is it possbile .mp4 to support pcm files like .wav and .aiff using -c:a copy?

Hi! F3D maintainer here!

We just released F3D 4.0.0, fast and minimalist 3D viewer. Obviously free and open source (and not vibecoded).

One of the key new feature is ffmpeg compatibility with the possibility to output animated 3d data directly into a video file from the terminal.

f3d animated_file.glb --output-video=- --resolution=600,600 | ffmpeg -i - out.mp4

Let us know what you think!
