> The pixel format shouldn't be required to be set in this muxer. I am sorry, I don't understand the word "should" in this sentence: Do you mean the webp specification is bad or that the muxer should use a different information to find out if the frames may contain transparency? Or that the ticket is invalid or that I misunderstand it? > It's generally not needed.

The webp format afaict needs the information, if the user prefers not to set it, what is the solution? > When will you learn to send properly formatted > patches (git format-patch)? Is this related to the patch? Or do you want to commit my patches (this is not necessary)?
