Ganesh Ajjanagadde	2cbaa078d1	avcodec: use HAVE_THREADS header guards to silence -Wunused-function When compiled with --disable-pthreads, e.g http://fate.ffmpeg.org/report.cgi?time=20150917015044&slot=alpha-debian-qemu-gcc-4.7, a bunch of -Wunused-functions are reported due to missing header guards around threading related functions. This patch should silence such warnings. Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>	9 years ago

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.

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
