Can anyone help me how to use system fonts on ffmpeg Termux? Whatever I
try is only giving me DroidSansFallback. Here is another one that ffmpeg
says....
{{{
[Parsed_ass_2 @ 0xa51dd240] fontselect: ("/system/fonts/DroidSans.ttf",
400, 0) -> /system/fonts/Lohit-Punjabi.ttf, 0, Lohit-Punjabi
[Parsed_ass_2 @ 0xa51dd240] fontselect: (DroidSansChinese, 400, 0) ->
/system/fonts/Lohit-Punjabi.ttf, 0, Lohit-Punjabi
[Parsed_ass_2 @ 0xa51dd240] Glyph 0x41 not found, selecting one more font
for (DroidSansChinese, 16, 400)
[Parsed_ass_2 @ 0xa51dd240] fontselect: (DroidSansChinese, 400, 0) ->
/system/fonts/DroidSansFallback.ttf, 0, DroidSansFallback
}}}
This the last ffmpeg says...
{{{
