[vlc-devel] [PATCH] avcodec: map the more transfer functions to VLC equivalents

[Stève Lhomme]

Uh, wrong title and doesn't compile...

BTW, AVCOL_TRC_GAMMA22 is described as "ITU-R BT470M / ITU-R BT1700
625 PAL & SECAM". We map it to SRGB. Does that mean
TRANSFER_FUNC_BT470_M and TRANSFER_FUNC_SRGB are actually the same ?
