Testing h264Dec rev.2.00

We are in the process of testing the h264dec rev.2.00. To run the test we need to build a test app that can display a video clip downloaded into dm6437 eval board. I am using CCS 3.3.

As a test template, I  used testAppDecoder.pjt which comes with h264dec distro (on my computer it is in "D:\dvsdk_2_00\dm6446_h264dec_2_00_002_production\packages\ti\sdo\codecs\h264dec\app\Client\Build\"). The yuv file display template can be found in dm6437_evm_vpbe_st_sample.pjt ("D:\dvsdk_2_00\pspdrivers_1_10_03\packages\ti\sdo\pspdrivers\system\dm6437\bios\evmDM6437\video\sample\build\vpbe\").

 It looks like a simple project but again there are problems in properly configuring the project since I can not find references describing compiler switches and some options used in building these two projects:

  1. Where can I find descriptions of "-d"_DAVINCI" -d"TIMER_ON" -d"SELF_TESTXX" -d"_RTS_MODE" -d"FMO_DEV"" 
  2. Where can I find descriptions of "-d"CHIP_DM6437=1" -d"_TMS320C6X" -d"DM6437_SOC_BUILD" -d"BIOS_BUILD""
  3. How to integrate these options?

Again, both programs are short and conceptually simple. However, options used in their build are not readily available in CCS3 help or in Wiki. I must have overlooked some obvious references. Any advice where can I find them?

Thanks for help,

Ja

    Hi Jacek,

     

    To address your specific question, pre-processor options are primarily very application code specific except for couple of them like CHIP_DM6437 that is used by PSP library to identify it is for DM6437 device. Most of these pre-processor options would be used to do certain tasks using #ifdef under application code. Some of these options are just carried over from previous test application examples and may no longer be needed. 

    If you look at the vid_encdec.pjt file under dvsdk_1_11/examples/video_encdec/evmDM6437 directory, they have integrated video algorithm with PSP algorithm and using following pre-processor options. I would suggest using this project file as a reference as it is much simpler to work with and easy to test  

    CHIP_DM6437;_NTSC;DM6437_SOC_BUILD;_DEBUG

    Regards,

    Prateek,

    thanks for a reply.

    We used the psp project as a template - few warnings were generated but  project worked. Its a pity that the switches were not documented.

    Regards,

    Jacek
