 speed=0x for a long time at the beginning

    4 juin 2020, par lagmoellertim

    I'm currently writing a script that can remove silence from any video. I'm doing this using ffmpeg and a complex_filter script.

    



    Since most of my videos are pretty long (>1.5h), ffmpeg is called multiple times with a different complex_filter, each editing a part of the video (about 8 minutes long each) and combining those parts at the end.

    



    The input file for all these separate parts is always the original 1.5h video clip.

    



    The problem I keep getting is that for videos starting not directly at the start (first part works fine, second part starting at minute 8 takes longer, third part starting at minute 16 even longer, ... you get the point), this shows up and gets displayed for quite a long time, until it finally works with its normal speed :

    



    frame=    0 fps=0.0 q=0.0 size=       0kB time=00:00:00.00 bitrate=N/A speed=   0x

    



    Here is the ffmpeg script I use

    



    ffmpeg -i video.mp4 -vsync 1 -async 1 -safe 0 -filter_complex_script /path/to/complex_filter -y -map '[vout]' -map '[aout]' video_parts/infb4_3.mp4

    



    I also tried adding -ss 00:24:00 before or behind the -i input, but I did not notice any speed improvement.

    



    And here the complex_filter of one part of the video, starting at minute 24 and ending at minute 32 :
