Member Function Documentation

char * MP4::Box::asBox ( )
inherited

Returns a copy of the data pointer.

char* MP4::Box::asBox ( )
inherited
uint64_t MP4::Box::boxedSize ( )
inherited

Returns the total boxed size of this box, including the header.

uint64_t MP4::Box::boxedSize ( )
inherited
void MP4::Box::clear ( )
inherited

Makes this box managed if it wasn't already, resetting the internal storage to 8 bytes (the minimum).

If this box wasn't managed, the original data is left intact - otherwise it is free'd. If it was somehow impossible to allocate 8 bytes (should never happen), this will cause segfaults later.

void MP4::Box::clear ( )
inherited
Box & MP4::Box::getBox ( size_t  index)
protectedinherited

Gets a reference to the box at the given index.

Do not store or copy this reference, for there will be raptors. Will attempt to resize if out of range. Returns an 8-byte error box if resizing failed.

Box& MP4::Box::getBox ( size_t  index)
protectedinherited
size_t MP4::Box::getBoxLen ( size_t  index)
protectedinherited

Returns the size of the box at the given position.

Returns undefined values if there is no box at the given position. Returns 0 if out of range.
