[FFmpeg-devel] [PATCH] [RFC] PNG: decode textual data

The attached patch implements decoding of textual data inside PNG images.

It is mostly useless right now because there is no API to return the data to
the user: the metadata API would be the preferred way, but it is in
libavformat and this not usable from libavcodec.

A possible solution is:

1. move metadata.* from libavformat to libavcore... ahem... libavutil;

2. add an AVMetadata structure to AVFrame.

Any advice?
