Combining ffmpeg-normalize with ffmpeg pan filer about ffmpeg-normalize HOT 6 CLOSED

I also changed the ' ' marks to " " in the second syntax example and ran it again. That resulted in the first error again ('FL' is not recognized...)

Not on a computer right now, so I can only guess, but you're going to want to use the "pre filter" or "post filter" options instead of the "extra" option. You cannot override the entire filter chain, since that is what ffmpeg-normalize will be using for its internal processing.

Regarding the pipe symbol, you may have to escape that with a backslash, since otherwise it may be interpreted as piping the output to another command.

See here for some examples of pre filtering: https://github.com/slhck/ffmpeg-normalize/wiki/examples#filters

from ffmpeg-normalize.

For that, use the --extra-output-options option. The audio channel option in ffmpeg is not a filter, so it needs to be applied to the output file and cannot be used in the pre-filter list of filters.

That should be the same. You can downmix in ffmpeg-normalize, too.

I would recommend to downmix first just using ffmpeg, then use ffmpeg-normalize to perform normalization on the stereo file.
