编译失败懂C言的来看看
编译失败这是返回的vo_ivtv.c: In function 'ivtv_reset':
vo_ivtv.c:79: error: storage size of 'sd' isn't known
vo_ivtv.c:80: error: storage size of 'sd1' isn't known
vo_ivtv.c:85: error: 'IVTV_IOC_STOP_DECODE' undeclared (first use in this function)
vo_ivtv.c:85: error: (Each undeclared identifier is reported only once
vo_ivtv.c:85: error: for each function it appears in.)
vo_ivtv.c:95: error: 'IVTV_IOC_START_DECODE' undeclared (first use in this function)
make[1]: *** [vo_ivtv.o] Error 1
这是原码
77 ivtv_reset (int blank_screen)
78 {
79 struct ivtv_cfg_stop_decode sd;
80 struct ivtv_cfg_start_decode sd1;
81
82 sd.hide_last = blank_screen;
83 sd.pts_stop = 0;
84
85 if (ioctl (ivtv_fd, IVTV_IOC_STOP_DECODE, &sd) < 0)
86 {
87 mp_msg (MSGT_VO, MSGL_ERR,
88 "IVTV_IOC_STOP_DECODE: %s\n", strerror (errno));
89 return 1;
90 }
91
92 sd1.gop_offset = 0;
93 sd1.muted_audio_frames = 0;
94
95 if (ioctl (ivtv_fd, IVTV_IOC_START_DECODE, &sd1) < 0)
96 {
97 mp_msg (MSGT_VO, MSGL_ERR,
98 "IVTV_IOC_START_DECODE: %s\n", strerror (errno));
99 return 1;
100 }
101
102 return 0;
103 }
有没有懂看的来看看怎么错了
