    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.

  • ffmpeg Too many bits per frame requested

    18 novembre 2016, par GRaecuS

    I am using ffmpeg to convert videos to mp4 format. Everything works fine except with MOV format.

    The command I use for everything is :

    ffmpeg -i input.mov -strict experimental -sameq -s vga -aspect 1.7777 -vcodec libx264 -preset fast -crf 22 -y output.mp4

    but the output I keep getting is :

  • Scroll one image top to bottom

    17 septembre 2018, par Cyber

    I am trying to scroll an image top to bottom like this video :
    https://youtu.be/8GCrrsiBLzs

    And here’s what I tried

    ffmpeg -loop 1 -t 24 -i "image.jpg" -filter_complex "color=000000:s=640x360[bg]; [bg][0]overlay=shortest=1:y='min(0,-(t)*26)'" -y out6.mp4

    But video didn’t created, ffmpeg close immediately and returns following results :

  • G.I. Joe Custom Multimedia

    30 mars 2012, par Multimedia Mike — General

    I received this 3-disc set of G.I. Joe CD-ROMs today :



    Copyright 2003, and labeled as PC ONLY. Each disc claims to have 2 episodes. So are these some sort of video discs ? Any gaming elements ? I dove in to investigate.

    So, it turns out that there are some games on these discs, done in Flash Player (which tells me that these were probably available on the web at some point). Here’s a shooting gallery game from the first disc :



    As promised by the CD-ROM copy, the menu does grant access to 2 classic G.I. Joe episodes. Selecting either one launches this :



    Powered by C-ezy ? Am I interpreting that correctly ? Anyway, the video player goes fullscreen and looks fine (given the source material). I can’t capture screenshots and controls are limited to : space for pause, ESC to exit player, and up/down to control volume. No seeking and certainly no onscreen controls. Pretty awful player.

    Studying the first disc, I find a 550 MB file with the name 5859Hasbro.egm. Coupled with ep58.cfg and ep59.cfg files in the same directory, I gather that the disc has G.I. Joe episodes 58 and 59 (though the exact episodes, “There’s No Place Like Springfield” parts 1 and 2, are listed on Wikipedia as being episodes 154 and 155 ; but who’s counting ?). The cfg files contain this text :

    ep58.cfg :
    EGM_GIJOE.exe
    5859Hasbro.egm /noend /track:0 /singletrack
    

    ep59.cfg :
    EGM_GIJOE.exe
    5859Hasbro.egm /noend /track:1 /singletrack

    The big EGM file starts with the string “Egenie Player”. After that, I see absolutely no clues. The supporting EGM_GIJOE.exe file has some interesting strings : “Decore Bits Per Pixel” (I know I have seen “Decore” used to mean “decoding core” in some libraries), “Egenie Player – %s, Version :%s”, “4th June 2002″, a list of common FourCC tags seen in AVI files, “Brought to you by Martin, Patrick Bob and Bren” (do you suppose “Patrick Bob” is one person’s name ?), a list of command line options…

    Aha ! A URL : http:\www.e-genie.tv (yep, backslashes, not forward slashes). e-genie.tv seems to redirect to mygenie.tv, which… doesn’t appear to be strictly related to video technology these days.
