2. How to flash

Refer to /home/xstrive/hisi/documentation/burn.txt in the virtual machine

3. About resolution

3.1 4K video capture

Run hdmi, hdmi_92 and sample_vio in the virtual machine directory (/home/xstrive/hisi/Hi3531D_SDK_V1.0.3.0/4k) in sequence.
For example: ./hdmi &
    ./hdmi_92 &
    ./sample_vio 0

3.2 1080p video capture

Run hdmi, hdmi_92 and sample_vio in the virtual machine directory (/home/xstrive/hisi/Hi3531D_SDK_V1.0.3.0/1080p) in sequence.
For example: ./hdmi &
    ./hdmi_92 &
    ./sample_vio 0

Corresponding source code modifications

1080P

/home/xstrive/hisi/Hi3531D_SDK_V1.0.3.0/mpp/sample/common/sample_comm_vi.c  line 664, uncomment

/home/xstrive/hisi/Hi3531D_SDK_V1.0.3.0/hdmi_enc/it6801/src/drv/it680x.c  line 849, define as 6 for 1080P

Audio capture

Download audio.zip
You will get three files:
Makefile.param
sample_audio.c
sample_comm_audio.c
Put Makefile.param in /home/xstrive/hisi/Hi3531D_SDK_V1.0.3.0/mpp/sample/
Put sample_audio.c in /home/xstrive/hisi/Hi3531D_SDK_V1.0.3.0/mpp/sample/audio
Put sample_comm_audio.c in /home/xstrive/hisi/Hi3531D_SDK_V1.0.3.0/mpp/sample/common
Then
cd /home/xstrive/hisi/Hi3531D_SDK_V1.0.3.0/mpp/sample/audio
make clean
make
Finally, run sample_audio on the board and select 4. The program starts capturing audio through it6801 and then outputs audio through HDMI.

Decoding network streams

1. Download the two source packages below

live555_3531d.tar.gz
vdec_rtsp.tar.gz

2. Extract vdec_rtsp.tar.gz into the virtual machine directory /home/xstrive/hisi/Hi3531D_SDK_V1.0.3.0/mpp/sample

Then cd /home/xstrive/hisi/Hi3531D_SDK_V1.0.3.0/mpp/sample/vdec/rtsp_decode
make
The resulting xstrive program decodes network streams in real time. For details, refer to the source code at /home/xstrive/hisi/Hi3531D_SDK_V1.0.3.0/mpp/sample/vdec/rtsp_decode/decode.cpp
