I tried it on windows and it doesn't work. Is it possible that it's included only on macos/linux version?

Did you get the Windows 64-bit static dated build? I see it in there.

# Unknown bitstream filter prores_metadata

(Asked by: username_0 on 2018-11-27)

When I type the following `ffmpeg` command:

```
ffmpeg -i input.mov -c:v prores -profile:v 3 -c:a pcm\_s16le -bsf:v prores\_metadata=bt709 output.mov

I have the following error:

`Unknown bitstream filter prores_metadata`

However this bitstream filter is documented here: <https://ffmpeg.org/ffmpeg-bitstream-filters.html#prores_005fmetadata>

My `ffmpeg` version is 4.1 downloaded from *Homebrew* on *macOS 10.13*.

Any idea what is going wrong?
