ffmpeg.js build is missing defined format

Question

I'm attempting to encode files using pcm_f32le with the f32le format. I've defined both the encoder and format within the makefile present in the cloned ffmpeg.js repository:

WEBM_MUXERS = webm ogg null data f32le
WEBM_ENCODERS = libvpx_vp8 libopus pcm_f32le

If I print out available codecs using the -codecs option, I can see pcm_f32le as an available encoder. However, the -formats option is missing the f32le format. If I attempt to use the format to encode, ffmpeg complains that it isn't a available format.

I'm sure I'm missing something trivial. Any help?

Answer 1

Turns out the pcm_f32le is also used as the format.
