    25 avril 2011, par

    Afin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
    Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

  • Prevent output in error log when ffmpeg job is initiated via PHP's shell_exec()

    19 janvier 2016, par Jake

    I’m getting the entire output of the ffmpeg command printed to my server’s error.log — but as far as I can tell, the jobs complete successfully with no error.

    Is there any way to suppress the output ? I have seen people append stuff like >/dev/null 2>/dev/null & to their command, however that forces the command to return immediately and the job runs in the background. Unfortunately, I need the job to run in the foreground, because I need to do stuff with the output once the job is done.

    Here’s the command I am running...

    shell_exec('ffmpeg -i input.mp4 -f mp4 -c:v libx264 -preset slow -crf 24 -s 1280x720 -c:a libfdk_aac -profile:a aac_he -ar 22050 -b:a 64k -movflags +faststart output-1280x720.mp4');

    Here’s the output I am seeing...

  • ffmpeg : corrupt audio in usage of avfoundation

    3 janvier 2016, par Andy

    I am trying to record my desktop screen (MacBook Pro (Retina, 15-inch, Mid 2014), OSX 10.10.5) with audio. First, I have to find the devices for recording, video:1 and audio:0 in my case.

    User@User-MacBook-Pro:~/test$ ffmpeg -hide_banner -f avfoundation -list_devices true -i ""

[AVFoundation input device @ 0x7ff19a422320] [2] Soundflower (64ch)
    
: Input/output error

    Then I run to capture the screen :

    ffmpeg -f avfoundation -i "1:0" out_desktop.mkv

    and the audio of the output stutters terribly.
    But if I use the second external screen (which is connect via HDMI) :

    ffmpeg -f avfoundation -i "2:0" out_ext.mkv

    Then I have no audio problems.

    So, what could be the cause of this behaviour ? Somehow the video device "Capture screen 0" causes the audio stutter.

    Here are the full outputs of the two commands above, Screen 0 :

    EDIT

    The main differences between the two (lengthy) outputs above via

    wdiff -n output1 output2 |colordiff

    is the resolution ([-2880x1800,-] {+2560x1080,+}) and the resulting MB rate ([-(20340000000)-] {+(10880000000)+}). So, what could increase the performance of ffmpeg ?
