I still think we should do a deprecation+replacement like we do for
everything else.
You mean you want to introduce a new 64 bit member and deprecate the old
32 bit field?
E.g.
int64_t frame_num;
attribute_deprcated
int frame_number
And during the transition you want to sync the value between the 64bit
and
the 32bit ?
yes
We did make changes like int -> size_t without adding new fields in places
like AVBufferRef. See 14040a1d91.
Or AVFormatContext bit_rate sometime before.
It does however probably need an FF_API_ dance, much like in that example.
If no new field is added, and no old field is deprecated, then if the type
change is done directly before the bump, then the dance is not needed,
beacuse you'd just remove the dance at the bump.

Marton
