    GUID for RGB8?


      I have created a project for my 8 bit input with raw8 pix format

      i have edited my guid and frame size for the input, but i am getting error in media players like ffplay and vlc.


      i have referenced microsoft docs and got guid




              0xAF,0x0B,0xA7,0x70,            /*GUID for RGB8  "e436eb7a-524f-11ce-9f53-0020af0ba770" */

      I have also edited the frame rate that is 25 fps

      whatelse to change? please review my code thanks.

          All generally available Media Players does not support RAW format (8 or 10 or 12 bit). You need some custom application to do this job.


          If your firmware is correct except the RAW 8, you would have seen some color in the media players. Please state that what  is the error that the media players showing.


          Can you please confirm whether the data flow is fine with your firmware? Which device you are using here FX3 or CX3?

              Please see this thread. May be it will help you to understand the issue:




              Try to re-install the "v4l2" and then try again. Also list down the devices as mentioned in the above thread and look for the FX3 in the list.


              Thanks & Regards
