c++ - QAudioProbe is consuming excessive memory under Windows -

-

i writing mp3 player in qt , need monitor audio levels. this, attach qaudioprobe qmediaplayer. however, when in windows, memory consumption continuously increases. after 3 hours of playing audio, player exhausts memory on machine , ceases function.

memory consumption stable under osx. stable when attaching audio probe qaudioinput.

i've tried delete , deletelater on probe not result in reduction in memory usage according task manager. there alternatives qaudioprobe? running out of ideas how around memory issue.

qmediaplayer *player = new qmediaplayer(this); player->setmedia(qurl_to_my.mp3);  qaudioprobe *probe = new qaudioprobe(this); probe->setsource(player); // memory usage stabilizes if comment line out  player->play();

update: other things have tried qaudiodecoder - unfortunately, seems have same memory leak. it's not implemented under osx. executing code in separate qthread - still leaks memory.

is possible to, in single query, sum bunch of values in 1 table, , divide count of rows in another? there common id/key in both tables... fyi, win points least info provided in question. answer it's possible...here psuedo code since i'm guessing @ tables , columns select summing / counting whynot (select id, sum(whatever) summing where_ever ) inner join (select id, count(1) counting what_ever)b on a.id = b.id question = 'vague' group a.id
