Déploiements possibles
31 janvier 2010, parDeux types de déploiements sont envisageable dépendant de deux aspects : La méthode d’installation envisagée (en standalone ou en ferme) ; Le nombre d’encodages journaliers et la fréquentation envisagés ;
L’encodage de vidéos est un processus lourd consommant énormément de ressources système (CPU et RAM), il est nécessaire de prendre tout cela en considération. Ce système n’est donc possible que sur un ou plusieurs serveurs dédiés.

IE9+ not playing portrait video in HTML5 video tag
12 avril 2017, par ptrnFor some reason I can’t get IE9/10 to play video that is taller than wide, when using HTML5 video tags.
Demo :
http://s.l6.no/demo/video+html5/The demo shows one video scaled down from 1280x720, which plays perfectly fine in all tested browsers, and one video scaled down from 720x1280 which plays for all browsers but IE9/10.
Tested and works for :
- Chrome 26, Windows 7 64-bit
- Chromium 24, Ubuntu 64-bit
- Firefox 14, Windows 7 64-bit
Tested and does not work for :
- Internet Explorer 9, Windows 7 64-bit
- Internet Explorer 10, Windows 7 64-bit
I’m using FFmpeg to code the videos to MP4(x264) and WebM(VP8), with the current command dummed down to this :
ffmpeg -i in.mp4 -vcodec libx264 -pix_fmt yuv420p -y -b:v 4000k out.mp4
The lack of profile settings would be my first point, but since the other video is playing just fine, I can’t see why it should matter.
Any ideas ?
Edit : soft rotating the video isn’t really an option, as the user is to be able to download the video to play offline. I could transcode an extra version just for IE, but come on, there’s gotta be another way, no ?

How can I extract images from an MPTS video(which has 4 videos in it) from each and every video using a single command ?
21 octobre 2019, par geo-freakI have an MPTS video file, which has 4 videos in it. I want to extract images from each video and store them in a directory separately. I am using ffmpeg, I have seen references from previous solved questions.
I used below command to extract frames.
ffmpeg -threads 8 -i input.ts -s 400x222 -qscale:v 4 -start_number 0 -vf fps=1 /storage/frames/input_1//%d.jpg /storage/frames/input_2//%d.jpg /storage/frames/input_3//%d.jpg /storage/frames/input_4//%d.jpg
But frames extracted only for first video in MPTS stream. How can I achieve using this using a single ffmpeg command ?
