Hi,
just wondered if this is a known problem, if I take an Open EXR with a
data window != display window:
exrheader /tmp/exr_test.0001.exr
/tmp/exr_test.0001.exr:
file format version: 2, flags 0x0
channels (type chlist):
B, 16-bit floating-point, sampling 1 1
G, 16-bit floating-point, sampling 1 1
R, 16-bit floating-point, sampling 1 1
compression (type compression): b44a
dataWindow (type box2i): (873 318) - (1174 625)
displayWindow (type box2i): (0 0) - (1919 1079)
lineOrder (type lineOrder): increasing y
nuke/full_layer_names (type int): 0
nuke/node_hash (type string): "39e58529e216c6ab"
nuke/version (type string): "10.0v5"
pixelAspectRatio (type float): 1
screenWindowCenter (type v2f): (0 0)
screenWindowWidth (type float): 1
type (type string): "scanlineimage"
version (type int): 1
and I try encode it to a movie file
ffmpeg -y -loglevel debug -apply_trc linear -i /tmp/exr_test.%04d.exr
-c:v libx264 /tmp/test.mov
I end up with a full frame of black, changing EXR compression type
(none, zip 1, PIZ, etc) or data type (16 bit/32 bit) does not make a
difference, nor does switching to mp4 output container, or using mjpeg
as an codec.
If I use a file where data window and display window are the same I
get the correct output.
Thanks
Kevin
