Hi,

     In our board we are using decoder ADV7182 with BF561, the compressed output when played using VLC PLAYER bottom half is blurred and a black vertical bar is observed . The compressed output from H.264 BP encoder is attached. I am programming following registers of ADV7182,

 

40 0F 00 ; Exit Power Down Mode [ADV7182 writes begin]

 

40 00 00 ; INSEL, CVBS in on Ain 1

 

40 0E 80 ; ADI Required Write

40 9C 00 ; ADI Required Write

40 9C FF ; ADI Required Write

40 0E 00 ; Enter User Sub Map

 

40 03 0C ; Enable Pixel & Sync output drivers

40 04 07 ; Power-up INTRQ, HS & VS pads

40 13 00 ; Enable INTRQ output driver

 

40 17 41 ; select SH1

40 52 CD ; ADI Required Writes [ADV7182 writes finished]

 

40 1D 40 ; Enable LLC output driver.

 

Can anyone help me with this ASAP. Any other registers I need to program?  or any parameter I have to change for H.264 encoder?

 

Note: 1) Analog camera format - PAL

            2) H.264 BP encoder is used to grab the frames from ADV7182 and compress.

            3) video_codec_input.video_standard = 3, Active PAL. All other parameters for H.264 BP encoder are same as its demo code.

            4) I have tested the analog camera with BF561 EZ-kit, its working fine (compressed output is fine).

            5) The free run mode (ADV7182) output is also attached, In that also we observed same effects.
