Configuration spécifique pour PHP5

4 février 2011, par kent1

PHP5 est obligatoire, vous pouvez l’installer en suivant ce tutoriel spécifique.
Il est recommandé dans un premier temps de désactiver le safe_mode, cependant, s’il est correctement configuré et que les binaires nécessaires sont accessibles, MediaSPIP devrait fonctionner correctement avec le safe_mode activé.
Modules spécifiques
Il est nécessaire d’installer certains modules PHP spécifiques, via le gestionnaire de paquet de votre distribution ou manuellement : php5-mysql pour la connectivité avec la (...)
La sauvegarde automatique de canaux SPIP

1er avril 2010, par kent1

Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

FFmpeg av_guess_format returns NULL

12 septembre 2014, par Kage
I’m following the example code here : http://cekirdek.pardus.org.tr/ ismail/ffmpeg-docs/output-example_8c-source.html

My code is as follows :
```
fmt = av_guess_format(NULL, filename, NULL);

if (!fmt) {

        LOGE(1,"Could not deduce output format from file extension: using MPEG.\n");

        fmt = av_guess_format("mp4", NULL, NULL);

}

    if (!fmt) {

        LOGE(1, "Could not find suitable output format\n");

        exit(1);

}
```
The two times that I call av_guess_format, it is returning NULL both times.
I am calling both av_register_all() and avcodec_register_all() beforehand.

Any ideas as to why this is returning NULL ?

Thanks in advance.

FFMPEG - ignoring invalid SAR : 0/0

10 septembre 2015, par Sultanen

Im using FFMPEG to merge multiple IP cameras streams into one MPEG stream. This works well for some cameras but i get this error message when i stream a DLink MJPEG stream :

[mjpeg @ 0x7fd0f900b600] ignoring invalid SAR: 0/000:00.26 bitrate=2673.8kbits/s dup=1 drop=907    

    Last message repeated 12 times

[mjpeg @ 0x7fd0f900b600] ignoring invalid SAR: 0/000:00.26 bitrate=2673.8kbits/s dup=1 drop=920

[mjpeg @ 0x7fd0f900b600] ignoring invalid SAR: 0/000:00.26 bitrate=2673.8kbits/s dup=1 drop=934

[mjpeg @ 0x7fd0f900b600] ignoring invalid SAR: 0/000:00.26 bitrate=2673.8kbits/s dup=1 drop=947

The ffmpeg command i use is :

ffmpeg \

-i http://admin:@IP1/video.cgi?resolution=640x480 \

-i http://admin:@IP2/video.cgi?resolution=640x480 \

-filter_complex "[0:v]scale=320:240,pad=640:480[a]; [1:v]scale=320:240[b];[a][b]overlay=320[out]" \

-map [out] \

-f mpeg1video \

-r 30 http://outputURL \

ffprobe gives me the following information about the stream

[mjpeg @ 0x7fe20b80c000] Format mjpeg detected only with low score of 25, misdetection possible!

[mjpeg @ 0x7fe20c000000] ignoring invalid SAR: 0/0

Input #0, mjpeg, from 'http://admin:@IP1/video.cgi?resolution=640x480':

  Duration: N/A, bitrate: N/A

    Stream #0:0: Video: mjpeg, yuvj420p(pc, bt470bg/unknown/unknown), 640x480, 25 tbr, 1200k tbn, 25 tbc

What does this mean and how can i avoid it ?

I am able to create m3u8 file using ffmpeg from rtmp live but not able to play the file in html5 video tag & apple device

3 janvier 2014, par Nikita

I am able to create the m3u8 file by following steps :

1.Execute ffmpeg -v verbose -i rtmp://<host>:<port>/<stream> -c:v libx264 -c:a aac -ac 1 -strict -2 -crf 18 -profile:v baseline -maxrate 400k -bufsize 1835k -pix_fmt yuv420p -flags -global_header -hls_time 10 -hls_list_size 6 -hls_wrap 10 -start_number 1 <pathtofolderyouwantto>/<streamname>.m3u8

</streamname></pathtofolderyouwantto></stream></port></host>

2.Make that folder you just mentioned on ffmpeg command () to be accessible by an http url.

3.Create a simple html page to play :

<video controls="controls" width="480" height="270" src="<streamName>.m3u8"></video>

But not able to play using html5 video tag as well as in apple device.

following is my ffmpeg console output :
