[x264-devel] half & half (BugMaster)

[mm1201 at mail.ustc.edu.cn]

I find the plane[] and i_stride[] is automatically set in x264_picture_alloc,and it is finally sovled by noting "fmt.pix.filed = V4L2_FIELD_INTERLACED",but there are two other questions:
       1.When I use "ultrafast" and "zerolatency" in x264_param_default_preset,it takes 10s to process 100 frames which is 320*240,even longer 800*480
       2.So far the image is made of left part and right part,there is a clear "line" between them and the left part is between 1/3 and 1/4 of the whole width
       thanks.
