<DIV><FONT size=2> I find in our libary that
the preferred frame size of PCM audio sourc is close to 20
ms both from file or audio input device.</FONT></DIV>
<DIV><FONT size=2>I want to know why we choose 20ms size and dont choose bigger
size?</FONT></DIV>
<DIV><FONT size=2> in my program, i need capture audio
data from a particular audio input device through parallel port and stream it.
The program is that for the particular of the device, i only can get
the audio data from paralle port wait for every 500ms time, one time get
500ms data. so i want to set the frame size of 500ms
in doGetNextFrame() function. </FONT></DIV>
<DIV><FONT size=2> I think streaming 500ms size per
frame also can be fluencily. but the test fact is that the realplayer
can recive and play fluencily but the quicktime player couldnt play
the audio fluencily. What is the reason? </FONT> <FONT
size=2>is the cache buffer in quicktime player too small to receive a 500ms size
data one time? </FONT></DIV>
<DIV><FONT size=2> need your help!
