What version of Delphi?

Hello,

I confirm a lot of problems with the headers.

1 - The SLD compilator directives (IFDEF) are set to WINDOWS instead of MSWINDOWS. It leads to the messages given by KevinSUI581. 2 - Some types definition problems (UINT8 instead of Byte) 3 - Some missing array declaration in TSDL_Overlay declaration (Pixels and Pitches). 4 - A depreciated function called (linesize) where the type is expected integer instead of word. 5- a missing @ in the use of packet for some functions (like av_free_packet) ....

All these are visible when you compile ffmpeg_sample_player.

Done with Delphi 10.3.2 and the latest download of the "OpenCV" release (that includes FFMPEG)

Hello,

Tested. It works fine. Thanks

Question, why did you not include directly the bindings provided on the SDL website. They exist for Delphi and use SDL2 instead of SDL.

This is just an example for testing FFMPEG.
