First, thanks for this very useful free open source software.
The bug found : Recently I noticed that I can’t export to gif anymore with v17.10. I tried with v17.08 (pre ffmpeg update) and it worked like a charm. Logs said that “Formats with a palette require a minimum alignment of 4” and also shows an error about using a function deprecated while trying to converting to gif which… i didn’t copy unfortunelly.
The settings to convert to gif my video was exactly the same in both tries, and only pre ffmpeg update version did it.
This issue was found on a windows 10 machine 64 bits using v17.10 for windows 64 bits.
That all depends on how MLT is built. If it using FFmpeg > 3.0 it will not work as it is a limitation of MLT that it broke with newer FFmpeg. I know as I am the MLT lead developer. At least with Shotcut builds I provide we can clearly communicate about it instead of the “it depends.” Sorry, but GIF is not just very high priority for me.
