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.

20 mai 2019, par SulliI’m trying to download a specific part of a youtube video with this code :
step=`youtube-dl -g -f 'bestvideo[ext=mp4]' https://www.youtube.com/watch?v=pMntMsHTDZ0`
ffmpeg -nostdin -i "$step" -ss 00:00:10.00 -t 00:00:02.00 -c copy frames/out.mp4but I’m getting this error :

I don’t understand this error, and this code has worked for tens of videos I’ve downloaded before.
How to fix this or get more information on the error ?

How to make mp4 rendering visible on Mac ?
24 octobre 2022, par JánosGenerating mp4 from gif like this :


await new Promise<void>((resolve, reject) => {
 ffmpeg
 .input(`/tmp/input_${name}.gif`)
 .outputOptions([
 '-c:v libx264',
 '-movflags +faststart',
 '-movflags frag_keyframe+empty_moov',
 ])
 .noAudio()
 .output(`/tmp/output_${name}.mp4`)
 .on('end', () => {
 console.log('MP4 video generated')
 resolve()
 })
 .on('error', (e) => {
 console.log(e)
 reject()
 })
 .run()
 })
</void>


will generate mp4, but can be watch only in Chrome, not in Safari or Quicktime Player.


We tried many other option like this :


'-pix_fmt yuv420p',
'-vf "scale=trunc(iw/2)*2:trunc(ih/2)*2"',



but it raise an error :


Error reinitializing filters!
Failed to inject frame into filter network: Invalid argument

Animated Gif using PHP 5 and ffmpeg [closed]
1er décembre 2012, par user1828200I make an Animated Gif, by download a video from youtube with youtube-dl and then convert it into AVI with
ffmpeg
and then make animated gif throughconvert
. It works, but speed is very slow.Here is my code
Youtube Download :
shell_exec("youtube-dl -o JNJNoaIU7qs.flv --format=5 --audio-quality=9 http://www.youtube.com/watch?v=JNJNoaIU7qs);
Convert to AVI , because I want to make Small Gif so time manipulation is not done with youtube-dl thats why i convert avi with time manipulation
shell_exec("ffmpeg -i JNJNoaIU7qs.flv -sameq -ss 00:00:5 -t 00:00:10 JNJNoaIU7qs.avi");
Make Gif
shell_exec("convert -quiet -delay 0 JNJNoaIU7qs.avi JNJNoaIU7qs.gif");
It creates the GIF files, but it is very slow, how can I increase the speed of conversion ?
