Appro 2A frame rate settings

Hi everyone,

Currently running the Appro 2A software library on the dm365 platform, using MT9P031 senssors. I was just wondering what the default frame rate the Appro 2A library is expecting and how do we configure this setting. I was looking at the IPNC code that is provided with the Appro library, and notice that it sets the frame rate in one of its global structure to zero. Unfortunately it has no documentation on what this value means, that I can see. Any help would be most appreciated. Thanks.

    Though I do not have an answer as I have not used the Appro kit, I wanted to note that this is probably something you want to ask Appro directly as they own that software stack. Perhaps someone else in the community whom has used the Appro kit can comment further.

    The member Aew_ext_parameter.sensor_frame_rate is an indication for library to do something when frame rate is lower than real-time.

    This value range is
    {
    0,//default 30fps
    1,//15fps
    2 //5fps
    }
     
    This member is set from the web page on
     
    Stream.c (av_capture\application\ipnc\multimedia\av_server\src\stream) 
    stream_feature_setup()
    {
    case STREAM_FEATURE_M41_FRAMERATE:
    ....
    switch(input_val)
        {
         case 0:
          set_val = 0;
         break;
         case 15000:
          set_val = 1;
         break;
         case 5000:
          set_val = 2;
         break;
     
        }
    .....
    Aew_ext_parameter.sensor_frame_rate = set_val;
    break
    }
    Hope this helps..
    Regards,

    Thank you for the response. I was hoping I could set the frame rate to a higher value like 60fps, but it looks like from your explanation, APPRO may only be supporting 30, 15 and 5fps.

    Hi,

    The 2A library was tuned and tested for IPNC reference design. If you need to ensure that the support for 60fps is available or not, you can talk to Appro. They can work out something to change the library. Ofcourse, one thing to note is that the 2A library is appro's IP.
