Hello! When I load a movie, FFMPEG tells me which PixelFormat it uses to represent the pixel data of every frame. In which source code file of FFMPEG is defined, when to use which PixelFormat?
At the moment if I load a MPEG file, FFMPEG uses PIX_FMT_YUV420 to represent the gray scale value of every pixel in a value range between 16 and 235, which is a information loss, if the movie stores every gray scale value between 0 and 255. I would like to know, which video codec I have to use to create a MPEG file that stores its gray scale information in a value range between 0 and 255 and if FFMPEG then correctly uses the PIX_FMT_YUVJ420P (J420P instead of 420P!) pixel format.
