    PHP et safe_mode activé
    Une des principales sources de problèmes relève de la configuration de PHP et notamment de l’activation du safe_mode
    La solution consiterait à soit désactiver le safe_mode soit placer le script dans un répertoire accessible par apache pour le site

  • Conversion of .dav [Ubuntu]

    3 juin 2018, par Dauas

    I’ve installed ffmpeg on a Ubuntu Linux Amazon EC2 Server and have a Lorex FLIR NVR directly FTP transferring .DAV files to it. In this system a Java program would then tell the EC2 to convert the .dav to but this is where the problems begin, FFMPEG fails to convert the .dav file and to my surprise there is no Codec for .dav (Though I see mention of it once having been supported). I reach out for a solution to this File Format problem, unfortunately the .dav files are a given as the NVR I have is incapable of transfering any other data type over the web, but what is the best way to convert a .dav file on a linux machine ? My Java program has full access to the Shell. It would also be incredibly helpful if anybody were to know how to get their hands on a .dav codec I could test with ffmpeg. I very much value all of your time helping me on this issue.

  • Relocated ffmpeg example files fail

    17 novembre 2020, par CT99

    I'm trying to use some ffmpeg calls in my own program, the basis of which I'm editing the ffmpeg example program remuxing.c. I'm trying to use some of the ffmpeg calls in my own program.

    


    I'm running Ubuntu 18.04.5 on a generic Linux box.

    


    To help better understand what I've done and where I've having problems, I'll out line what I've done and what is not working.

    


    Steps I've successfully completed :

    


    — I've have downloaded the ffmpeg code base and example files

    


    — Next I did a './configure', then 'make', then 'make install' and 'make examples' to make the libraries and examples

    


    — I tested some of the examples and they ran fine from the default install directory

    


    — specifically, when I test remuxing.c in the original ffmpeg downloaded dir — compile and run — it works fine

    


        ./remuxing /data/iphone-h264.m4v /tmp/test15.ts


    


    — this creates a .ts output file that I can test and is readable by vlc

    


    Having ensured that I correctly compiled and tested ffmpeg source and its example files, I next move to working my own program based on the example remuxing.c

    


    — I copied the original remuxing.c into my own test directory structure

    


    — I make it by running this to link in the required ffmpeg libraries (I think)

    


        cc -DLINUX -o remuxing remuxing.c -I ../ffmpeg/libavformat -lavformat -I ../ffmpeg/libavcodec -lavcodec -I ../ffmpeg/libswresample -lswresample -I ../ffmpeg/libavutil -lavutil -lpthread -lm


    


    — however when I try to generate a test16.ts file (to know it is different from the one I created before) I get an error :

    


        ./remuxing /data/iphone-h264.m4v /tmp/test16.ts
    Could not open input file '/data/iphone-h264.m4v’ Error occurred: Invalid data found when processing input


    


    This is the exact same video file the same program converted from the installed doc/examples directory.

    


    QUESTION — why is this happening — what am I doing wrong ?

    


    I guess I may not be properly linking in the ffmpeg libraries ?? — but I'm not sure what I'm doing wrong.

    


    I can also post my makefiles if that would help.

    


    Would be most appreciative for any help — thank you in advance.

    


  • Using Python to make a terminal-based YouTube audio streamer

    11 août 2015, par Tyson Berry

    I want to make a terminal-based program that streams YouTube audio for easy listening to music. I’m aware that I’d have to use a converter like ffmpeg to extract the mp3 audio and an audio player like Foobar2000, I’m just unsure how to make it all work together.

    I have an idea for commands etc which is here. (Excuse my crude use of MS Paint)

    As you can see yap (YouTube Audio Player, a working title) is the command used in front of a YouTube URL to tell the program what video to fetch. It then fetches the title of the video from the YouTube page’s source, which is listed in a text file on the desktop along with the URL. The song is then loaded and played through the audio player which is displayed in the terminal using the song time. When the song has ended, you can see the user has typed list. List opens up the list on the desktop, which displays all the songs previously entered in the program. The user can then select a number and play the corresponding song from the list.

    I have found this, which is outdated yet relevant.
