Hi everyone!
If you want to create your project based on a VCU library or modify it, then perhaps my repository will be useful to you.
Getting Started
This repository contains example how to build library and app for an easy start debugging with it.
-[vcu-ctrl-sw](https://github.com/Xilinx/vcu-ctrl-sw) - Official Xilinx repositories vcu-ctrl-sw
-[vcu-omx-il](https://github.com/Xilinx/vcu-omx-il) - Official Xilinx repositories vcu-omx-il
Prerequisites
- Windows 10
- Xilinx SDK 2018.3
- [UltraZed-EV Starter Kit](http://zedboard.org/product/ultrazed-ev-starter-kit)
Set up workspace
- clone https://github.com/mollex/workspace_uz7ev_vcu_20183
- open as workspace with Xilinx SDK 2018.3
- import projects
- set off Build Automatically
Menu: Project -> Build Automatically off
Import projects
right click on Project Explorer -> Import -> General -> Existings Project Into Workspace -> Browse -> Finish
Build
Workspace consists of:
- vcu-ctrl-sw-xilinx-v2018-3 - main library for control vcu (build first)
- vcu-ctrl-lib-app - library for application (build second)
- vcu-ctrl-encoder - encoder application
- vcu-ctrl-decoder - decoder application
- vcu-omx-il-xilinx-v2018-3 - omx library for control vcu (build first)
- vcu-omx-encoder - omx encoder application
- vcu-omx-decoder - omx decoder application
Prepare board
Images were taken by the R. Jason Moss blog post (https://www.element14.com/community/community/designcenter/zedboardcommunity/ultrazed/ultrazed-ev/blog/2019/07/09/ultrazed-ev-io-carrier-card-vcu-design-example-v20183)
Source 1
- clone repository avnet-uzev-ports
- copy files from *avnet-uzev-ports/rdf0428-uz7ev-vcu-trd-2018-3/images/vcu_uz7ev_cc/* to *SD/* card
Source 2
- download bins from dropbox https://www.dropbox.com/sh/5t0dag4momczk0j/AADh7vHkb0LU07Et-9y4ecYha?dl=0
- copy files from *dropbox/images/* to *SD/* card
- load linux *root:root*
- connect to ethernet
- set correct IP Address
- prepare and connect WinSCP.exe by SFTP for copying files to target
Testing
Test vcu-ctrl-encoder
- copy vcu-ctrl-encoder/Debug/vcu-ctrl-encoder_debug.elf to /home
- copy /images/drop.yuv to /home
- copy /images/vcu_encode_h264.cfg to /home
- copy /images/vcu_encode_h265.cfg* to /home
$ cd /home
$ chmod +x ./vcu-ctrl-encoder_debug.elf
$ ./vcu-ctrl-encoder_debug.elf -cfg vcu_encode_h264.cfg
$ ./vcu-ctrl-encoder_debug.elf -cfg vcu_encode_h265.cfg
In folder /home will appear two files drop_vcuenc.h264 and drop_vcuenc.h265 files.
Copy both to Host and play with VLC media Player.
Test vcu-ctrl-decoder
- copy vcu-ctrl-decoder/Debug/vcu-ctrl-decoder_debug.elf to /home
$ cd /home
$ chmod +x ./vcu-ctrl-decoder_debug.elf
$ ./vcu-ctrl-decoder_debug.elf -avc -in drop_vcuenc.h264 -out drop_dec264.yuv
$ ./vcu-ctrl-decoder_debug.elf -hevc -in drop_vcuenc.h265 -out drop_dec265.yuv
In folder /home will appear two files drop_dec264.yuv and drop_dec265.yuv files.
Copy both to Host and play with YUV Player.
Test vcu-omx-encoder
- copy /vcu-omx-encoder/Debug/vcu-omx-encoder_debug.elf to /home
- copy /images/drop.yuv to /home
$ cd /home
$ chmod +x ./vcu-omx-encoder_debug.elf
$ ./vcu-omx-encoder_debug.elf drop.yuv --width 256 --height 240 --framerate 25 --avc --out drop_omxenc.h264
$ ./vcu-omx-encoder_debug.elf drop.yuv --width 256 --height 240 --framerate 25 --hevc --out drop_omxenc.h265
In folder /home will appear two files drop_omxenc.h264 and drop_omxenc.h265 files.
Copy both to Host and play with VLC media Player.
Test vcu-omx-decoder
- copy /vcu-omx-decoder/Debug/vcu-omx-decoder_debug.elf to /home
$ cd /home
$ chmod +x ./vcu-omx-decoder_debug.elf
$ ./vcu-omx-decoder_debug.elf drop_omxenc.h264 -avc -o drop_omx264.yuv
$ ./vcu-omx-decoder_debug.elf drop_omxenc.h265 -hevc -o drop_omx265.yuv
In folder /home will appear two files drop_omx264.yuv and drop_omx265.yuv files.
Copy both to Host and play with YUV Player.
Test v4l2_capture_raw
Current hardware bitstream for UltraZed-EV does not include any capture port by that reason I have prepared virtual video source module vivid.ko. (use images from Source 2)
- copy dropbox/module/vivid.ko to /home card
- copy v4l2_capture_raw/Debug/v4l2_capture_raw.elf to /home
$ cd /home
$ chmod +x ./v4l2_capture_raw.elf.elf
$ insmod vivid.ko
$ v4l2-ctl --list-devices `
vivid (platform:vivid-000):
/dev/video
/dev/video1
/dev/radio0
/dev/radio1
/dev/vbi0
/dev/vbi1
/dev/swradio0
$ ./v4l2_capture_raw.elf -o -m -f -c 10
Files will appear in the folder */home*. Copy to host and open with YUV viewer.
Settings of files: YUV420 planar NV12 1280*720
Test drmdemo
Connect monitor to DP UltraZed-EV.
- copy *drmdemo/Debug/drmdemo_debug.elf* to */home* card
```$ cd /home ```
```$ chmod +x ./drmdemo_debug.elf ```
```$ ./drmdemo_debug.elf ```
wait ~10 sec, default path display device /dev/dri/card0
Test drmkmsdemo
Connect monitor to DP UltraZed-EV.
- copy *drmkmsdemo/Debug/drmkmsdemo_debug.elf* to */home* card
```$ cd /home ```
```$ chmod +x ./drmkmsdemo_debug.elf ```
```$ ./drmkmsdemo_debug.elf /dev/dri/card0 ```
