 Hello all:

    I am using DM368 ipnc (ver 2.6), now I want to test the decoder function,

but it will display some error such as follow

1. if I use # ./moduletest.out alg_vidDec

 CLK Hz,

 DDR   Hz =  340000000
 VPSS  Hz =  340000000

can anyone give me some advise how to correct it?

Now I want to add my own decoder(h.264->yuv420) on ipnc, but I can't get any resource about this.

    Hi,

    Which version of the decoder are you using? Can you post the decoder configuration parameters  ?

    You can get the latest decoder from the location

    Hi, Thanks for your reply,

    My decoder version is "H264DEC.version.02.00.00.05" that provided by appro DM368 ipnc.

    Sorry, I am a newbie for this, I don't know how to get decoder configuration parameters.

    Can your give me some hint?

    If the previous responses don't resolve your issue...

    Unfortunately, there isn't really anything in your CE_DEBUG output that points to any particular problem. More information about the seg fault is needed. The only way I know how to get more information is to run your application under control of gdb, the Linux debugger. If you can do so, when the application seg faults you can issue the 'bt' command (backtrace) to find out exactly where in the program the seg fault occurred. You might not have gdb on your Linux system, but instead might have gdbserver. This is a little more difficult to use than straight gdb, but in a pinch it comes in handy.

    Regards,

    Hi,

    The alg_vidDec.c file in IPNC system might not be updated with the latest changes needed to use H264 Dec 2.00.xx.xx. The reason is that IPNC inherently does not need video decode operation and hence the source file might not be in sync with the codec library.

    I am attaching alg_vidDec.c (framework/alg/src) which has been used with the same decoder version and is tested/verified. You can refer to this file and update the alg_vidDec.c that exist in your codebase.

    Regards,

    Anshuman

    PS: Please mark this post as verified, if you think it has answered your question. Thanks.

    Hi,

     

    I am facing issues in generating the moduletest executable.

    As suggested in manual make and make exe doesn't run properly and when

    i am cross compiling main.c in moduletest folder by issuing the following command:

    /opt/mv_pro_5.0/montavista/pro/devkit/arm/v5t_le/bin/arm_v5t_le-gcc main.c

    i am getting following errors:

    main.c:(.text+0x594): undefined reference to `DRV_eepromTestMain'
    main.c:(.text+0x5b8): undefined reference to `gOSA_printfLock

     

    Thanks and Regards,

    Mayank
