Convolution Help

[Alandbush]

Alternatively, if you select the Synology Package Center and browse the Community section, you will find ffmpeg version 4.1-11 available.
Installation should be straightforward from there and any subsequent updates will be alerted via Synology notifications.

My Synology Ds213j has this ffmpeg version installed in a directory that requires the following stream.converter input text value:-

/volume1/@appstore/ffmpeg/bin/ffmpeg

Either way you choose, good luck with invoking convolution.

By the way, out of interest, how are you intending to use convolution and how are you generating the convolution file?
