Ask HN: Do you remux WebM to MP4 without re-encoding?

I built a small tool for converting WebM to MP4 without re-encoding.

It only does stream copy via FFmpeg.

• No quality loss • Very fast (seconds) • Works offline • Drag & drop • Batch support

Supports AV1 streams.

Does not support VP8/VP9/Vorbis (by design, no re-encoding).

Curious how others here handle WebM → MP4 conversion workflows.
