Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela. -

FFmpeg command works locally but not on Azure Batch Service
10 août 2018, par ElgertI have a command that generates a video with background and text on it with FFmpeg and would like to render it using Azure Batch Service. Locally my command works :
./ffmpeg -f lavfi -i color=c=green:s=854x480:d=7 -vf "[in]drawtext=fontsize=46:fontcolor=White:text=dfdhjf dhjf dhjfh djfh djfh:x=(w-text_w)/2:y=((h-text_h)/2)-48,drawtext=fontsize=46:fontcolor=White:text= djfh djfh djfh djfh djf jdhfdjf hjdfh djfh jd fhdj:x=(w-text_w)/2:y=(h-text_h)/2,drawtext=fontsize=46:fontcolor=White:text=fh:x=(w-text_w)/2:y=((h-text_h)/2)+48[out]" -y StoryA.mp4
while the one generated programatically with C# and added as a task in batch service retursn failure :
cmd /c %AZ_BATCH_APP_PACKAGE_ffmpeg#3.4%\ffmpeg-3.4-win64-static\bin\ffmpeg -f lavfi -i color=c=green:s=854x480:d=7 -vf "[in]drawtext=fontsize=46:fontcolor=White:text=dfdhjf dhjf dhjfh djfh djfh:x=(w-text_w)/2:y=((h-text_h)/2)-48,drawtext=fontsize=46:fontcolor=White:text= djfh djfh djfh djfh djf jdhfdjf hjdfh djfh jd fhdj:x=(w-text_w)/2:y=(h-text_h)/2,drawtext=fontsize=46:fontcolor=White:text=fh:x=(w-text_w)/2:y=((h-text_h)/2)+48[out]" -y StoryA.mp4
The ffmpeg configuration works, and also the Pool as I’ve already tested it with simpler ffmpeg commands which had input and output files. This command doesnt have input file, maybe that is part of the problem ?
Thank you

ffmpeg encoding .mp4 fails in safari when hosted from s3. handbrake encoded video works first time
11 juin 2018, par Simon RogersThe mp4 videos I’ve encoded with ffmpeg work perfectly in Safari if stored locally, but break if hosted from s3. I have tried countless encoding settings to no avail.
However having just run a mov quickly through Handbrake and ticking ’optimise for web’ and encoding baseline @ 4.0, this has worked perfectly first time.
I don’t understand what could be going wrong with my ffmpeg encoding.
Things I have noticed about files from two separate encoders which work :
They both have
yuv420p(tv, bt709)
whereas ffmpeg is just sayingyuv420p
– this is the only thing I can identify from ffprobe that is consistently different.I have done a fresh install of ffmpeg to no avail :
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew install ffmpeg --with-fdk-aac --with-ffplay --with-freetype --with-libass --with-libvorbis --with-libvpx --with-opus --with-x265
This error appears in all the files I have encoded with ffmpeg :
Unsupported codec with id 0 for input stream 1

FFMPEG command works in shell ! but not in my node.js
29 juillet 2021, par Kuno KimWhen my ffmpeg command is built by my node.js application it does not run.



error



Unrecognized option 'ss 3.2 -t 1.9 -i videoplayback.mp4 -vf fps=15,scale=240:-1:flags=lanczos,palettegen palette.png'.




command



ffmpeg -ss 3.2 -t 1.9 -i videoplayback.mp4 -vf \ fps=15,scale=240:-1:flags=lanczos,palettegen palette.png




this is my code



var child_process = require('child_process')

function recordVideo() {

var spawn = child_process.spawn;

var args = [
 '-y', 
 '-ss', '3.2',
 '-t', '1.9', 
 '-i', '../getback/bin/videos/videoplayback.mp4', 
 '-vf', ' \\ ', 
 'fps=', '15', 
 'scale=', '320:-1', 
 'flags=','lanczos,palettegen palette.png', 
];



var ffmpeg = spawn('ffmpeg', args);

ffmpeg.stdout.on('data', function (data) {
 console.log(data);
});

ffmpeg.stderr.on('data', function (data) {
 console.log('grep stderr: ' + data);
});

ffmpeg.on('close', (code) => {
 console.log('child process exited with code ' + code);
}); 
};
recordVideo();




what is this error ?
I think.. 'fps=', '15', In the following code 
 '=' options a problem.



I am still learning English.
I'm sorry if it was hard to understand.
