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 (...) -
De l’upload à la vidéo finale [version standalone]
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".

How to speed up ffmpeg when working with multiple files ?
6 mai 2019, par OBXI have
100,000
files which I need to convert from.mp3
to.wav
. However, at the moment it takes1
minute to convert10
files each of1
hour duration.Here’s what I tried :
for i in *.mp3
do
ffmpeg -i "$i" -acodec pcm_s16le -ac 1 -ar 16000 "stm/$(basename -s .mp3 "$i").wav"
doneAlso tried
GNU parallel
as well, which takes same time as well :find ./set/ -name "*.mp3" | parallel 'ffmpeg -i {} -acodec pcm_s16le -ac 1 -ar 16000 {.}.wav'
Is there a better hack to process the same in less time ?

How to increase compression speed for FFmpeg ?
30 décembre 2022, par MarotiI have used following command for compress video in android.



ffmpeg -y -i /sdcard/DCIM/Camera/VID_20150326_125017.mp4 -strict experimental -s 640x360 -r 25 -vcodec mpeg4 -b 1000k -ab 48000 -ac 2 -ar 22050 /sdcard/videokit/out.mp4




Above command is a work properly, but it's taking too much time for compression.
An 80MB video file takes around 3 minutes to compress to an 8MB file. Is there any way I can reduce this time.

how to get time bitrate, q and speed from ffmpeg using ffprobe ?
24 décembre 2016, par user2631534i im using node js that creates and start ffmpeg for restream using pipe function that works but i im unable to get from stdout.pipe ffmpeg informations about started stream : bitrate, speed, time and q.
this is what i get when i start ffmpeg using : ./ffmpeg -i http://serverip :/stream1.ts
frame= 710 fps = 65 q=1.0 Lsize = 4974kB time=00:00:28.33 bitrate = 1437.9kbits/s speed = 2.61x
and i would like to read into string this parameters so that i can write in mysql database and later show in datatables info...how to get frame, fps, q, time, bitrate and speed value into javascript variable so that i can use it later ?
i im starting ffmpeg using this :
function listener(id, stream_url) {
/* LISTENER - ffmpeg */
streams[id].on('close', function() {
/* START - stream */
stream(id, stream_url);
});
}
function stream(id, stream_url) {
/* START - ffmpeg */
streams[id] = child_process.spawn(process.env.PWD + "/node_modules/ffmpeg-static/bin/linux/x64/ffmpeg", [
"-re", /* STREAM - realtime */
"-y", /* OVERWRITE - output file */
"-hide_banner", /* BANNER - hide */
"-loglevel", "quiet", /* LOG - hide */
"-i", stream_url, /* STREAM - source */
"-vcodec", "copy",
"-reset_timestamps", "1",
"-movflags", "frag_keyframe+empty_moov",
"-f", "mpegts",
"-"
], { detached: false });
/* LISTENER - ffmpeg */
listener(id, stream_url);
}
/* LOOP - throught all streams */
for (var i in rows) {
/* CHECK - ffmpeg */
if (!streams[rows[i].id]) {
/* START - stream */
stream(rows[i].id, rows[i].stream);
};
};And showing stream using :
streamRoutes.get('/stream2', function(req, res) {
/* STREAM - header */
res.writeHead(200, {
'Content-Type': 'video/H264'
});
/* PIPE - stream to client */
streams[2].stdout.pipe(res);
ffprobe(streams[2].stdout, { path: ffprobeStatic.path }, function (err, info) {
console.log(info);
});}) ;
i try using ffprobe input stream as stdout from ffmpeg that is read from memory but i get undefined in console.log....
UPDATED QUESTION :
i save file using this code to HDD and then read frpm fluent-ffmpeg-extended metadata and i im getting correct JSON data (duration, bitrate, resolution, time etc...) but i would like not to save stream to HDD to get informations...i would like to get from memory stream and get this informations...but fluent-ffmpeg-extended accept only local input file on HDD not stream (http link), how can i enter stream link into fluent-ffmpeg to get this infomations from memory (stdout.pipe) ?
var inputfile = "http://myserverip/stream/ -vcodec copy -f mpegts 1.ts";
var exec = require('child_process').exec;
exec("/root/mediaxtream-codes/node_modules/ffmpeg-static/bin/linux/x64/ffmpeg" + ' -i ' + inputfile, function(err, stdout, stderr) {
console.log(stdout);
});
function check() {
var Metalib = require('fluent-ffmpeg-extended').Metadata;
var metaObject = new Metalib("1.ts", function(metadata, err) {
console.log(require('util').inspect(metadata, false, null));
});
setTimeout(check, 1000);
};
setTimeout(check, 1000);And form console.log in terminal i get correct informations every seconds :
