FT602 UVC configuration, color space stuck at GREY
« on: September 14, 2020, 02:03:59 PM »

Hi,
  I am using FT602 eval board UMFT602A together with Altera development board.  The UVC example design works and I can see scrolling color bars on my PC.  I am learning how to send other types of video and if I got it wrong, AMCAP will just give me a blank screen.
  While trying to send other color formats over this setup, I changed FT602 UVC configuration color space to FCC GREY using FTDI's FT602 configuration tool.  AMCAP is unable to decode this stream and unlike other forms of error, it actually pops out a dialog box and report that it unable to render video preview stream, no combination of intermediate filter can be found to make the connection.
  So I reverted to the example design and changed FT602 UVC configuration back to FCC_YUY2.  However, AMCAP continues to report the same error as previously.  I check the properties of the video device and its color space is GREY.
  I have tried to changed it back to YUY2 many times, power cycled, rebooted PC and re-install FTDI drivers, nothing works.

  Pls advice how I can configure color space back to YUY2.

Hi,
  I would like to add:

  When I change color space from GREY to YUY2 using FT602 config tools, the tool reported the value is now YUY2.  However, when I use AMCAP to check properties of video stream, it report as GREY.  And it should actually be GREY because AMCAP continues to reject the stream.  I also used other players like VideoLan and DirectCap and they would not playback the stream if it is GREY.

Hi,
  I solved it by copying config from another FT602.  Working now.
