Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela. -

Is there any way that I can speed up the ffmpeg processing time
20 mai 2020, par Ahmed Al-RayanI am facing a problem with the processing process. I use a real joint server in a digital hosting package of $ 10 and use cloud service from Amazon s3. The problem is when uploading a video, whatever the size of the video, whether its size is 1 megabyte or 2 Giga. After the upload process, the processing process starts to upload, there is no problem But when the processing process takes a very long time so that I cannot complete it, what is the solution to that, is there a problem for me or is this process normal ?
 I use laravel-ffmpeg and through laravel queue I am cutting the video into several qualities I will attach the code to you below.



public function handle()
{
 //180p
 $lowBitrate1 = (new X264('aac'))->setKiloBitrate(613);
 //270p
 $lowBitrate2 = (new X264('aac'))->setKiloBitrate(906);
 //360p
 $midBitrate1 = (new X264('aac'))->setKiloBitrate(1687);
 //540p
 $midBitrate2 = (new X264('aac'))->setKiloBitrate(2227);
 //720p
 $highBitrate1 = (new X264('aac'))->setKiloBitrate(4300);
 //1080
 $highBitrate2 = (new X264('aac'))->setKiloBitrate(7917);

FFMpeg::fromDisk('s3')
 ->open($this->movie->path)
 ->exportForHLS()
 ->onProgress(function ($percent) {
 $this->movie->update([
 'percent' => $percent
 ]);
 })
 ->setSegmentLength(10)// optional
 ->addFormat($lowBitrate1)
 ->addFormat($lowBitrate2)
 ->addFormat($midBitrate1)
 ->addFormat($midBitrate2)
 ->addFormat($highBitrate1)
 ->addFormat($highBitrate2)
 ->toDisk('s3')
 ->save("public/Movies/{$this->movie->id}/{$this->movie->id}.m3u8");
}//end of handle

FFMPEG "Segmentation fault" with network stream source
23 décembre 2023, par user11186466I use release : 4.2.2 (static) from "https://johnvansickle.com/ffmpeg/"



Final code will be on "Amazon AWS lambda"



Goal : use a url stream and add watermak



Link to video : https://feoval.fr/519.mp4



Link to Watermak : https://feoval.fr/watermark.png



./ffmpeg -i "https://feoval.fr/519.mp4" -i "./watermark.png" -filter_complex "overlay=W-w-10:H-h-10:format=rgb" -f "mp4" -movflags "frag_keyframe+empty_moov" -pix_fmt "yuv420p" test.mp4




return "Segmentation fault"



I have the same error on my computer and on AWS Lambda server



./ffmpeg -i "https://feoval.fr/519.mp4" -f "mp4" -movflags "frag_keyframe+empty_moov" -pix_fmt "yuv420p" test.mp4




work (but not watermak)



./ffmpeg -i "./519.mp4" -i "./watermark.png" -filter_complex "overlay=W-w-10:H-h-10:format=rgb" -f "mp4" -movflags "frag_keyframe+empty_moov" -pix_fmt "yuv420p" test.mp4




work (but not with stream)



Thanks you very much !

How do I combine mkv and mka file using fluent-ffmpeg ?
17 mai 2020, par YaSh ChaudharyI have two Amazon S3 bucket file urls , one is for mkv file(video) and other one for mka(audio).



I am trying to merge audio and video in one file and upload it to S3 but following function doesn't seems to get working. Not getting error also.



client.request({ method: 'GET', uri: uri }).then((response) => {
 const mediaLocation = response.body.redirect_to
 media.push(mediaLocation)
 if(media.length > 1) {
 ffmpeg(media[0])
 .addInput(media[1])
 .output(`${recordingSid}.mkv`)
 .on('error', function (err) {
 console.log('An error occurred: ' + err.message)
 })
 .on('end', function () {
 console.log('Processing finished !')
 var params = {
 Body: fs.createReadStream(`${recordingSid}.mkv`),
 Bucket: config.aws.bucketname,
 Key: `${recordingSid}.mkv`,
 }
 s3.upload(params, function (err, data) {
 //handle error
 if (err) {
 console.log('Error', err)
 }

 //success
 if (data) {
 console.log('Uploaded in:', data.Location)
 }
 })
 })
 }
 })




My ultimate goal is to upload this output to S3 bucket.
