Video processing program can only run once

Jose Lopez1
Intellectual 835 points



Hi, I am working on dm8168 EVM. My software does video capture | DSP processing | Display. 

This chain works from start to end, but has some internal issues making my program to run only once, after that it dumps some errors and make the program unavailable to run  the 2nd or n times,

How can this get fixed so the program runs smooth and can execute it as many times as wanted ?

I am using ezsdk-5_05_02_00, m3 firmware loaded +  drivers. 

I would really apreciate some help on this. -Regards

    Hello,

    Are you using gstreamer?

    Hi Margarita thanks for the reply, 

    Yes i am using gstreamer.

    I dont know if gst can be contributing to this after-run issue. The log mainly points to driver problems (syslink for example), there should be something that can clear out why this is hapenning after the program exists. I am using also Codec Engine. 

    Best Regards

    Hello,

    Could you post your bootargs? Also are you  observing syslink errors when you start the application second time?

    You could check this topic also:

    http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/717/p/245285/864506.aspx

    http://e2e.ti.com/support/embedded/linux/f/354/t/225015.aspx?pi196120=1

    Could you check the tear down of the pipe?

    Best Regards,

    Margarita

    Hi, 

    Regarding the bootargs, 

    mem=168M@0x80000000, i have reduced partition for Linux (no Linux partition 2). Also m3 firmware and DSP goes according to EZSDK Memory Map, this is true because I have other more basic demos that run smooth without syslink warnings or backtraces. 

    According to the post you copied, there was a suggestion of increasing vmalloc, it may help fixing this ones:

    Hello,

    Could you run, also:

     ./loggerSMDump.out 0x9e400000 0x100000 all

    This is avilable at /usr/share/ti/ti-uia folder in filesystem.

    Getting the assertion in ResTrack.c line 380, means you have either not deleted a MessageQ, a HeapBufMP, or failed to call Notify_unregister (or Notify_unregisterSingle).
