[FFmpeg-devel] avcodec/psd : add support for gray float (WIP)

[Martin Vignali]

Hello,

Better patch in attach (reuse the same "copy part" than uint 8bpc and 16
bpc pix fmt)

Works only after applying swscale patch in discussion :
swscale : hScale16To19 : limit shift for float(32bits) input

Can be test with :
./ffmpeg -i lena-gray_float.psd -pix_fmt gray8 res8.png
./ffmpeg -i lena-gray_float.psd res16.png
