Room correction with convolution per sample rate

[digimuse]

Wow! Thanks for generating a custom ffmpeg build for the Melco.

I followed your instruction and:

• update MinimServer to minimserver-0.8.5.4, minimserver-0.8-update-128
• updated MinimStreamer to minimstreamer-0.7.12
• installed the package ffmpeg-4.1-melco-0.1 package
  

After restarting MinimServer," System:stream.converter" had the value "libext/*/ffmpeg"

I tested the system with:

Quote:stream.options:
convOut=-i /mnt/disk1/share/MinimServer/convolution/Cor1S*.wav -lavfi afir=gtype=gn

stream.transcode:
flac:wav;, dsf:wav24;352

I tested all sample rates from 16/44.1 to DSDx2. I was curious if the custom ffmpeg for the Melco was more efficient, and could handle 24/352, 24/384, DSD, or DSDx2. All sample rates up to 24/196 worked fine. Unfortunately higher sample rates still had stutter, so no change there.

I ended up with:

Quote:stream.transcode:
flac(<352):wav;

and all seems to work well with the Melco server. No convolution is performed on sample rates above 24/196 (or DSD).

Thanks very much for trying this. The custom build is subsetted in functionality (for example, the video encoders and decoders are removed) but there are no changes that would make it more efficient than a full build.
