c - libVLC can't do overlay and record video stream together -

I am using libVLC to process and record videos from an IP camera, but overlay work during recording Can not - that means I comment on the code that duplicates the stream to save a file - the overlay works but if I leave the code - the video is recorded but on the screen or Either an overlay in the file Is not used.

Using libVLC 2.06 on Windows 7 (x64). But this problem is unchanged with the 32 bit version.

Try "- sub-source = marq" In your option instead of - - SubFilter = Mark "
