Silverlight MediaElement requires many H.264 frames to render one image -


i working on silverlight application implements custom mediastreamsource feeding mediaelement elementary h.264 nal units. stream starts off key frame, noticed on average takes 20 frames render 1 image. have gop size set 8 on h.264 encoder. video coming security camera , being viewed in live stream application.

the main issue induces decent amount of latency between when events happen in real life , when image rendered. small latency expected, turns out 3 seconds receiving first frame until first image rendered. shouldn't first key frame theoretically contain enough information decode image? testing have sample silverlight application loads captured h.264 stream file , internally buffers entire file, way once mediastreamsource opens, consumes ~20 frames , renders image virtually no latency.

any microsoft / silverlight / h.264 experts care elaborate on why might possibly happening?

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
