  • Time lapse video using ffmpeg

    18 octobre 2017, par Rich S

    I’m trying to create a time-lapse video from 376 separate images. I want to adjust the framerate to get the best/smoothest result, but my video only includes 343 of the frames in the file.

    I’m using a text file (sequence.txt) to list the files..

    file 'images\20171016T040000Z.jpg'
    
duration 0.1
    
file 'images\20171016T040140Z.jpg'
    
duration 0.1
    
file 'images\20171016T040320Z.jpg'
    
duration 0.1
    
etc...

    And then running

    ffmpeg -safe 0 -f concat -i sequence.txt -pix_fmt yuv420p -y out.mp4

    As far as I can tell, the actual frame-rate of the output file will be 25fps (the default), and the duration of each frame will be 1/10 second. So there will be a few input frames duplicated for each output frame. But this shouldn’t be a problem.

    Why would the video only show the first 343 frames - actually I’ve just noticed that it’s exactly 90% of the required length.

    EDIT

    The log from running the ffmpeg is below

  • ffmpeg output separate channel from an input with multiple channels

    11 octobre 2017, par tiras muturi

    i run this command to be able to stream a udp live stream to a http live stream that is playable using a mobile application that am building.
    its just a stream with audio streams only.

    i really want a way i can be able to map every input stream to have an output stream that can be accessed separately from the other like maybe if i need the first stream maybe i will just

    ffplay http://localhost:8090/feed1.ffm

    and if i need the 7th stream i will just

    ffplay http://localhost:8090/feed7.ffm

    Please can someone help me crack this issue. FFmpeg dont have complex examples for my current situation.

    this is my header information

  • ffmpeg : single input file contains multiple streams, how to save each discreetly ?

    9 octobre 2017, par pinhead

    I have been given a .dvs file which was recovered from some proprietary multi-camera security surveillance system. ffprobe returned errors at first but when I switched the extension to .avc I was able to extract video metadata (output below). ffmpeg was able to read this file and export a long video file that essentially jump-cuts between the different cameras in an erratic pattern, like a crazy music video ! Is it possible to use ffmpeg to identify the different parallel video streams and output each camera source as its own file ?

    ffprobe -probesize 1000000000 output :
