La sauvegarde automatique de canaux SPIP
1er avril 2010, parDans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...) -

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.emit (events.js:198:13)",
 " 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 ?

avformat/hls : Be more picky on extensions
16 janvier, par Michael Niedermayeravformat/hls : Be more picky on extensions
This blocks disallowed extensions from probing
It also requires all available segments to have matching extensions to the format
mpegts is treated independent of the extensionIt is recommended to set the whitelists correctly
instead of depending on extensions, but this should help a bit,
and this is easier to backportFixes : CVE-2023-6602 II. HLS Force TTY Demuxer
Fixes : CVE-2023-6602 IV. HLS XBIN Demuxer DoS AmplificationThe other parts of CVE-2023-6602 have been fixed by prior commits

swscale/aarch64 : use multiply accumulate and shift-right narrow
9 décembre 2019, par Sebastian Popswscale/aarch64 : use multiply accumulate and shift-right narrow
This patch rewrites the innermost loop of ff_yuv2planeX_8_neon to avoid zips and
horizontal adds by using fused multiply adds. The patch also uses ld1r to load
one element and replicate it across all lanes of the vector. The patch also
improves the clipping code by removing the shift right instructions and
performing the shift with the shift-right narrow instructions.I see 8% difference on an m6g instance with neoverse-n1 CPUs :
$ ffmpeg -nostats -f lavfi -i testsrc2=4k:d=2 -vf bench=start,scale=1024x1024,bench=stop -f null -
