Reason for write EPIPE error in my implentation ?
18 mai 2019, par Chrisl446So I currently have a small node.js express application for uploading images using sharp & thumbnails created from .mp4 videos using simple-thumbnail package/ffmpeg.
The app works perfectly when uploading an image, the file is uploaded sharp processes it, then passes it along and it ends up in my amazon s3 bucket as expected. No errors what so ever.
However, when I upload an mp4 video that I use to create and upload a thumbnail from by using simple-thumbnails genThumbnail() function, which uses ffmpeg child process, the thumbnail uploads successully to my s3 bucket, HOWEVER my app returns an EPIPE write error and NOT the url of the uploaded files url on S3.
What is causing this and how can I fix it, considering it’s pretty much working aside from the EPIPE error that is being returned ? Thanks ahead !

swscale/aarch64 : use multiply accumulate and increase vector factor to 4
17 novembre 2019, par Sebastian Popswscale/aarch64 : use multiply accumulate and increase vector factor to 4
This patch implements ff_hscale_8_to_15_neon with NEON fused multiply accumulate
and bumps the vectorization factor from 2 to 4.
The speedup is of 25% on Graviton1 A1 instances based on A-72 cpus :$ ffmpeg -nostats -f lavfi -i testsrc2=4k:d=2 -vf bench=start,scale=1024x1024,bench=stop -f null -

after : t:0.032168 avg:0.032215 max:0.033081 min:0.032146The speedup is of 39% on Graviton2 m6g instances based on Neoverse-N1 cpus :
