Description

I created a GIF from a portion of an MKV which has SRT subtitles, but the subtitles don't show up in the GIF. I thought it's supposed to burn in the subtitles. The preview shows them.

I temporarily got rid of ~/.mpv/config in case one of the options in it caused the problem, but the subtitles still didn't show up in the GIF.

I also tried to remove --sub-ass-override=yes --sub-ass-vsfilter-aspect-compat=yes --sub-auto=exact --sub-pos=100 --sub-delay=0.000000 from the encoding command. It didn't help.
