/** |
|
* Pixel format. Notes: |
|
* |
|
* PIX_FMT_RGB32 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_RGB32 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. |
