    Why it is giving unrecognized option 'vf' while it works fine when run directly on server.My command is : "ffmpeg -i /usr/slideshow/frame1.mp4 -vf 'fade=out:0:5' /usr/slideshow/fade1.mp4"

    I am executing it with exec() function. Why the error is coming and what should i use to apply filter to my input video. I am working on CentOS server.

    Please guide me...

  • What are the specifications of Flex usable FLV videos ?

    26 septembre 2011, par Riduidel

    I have a server which streams FLV files to a Flex client.
    In this flex client, the video timeline advances incoherently, and no video can be seen on screen (only the sound can be heard).

    My FLV file has been generated using ffmpeg, which says (about this generated file)

    Furthermore, the video plays nice in VLC.

  • ffmpeg reencoding of flv files from MAC

    I've recorded a video from a webcam on mac and now i'm trying to reencode it, but ffmpeg does not recognize audio stream :

    Is it possible to make ffmpeg to support audio stream form flv recorded on MAC ?
