  • ffmpeg modify audio length/size ( stretch or shrink)

    14 juin 2016, par mido

    I am developing a web app, where people can record videos. I have been able to send chunks of audio n video to server successfully, where I am trying to combine them and return as single proper file.

    my problem is if the recording is for one hour, after merging the chunks

    video length : 1:00:00 , audio length : 00:59:30,

    now, this is not a issue of audio not getting recorded( I have checked that), the problem is, somehow, when i merge the chunks of audio, it shrinks,

    I find that it is progressive sync issue where it gets worse and worse as time increases.

    I have searched the net for the solution, most places say async, I have tried using it, but to no avail, is the below usage correct ?

    ffmpeg  -i audio.wav -async 1 -i video.webm -y -strict -2 v.mp4

    (v.mp4 is the final file that I provide to the users.)

  • How to wait for file close in Linux

    27 septembre 2014, par user180586

    My security cameras recorders (located in distant places), FTP`s to my server video files after any event. Using find and ffmpeg commands, server converts DAV file to AVI and remove DAV file using syntax like this :

    find $katalog -type f -name "*.dav" -exec ffmpeg -y -i {} -vcodec libx264 -crf 24 {}.avi >/dev/null 2>&amp;1 \; -exec rm -f {} \;

    I use "inotify" to trigger conversion action.
    The problem is when two or more recorders ftp`s files to server. "inotify" trigger conversion action when first file will be transmitted completely. But other recorders will be still transmit files, so such files will not be closed.
    How can I modify above syntax to be sure that ffmpeg conversion will be done only on closed (fully transited) files ?
