android - Face detection on Samsung devices -


i use android face detection api camera.facedetectionlistener .

i have several tablets.

  • a galaxy tab gt-p5110 2 version 4.0.3 (kernel: 3.0.8-365113-user dpi dell155 @ # 1)
  • a galaxy tab gt-p5110 2 version 4.1.1 (kernel: 3.0.31-523998 se.infra @ sep-98 # 1)
  • a galaxy tab gt-p5210 3 version 4.2.2 (kernel: 3.4.34-1135839 se.infra @ s0210-10 # 1)

the detection works on first on second tab 2, turn on face detection, preview flick , detection slow.

on tab 3, listener never invoked if did not detect faces.

i tried sample : http://developer.samsung.com/android/samples/mad-hatter-face-recogition have same issues.

is there known bug on samsung devices ?

thanks

it known samsung's devices perform differently. have treat different samsung's device carefully. can use 2 steps investigate issue: 1. pass bitmap directly detection api check whether can work. 2. check preview fps. maybe have set different parameters improve camera performance.

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...

c++ - End of file on pipe magic during open -

i have c++ application in starting process(wireshark) following. if (fp == null){ fp = popen(processpath, "r"); //processpath process want start if (!fp){ throw std::invalid_argument("cannot start process"); } fprintf(fp, d_msg);//d_msg input want provide process } else if(fp != null){ fprintf(fp, d_msg); } the problem when execute c++ application, start wireshark error end of file on pipe magic during open what should avoid that? also tried using mkfifo create named pipe , execute it. used this: if (fp == null){ system("mkfifo /tmp/mine.pcap"); fp = popen("wireshark -k -i /tmp/mine.pcap", "r"); if (!fp){ dout << "cannot start wireshark"<<std::endl; throw std::invalid_argument("cannot start wireshark"); } input = fopen("/tmp/mine.pcap", "wb"); fprintf(input , d_msg); fclose(input)...
