I have a problem with Greek subtitle font size when I map a subtitle file into a video in ffmpeg.
I ran below code:
When I play it in VLC, it gives very small subtitle size.
Then I tried to increase subtitle fontsize but no luck.
Also tried this one but failed again:
As default fontsize in ffmpeg is 16, this time I increased fontsize from 16 to 30 in vf_drawtext.c file, then I reconfigured ffmpeg and replaced new ffmpeg binary file but nothing changed.
PS: I tested below code as -vf is invalid when -c:v copy is selected..
Could you please explain how I may do this?
Thanks
Boris
