Detailed Description

Jitter Buffer.

Typedef Documentation

mpf_jitter_buffer_t

typedef struct mpf_jitter_buffer_t mpf_jitter_buffer_t

Opaque jitter buffer declaration

Enumeration Type Documentation

jb_result_t

enum jb_result_t

Jitter buffer write result

Enumerator
JB_OK	successful write
JB_DISCARD_NOT_ALLIGNED	discarded write (frame isn't alligned to CODEC_FRAME_TIME_BASE)
JB_DISCARD_TOO_LATE	discarded write (frame is arrived too late)
JB_DISCARD_TOO_EARLY	discarded write (frame is arrived too early, buffer is full)
