enum PixelFormat

Pixel format. Notes:

PIX_FMT_RGBA32 is handled in an endian-specific manner. A RGBA color is put together as: (A << 24) | (R << 16) | (G << 8) | B This is stored as BGRA on little endian CPU architectures and ARGB on big endian CPUs.

When the pixel format is palettized RGB (PIX_FMT_PAL8), the palettized image data is stored in AVFrame.data[0]. The palette is transported in AVFrame.data[1] and, is 1024 bytes long (256 4-byte entries) and is formatted the same as in PIX_FMT_RGBA32 described above (i.e., it is also endian-specific). Note also that the individual RGB palette components stored in AVFrame.data[1] should be in the range 0..255. This is important as many custom PAL8 video codecs that were designed to run on the IBM VGA graphics adapter use 6-bit palette components.

Enumerator:
