如何在程序中设置水槽垫的属性,例如:
sin_00::outWidth=1280 sin_00::outHeight=720 in this way pipeline was run using gst-launch-0.10 .....
并设置此属性,我使用gst_pad_set_property()
了 API,但它不工作,它显示以下错误:
3_video_temp.c: In function 'main':
3_video_temp.c:551: warning: implicit declaration of function 'gst_pad_set_property'
/tmp/cc2zDbzt.o: In function `main':
/home/project/compWorkspace/Edubeam/3_video_temp.c:551: undefined reference to `gst_pad_set_property'
collect2: ld returned 1 exit status
make: *** [all] Error 1
请告诉如何尽快设置该值。
