  • audio extracted from flv file via ffmpeg is of shorter duration than the actual flv video [closed]

    11 janvier 2013, par user1961143

    I have extracted audio from flv file via ffmpeg using this command :-

    ffmpeg -i 164_29.flv v19.mp3

    The flv videos duration is 3 minutes but the audio is of 2 mins 20 seconds only. On searching i found that the silent pieces of audio are removed when generating audio from ffmpeg. But i need the audio file to be of exactly same duration as flv video as later i need to put this audio in the flv video itself. Please help as this is urgent for our project. I am running the FFMpeg via .net windows service, so in case you know any other tool which can extract the audio of same duration as video and can be run via .net, it would be useful too.

    If you see the duration of video is of 3:04 but audio extracted from it is of 2:25 only.
    Actually i am using ffmpeg overlay to show two videos side by side in our debate project for the client. Now ffmpeg takes audio from first video by default. But we want the audio from both videos together as a debate going on. Hence I thought of a solution to extract audio from both videos and merge them and than apply them to the overlayed video. This will all work perfectly only if I get the complete audio from the video file i.e. of equal duration.
    For more information i am writing here the overlay command we are using :-

    **ffmpeg -i 164_29.flv  -vf "[in] scale=359:320, pad=2*iw+6:ih
     [left];    movie=164_30.flv, scale=359:320 [right]; [left][right]
     overlay=365:0  [out]" -b:v 3600k -y a1.flv**

    **This is the console output of this overlay command:-**

    C :\Users\ritika.thakur>ffmpeg -i 164_29.flv -vf "[in] scale=359:320, pad=2*iw+6
    :ih [left] ; movie=164_30.flv, scale=359:320 [right] ; [left][right] overlay=365:0
    [out]" -b:v 3600k -y a1.flv

    Everything is working fine except that we want audio from both videos playing together in final overlayed file. I would be highly grateful if you can help in this and let me know if its possible to do via ffmpeg or not.

  • File conversion to mp3 returning failure everytime using flutter package ffmpeg_kit_flutter

    6 novembre 2024, par Sanath balthar

    I am trying to convert a .wav audio file generated from a flutter's text to speech package - "flutter_tts" to mp3 file but it is failing everytime.
I have written the below code for file conversion. I have imported the package ffmpeg_kit_flutter. It doesnt even show why the conversion is failing.
I have looked up in stackoverflow and other sites but could not find any relevant solutions. I am using vscode as editor. I have attached flutter doctor output below as well. Could anyone please guide me ? Let me know if you need more information.

  • Change AVI creation date with ffmpeg ?

    1er novembre 2016, par brock

    As far as I can tell the following ffmpeg command should copy all existing metadata in the input file to the output file and modify the specified field in the output file :

    ffmpeg -i VID_20130502_220104.avi -metadata creation_time="2013-05-02 22:01:04" -codec copy VID_20130502_220104-2.avi

    Instead, it seems to strip all metadata from the output file. Here is the output of a few commands. I am going nuts. I think this should work, but why is it not ?

    Command to edit the creation time :

    ffmpeg -i VID_20130502_220104.avi -metadata creation_time="2013-05-02 22:01:04" -codec copy VID_20130502_220104-2.avi
