<DIV style="FONT-SIZE: 11pt; FONT-FAMILY: Calibri,sans-serif">Thx dude I figured it out. D sample didnt had the if statement where audio stream was beeng checked and that was it. Really silly of me.<BR>Is there a way to get fixed number of sampels frm ffmpeg. The default I am getting decoded are 1024bytes of chunk which forms 1536sampels. I traversed 3times and got 4608sampels data.. But I need to decide 19200bytes ie. 4800sampels, so I am short of 192sampels. Is there a way to get those 192 sampels</DIV></DIV>
