La sauvegarde automatique de canaux SPIP
1er avril 2010, parDans 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 (...) -

Live streaming doesn't work
18 octobre 2017, par John SmithI’m using FFmpeg to capture my screen :
ffmpeg -f dshow -i video="UScreenCapture" -r 5 -s 640x480 -acodec libmp3lame -ac 1 -vcodec mpeg 4 -vtag divx -q 10 -f mpegts tcp://127.0.0.1:1234
so let it stream to somewhere. The accepter script :
error_reporting(E_ALL); /* Allow the script to hang around waiting for connections. */
set_time_limit(30); /* Turn on implicit output flushing so we see what we're getting as it comes in. */
ob_implicit_flush();
$address = '127.0.0.1';
$port = 1234;
$outfile = dirname(__FILE__)."/output.flv";
$ofp = fopen($outfile, 'wb');
if (($sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP)) === false) { echo "socket_create() failed: reason: " . socket_strerror(socket_last_error()) . "\n"; sleep (5); die; }
if (socket_bind($sock, $address, $port) === false) { echo "socket_bind() failed: reason: " . socket_strerror(socket_last_error($sock)) . "\n"; sleep (5); die; }
if (socket_listen($sock, 5) === false) { echo "socket_listen() failed: reason: " . socket_strerror(socket_last_error($sock)) . "\n"; sleep (5); die; }
if (($msgsock = socket_accept($sock)) === false) { echo "socket_accept() failed: reason: " . socket_strerror(socket_last_error($sock)) . "\n"; sleep (5); break; }
do {
$a = '';
socket_recv ($msgsock, $a, 65536, MSG_WAITALL);
fwrite ($ofp, $a);
//echo strlen($a)."\r\n";
} while (true);it seems to save the stuff to the disk OK. Now here comes the html :
I dont really know how to do this, but based on an example :
<video src="/output.flv"></video>
but it doesn’t do anything. And if I want to stream the live incoming stuff, then what’s the matter ?

How to play back a video stream on website ?
11 juillet 2012, par John SmithLets suppose I have a streaming generated from ffmpeg :
ffmpeg -f dshow -i video="UScreenCapture" -vcodec libx264 -g 30 -f mpegts tcp://127.0.0.1:1234
on the server Im catching the stuffes like this :
error_reporting(E_ALL); /* Allow the script to hang around waiting for connections. */
set_time_limit(30); /* Turn on implicit output flushing so we see what we're getting as it comes in. */
ob_implicit_flush();
$address = '127.0.0.1';
$port = 1234;
$outfile = dirname(__FILE__)."/output.flv";
$ofp = fopen($outfile, 'wb');
if (($sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP)) === false) { echo "socket_create() failed: reason: " . socket_strerror(socket_last_error()) . "\n"; sleep (5); die; }
if (socket_bind($sock, $address, $port) === false) { echo "socket_bind() failed: reason: " . socket_strerror(socket_last_error($sock)) . "\n"; sleep (5); die; }
if (socket_listen($sock, 5) === false) { echo "socket_listen() failed: reason: " . socket_strerror(socket_last_error($sock)) . "\n"; sleep (5); die; }
if (($msgsock = socket_accept($sock)) === false) { echo "socket_accept() failed: reason: " . socket_strerror(socket_last_error($sock)) . "\n"; sleep (5); break; }
do {
$a = '';
socket_recv ($msgsock, $a, 65536, MSG_WAITALL);
fwrite ($ofp, $a);
fclose ($ofp);
$ofp = fopen($outfile, 'ab');
//echo strlen($a)."\r\n";
} while (true);now Im stuck replaying this. VCL player can replay this so its got to be good, but how to put it onto a site ? I know theres HTML5 video tags, but lets not use it, because it might unsupported, and I also failed make it work every way. Is there a flash solution ? Its a dymanic stream, so no start-end !
