  • ffmpeg audio conversion : encoder pcm_u8 working pcm_s8 not

    1er août 2016, par patszn

    I need to convert audio inside video to 8 Bit signed PCM. I try it like this :

    C:\Users\E\Desktop\ffmpeg-20160731-04da20e-win32-static\bin>ffmpeg -i minions.mp4 -vcodec mjpeg -s 800x480 -acodec pcm_s8 -ac 1 out.avi

    ffmpeg can not write a header for output file. I want to mention that if audio encoder is selected to pcm_u8 everything works fine.

  • FFMPEG Convert from mov, mjpeg codec error

    30 août 2011, par vitel

    I've a problem when i try to convert a .mov to a .webm with ffmpeg... I've no problems from any others video format.

    I've enable the Quicktime formats "—enable-zlib" and with the "ffmpeg -formats" command i get .mov files as encode or decode.

    When i try to transform a video i get this :

  • ffmpeg conversion skips audio

    10 mars 2012, par user504879

    While converting a video to mp4 format using ffmpeg the audio gets skipped because of which the audio goes out of sync with the Video.

    One can have a look at the following Video :
    https://vialogues.com/vialogues/play/486

    I am using the following options for conversion

    /usr/local/bin/ffmpeg -y -i $inputfile -acodec libfaac -ar 44100 -ab 96k -vcodec libx264 -level 41 -bufsize 20000k -maxrate 25000k -g 250 -r 20 -s 480x270 -coder 1 -flags +loop -cmp +chroma -partitions +parti4x4+partp8x8+partb8x8 -flags2 +dct8x8+bpyramid -me_method umh -subq 7 -me_range 16 -keyint_min 25 -sc_threshold 40 -i_qfactor 0.71 -rc_eq 'blurCplx^(1-qComp)' -bf 16 -b_strategy 1 -bidir_refine 1 -refs 6 -crf 25 -deblockalpha 0 -vpre medium -deblockbeta 0 $outputfile
