[FFmpeg-devel] The patch series about premultiplied alpha

Hi.

I write this mail to the technical committee to state that since Niklas
Haas has stated intent to stop discussing on the mailing-list, I am
asking the technical committee to make a decision on the subject.

It will take me a little time, at least several hours, maybe a few days,
to properly express my arguments clearly and cross-reference them for
your convenience, but I can already give the gist of them:

- The patch series lacks transverse user documentation.

- The patch series increases the risk of data corruption due to user
  negligence and should include at least some guardrails against that.

I will develop both these points as soon as possible.

In the meantime, it should go without saying but I am afraid it needs to
be said, (1) Niklas Haas cannot be part of the decision, or even private
discussion if there is one, since he is already part of the
disagreement, and (2) the patch series cannot be pushed until the
decision is made.

Regards,
