We want 720P output on imx6Q platform , but met output issue .our platform ENV:
1. kernel 4.1.15 +manual path "L3.14.52_1.1.0_GA_bt656_output_patch".
we check the ITU-R BT1120 document and progressive scan like as bellow:
and we check the function code _ipu_dc_setup_bt656_progressive in Ipu_disp.c, we found that :
when send blank video on I-frame . it send whole line (bt656_v_start_width+bt656_v_end_width) by _ipu_dc_write_tmpl(ipu, microcode_addr, BMA, loop_frame_blank_line_times, 0, 0, 0, 0, 0, 0, 0);
we can't control the bank line (L2-L1) and (L6-L5), it is different on 720P and 1080P.
Did you verify these code yet ? Kindly please give us advice or give me more information about these ,we requried question at several days ago at
