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

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 ?

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 :
