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 (...) -

Using ffmpeg to increase framerate without changing duration [closed]
11 février 2024, par sarunwI want to increase the video frame rate with FFmpeg.


I found from this website, https://trac.ffmpeg.org/wiki/ChangingFrameRate, that I can use
-r
orfps filter
.

The doc said the output duration of the video would stay the same, but that is not the case in my test.


What I tried so far.


I got a video with a duration of 19 seconds at 1.45 fps (I took this number from the QuickTime app)


After using these commands, fps become 30, but the duration becomes 1 second.


ffmpeg -i <input /> -filter:v fps=fps=30 <output>
ffmpeg -i <input /> -filter:v fps=30 <output>
ffmpeg -y -r 30 -i <input /> <output>
</output></output></output>
