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".
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 (...)

avconv : Saving MP4 is Taking Hours
4 septembre 2015, par PeregrineStudiosnot entirely sure if I should post this on askubuntu or stackoverflow. Posted on askubuntu and not getting any answers. I’m hoping I can find an answer here.
I’m setting up a website where users can upload videos and share them. I’m using avconv to reduce the video size and save it twice, once as an mp4 and again as a webm.
Uploading a .MOV from a phone, the video conversion is quick and manageable.
Uploading a .mp4 from a Samsung Galaxy S3, the video conversion to webm is also quick. But, the conversion to another mp4 takes FOREVER - literally hours. Why ? Is anyone able to shed light on the problem ?
My avconv output is below.

here is a sample of srt file I am trying to merge :


1
00:00:00,000 --> 00:00:03,326
 Text 1

2
00:00:03,326 --> 00:00:09,962
 Text 2

3
00:00:09,962 --> 00:00:16,160
 Text 3

4
00:00:16,160 --> 00:00:22,223
 Text 4


any idea why the generated video does not contain the subtitle ?


Update


Based on below comment , I changed my code to use the latest ffmpeg-kit version , here is the new code


String cmd = "-i " + videoPath + " -vf subtitles=\"" + subtitlePAth + ":force_style='Alignment=10,Fontsize=18\" " + 
 outputVideoPath;

 FFmpegKit.executeAsync(cmd, new FFmpegSessionCompleteCallback() {

 @Override
 public void apply(FFmpegSession session) {

 }
 }, new LogCallback() {

 @Override
 public void apply(com.arthenica.ffmpegkit.Log log) {


 }
 }, new StatisticsCallback() {

 @Override
 public void apply(Statistics statistics) { 

 }
 });`


and here is the updated log
