    openid est en perdition, mais evitons au moins de pourir la vie des users avec ce lien qui choppe la tabulation entre les deux input : on le deplace après le mot de passe.

  • 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

    Also the ffmpeg version is

    Any ideas as to why this would be happening ?

  • FFmpeg AVI recording for H264 @ 1fps not working

    27 février 2012, par Alam

    I am recording H.264 (640x480 @1fps 10seconds) in avi container using FFMPEG. When I play the recorded file in VLC, it plays only first frame and rest of the frames are not played. I am getting

    main warning : late picture skipped (555293 > -305)

    Is there something I am doing wrong ? Same code works perfectly for frame rate above 3
