[FFmpeg-devel] [PATCH] libavutil/dict: extend the list of convienience functions for storing different data types

[Kevin Wheatley]

Hi,

as part of adding support for non-string data types to .mov metadata,
I wondered about adding the following helper functions for storing
numeric types into an AVDictionary.

upfront I'll say I'm not 100% happy with the float32 and float64 named
variants (vs float and double) as there is no clear preference in
other areas of the code that I could see.

I'm also conscious that to provide for rewriting the .mov metadata
types, I'll need something different to store the actual types and
that might mean these functions would end up not being used at all.
