MediaSPIP Player : problèmes potentiels
22 février 2011, parLe lecteur ne fonctionne pas sur Internet Explorer
Sur Internet Explorer (8 et 7 au moins), le plugin utilise le lecteur Flash flowplayer pour lire vidéos et son. Si le lecteur ne semble pas fonctionner, cela peut venir de la configuration du mod_deflate d’Apache.
Si dans la configuration de ce module Apache vous avez une ligne qui ressemble à la suivante, essayez de la supprimer ou de la commenter pour voir si le lecteur fonctionne correctement : /** * GeSHi (C) 2004 - 2007 Nigel McNie, (...) -

FFMPEG no audio in final output [migrated]
16 juin 2015, par MaverickI have the following FFMPEG command working.
ffmpeg -y -i slide.mp4 -f lavfi -i "color=c=black:s=1920x1080:r=25:d=1" -filter_complex "[0:v] setpts=PTS-STARTPTS [main]; \
[1:v] trim=end=3,setpts=PTS-STARTPTS [pre]; \
[1:v] trim=end=3,setpts=PTS-STARTPTS [post]; \
[pre][main][post] concat=n=3:v=1:a=0 [out]" -map "[out]" output.mp4It appends black frames at the start and end of the video. However, the output file does not contain the audio from the input file.
Any pointers to the problem will be highly appreciated.

How can I get the final size after transcripting a video to stream it with fluent-ffmpeg ?
5 avril 2018, par G. ManukyanI am trying to stream a video using
createReadStream
and usingpipe(res)
in node.js and it works fine if the file doesn’t need transcoding (mp4, webm).With mkv files I am using fluent-ffmpeg to transcode it on the fly, but the problem is that I can’t go back and forward in the html video player.
download = function(file, req, res) {
const range = req.headers.range
const parts = range.replace(/bytes=/, "").split("-")
const start = parseInt(parts[0], 10);
const end = parts[1] ? parseInt(parts[1], 10) : file.length - 1
res.setHeader('Content-Type', 'video/webm')
res.setHeader('Accept-Ranges', 'bytes');
res.setHeader('Content-Length', 1 + end - start);
res.setHeader('Content-Range', `bytes ${start}-${end}/${file.length}`);
res.statusCode = 206;
var stream = file.createReadStream({start, end})
ffmpeg(stream)
.videoCodec('libvpx')
.audioCodec('libvorbis')
.videoBitrate('512k')
.format('webm')
.on('start', () => {
console.log('transcoding...')
})
.on('error', (err, stdout, stderr) => {
console.log(err.message, err, stderr);
})
.on('progress', function(progress) {
console.log(progress);
})
.on('end', function(filenames) {
console.log("Finished transcoding.");
})
.pipe(res);
}I think that comes from the fact that we don’t know in advance the size of the final transcoded file so the range we send in the headers is wrong and somehow make the video player "limited".
What can be a workaround to this problem ?
