[FFmpeg-devel] Is it really this easy to thread PNG encodes?

[Ben Jackson]

I'm working on VP6A (video with alpha) so I'm doing lots of exports to
PNG stacks.  I looked into what it would take to thread the PNG encoder
(when using -f image2) and it seems utterly trivial since it's an Intra
CODEC.

The attached patch (which just sets CODEC_CAP_FRAME_THREADS / INTRA_ONLY)
seems to work, but it's almost too easy!
