 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...


 {{{
 frame=  899 fps=1.7 q=0.0 Lsize=   25350kB time=00:00:29.97

 Thanks in advance for those who can help me!
