Description

I want export video with subtitle, then this ass subtitle need some font, like ttf,ttc,otf In ffmpeg cli like

ffmpeg.exe -i INPUT -c copy -attach INPUT_FONT -metadata:s:t:0 mimetype=application/x-truetype-font

can you provide an example file? what is INPUT? your ffmpeg command doesn't work because it doesn't have any output

Ok, I think I understand, you want to do the opposite of -dump_attachment (as can be seen here):

instead of extracting attachments from a file, you want to attach them to a file. (-attach) I think it's a useful feature request.

yeh, video add subtitle, some of them dependent on the specified font. If not exist, subtitle will still work, but it's not well in expected.
