[FFmpeg-devel] [RFC][PATCH] metadata name

[Baptiste Coudurier]

Hi guys,

This patch addresses issue #1501. Names are distinct.
I use "composer" to match id3v2 name already used to simplify 
application usage, though I'm not totally convinced since movies do not 
usually contain composer, and I'm not sure the most common usage of 
libavformat is for music.

Then, I noticed that using "author" for songs might not be adequate. 
Many software seems to be using "artist", especially iTunes which is the 
reference for .m4a at least, id3.org mentions "lead performer" for TPE1.

I suggest we start listing all the metadata exported somewhere (any 
suggestion ?), and mention which demuxer exports it. What do you think ?

Also I notice that mp3 demuxer now exports "native" tags, did we settle 
on this practice ? If so I will convert the mov demuxer.

It would be nice to write the adopted practice somewhere also. I believe 
metadata should be documented very well to be used correctly.

Comments very welcome.
