  1. Hello everybody! How can I create access point with nmtui ? I spent some time playing with nmtui, and finally my nanopi got address something like 10.42.0.1. But it doesn't look normal, I can't create default gateway like 192.168.0.1 So, I couldn't see my hotspot from another device( android phone or other pc ) Maybe somebody resolved this problem?

    HW H.265 And H.264 Codec On H3

    Hello everybody! I use NanoPi Neo Air with Allwinner H3 I've installed cedrus264 encoder and tried to use it for webcam streaming with ffmpeg. I used htop to control cpu load and found, that ffmpeg uses too much memory! Is it normal for hardware encoding? oron@nanopiair:~/FFmpeg-Cedrus-master$ sudo ffmpeg -f v4l2 -video_size 640x480 -i /dev/video0 -pix_fmt nv12 -r 25 -c:v cedrus264 -f mpegts udp://192.168.10.236:1234 ffmpeg version 2.3.git Copyright (c) 2000-2014 the FFmpeg developers built on Feb 9 2017 11:10:38 with gcc 5.4.0 (Ubuntu/Linaro 5.4.0-6ubuntu1~16.04.4) 20160609 configuration: --prefix=/usr --enable-nonfree --enable-gpl --enable-version3 --enable-vdpau --enable-libx264 --enable-libmp3lame --enable-libpulse --enable-libv4l2 libavutil 54. 6.100 / 54. 6.100 libavcodec 56. 0.101 / 56. 0.101 libavformat 56. 2.100 / 56. 2.100 libavdevice 56. 0.100 / 56. 0.100 libavfilter 5. 0.102 / 5. 0.102 libswscale 3. 0.100 / 3. 0.100 libswresample 1. 1.100 / 1. 1.100 libpostproc 53. 0.100 / 53. 0.100 Input #0, video4linux2,v4l2, from '/dev/video0': Duration: N/A, start: 7107.486161, bitrate: 147456 kb/s Stream #0:0: Video: rawvideo (YUY2 / 0x32595559), yuyv422, 640x480, 147456 kb/s, 30 fps, 30 tbr, 1000k tbn, 1000k tbc [VDPAU SUNXI] VE version 0x1680 opened.
