i developed functional live streaming app on ios biggest issue right quality of service. implemented rtsp protocol on phone send sr packets , handle rr packets qos informations. need find way change bitrate settings stream session on fly in order smooth stream. currently can set own custom settings method : (avassetwriterinput *)assetwriterinputwithmediatype:(nsstring *)mediatype outputsettings:(nsdictionary *)outputsettings however, outputsettings readonly need find way deal it. @property(nonatomic, readonly) nsdictionary *outputsettings i saw livu app can it, there should way :) so possible change bitrate of avcapturesession without restarting , configuring new avcaptureinput? saw can change defined presets want configure bitrate more accuracy.

i want checked if set time less calender(mobile device)time. shows alarms set , if set time not more 1.5 hr shows "ruko ruko" message. if both conditions false go else condition. not gave me expected results. here code: gregoriancalendar mcalender=new gregoriancalendar(); mcalender.set(2013, 7, 17, 13, 0); if(mcalender.gettimeinmillis()<=cal.gettimeinmillis()){ toast.maketext(getbasecontext(), "sets ", toast.length_short).show(); } else if(mcalender.gettimeinmillis()+5400000<=cal.gettimeinmillis()){ toast.maketext(mcontext, "ruko ruko", toast.length_short).show(); } else{ toast.maketext(getbasecontext(), "time not gone ", toast.length_short).show(); } the problem mcalender.gettimeinmillis() checked first. example, when alarm set 5:30, @ 4:30 first part true already, else if section entirely skipped. got reverse order , :) if(mcalender.gettimeinmillis()+5400000<=cal.gettimeinmillis()){ //if sti...

i'm new programming in c# in unity , there problems when moving in z-axis. problem continue move when let go of button. however, when move in x-axis fine, letting go of button stop player. code below: using unityengine; using system.collections; public class player : monobehaviour { public vector3 motion = new vector3(); private charactercontroller controller; private bool onground; private float xrot, yrot; public static float x_rotation = 0; public static float y_rotation = 0; private const float lookspeed = 2.0f; public void start() { controller = getcomponent<charactercontroller>(); } public void fixedupdate() { if(screen.lockcursor) { vector3 impulse = new vector3(); if(input.getkey(keycode.w)) impulse.z+=1; if(input.getkey(keycode.a)) impulse.x-=1; if(input.getkey(keycode.s)) impulse.z-=1; if(input.getkey(keycode.d)) impulse.x+=1; if(impulse.sqrmagnitude > 0) { motion += quaternion.euler(...

accelerated c++, exercise 14.5 involves reimplementing split function (which turns text input vector of strings). 1 must use store input in std::string - class ( str ) & use split function return vec<str> , vec being std::vector - container. str class manages custom pointer ( ptr ) underlying vec<char> data . the str class provides constructor str(i,j) , in str.h below, constructs ptr underlying vec problem arises when try create substrings calling str(i,j) i've detailed in code the issues arise. here whittled-down version of str class (can post more code if needed): str.h #include "ptr.h" #include "vec.h" class str { friend std::istream& operator>>(std::istream&, str&); public: // define iterators typedef char* iterator; typedef char* const_iterator; iterator begin() { return data->begin(); } const_iterator begin() const { return data->begin(); } iterator e...

i trying user public photos (friend's friend). when browse facebook see them, can't access them via api. neither select created, link, caption, images, like_info photo owner in (select uid user username = "...") or object_id in (select uid user username = "kaja.szuminska") or object_id in (select object_id photo_tag subject in (select uid user username = "...")) order like_info desc limit 0, 100 nor .../albums nor .../photos nor .../photos/uploaded works. any ideas? to access photos (public or not) need permission. it's possible access photos (using user_photos permission) or friends' photos (using friends_photos permission). if want scrape public photos, can checking user's public feed. i.e. making api call to: https://graph.facebook.com/{user_id}/feed , filter through entries see if photos posted.

from textfile(range.txt), range:1:2:3:4:5:6....:n: there's list of result, need extract digit 1 2 3 last digit, last digit may varies so read in file, extract out delimiter , push vector. ifstream myfile; myfile.open("range.txt"); istringstream range(temp); getline(range, line,':'); test.push_back(line); how capture value? have , capture 1 digit. i have , capture 1 digit you need use loop :- while (getline(range, line, ':')) test.push_back(line); later using vector can process integers only.

if create document in mongodb using create method. ua.create({mystringfield: 'mystringdata'}, function(err, myua){ callback(err,myua); }); later want search new string in database , use method. ua.findone({mystringfield: 'mystringdatanew'}, function(err, myua){ callback(err,myua); }); notice set original mystringfield data 'mystringdata' , searching 'mystringdatanew'. findone() method returns document containing 'mystringdata' result of query. how query exact matches strings in mongodb? many help. i'm pretty getting confused. findone call exact, case-sensitive match. partial matches or case-insensitive need use regexp instance not basic string. suggestion make simple test case separate app, , suspicion db not behaving way think is.
