  • Ajouter notes et légendes aux images

    7 février 2011, par

  • AVI to MP4 - ffmpeg conversion

    4 juin 2014, par Emmanuel Brunet

    I’m running a debian 7.5 machine with ffmpeg-2.2 installed following these instructions

    Issue

    I’m trying to display a mp4 video inside my browser. The original file has an AVI container format. I can successfully convert it to mp4 and the targetfile is readable (video + sound) with the totem movie player. So I thought everything would be OK displaying the bellow page

    HTML5 web page

        
    

    

    
<video width="640" height="480" controls="controls">
    
  <source src="/path/to/output.mp4" type="video/mp4">
    
<h3>Your browser does not support the video tag</h3>
    
</source></video>

    Input probe

    $ ffprobe -show_streams input.avi
    

    
  Duration: 00:08:22.90, start: 0.000000, bitrate: 1943 kb/s
    
    Stream #0:0: Audio: mp3 (U[0][0][0] / 0x0055), 48000 Hz, stereo, s16p, 64 kb/s
    
    Stream #0:1: Video: mpeg4 (Advanced Simple Profile) (XVID / 0x44495658), yuv420p, 720x540 [SAR 1:1 DAR 4:3], 1870 kb/s, 29.97 fps, 25 tbr, 29.97 tbn, 25 tbc

    Convert

    $ ffmpeg -y -fflags +genpts -i input.avi -acodec copy -vcodec copy ouput.mp4

    Html browser

    Opening the above html file plays sound but no video is displayed.

    When I use other .mp4 files, videos succesfully displayed so I’m sure I face a conversion issue.

    Not : I’ve tryed a lot of other ffmpeg options but without success.

    Any idea ?

    Thanks in advance.

  • Ffmpeg ./configure not found

    7 juin 2016, par Justin Tullock

    I’m trying to install ffmpeg with libvpx & libx264 on my vps. Centos07. I’ve followed these instructions https://trac.ffmpeg.org/wiki/CompilationGuide/Centos to the T.

    Now when I try to run

    cd ~/ffmpeg; ./configure --enable-libvpx --enable-gpl --enable-libx264

    it returns

    -bash: ./configure: No such file or directory

    When I try ffmpeg -v

    ffmpeg: error while loading shared libraries: libx264.so.148: cannot open shared object file: No such file or directory

    and ldd $(which ffmpeg) returns
