  • ffmpeg to convert mov to flv

    27 octobre 2014, par jeet

    I’m trying to convert a mov video to flv, but keep getting these errors below.
    There are 2 commands I used, both are below.

    ffmpeg -y -i video.mov -deinterlace -acodec copy -r 25 -qmin 3 -qmax 6 video.flv

    1 more thing please :
    If I use this newer version of ffmpeg to create a video with the below command, I get a video with a very hazy display.
    It’s like a few black dots on a blank screen :

    ffmpeg -i img%d.png -i audio.wav -acodec copy output.mov

    what could be the reason for this display ?

  • slowing down a video with ffmpeg

    20 août 2014, par jeet

    I’m making a video using ffmpeg & multiple images with this command :

    ffmpeg -f image2 -i img%d.png v.mpg

    The video is made, but plays very fast. Can I slow it down a bit ? (double duration nearly)
    If possible set the speed while creation itself please.

    I also need to add an audio "a.wav" to the video being made, possibly in the same command. Is that possible ?

    Please give me the commands
    Thanks

    When I use this command, below is the error I get :

    ffmpeg -r 12 -i pic\s%d.png -i rmt.wav -shortest -r 25 v.mpg

  • Video length missing in FLV converted by ffmpeg-php

    19 janvier 2013, par Andrew

    I'm converting MP4 videos to FLV using ffmpeg-php on my CentOS server (without intervention from flvtool2 because it's not installed).

    The FLV videos are created, but no player is capable of retrieving the video duration, this creates serious issues when trying to seek the video. I'm using the player created by Moyea's Flash Video MX Pro, but the problem also happens with other FLV players as well, so I'm sure that ffmpeg-php is not createing the FLV with the proper length data.

    My MP4 videos are compatible because ffmpeg-php CAN get the video length properly from then, yet it does not apply that length information into the FLV file. I assume flvtool2 is ONLY to retrieve meta-data and has nothing to do with the output FLV video length, let me know if this is correct.

    This command I use for conversion :

    $command = "ffmpeg -i myvideo.mp4 -ar 22050 -ab 64k -f flv -s 320x240 -y myvideo.flv";
    $result = @shell_exec($command);

    This is my ffmpeg-php version :

    Any help on this issue will be greatly appreciated.
