Forum Post: RE: gstreamer v4l2 1080i60 capture problem in EZSDK05 05 02 00 : Call to S_FMT failed for NV12 @ 1920x1080: Invalid argument

Hello,

Our board does not use the fbdev.So the saloopBack can not run through. At least the program can call the V4L2 API  S_FMT  and set the format.

I checked the gstreamer V4L2src  code. In the gstreamer gstv4l2object.c, it uses "field = V4L2_FIELD_SEQ_TB".

But in ezsdk ti81xxvin_main.c, the drivers always use field = V4L2_FIELD_INTERLACED.

Does  this mismatch lead to the gstreamer api S_FMT call error?

Thanks
