          Bought one of these:
          https://www.banggood.com/4K-60fps-Wi...r_warehouse=CN

          It is advertised as 4k60fps, but it seems the highest bitrate is achieved in 4k30fps so I guess that's its native resolution.
          I manages to get a backup of the firmware with a slightly modified V3(s) backup script. The naming of the mtdblocks is different.

          Firmware:
          https://j2n.nl/v316/backup.tgz

          Script:
          https://j2n.nl/v316/backup.sh

          /proc/cpuinfo
          https://j2n.nl/v316/cpu.txt

          The device info in the menu displays:
          - Product Model: V316
          - Software Version: V3.0
          - Update Time: 2019-05-28 10:28:46

            Dav: noticed the noise too. It also seems to record far to high brightness in overcast conditions like in the test footage. I tried this afternoon on Ev -3 and that seems to improve the situation a bit.

            nutsey: the following AE metering options are available: average, center, spot and matrix. I tried them and did not experience much of an improvement in overcast shots.

            petesimon: never noticed your very first comment until now, sorry. Here is a link to the output of the commands you mentioned in your post.

            https://j2n.nl/v316/output.txt

            The whole show is running from two binaries: sdvcam and webapp. They seem to be using minigui indeed. The webapp binary reference to language resources from minigui. The startup script /etc/init.d/S01app does some copying and md5 summing of the sdvcam binary to the sd card. I don not really understand what it is doing there...


            There is a real chatty application log in /var/log/log/sdvcam.INFO going on. I uploaded one where I switch on the camera, record a movie for 3 seconds and then connect the USB to the PC.

            thanks for sharing information. be sure to always click the arrow to expand and see all comments

            in your text logs, i see HDMI drivers and HDMI plugout events. Could the LCD be connected to the main board by HDMI cabling?

            I saw the ANMR0011.mp4 file name. Is the naming convention "ANMR0001", "ANMR0002", and so on?
            - i found similar video names in google - https://youtu.be/iVtoisUk49k

            the "adb shell ls -l /sys/class/drm/" command didn't work. let's try to list as many hardware devices as we can, 'n later we could probe into some devices. please do these commands when the camera is on and connected via USB, or via your tty console setup, and share the 'devices.txt' file.
            Code:
            adb kill-server
            adb root
            adb remount
            adb shell ls -lR /sys >> devices.txt
            adb shell ls -lR /dev >> devices.txt
            adb shell ls -lR /proc >> devices.txt
            Thanks!

              оно через 2.7К зачем-то прогоняется предварительно. может из-за стаба? Я для себя внешний стаб буду брать.

            The official answer from the manufacturer of the camera hdking with Soc V316. Cameras with SOC V316 have h265 codec

              the hardware can do h265, but will the firmware actually utilize this feature and actually encode video as h265 in mp4 (or mov) files?

            Last night I opened the camera up to have a look inside. There is a working console on the tx and rx pins. It just logs you in with root without password. The main application log is also printed out to the console.

            Console works on 115200 baud.

            It would be nice if we could get it to boot from sd card instead of emmc...

              The format of the H264 codec is written in the firmware. It is not possible to change the camera menu from "0" to "1"(H265). In the next firmware this will be done
              (hopefully).

              petesimon good job

                vzzbx maybe h265 is not exhibited in all modes, the size of the image. For example GoPro 6-7 not in all sizes pictures of the has codec h265 --> https://gopro.com/help/articles/block/hevc

                  I would imagine that the option would be greyed out then instead of hidden. There is an option called "distortion correction" which is greyed out in every resolution over 1080p60fps because the system is (propably) too slow to perform that tricks at higher resolutions. In the menu the option is then greyed out, but still visible. It would have been stupid to hide h265, because it is one of the selling points for crappy cameras like these. Let's not talk about the bullshit 4k 60fps recording mode...

                  This firmware version seems very immature and lacking of features. The metering modes seem to do nothing. The recordings are by default far too bright, especially on overcast days. The photo modes are a joke, 2013 era smartphone pictures.

                  Whether this is going to improve is really in the hands of the manufacturer.

                  Why buy this camera? Personally it was the cheapest (semi-) native 4k30fps option currently on the market to strap onto my miniquads so I would shed the least amount of tears when I would inevitably crash this thing thing into a tree.
                  If you insist in buying a true 4k30fps camera that does h265 encoding then buy something with an iCatch V50 chipset, much better. Still sorry I crash my Vikcam V50 into a lamppost...

                  TLDR: Sorry for the rant, this version has no h265.

                vzzbx Your camera's cheaper. nutsey Doubt that your camera has a true 4K. I want to ask you about the test chamber. It is necessary: 1-to take photos using the maximum resolution of the ruler (the school). 2 - Immediately switch to video mode and make the same video 4k30 and 4k60 file (ruler). try to put the camera down and not touch it. Stabilizer and other things off. And all this (photos and videos) to put on google drive or somewhere else. It would be good at the same time that there was a lot of light. You understand me?

                  Нет там растяжки. Тупо 4К30 пишется с дублированием каждого второго кадра. И в 4К30 там баг, кстати, есть судя по прошивке выше... оно через 2.7К зачем-то прогоняется предварительно - мыло будет то ещё...
