I see no document updates, commit messages, or deprecation warnings
that would:
* Explain what and why this is happening - this should at the very
least be in the commit message(s), if not a doc somewhere. IRC or
pevious ML threads are not sufficient.
I'll mention it in a commit message. The idea is to properly propagate
and make available the global side data in AVCodecContext, and no longer
have to inject it in the first packet. This way global and frame
specific side data is separate, and there's no need to copy and inject
entries in several different places.
The new struct allows the simple use of a single set of helpers that
don't depend on the context containing the side data.
* Warn users they need to update their code to not use stream side data (?).
Will my code just silently change behavior if it was using stream
side data? I legitimately do not know due to the above.
How so? This, like any other deprecated field, remains working as it
always did until it's removed. The downstream users will see the
deprecation warning during compilation, and the doxy for the field
mentions the direct replacement. It's standard procedure.
I'll add a @deprecated comment to the doxy of
av_format_inject_global_side_data() to mention the aforementioned objective.
* Any useful doxy for API users or any example aside from function args and
very basic struct info.
The helper functions are basically the same as the packet ones, and the
stream ones I'm deprecating. add(), new(), get(), etc. Example usage as
usual is in ffmpeg.c, but i think the doxy does a good job explaining
what they do.
I make no comment on the usefulness or utility of the change, but it is these
sorts of things that make downstream API users experiences a little worse.
