Since your input LRA is 9.4, and output LRA is 7 (default), the
filter will upsample to 192 kHz. You should resample afterwards.
Ok, whats the correct way to do that?
e.g.
ffmpeg -i input -af loudnorm=...,aresample=48000 output
This just gives me:
[Parsed_aresample_1 @ 0x7f99fb503ec0] Cannot select channel layout
for the link between filters Parsed_aresample_1 and format_out_0_1.
Share complete command and log.
$ ffmpeg -i ~/Movies/input.wmv -af
