I think It shouldn't be remotely as disruptive as 3.0, but we'll see.

@ilovezfs FYI: It’s announced now.

[zshbleaker]

Noticed version 4.0 is not updated yet and came here to check if there's a PR. Wish it could be merged soon.

@zmwangx there are build failures for gifski, mgba, opencv@2, openimageio, and qcli.

[ilovezfs]

gifski reported here meh/rust-ffmpeg#112 and here ImageOptim/gifski#38

[ilovezfs]

mgba is already fixed, so we can update it #26914

[ilovezfs]

opencv was fixed in opencv/opencv#10011 but it was not backported to opencv@2 (the 2.4 branch). I've commented here: opencv/opencv#10011 (comment)

[ilovezfs]

openimageio reported here AcademySoftwareFoundation/OpenImageIO#1923

[ilovezfs]

qcli was fixed in HEAD (bavc/qctools@e83d7ad) but there's no release with the fix yet.

I've requested a release in bavc/qctools#538.
However, there's an unrelated build failure on OS X 10.11 case-sensitive file systems bavc/qctools#539

[ilovezfs]

Expecting qcli to be the sole failure, which isn't sufficient reason to block this upgrade or to add a versioned ffmpeg@3 formula.

[ilovezfs]

also bumping mpv to 0.28.2 as long as we're here

[ilovezfs]

@BrewTestBot test this please

Sorry I didn't notice this before it got merged (need to add this to my email filters). I have compilation errors in some formulae in a 3rd-party tap. If there was an ffmpeg@3 formula, I'd try using that now, but since there's not, I'll just try to fix the compilation errors when I get a chance tomorrow.
