Linux/TMS320DM369: Latency expectations using either IPNC or GStreamer

Part Number: TMS320DM369
Other Parts Discussed in Thread: DM385

Tool/software: Linux

I’m developing an application using a DM369 and DM385 to pass compressed images over a wireless Ethernet interface.  I need to minimize the latency of:

  1. Demosaicing the Bayer camera image on the DM369.
  2. Compressing the image using jpeg.
  3. Passing the compressed image over WiFi. 
  4. Decompressing the image on the DM385 using jpeg.
  5. Displaying the image using HDMI.                                                                                                                                

A couple of questions:

  1. Does TI recommend IPNC over GStreamer?  Is IPNC going to be supported for a while?  Is there GStreamer support on a “new” Linux kernel, using TI coprocessor code?
  2. I have a fairly new distribution of the DVSDK for the DM385 (ipnc_rdk-3.9.1).  Is there a new IPNC distribution for the DM369?

    Hi Larry,

    Does TI recommend IPNC over GStreamer?  Is IPNC going to be supported for a while?  Is there GStreamer support on a “new” Linux kernel, using TI coprocessor code?

    • Yes TI recommend IPNC. Yes , IPNC will be supported for a while.There is no support for Gstreamer on new Linux kernel image for platform DM38x and DM36x.

    I have a fairly new distribution of the DVSDK for the DM385 (ipnc_rdk-3.9.1).  Is there a new IPNC distribution for the DM369?

    • As of now there is no such new IPNC distribution for DM36x.The latest IPNC distribution for DM36x is IPNC_RDK_V5.1.0.For further information about the new release please contact your local TI FAE.

    Regards,

    Thanks, Anuj.

    Can you help me find my TI FAE?  I work in Cranston RI, just south of Providence RI, about an hour south of Boston MA.

    Thanks,

    Larry
