字节队列操作
- 看一看front
- circlebuf_peek_front(&stream->dbr_frames, &front, sizeof(front));
- 删掉 front
circlebuf_pop_front(&stream->dbr_frames, NULL, sizeof(front));- 尾部插入
- circlebuf_push_back(&stream->dbr_frames, back, sizeof(*back));
码率单位是 KB /s
- K 是1000
- B 是8个字节
stream->dbr_est_bitrate =
(dur >= MIN_ESTIMATE_DURATION_MS)
