Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
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. -

swscale/aarch64 : add vscale specializations
13 août 2022, par Swinney, Jonathanswscale/aarch64 : add vscale specializations
This commit adds new code paths for vscale when filterSize is 2, 4, or
8. By using specialized code with unrolling to match the filterSize we
can improve performance.On AWS c7g (Graviton 3, Neoverse V1) instances :

Error : ffmpeg exited with code 1 on AWS Lambda
16 juin 2022, par Hassnain AlviI am using fluent-ffmpeg nodejs package to run ffmpeg for audio conversion on AWS Lambda. I am using this FFmpeg layer for lambda.
Here is my code


const bitrate64 = ffmpeg("file.mp3").audioBitrate('64k');
 bitrate64.outputOptions([
 '-preset slow',
 '-g 48',
 "-map", "0:0",
 '-hls_time 6',
 '-master_pl_name master.m3u8',
 '-hls_segment_filename 64k/fileSequence%d.ts'
 ])
 .output('./64k/prog_index.m3u8')
 .on('progress', function(progress) {
 console.log('Processing 64k bitrate: ' + progress.percent + '% done')
 }) 
 .on('end', function(err, stdout, stderr) {
 console.log('Finished processing 64k bitrate!')
 })
 .run() 


after running it via AWS lambda I get following error message


ERROR Uncaught Exception 
{
 "errorType": "Error",
 "errorMessage": "ffmpeg exited with code 1: Conversion failed!\n",
 "stack": [
 "Error: ffmpeg exited with code 1: Conversion failed!",
 "",
 " at ChildProcess.<anonymous> (/var/task/node_modules/fluent-ffmpeg/lib/processor.js:182:22)",

 " at ChildProcess.EventEmitter.emit (domain.js:448:20)",
 " at Process.ChildProcess._handle.onexit (internal/child_process.js:248:12)"
 ]
}
</anonymous>

I don't get any more info so I am not sure what's going on. Can anyone tell me what's wrong here and how can I enable more detailed logs ?

ffmpeg remote url not working in lambda function
9 septembre 2024, par KomalI have created lambda function to trim video.


I run this command :


/opt/bin/ffmpeg -protocol_whitelist file,http,https,tcp,tls -i 'https://source-bucket.s3.amazonaws.com/1.mp4' -ss 5 -t 10 -loglevel 48 -y -avoid_negative_ts 1 -acodec copy /tmp/output.mp4


It gives following output :

So, its not going beyond this : 'Opening 'https://source-bucket.s3.amazonaws.com/1.mp4' ; for reading\n'


And after this, it immediately gets out. Need suggestions, where its going wrong. Same command working fine on local computer.


I tried cloudfront and signed url as well, as mentioned in this post : How to read remote video on Amazon S3 using ffmpeg. But it doesnt work with url. Only working when downloaded into tmp folder.


Following is the final log, which you can see is no timeout. It actually finish function execution within 2-3 seconds. I have timeout set for 15 mins to the function which is maximum :
