Default crop align for Avs+ is now (I think) True, wheareas False for Std Avs [EDIT: if not aligned via eg RoboCrop, then produces an error alert from AVS+, on return].

from Avs v2.58 Version Header 3 [the compressed help with SDK has both Version 6 (avs+) and v2.58 version 3 headers, for easy perusal],

Code:

  // generally you shouldn't use these three
  VideoFrameBuffer* GetFrameBuffer() const { return vfb; }
  int GetOffset() const { return offset; }
  int GetOffset(int plane) const { switch (plane) {case PLANAR_U: return offsetU;case PLANAR_V: return offsetV;default: return offset;}; }

For Planar, is usual to allocate single buffer, where Y plane is aligned at start of buffer, and U, and V somewhat later, GetOffset returns the offset from buffer base (methinks).

EDIT: When you swap U and V, all it probably does is swap offsets.
EDIT: Above also (I think) mirrors official standards for file based layout of raw YUV streams [with some alignment padding for offsets and also each individual raster line].
