  • Déploiements possibles

    31 janvier 2010, par

    Deux types de déploiements sont envisageable dépendant de deux aspects : La méthode d’installation envisagée (en standalone ou en ferme) ; Le nombre d’encodages journaliers et la fréquentation envisagés ;
    L’encodage de vidéos est un processus lourd consommant énormément de ressources système (CPU et RAM), il est nécessaire de prendre tout cela en considération. Ce système n’est donc possible que sur un ou plusieurs serveurs dédiés.

  • ffmpeg - when cutting video, last frame is green [on hold]

    4 juillet 2016, par Mister Fresh

    In a php web app, the user can upload a video and cut it in samples. Php launches a shell command with shell_exec() to start ffmpeg and cut the video.

    It works except that the last frame shows a green splash in the cut sample.

    Server is on linux. In dev environment (mac) with latest ffmpeg, the problem cannot be reproduced.

    Command is the following :

    ffmpeg -i /var/www/user_dir/web/projects/127472/cuts/1146 -ss 00:00:45 -t 15 -vcodec libx264 -s 640x360 -strict experimental -v quiet -y /var/www/user_dir/web/projects/127472/cuts/sample1954_small.mp4

    Console output :

    At this step I have two problems :
    first is a warning during execution
    deprecated pixel format used, make sure you did set range correctly
    The second is the video do not work correctly in VLC (video is "black") but it work in wmp...

    Then I add an empty audio track :

    ffmpeg -threads 8 -f lavfi -i aevalsrc=0 -i "D:\Records\2013-10-11_115453\PublishingDirectory\Temporary_WithtoutAudio1.mp4" -vcodec copy -b:v 1500k -acodec aac -map 1:0 -map 0:0 -shortest -strict experimental -y "D:\Records\2013-10-11_115453\PublishingDirectory\Temporary1.mp4"

    After that I concat this video to others using complex filter .
    When I concat my videos I have this message :

    [output stream 0:1 @ 0451d3a0] 100 buffers queued in output stream 0:1, something may be wrong.

    And when i Watch the result my video freeze after the image insertion for a approximatly a seconde .
    perhaps it is not related
    I don't know ...

    Here my concat command and execution log

    D:\test>ffmpeg.exe -threads 8 -i "D:\Records\2013-10-11_115453\PublishingDirectory\Temporary0.mp4" -i "D:\Records\2013-10-11_115453\PublishingDirectory\Temporary1.mp4" -i "D:\Records\2013-10-11_115

  • Record sound with ffmpeg on ubuntu 12.04 [closed]

    27 juin 2012, par vzybilly

    I have been working for a few days on trying to get ffmpeg to record sound, a short list of what I've tried :

    #Crappy screen grab
    
#ffmpeg -f x11grab -s "1366x768" -r "24" -i :0.0 -f mp4 ./out
    
#awesome screen grab, grabbing sound but non out.
    
#ffmpeg -f x11grab -s "1366x768" -r "24" -i :0.0 -f alsa -ac 2 -i pulse -vcodec libx264 -s "1366x768" -acodec libmp3lame -ab 128k -threads 0 -f mp4 ~/Desktop/vid
    
#audio test, no audio in file.
    
#ffmpeg -f alsa -ac 2 -i pulse -acodec libmp3lame -ab 128k -threads 0 -f mp3 ./test.mp3
    
#awesome screen grab.
    
#ffmpeg -f x11grab -s "1366x768" -r "24" -i :0.0 -threads 0 -sameq -an -f mp4 ~/Desktop/vid[/CODE]I'm running ubuntu 12.04 from beta(ish)

    it would be awesome if someone could help me get this to work all in one line or (the way i'm going) multiple instances of ffmpeg (screen grab, microphone, program)

    I have also tried the pavucontrol with doing the monitoring of when recording audio, but that does not help either.

    Thanks for all of your help, vzybilly 

    EDIT :
    This one crashed.
