Hi All, first of thanks in advance for anyone which will be able to help me out.
I'm developing a command line tool for simplifying the generation of review material , which includes a slate (a first image with notes) and then the proper clip with text, masks , fonts, luts etc.... . The final command gets generated by python (a bit a wall of text), and spawns a process which calls ffmpeg with the full command generated. Now, this seems all to be working fine under linux, but on winows, I started finding a bunch of issues. first this : https://trac.ffmpeg.org/ticket/2166 <https://www.google.com/url?q=https%3A%2F%2Ftrac.ffmpeg.org%2Fticket%2F2166&sa=D&sntz=1&usg=AFQjCNEzmfy7GKPE-4mOSGJ-ECSz3vK3jA>,which I have fixed on my side, but doesn't really look nice.... Then I have a problem with the luts, even if I format the full path to the lut correctly, it fails loading it with a strange message, which I can't undestand if it's given by the content of the lut, or the path itself. In the first case I'm wondering , could it be because the 3dl lut has been generated under linux (different endline?) and in case , is there any solution apart duplicating the luts for each os . (note the luts have been generated through ociobakelut) Here a simplified version of the command which is failing on windows: (please note, on linux works fine) Thanks. L.
