Streaming from USB Cam, CHIP rockz! Now with NEON support

Hi, this response is meant to motivate everyone to use graphic “intense” task on the CHIP. As I wrote above, I've used mjpg-streamer (precompiled package) on the chip to grab frames from my v4l2 USB webcam and save the frames to RAM .. well .. /dev/shm/mjpeg. This worked with the help of libjpeg-turbo which supports the NEON instructions of the CPU out of the box. I was able to run at 4fps@1280×720 with ~30% cpu utilization (i assume that the CPU contributes mostly for the USB to gpu transfer)…

Je souhaite configurer:

pc host:192.168.2.1/24  sert de passerelle
chip   :192.168.2.2/24

configurer sur le pc hote via network manager: NON NE FONCTIONNE PAS BIEN!!!!!

modifier les connexions
brancher le chip
ajout d'une interface: enp0s20u3u2 (16:7D:0F:FA:90:F5)
Ajouter: nom "Connexion Ethernet USB CHIP"
Paramètres IPV4: Adresse: 192.168.2.1/24

configurer sur le pc hote à la main

sudo ifconfig enp0s20u3u2 192.168.2.1/24 

sur CHIP

/usr/lib/klibc/bin/ipconfig  

commenter g_serial et ajouter g_ether à /etc/modules

sudo sed -i 's,g_serial,#g_serial\ng_ether,g'  /etc/modules

sudo nmcli con add type ethernet con-name usbnet ifname usb0 ip4 192.168.2.2/24 gw4 192.168.2.1
sudo nmcli con mod usbnet ipv4.dns "8.8.8.8 8.8.4.4"
sudo nmcli con up usbnet

sudo reboot sur le chip vérifier que l'interface a été créée:

ip addr

Now on the host add a suitable address to the new interface:

sudo ip addr add 192.168.2.1/24 dev enp0s20u3u2 
sudo ip link set enp0s20u3u2 up

Connexion au chip via ssh:

ssh chip@192.168.2.2

ajout de règles de routages sur le pc hote:

sudo modprobe iptable_nat
echo "1" | sudo tee /proc/sys/net/ipv4/ip_forward
sudo iptables -t nat -A POSTROUTING -o enp0s25  -j MASQUERADE

ou

sudo iptables -t nat -A POSTROUTING -o wlo0 -j MASQUERADE
