[FFmpeg-devel] Need help on bug#3302 - Cannot draw opaque text on transparent frame

[Andrey Utkin]

Dear core developers related to this functionality (lavfi/drawutils).
I'd like to have this issue https://trac.ffmpeg.org/ticket/3302 fixed
in next couple of days, for particular application. Exactly, what i
need to do is fading in/out text overlays. Of course this issue has
alternative ways to solve, e.g. make drawtext filter actually to
implement fading by by-frame evaluation of text alpha value. Currently
i suppose to work on the latter as it seems easier, but still i am
interested in the solution for original issue. I am ready to work on
the code, but i am disoriented in existing routines and need guidance.
