Emballe médias : à quoi cela sert ?
4 février 2011, parCe plugin vise à gérer des sites de mise en ligne de documents de tous types.
Il crée des "médias", à savoir : un "média" est un article au sens SPIP créé automatiquement lors du téléversement d’un document qu’il soit audio, vidéo, image ou textuel ; un seul document ne peut être lié à un article dit "média" ; -
Les vidéos
21 avril 2011, parComme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...) -

cannot get screenshot from ffmpeg, but the url is work for vlc
6 septembre 2021, par littlefishI am a newbie on FFmpeg, and it is a very powerful tool.

I am trying to do a snapshot every 30 seconds from the RTSP stream video, therefore I find a
public RTSP URL for testing.

Here is the RTSP URL I try :
rtsp://demo:demo@ipvmdemo.dyndns.org:5541/onvif-media/media.amp?profile=profile_1_h264&sessiontimeout=60&streamtype=unicast- [a]

However, I can get the screen by using the VLC player.




But I try to do it on FFmpeg. It fails.
Do I do something wrong or anything I misunderstand ? ><

below is FFmpeg code. all are fail and get error.

ffmpeg -rtsp_transport tcp -y -i "rtsp://demo:demo@ipvmdemo.dyndns.org:5541/onvif-media/media.amp" -frames:v 1 test.jpg

# try remove `rtsp_transport`
ffmpeg -y -i "rtsp://demo:demo@ipvmdemo.dyndns.org:5541/onvif-media/media.amp" -frames:v 1 test.jpg

p.s. my computer is windows. but I get the same error on ubuntu.

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
