Creating farms of unique websites
13 avril 2011, parMediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...) -

FFmpeg avformat_open_input not working
30 septembre 2016, par John_ShearesThis is my first time using FFmpeg. Every type of media file that I try to open with avformat_open_input, returns "Invalid data found when processing input". I am using 32bit FFmpeg Build Version : 92de2c2. I setup my VS2015 project according to this answer : Use FFmpeg in Visual Studio. What could be going wrong with this code ?
#include "stdafx.h"
#include
extern "C"
{
#include "libavcodec/avcodec.h"
#include <libavformat></libavformat>avformat.h>
#include <libavutil></libavutil>avutil.h>
}
int main(int argc, char *argv[])
{
AVFormatContext *pFormatCtx = NULL;
avcodec_register_all();
const char* filename = "d:\\a.mp4";
int ret = avformat_open_input(&pFormatCtx, filename, NULL, NULL);
if (ret != 0) {
char buff[256];
av_strerror(ret, buff, 256);
printf(buff);
return -1;
}

Where to place the fontfile for the FFmpeg drawtext-Filter ?
18 juin 2018, par jpGerhardI’m using the precompiled FFmpeg-Android by Bravobit (via gradle :
implementation 'nl.bravobit:android-ffmpeg:1.1.5'
; based on WritingMind’s) with the intention of drawing the current timestamp/location onto a .mp4 file. I am completely new to FFmpeg and have started with Android Studio a few months ago.Information :
- IDE : Android Studio
- OS : OSX 10.13.5
My problem :
I don’t know whether the fontfile needs to be in the Application path on my Phone, in the Android Studio directory or just on a location on my MacBook (so it gets compiled when running the application).
Basic FFmpeg commands (-version, ...) are working, but I can’t seem to figure out where I have to place my fontfile.
My current command is as follows :
-i /path/to/video.mp4 -vf drawtext=fontfile=/users/shared/fonts/arial.ttf:text='Hello World' /path/to/output.mp4
I’ve tried a lot of variations and always received to following errors :
Fontconfig error : Cannot load default config file
[Parsed_drawtext_0 @ 0xecbfd420] impossible to init fontconfig
[AVFilterGraph @ 0xec9cc140] Error initializing filter ’drawtext’ with args ’fontfile=/users/shared/fonts/arial.ttf:text=Hello World’
Error reinitializing filters !
Failed to inject frame into filter network : Unknown error occurred
Error while processing the decoded data for stream #0:0
Conversion failed !Does anyone have a suggestion on how to get this to work ?
