  • ffmpeg - Incompatible sample format '(null)'

    17 juin 2012, par abrahab

    I convert videos from different sources with ffmpeg to mp4 with libx264 codec. After conversation time to time I got incorrect format error when trying to load already converted video with ffmpeg : Incompatible sample format '(null)' for codec 'aac', auto-selecting format 's16'

    Seems, it is audio stream problem with aac codec ? How to fix or how to convert videos to mp4 to be sure that I will not get the following error ? Maybe somehow need to specify audio format at the ffmpeg convert command ?

    ps. Video must work at Iphone/Ipad.
    pps. the main problem, that such videos with the following error can not be pseudo-streamed with nginx (got 500 Error)
    ppps. and sorry for my bad english, please, correct my text if need. thanks.

  • FFMpeg video recorder - Android

    30 avril 2014, par Ganesh

    I’ve used ffmpeg video recorder for android.

    it has used videocodec as MPEG4.

    private int videoCodec = avcodec.AV_CODEC_ID_MPEG4;

    video is showing android and iphone device. but video not playing on browser only audio playing on browser.

    I’ve checked HTML5 video requires MP4 videos with H264 video codec and AAC audio codec

    Chrome doesn’t display html5 video but plays audio

    I’ve changed videocodec as below

    private int videoCodec = avcodec.AV_CODEC_ID_H264;

    My question is,

    when i use Mpeg4, video croping time is less.
    But when i use H264 , video croping time takes more.

    How to reduce the video croping time when use H264 or anyother videocode support to browser and minimum processing time for video croping.?
