convolution with acourate fir filter

[simoncn]

For -lavfi afir to work, you need to be using FFmpeg 3.4.0 or later (see this post). What platform (NAS or computer) are you using to run MinimServer?

The convOut setting is a string containing options for the ffmpeg command. There are a lot of these options and you would need to look in the FFmpeg documentation for a list of what the options are and what they do.

I am working on some improvements to how MinimStreamer supports -lavfi afir and this support will be documented in the MinimStreamer user guide when it is available.
