  • Automated installation script of MediaSPIP

    25 avril 2011, par

    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.

    I am using FFmpegExample and have included pre compiled .so files.There are only 2 CPU structure .so files. "armeabi" and "armeabi-v7a".I already added below code in build.gradle file of app module.It didn’t worked for me.

  • TCL command prompt crashed with the error "ffmpeg.exe stopped working" with tcl version 8.0 and window 7

    9 février 2019, par M. D. P

    TCL command prompt crashed with the error "ffmpeg.exe has stopped working" with tcl version 8.0 and window 7 32 bit. my code file is "live.tcl" which is as follow :

    proc live {} {
    

    
exec ffmpeg -f dshow -s 1280x720 -i "video=Logitech HD Webcam C525" -f sdl2 - >& c:/test/temp.txt &
    

    
}
    
live

    On the other hand same my code for video capturing i.e "videocapture.tcl" works on the same tclsh command prompt on windows 7. my tcl code for "videocapture.tcl" is :

    proc videocapture {} { 
    

    
 exec ffmpeg -f dshow -t 00:00:10 -i "video=Integrated Webcam" c:/test/sample-a.avi >& temp.txt & 
    
 
    
}
    
videocapture

    error report is as follow :

  • "Amix" and "adelay" combined leads to "Error while filtering : Cannot allocate memory"

    10 février 2016, par Harald Nordgren

    I was trying to add to audio clips together (using amix) while delaying one of them (with adelay). I used the following command

    ffmpeg -i org/onclassical_demo_luisi_chopin_scherzo_2_31_small-version_ii-ending.wav \
    
-i org/all_u_had_2_say.wav -filter_complex \
    
"[1]adelay=1000[del1];[0][del1]amix" out.wav

    and get the following output

    Maybe there is some incompatibility between the streams (pcm_s16le, 44100 Hz, 2 channels vs. pcm_u8, 11025 Hz, 1 channel) that need to be handled first, but running only amix works so that doesn’t actually seem to be the case.
