Thanks a lot for this pointer. A quick question; For the .pointer function, it says " This callback is called when the PCM middle layer inquires the current hardware position on the buffer." Does the word "PCM middle layer" mean that the MMF like Helix / Gstreamer is continuously querying for hardware position on the buffer? Or does the player keep querying? I also see that this function gets called quiet a number of times. Is there a way to reduce these calls? My guess is that to reduce the number of calls to .pointer, MMF or player needs to be modified. Am I thinking right? -Harsha On Fri, May 9, 2008 at 4:26 PM, Takashi Iwai <tiwai@xxxxxxx> wrote: > At Wed, 7 May 2008 09:10:00 +0530, > Harsha priya gupta wrote: > > > > Hi, > > It would be really helpful if someone can help me understand why do we > need > > to implement .pointer and what does it need to do?
