  • Convert a video to MP4 (H.264/AAC) with ffmpeg

    5 décembre 2015, par user176455

    If I don’t make a mistake, Safari currently need MP4 (H.264/AAC) video encoded for the HTML5 <video></video> element.

    So I tried to convert a video to this format with ffmpeg. However when I enter the shell command ffmpeg -i video.flv video.mp4, the returned error is :

    Seems stream 0 codec frame rate
    differs from container frame rate :
    2000.00 (2000/1) -> 29.92 (359/12) Input #0, flv, from ’video.flv’ :
    Duration : 00:05:01.20, start :
    0.000000, bitrate : 66 kb/s
    Stream #0.0 : Video : h264, yuv420p, 320x240 [PAR 1:1 DAR 4:3], 66 kb/s,

    Stream #0.1 : Audio : aac, 22050 Hz, stereo, s16 Output #0, mp4, to

    Stream #0.1 : Audio : 0x0000, 22050 Hz, stereo, s16, 64 kb/s Stream
    mapping : Stream #0.0 -> #0.0
    Stream #0.1 -> #0.1 Unsupported codec
    for output stream #0.1

    An AAC codec is required but I’m quite newbie with ubuntu and I dont really now how to fix this problem. I’m using Ubuntu 9.10 Karmik Koala (for amd64).

    Thank you very much. :)

  • Compile Shotdetect on CentOS 7

    I’m migrating a service from a Debian server to a CentOS 7 one.

    The service needs the Shotdetect command (github , official site).

    I could not make it work on CentOS though I followed all steps :

      1. Install needed packages

        # yum install gd-devel libxml2-devel libxslt-devel clang libvpx libvorbis

      2. Add pthread in the CMakeList file, in TARGET_LINK_LIBRARIES, because it throws an lpthread missing in linker error

      3. Compile Shotdetect

        # FFMPEG_DIR="/root/ffmpeg_build"  ./compile.sh cmd

    the built binary will be in the built directory, you can move there and execute

    make install

    to make the binary system wide.
