Gonzalo Garramuno	e0bb74a140	exr: Add a gamma flag to exr loader to avoid banding This is needed to avoid banding artifacts when gammaing the picture. Currently, if done with a video filter, the process is done on uints instead of full float. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	10 years ago

Gonzalo Garramuno	3d20260157	avcodec/exr: read layers EXR files have, like tiffs, multiple channels and layers. I have a patch for exr.c that allows you to select the layer you want to process thru a -layer flag. It is not bulletproof but works for all layers that have 3 channels in them (normals, motion vectors, etc). The calling convention for ffmpeg is: ffmpeg -layer Diffuse -i myexr.%d.exr test.mov Here's an exr image with multiple layers: http://www.datafilehost.com/d/e45d9a1c Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
