dm6446 decode error with dvsdk_2_00_00_22

MRI
Expert 1130 points

I can encode the video fine, but when I try to decode it hangs. I want to output the video to s-video. I use the comand:

#./decode -v v.264 -O s-video

When do a Ctrl-C, I get the following:

Unable to handle kernel paging request at virtual address c793c014

    I double-checked the uboot settings and made some changes. I also executed the commands:

    $ make codecs clean
    $ make codecs
    $ make clean
    $ make
    $ make install

    But I'm still getting a decode error. See below:

    ----------------------------clip---------------------------------------------
    root@10:/opt/dvsdk/dm6446# ./decode -v v2.264 -s s.g711 -O s-video

    loadmodules seems to be ok. Here's the output:

    I have the same problem.Do you have solution？

    MRI,

    I just installed the software per the Getting Started Guide (GSG); I did not do a 'make codecs clean' or 'make codecs' and was able to encode, decode and encodedecode sucessfully.  I couple of things worth noting are

    1) The first few messages after 'make' (section 4.6 of GSG) tell you if you have any components missing from the installation (very important)

    2) cmem starts at 118M, (in the past, it has started at 120 M); therefore, your bootargs must reflect this.  Otherwise, you will likely get errors when trying to run ./loadmodules.sh prior to running demos. 

    these are the only two things I noticed were different from previous builds.
