  • 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.
