Frame rows pointers

Functions
uint8_t **	lqt_gavl_rows_create (quicktime_t *file, int track)
	Creeate a row pointer array.
void	lqt_gavl_rows_destroy (uint8_t **rows)
	Free rows array.

Detailed Description

Video frames in libquicktime and gavl are compatible for planar formats. For packed formats however, we need an additional array for storing the rows. We could allocate and free them dynamically, causing a lot of overhead. Therefore, we supply 2 functions for creating and freeing the row pointers so they can be reused.
