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 (...) -

Split a movie so that each GIF is under a certain file size
9 novembre 2014, par Terence EdenProblem
I want to convert a long movie into a series on animated GIFs.
Each GIF needs to be <5MB.
Is there any way to determine how large a GIF will be while it is being encoded ?
Progress So Far
I can split the movie into individual frames :
ffmpeg -i movie.ogv -r 25 frameTemp.%05d.gif
I can then use
convert
from ImageMagick to create GIFs. However, I can’t find a way to determine the likely file size before running the command.Alternatively, I can split the movie into chunks :
ffmpeg -i movie.ogv -vcodec copy -ss 00:00:00 -t 00:20:00 output1.ogv
But I’ve no way of knowing if, when I
convert
the file to a GIF it will be under 5MB.A 10 second scene with a lot of action may be over 5MB (bad !) and a static scene could be under 5MB (not a problem, but not very efficient).
Ideas
I think that what I want to do is convert the entire movie into a GIF, then find a way to split it by file size.
Looking at ImageMagick, I can split a GIF into frames, but I don’t see a way to split it into animated GIFs of a certain size / length.
So, is this possible ?

Best way to split multi channel audio file in Swift [on hold]
8 mars 2016, par amkaufmanI’m currently working on an iOS project in which I need to be able to split a multi-channel .AAC file. I’m still fairly new to iOS development and Swift and am not sure if the frameworks that I have seen will be able to do this.
So far I have looked into AVFoundation and FFmpeg, but I’m still not sure if they would be able to do this.
After looking into AudioKit’s documentation I am still a bit lost on how to actually split the file into its separate channels. Where exactly should I be looking ?

How to split multiple videos 2.24 seconds before the end
15 décembre 2019, par LeendertI have a folder with 100 videos, I need to split all videos into 2, the split needs to happen 2 seconds before the end of every video.
I want to keep both parts of the video after the split.
So far I have the code below, this will trim 2 seconds from the end of every video that is in de same folder as the .bat file.
It will put the new videos inside of a folder called ’new files’.
The problem is that the length of the video is not trimmed. Only audio and video. So the last 2 seconds will just be the last frame and no audio.for %%a in ("*.mp4") do ffmpeg -i "%%a" -filter_complex "[0]trim=2,setpts=PTS-STARTPTS[b];[b][0]overlay=shortest=1" -shortest -c:a copy "newfiles\%%~na.mp4" pause
