[Quad HDMI Recorder] Image captured shifted right

PostTue Feb 23, 2021 5:43 pm

Hello,

After normal working of DeckLink Quad HDMI Recorder for a few weeks, with the last SDK and running over Debian 10, I have issue with the image captured by the device.

The image captured is shifted to the right, the las row of the image, that supposed, you should view in the rigth part of the image is the row that you see in the left part of the frame, and the rest of the image is moved to the rigth to compensate the shifting.

**Example with a simple matrix**:

Correct frame:
[1][2][3][4][5][6][7][8][9][10]
[1][2][3][4][5][6][7][8][9][10]
[1][2][3][4][5][6][7][8][9][10]
[1][2][3][4][5][6][7][8][9][10]

Corrupt frame geted:
[10][1][2][3][4][5][6][7][8][9]
[10][1][2][3][4][5][6][7][8][9]
[10][1][2][3][4][5][6][7][8][9]
[10][1][2][3][4][5][6][7][8][9]

I tried to change the HDMI interface to other ports of DeckLink Quad HDMI and the problem persists, and I am sure that the source is not the problem becouse I tried to conncet to other devices and works property. Also I used differents methods for get the image, like MediaExpress software or ffmpeg...

The only way that I know for solve this is rebooting the PC, after that works well for a couple of days. But I consider that this solution is too much invasive method for other system services.

Hello,

Thanks for the answer, I also hope have a resolution for this issue soon.

In the meanwhile, do you know any way or tool to do a hot reboot/reset/rescan of the Quad HDMI Recorder? so as not to have to reboot the PC every time this issue appears.
