#今天ijk支持边播边缓存了吗#

想做边播边缓存和修改seek逻辑（seek后不重新缓冲）
目前找到了些方法，不知道哪是切入点
边播边缓存的：
// ff_ffplay.c
static void video_image_display2(FFPlayer *ffp);
static int read_thread(void *arg);
// ijkio.c
static int ijkio_read(URLContext *h, unsigned char *buf, int size);
// ijkiocache.c
static int ijkio_cache_read(IjkURLContext *h, unsigned char *buf, int size);

seek的：
// ff_ffplay.c
static void stream_seek(VideoState *is, int64_t pos, int64_t rel, int seek_by_bytes);
int ffp_seek_to_l(FFPlayer *ffp, long msec);
// ijkio.c
static int64_t ijkio_seek(URLContext *h, int64_t offset, int whence);
// ijkplayer.c
int ijkmp_seek_to_l(IjkMediaPlayer *mp, long msec);

我该修改哪个方法呢？ 请求大佬指教，谢谢了啊

Start by tracing the listed entry points in ff_ffplay.c, ijkio.c, ijkiocache.c, and ijkplayer.c to understand the existing read, cache, and seek flow. Reproduce the current playback and seek behavior before choosing a modification point. Done means streaming can cache while playing and seeking does not trigger unnecessary rebuffering.
