Issues about running DM6467 decode/encode demo

Other Parts Discussed in Thread: TVP7002

Hello, I am novice at dm6467.

1.when I finished the DVSDK environment according to GSG(DM6467 Getting Started Guide), I run the demo of "decode", "encode", "encode and decode" using the remote control. I found the decode demo run normally. but when I run the "encode" demo and "encode and decode" demo, there some errors . The error information in the serial console is like this:

 

reg 00, val=2

reg 01, val=ce

......

......

reg 5a, val=0

reg 5b, val=10

tvp7002 1-005d: querystd, erorxx. val=0, val1=0

 

 

I can ensure that the camera input video is 720P60.

      

2.when I try run the decode demo with command line. I also meet issues. I typed in commands as what GSG says like below:

 

Target $ cd /opt/dvsdk/dm6467

Target $ ./loadmodules.sh

Target $ ./interface

At this point, error occurs. It says

Demo interface started at level vpif_display vpif_display: Streaming in progress   0.                                                                                                                              
                                                                                                                                                                                                               
Interface Error: Failed to create display device instance

And I typed below command to run the decode demo.

Target $ ./loadmodules.sh  

Target $ ./decode –v data/videos/davince_###_1080i_30fps.264

 

The same error happened.

Decode demo stared

vpif_display vpif_display:Streaming in progress

Error:Failed to create display device

decode:ce/Vdec2.c:117:Vdec2_process:Assertion 'Buffer_getNumBytesUsed(hInBuf.


Can anyone tell me why the error occurs and how to solve the issues?

 

Thank you very much!
