  • FFMPEG - how to fill-in an image when input stream or device are down ?

    19 novembre 2022, par Henry Aloni

    I want to output a stream from FFPEG so that if the feed is down, the stream is populated with a "we are experiencing difficulties" image.

    


    Can I do that using only FFMPEG ?

    dashenc : Reduce the segment duration if cutting out parts with edit lists

    This makes sure that the time + duration of the first segment
    
matches the start time of the next segment for e.g. AAC audio
    
with encoder delay.

  • Segmenting video into different parts and unique rendering on each part then concat afterwards

    2 mars 2016, par goudarziha

    I currently have a very poorly performing application that splits up a video, renders it and the concats all rendered videos on android using ffmpeg

    So I am running into issues with segmenting a video up into 5 parts at each different intervals/durations, rendering each video segment uniquely slowing up/speeding up and then finally concat all the segments back into one final video.

    Currently I am doing each part separately -

    Segmenting -
    example for one segment
    -y -i pathIn -ss 0.0 -t 2.0 -vcodec copy -acodec copy -an pathOut

    Rendering - example slowing down/speeding up

    - y -i path -filter:v setpts=2.0*PTS pathOut

    Concat -

    - f concat -i input1.mp4 -i input2.mp4 -i input3.mp4 -i input4.mp4 -i input5.mp4 -c copy output.mp4

    Right now I am running different separate thread for each editing of video, so 3, segment, rendering and concat.

    I am trying to get this all done on one command ffmpeg line if at all possible, if not just the segmenting and rendering of the videos and kick of the concat cmd line later.

    I am trying to emulate something similar to this https://trac.ffmpeg.org/wiki/Creating%20multiple%20outputs
