ffmpeg conversion for CRT

Open sd2cv opened this issue 2 years ago • 0 comments

RGB-Pi OS adjusts the CRT refresh rate based on the game rate, as the video file is 23.976023 fps this does not work and a 15khz NTSC tv is unable to display ~24hz.

For someone to convert the m2v and ogg file properly for rgbpi os NTSC the user must use the below ffmpeg command. The output is exactly the same time rate example lair.ogv 30mins 44seconds

.\ffmpeg -i cliff.m2v -i cliff.ogg -codec:v libtheora -qscale:v 7 -codec:a libvorbis -r 29.970 -qscale:a 5 -pix_fmt yuv420p cliff.ogv
