c# - naudio waveProvider.AddSamples causing a crash -

- 

private unsafe static void audiostreamcallback(intptr buff, int32 size)  {     byte[] samples = new byte[size];     marshal.copy(buff, samples, 0, size);      waveprovider.addsamples(samples, 0, size);     bytes_played += size; }

in above code, buff returned native dll written in c. logging, have printed number of bytes added sample. based on log, getting below mentioned error after playing 2.4 mb samples.

unhandled exception: system.invalidoperationexception: buffer full @ naudio.wave.bufferedwaveprovider.addsamples(byte[] buffer, int32 offset, int32 count)

do need free buffer or make sure flush old entries before adding new samples? looked @ source code, didn't find related buffer size. missing thing.

thanks help.

bufferedwaveprovider backed fixed size circular buffer. once full throws exception (newer versions of naudio allow configure whether exception thrown or whether audio silently discarded). latest code allows set bufferduration before first call addsamples increase buffer size default of 5 seconds worth of audio.

actionscript 3 - TweenLite does not work with object -

-
i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines. ...
