MPSoC VCU TRD 2019.1 - SDI Video Capture and SDI Display -v2 No Output

Jump to solution

Hello,

I tried to implement Zynq UltraScale+ MPSoC VCU TRD 2018.3 - SDI Video Capture and SDI Display project but it didn't work then I changed my version to 2019.1 as @kvasantr suggested in this thread. However, it didn't work neither. Also I got the blue screen in 2018.3 project but now I can't get anything.

Then I noticed there is a second version of 2019.1 project and now I am trying to implement that. At first, I decided to run default image in 2019_1 v2 project. When I run vcu_gst_app, pipeline seems like it is working but I can't see any output on my monitor.

My setup is simply like this: SDI video generator -> ZCU106 SDI In -> Encode-Decode -> ZCU SDI Out -> SDI to HDMI converter -> Monitor

Here is the terminal output of the execution.

Hello @silat14 

Does it work now?

Yes it will not work with the default modetest which is part of autostart.sh script. you will need to modify it for full HD resolution.

Thank You

Hello @silat14 

Please help me with the following questions:

1. are you getting the blue screen after booting the images?

2. What is your SDI video source?

3. What is the resolution of your Monitor?

4. Please give a try to other configurations as mentioned below:

config/
├── 4kp60
│   ├── Display
│   ├── Record
│   ├── Stream-out
│   └── Stream-in
├── 4kp30
│   ├── Display
│   ├── Record
│   ├── Stream-out
│   └── Stream-in
├── 1080p60
│   ├── Display
│   ├── Record
│   ├── Stream-out
│   └── Stream-in
└── input.cfg
Input.cfg used input as recorded file for decoding.
Input Configuration : START
Input Num : 1
Input Type : sdi
Uri : file:///media/usb/test_1.ts
Raw : FALSE
Width : 3840
Height : 2160
Exit
 
Please read the configuration file before using vcu_gst_app.
 
Thank you

Hi @kvasantr ,

1. are you getting the blue screen after booting the images?

No, I am not. My monitor isn't 4K and I didn't change autostart.sh. This is probably the reason for it.

2. What is your SDI video source?

I use Blackmagic Video Assist 4K as SDI input and my video is in 1080p60fps format.

3. What is the resolution of your Monitor?

I have a Dell U2715H Monitor, it supports up to 2K resolution. I use a SDI to HDMI converter beforehand.
