android - MediaCodec and 24 bit PCM -


i using mediacodec decode audio, when load file 24-bit samples, have no way of knowing has occurred. since application assuming 16-bit samples, fails.

when print mediaformat, see

{mime=audio/raw, durationus=239000000, bits-format=6, channel-count=2, channel-mask=0, sample-rate=96000}

i assume "bits-format" hint, key not declared in api, , not emitted when output format changes. get

{mime=audio/raw, what=1869968451, channel-count=2, channel-mask=0, sample-rate=96000}

(by way "what" key? notice if interpret 4charcode, "outc"... flag output format?)

so best recourse here? if feed bytebuffer straight audiotrack plays static of course (assuming pcm 16).

if know value, can convert myself! understand other questions cannot dictate output format either.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
