struct ast_frame* prev

Next/Prev for linking stand alone frames Definition at line 84 of file frame.h. Referenced by ast_frfree().

int samples

Number of 8khz samples in this frame Definition at line 72 of file frame.h. Referenced by ast_frdup(), ast_frisolate(), ast_rtp_read(), ast_smoother_feed(), and ast_translate().

char* src

Optional source of frame for debugging Definition at line 78 of file frame.h. Referenced by ast_frdup(), ast_frfree(), ast_frisolate(), and ast_rtp_read().
