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.
Error reinitializing filters!
Failed to inject frame into filter network: Invalid argument
Error while processing the decoded data for stream #0:0
Ideally, loudnorm should call a resampler internally, but for now,
this is what we can do.
Thanks,
