objective c - How to convert CVPixelBufferGetBaseAddress call to Swift? -


maybe i'm first person doing in swift there seems nothing on net using &/inout uint8_t in swift. translate please? relationship bitwise?

objective-c

uint8_t *buf=(uint8_t *) cvpixelbuffergetbaseaddress(cvimgref);

swift attempt

let inout buf:uint8_t = here cvpixelbuffergetbaseaddress(cvimgref)

cvpixelbuffergetbaseaddress() returns unsafemutablepointer<void>, can converted uint8 pointer via

let buf = unsafemutablepointer<uint8>(cvpixelbuffergetbaseaddress(pixelbuffer))

update swift 3 (xcode 8):

if let baseaddress = cvpixelbuffergetbaseaddress(pixelbuffer) {     let buf = baseaddress.assumingmemorybound(to: uint8.self)     // `buf` `unsafemutablepointer<uint8>` } else {     // `baseaddress` `nil` }

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
