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 (...)

FFMPEG : how to determine which filters are supported by specific hardware acceleration contexts ?
7 juin 2020, par John AllardI'm having trouble figuring out precisely which filter graph operations are supported by each of the available hardware acceleration methods. I know, for example, that almost all of these methods perform simple operations like scaling, but what about more complicated ffmpeg filters like the new
v360filter or themestimatefilter ?


There's this page (https://trac.ffmpeg.org/wiki/HWAccelIntro) that everyone finds when researching hardware accel with ffmpeg but it mostly touched on encoding and decoding and not filtering.

How to join 2 audio files into one using either ffmpeg or eac3to ?
18 janvier 2017, par user3108268Not merge or mux into each other, because this is what I found so far, but take 2 .mp3 files e.g. 1 hour long each and join them and it becomes 1 .mp3 file with total of 2 hour long ?
I did this :
ffmpeg -i audio.mp3 -i 1.mp3 -filter_complex amerge -c:a libmp3lame -q:a 4 audiofinal.mp3But I think it encode both files into each other or something.
And there’s nothing about this at https://en.wikibooks.org/wiki/Eac3to/How_to_Use
I’d like to prefer command line solution and not Audacity or mp3DirectCut.
edit : i tried
eac3to m1.mp3+m2.mp3 1.mp3but it doesn’t join them, output audio is the length of first file. -
