  • ffmpeg continuous live streaming of dynamic files from directory

    4 septembre 2022, par user72261

    So I have been using ffmpeg to create a live stream from files stored in a folder using concat list.

    


    This works perfectly for local, static content but I have a security system in my warehouse that uploads .mp4 files to my server in the office.

    


    This system doesn't have any live stream functionality so I would like to set up a live stream myself using ffmpeg to continually read the latest files from the folder.

    


    I tried setting up a script to read all files in the directory and sort them based on the file name that is a UNIX timestamp of the date/time the video was taken. Then had the script select the latest segments after that last used segment and create a new concat list such as below

    


    file '00000.mpd'
file '00001.mp4'
file '00002.mp4'
file '00003.mp4'
file '00004.mp4'


    


    After doing some reading I found out to make it loop that file you could reference its self in the list like so

    


    file '00000.mpd'
file '00001.mp4'
file '00002.mp4'
file '00003.mp4'
file '00004.mp4'
file 'concat.txt'


    


    This seemed to work ok until I started getting the error impossible to open concat.txt. This file doesn't exist, which I can only guess is because ffmpeg is trying to open the file as its being updated by the script.

    


    Has anyone come across this before or know another way to do it ?

    


  • Can ffmpeg copy parts from an rmvb file without re-encoding ?

    24 juin 2017, par Eng. M.Hamdy

    I want to fast copy parts from an rmvb file without re-encoding. This command works fine with mp4 files but not with rmbv (I dropped start time and duration here) :

    ffmpeg -i input -c copy output

    when I use it with rmvb like this :

    ffmpeg -i 1.rmvb -c copy 1.mp4

    I get this error :

    [mp4 @ 00bb8980] Could not find tag for codec rv40 in stream #0, codec
    not curre ntly supported in container Could not write header for
    output file #0 (incorrect codec parameters ?) : Invali d argument
    Stream mapping : Stream #0:1 -> #0:0 (copy) Stream #0:0 -> #0:1
    (copy)

    I also tried this :

    ffmpeg -i 1.rmvb -c copy 2.rmvb

    and got this error :

    [NULL @ 04748980] Unable to find a suitable output format for ’2.rmvb’
    2.rmvb : Invalid argument

    I tried this command :

    ffmpeg -i 1.rmvb -c:v copy -c:a aac -strict experimental -b:a 128k 1.mp4

    and got this error :

    [mp4 @ 046e0020] Could not find tag for codec rv40 in stream #0, codec
    not curre ntly supported in container Could not write header for
    output file #0 (incorrect codec parameters ?) : Invali d argument Error
    initializing output stream 0:1 — [aac @ 046e1bc0] Qavg : nan
    Conversion failed !

    I read this topic :
    but the solution does not work for me.. After many trials, this is the command that worked (and took too long time) :

    ffmpeg -i 1.rmvb -c:v libx264 -b:a 32k output.mp4

    But I do not want to re-encode the file. Any solution ?

    Edit :
    I tried :

    ffmpeg -i 1.rmvb -c copy 1.mkv
