  • ffmpeg - compositing a video within a video in the centre

    1er mars 2017, par kieran

    I’m looking to composite a video with ffmpeg that places the video in the centre no matter what the composited video’s aspect ratio/size.

    The "background" video will always be 16:9 and 1920x1080px. I won’t know the aspect ratio or size of the overlay video as it will be user uploaded and could be any size/ratio.

    Here’s an example of what I’m trying to achieve :

    This is the background image :

    enter image description here

    Now I want to overlay a video over the top :

    enter image description here

    This should also work :enter image description here

    Essentially no matter what the dimensions I want to ensure it’s always resized to fit within 1920x1080 and in addition ensure it’s always centred.

    Finally, if the uploaded video is also 16:9 it should simply overlay the entire video :

  • How to speed up video and its timestamp to shorten video length, but represent time as it was recorded ?

    7 janvier 2021, par Gonzalo Aspee

    I have a video recorded at 5 fps that I want to speed up to 30 fps to shorten it. That is simple enough as :

    


    ffmpeg -i input.mp4 -r 30 -vf "setpts=0.16666*PTS" output.mp4


    


    But when I try to add a timestamp to it with :

    


    ffmpeg -i input.mp4 -r 30 -vf "setpts=0.16666*PTS, drawtext=text='%{pts\:localtime\:1610043985\:%Y\-%m\-%d %H\\\\\:%M\\\\\:%S.}%{eif\:mod(n,30)\:d}'" output.mp4


    


    The timestamp does not longer represents the time as it was recorded (it should run faster now)

    


    How to achieve this ?

    


  • How to create m3u8 playlist from mp4 video url ( stored in amazon S3 ) and store the video chunks ( .ts files) and .m3u8 file back to another S3 ?

    19 mai 2019, par dexter2019

    I am building an application where user can upload video and others can watch them later. I am aiming for HLS streaming of the video on the client side, for which the video format should be .m3u8. I am using node fluent-FFmpeg module to do the processing, however, I have a huge doubt, that, how to ensure that all the .ts files (chunks) are also stored back in s3 bucket along with the m3u8 file after ffmpeg processed the mp4 file ?

    Because the ffmpeg command only takes the location of the m3u8 file ? How handle it when I want the input and output location to be S3 ?

    Any help will be greatly appreciated.

    I am following the answer from this question Ffmpeg creating m3u8 from mp4, video file size , which is working absolutely fine in my local machine, how to achieve the same for s3 ?
