Hi there,
I have some D-log M video files from my DJI Mavic 2 drone that I would
like to process on my linux system in Openshot. In order to apply a 3d LUT
I use ffmpeg with the option -vf lut3d=<LUT file>. However using a default
LUT file provided by DJI results in a error. PLease help!
Summary of the bug:
How to reproduce:
{{{
% ffmpeg -i input.mp4 -vf lut3d="DLog-M+to+Rec709.cube" output.mp4
ffmpeg version 3.4.6-0ubuntu0.18.04.1
built with gcc 7 (Ubuntu 7.3.0-16ubuntu3)
}}}
The output of ffmpeg is:
[Parsed_lut3d_0 @ 0x55fd3ad23e20] 3D LUT is empty
[AVFilterGraph @ 0x55fd3ad21c20] Error initializing filter 'lut3d' with
args 'DLog-M+to+Rec709.cube'
Error reinitializing filters!
Failed to inject frame into filter network: Invalid data found when
processing input
Error while processing the decoded data for stream #0:0
Conversion failed!
I have an other LUT file (thisoneworks.cube) that does work as expected
when applied to the same video file, so I'm wondering what's going wrong
here.
