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!
