Support audio et vidéo HTML5
10 avril 2011MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.
Ces technologies permettent de distribuer vidéo et son à la fois sur des ordinateurs conventionnels (...) -

31 janvier 2010, parLe chemin d’un document audio ou vidéo dans SPIPMotion est divisé en trois étapes distinctes.
Upload et récupération d’informations de la vidéo source
Dans un premier temps, il est nécessaire de créer un article SPIP et de lui joindre le document vidéo "source".
Au moment où ce document est joint à l’article, deux actions supplémentaires au comportement normal sont exécutées : La récupération des informations techniques des flux audio et video du fichier ; La génération d’une vignette : extraction d’une (...)

How to install ffmpeg
9 mars 2016, par user5913892I want to make a "mini" editor video. My goal is, cut some part of the video and then save it and also create an undo button. Now , I was looking for the best solution (This operation have to be done in a website) and I found that I have to use ffmpeg. I didn’t know if ffmpeg was already installed on my server and I use this php script to discover it :
<?php
/**
* Test script for FFmpeg
*
* @author Andycoder /wdevblog.net.ru/>
*/
ini_set('display_errors',1);
error_reporting(E_ALL);
$is_windows = strpos( php_uname(), "Windows" ) !== false;
$ffmpeg_path = !empty( $_POST['ffmpeg_path'] ) && strpos( $_POST['ffmpeg_path'], 'ffmpeg' ) !== false ? trim( $_POST['ffmpeg_path'] ) : '';
if( !$ffmpeg_path && !$is_windows ){
$ffmpeg_path = trim( shell_exec( 'which ffmpeg' ) );
}
function getCodecs( $ffmpeg_path = '' ) {
$lines = array();
$encoders = array();
exec( "{$ffmpeg_path} -codecs", $lines);
foreach ($lines as $line) {
if (preg_match('/^\s+([A-Z .]+)\s+(\w{2,})\s+(.*)$/', $line, $m)) {
$type = trim($m[1]);
if (strpos($type, 'E') !== false) {
$encoder = trim($m[2]);
if (strpos($encoder, ',') !== false) {
foreach (split(',', $encoder) as $e) {
$encoders[] = $e;
}
} else {
$encoders[] = $encoder;
}
}
}
}
sort($encoders);
return $encoders;
}
function getPHPPath(){
$is_windows = strpos( strtolower(php_uname()), 'windows' ) !== false;
if( $is_windows ){
$output = dirname(ini_get('extension_dir')) . "/php.exe";

}

ksort($info);

that return me this :
So, I have not ffmpeg installed on that server. The server should be Linux, I say this because I use one of the many website in Internet to discover it.
I know that the website say that the Webserver is Engine-x, but my company has told that is Apache (as the php script already told me). Now , I found this link http://www.mysql-apache-php.com/ffmpeg-install.htm (in Stackoverflow and many other parts) that say how to install ffmpeg in Linux, but Where should I execute these commands ? Should I use Putty ? or What ?

Audio object type 3 is not supported
3 octobre 2013, par ArdoramorI am running into an issue with a custom-built ffmpeg. Basically, its a vanilla ffmpeg with x264 and fdk-aac libs enabled. I am feeding an SDP file through ffmpeg API and get the following error while passing the info to
avcodec_open2:Audio object type 3 is not supported

I also see the error reported for not finding codec parameters for stream 1 :
Could not find codec parameters for stream 1 (Video : h264) : unspecified size
Consider increasing the value for the 'analyzeduration' and 'probesize' optionsHowever, I think that is due to me not running an actual rtp at the moment of the test.
In any case, what may be the reason for getting audio object type 3 not supported exception ?
UPDATE - Oct 02, 2013
Static ffmpeg build gives the following flags :
Static ffmpeg 2.0.1 build flag output :

fdk-aac - 0.1.2
So it seems that the same .sdp file causes Audio object type 3 error with my build but not with static but I really do not see what causes it (granted I am not an expert with ffmpeg API and may simply miss important details).
Simplified code for opening .sdp file that doesn't include error checks and logic separation :
AVFormatContext *inputContext = NULL;
av_register_all();
avformat_network_init();
avformat_open_input(&inputContext, "test.sdp", NULL, NULL);
avformat_find_stream_info(inputContext, NULL);
int inAudioStreamIdx = av_find_best_stream(inputContext, AVMEDIA_TYPE_AUDIO, -1, -1, NULL, 0);
AVStream *st = inputContext->streams[inAudioStreamIdx];
AVCodecContext *dec_ctx = st->codec;
AVCodec *dec = avcodec_find_decoder(dec_ctx->codec_id);
avcodec_open2(dec_ctx, dec, NULL); // Fails here with Audio object type 3Am I opening the sdp input improperly ?

Unable to 'make' android ndk project - build fails : [build-openh264-x86] Error 2
18 décembre 2015, par NoobNinjaI’ve attempted these two fixes I’ve found while researching the issue :
android update project --23 --/Users/ajswann/Downloads/android-sdk-macosx
make OS=android NDKROOT=/Users/ajswann/Downloads/android-sdk-macosx TARGET=android-19 ARCH=x86 clean...however neither seems to resolve the issue.
Any input/suggestions are appreciated.
P.S.
I’m running OSX - could this be an issue with attempting to run an x86 architecture on a 64 bit machine ?
