Summary of the bug:
Using ffmpeg build N-94300-gaf5f770113
There is an issue reading exr files generated from vray render engine that
have a single zdepth channel. However an exr files with two zdepth
channels are read without an issue. Important to note is that this error
is only caused by vray's zdepth pass, all other passes work fine.
This was not an issue in the previous build N-82143-gbf14393
How to reproduce:
Included are two exr images:
s02-01_Double_.0000.exr and s02-01_Single_.0000.exr
One exr image with a single zdepth pass and another with 2 zdepth passes.
Compressing the single exr will create a read error but compressing the
double will not. Compressing an exr image without zdepth work as well as
compressing exr image with other passes other than zdepth also works.
(s02-01_none_.0000.exr and s02-01_all_others_.0000.exr respectivly)
