how to hardcoded subtitle .srt in .mp4 with ffmpeg windows???

[Baldrick]

You can't hardcode just with ffmpeg. Maybe mencoder instead.

[gugaoforums]

whatermark?

drawtext?

I cant do this too

help me please!

[El Heggunte]

IIRC, it's possible to "pipe" the output from MPlayer into ffmpeg.

Not sure how fast (or slow) that will be, though.

I am searching for just that type of solution, for W32 however... if anyone finds the proper code to pipe from mplayer, we would appreciate seeing it.
