不知道有没有人用过gst-launch v4l2src device=/dev/video0 ! 'video/x-raw-yuv, format=(fourcc)UYVY' ! mfw_isink disp-width=512 disp-height=384来采集摄像头的数据显示到屏幕上，我使用的时候虽然可以正常显示，但是还有一些错误信息比如
can not create threadmfw_gst_isink_setcaps:1489

VS0 created. in fmt[UYVY] mxc_sdc_fb mxc_sdc_fb.0: Should use the overlay frameb

还有
hwbuf allocator zone(614400) created
imx-ipuv3 imx-ipuv3.0: IDMAC12's EBA0 is not 8-byte aligned
imx-ipuv3 imx-ipuv3.0: IDMAC11's EBA0 is not 8-byte aligned
等等，这些大概是什么导致的呢？
有没有人有一些mfw_isink的资料可以共享一下啊，尤其是他如何实现功能的，谢谢啦 |
