So I've made inroads into allwinner v3 chipsets. There is 0 documentation on the allwinner and people speculate it can't do over 1080P, etc, etc Yet many people are ending up with fake 4k cameras that are more software crippled than anything. This was done on Q3H (allwinner + Sony IMX sensor maybe) 8/20 Small Test video: https://sendvid.com/ucnobyqc Some more samples: https://www.mediafire.com/folder/o5ncedg5ut39l/Samples Partition structure: cat /proc/mtd dev: size erasesize name mtd0: 00040000 00010000 "uboot" -bootloader mtd1: 002c0000 00010000 "boot" -kernel + initrc mtd2: 00630000 00010000 "system" -config files (squashfs) mtd3: 00200000 00010000 "cfg" - file system journals/junk mtd4: 00020000 00010000 "boot_logo" mtd5: 00020000 00010000 "shutdown_logo" mtd6: 00010000 00010000 "env" mtd7: 00010000 00010000 "private" root@camdroid:/ # the dd copies of said partitions: http://ge.tt/1MIkNnc2 You can unsqashfs "system" with squashfs here: http://domoticx.phoenixinteractive....3-i686-windows-cygwin_(lzma+lzma2+lzo+lz4).7z The camera runs camdroid OS equivalent to android 4.2.2. It is laid out like many allwinner tablets. V4L is used as a backend for video encoding and MiniGUI (http://www.minigui.org/en/) is the front end. Board/chip Pics: https://www.goprawn.com/forum/allwinner-cams/25-allwinner-v3-sony-imx179-action-cameras How I enabled ADB: Installed https://www.androidfilehost.com/?fid=24459283995302221 after camera detects an unknown "android" in webcam mode. It would not work at first but I connected with Phoenix Suite and hit enter recovery mode. After that ADB works fine. Try just the driver first. Adb has root access but some files cannot be written to because of squashfs or being restored at boot. What can be done so far: High bitrates ~50/60 megabits w/shorter GOP. Real sizes for 60fps and 120fps (IMX179s) Most ISP processing disabled (IMX179s). Sounds are fully silenced. Busybox + Other ARM code can be run or added to the image. Root+Data on externalSD in ext2 (no guide yet) What I hope for: Turn off noise reduction and sharpening and edit bit rates + image scaling. My camera came with possibly a sony IMX179 and it uses 3kx2k for 4k/2.7k/1080P. Quality is awful because of the post processing. Increase audio recorded beyond the awful 8000hz sampling rate. In testing, patches from 4pda.ru Raw Photos. The current photos aren't usable at all. Fully boot off SD card. Doesn't automount extsd. Exfat/128gb sd cards. Doesn't automount. Automatic ADB over wifi.
