| 55 | * Pixel format. Notes: | |
| 56 | * | |
| 57 | * PIX_FMT_RGB32 is handled in an endian-specific manner. A RGBA | |
| 58 | * color is put together as: | |
| 59 | * (A << 24) | (R << 16) | (G << 8) | B | |
| 60 | * This is stored as BGRA on little endian CPU architectures and ARGB on | |
| 61 | * big endian CPUs. | |
| 62 | * | |
| 63 | * When the pixel format is palettized RGB (PIX_FMT_PAL8), the palettized | |
| 64 | * image data is stored in AVFrame.data[0]. The palette is transported in | |
| 65 | * AVFrame.data[1] and, is 1024 bytes long (256 4-byte entries) and is | |
| 66 | * formatted the same as in PIX_FMT_RGB32 described above (i.e., it is | |
| 67 | * also endian-specific). Note also that the individual RGB palette | |
| 68 | * components stored in AVFrame.data[1] should be in the range 0..255. | |
| 69 | * This is important as many custom PAL8 video codecs that were designed | |
| 70 | * to run on the IBM VGA graphics adapter use 6-bit palette components. | |
