  • Allwinner V5 Cameras

    Here's a sensor/processor combo I haven't seen before. Anyone gotten your hands on these yet?

    - Allwinner V5 / IMX 317
    - Real 4K @ 30FPS with EIS
    - Possibly 4K60 no EIS
    - Touch screen
    - Possibly metal body (looks similar to SJ7 Star)
    - Under $100 USD

    Colour me skeptical, but I won't believe it until I get the one I just ordered next week.

    Depstech 4K/60 Action Camera - https://www.amazon.com/gp/aw/d/B07FF5W7G1

    This seems to be the generic/unbranded version. 70 USD cost per piece. I imagine we will be seeing many more of these pop up on Amazon soon around $99 - $150. http://actioncamera.diytrade.com/sdp...ion_Camer.html

    Menu is screenshots from a YT video, sorry for poor quality/res. YouTube video. https://youtu.be/ob9yYaUkzOc

    Here's another one for $140. Identical specs to the above cam although it is much closer design to the generic.

    Initial Impressions of this camera:

    Positive
    • Decently well built
    • Responsive touch screen without lag
    • Surprisingly adequate video quality in daylight
    • Audio quality is reasonable
    • User interface is straightforward (different from the pics of other cam above!)
    Negative
    • Some issues with video + EIS @ 4K resolutions
    • No LED lights whatsoever on the fronts, top, bottom or sides
    • 4K 60 with EIS is only 3200 x 1800 px
    • EIS is very basic, not the best (but far from the worst)

    First samples from this camera, I had about 10 min to film around before it became SUPER stormy.

    https://drive.google.com/open?id=1Ag...mlKIHom_35-Pmk

    Here's a preview with a couple side-by-side grabs from the 8SE. As you can see, not bad for detail on the Allwinner cam. But I do think that when you move things are more blurry. We'll have to test more in proper sunlight instead of the dark stormy light. But nonetheless, it looks rather promising, and that is probably the first time I have said that about an Allwinner...

    Note: screen grabs taken from 4K 30 video EIS OFF.


    4K 60 FPS (real 4K but only real 30 FPS) no EIS

      "Real 4K @ 30FPS with EIS"
      Not possible with this sensor. Its resolution is 3840x2160 - no extra pixels for EIS. So 4K30 video with EIS on is interpolated.

        Is there an HDMI out port? Could you please check if ADB over USB is working?

        When I plug it into the computer it shows up as "ADB Interface" in device manager. There is HDMI out but I do not have a cable to test with it.

        4K 60 w/ EIS = 3200 x 1800 px on this cam, so it is not interpolated, just not full res...

        Thanks! Seems like the ADB driver already installed in your system. Could you please run 'adb shell ls -l /dev/block/' from command line? Maybe we can get a fw backup just like with V3 cams.

      • Yes this cam does show up as ADB in device manager, but I have not tested to see if I can pull data from it

          Please share the files if you'll manage to get those /dev/block/mtdblocks.

            OK, I'll admit I am a bit over my head here. Do I just run that command on CMD? When I try it gives me an error - "'adb' is not recognized as an internal or external command, operable program or batch file." Normally I could just use your script to back up and it worked easy peasy.

            I tried to run your script for the V3 cams for shits and giggles and this is what happened:

            Backing up firmware files...

            * daemon not running. starting it now on port 5037 *
            * daemon started successfully *

            Block 2 copied.

            dd: can't open '/dev/block/mtdblock5': No such file or directory

            /mnt/extsd/backup/: 1 file pulled. 0 files skipped.
            All blocks downloaded.

            The system cannot find the file specified.



            Under "Backup" on the SD card it is just empty.

              adb.exe should be located at the same folder with the backup script.

              Run 'adb shell' and 'ls -l /dev/block/' to see if those files are there.

              Then download files with 'adb pull /dev/block/mtdblockX mtdblockX' where X = 0 - ...

              Dreki - download and install this "minimal adb" v1.4.3. Run the install exe as Administrator. https://androidfilehost.com/?fid=746010030569952951
              Install into default directory folder "C:\Program Files (x86)\Minimal ADB and Fastboot"

              Open Administrator command prompt or Administrator Powershell and do these commands
              Code:
              cd "C:\Program Files (x86)\Minimal ADB and Fastboot"
              adb shell
              ls -l /dev/block/
              exit
              .
              and tell us what you see. or a screenshot would be great too. we want to see mtdblock1 mtdblock2 mtdblock3 (etc) 🤓

            Alright done that, what do you make of it?

            I still try do do the adb pull/ /dev/block/mtdblock0 etc but it says that folder is not found...

              thanks. hm those are UNIX style soft links pointing to mtdblocks. so I suppose the mtdblocks are probably not in the /dev/block folder. and oops. maybe an auto color feature is enabled for the ' ls ' command, so we see extra characters for ANSI color sequences (if i'm correct). so try to do some more adb commands and the ' ls ' command twice. once for /dev and again for /dev/block please
              Code:
              cd "C:\Program Files (x86)\Minimal ADB and Fastboot"
              adb root
              adb remount
              adb shell
              ls --color=never -l /dev
              ls --color=never -l /dev/block
              exit

              awesome possum! thanks! for more shits 'n giggles, try this modified backup script. first use 'backup.cmd' and if that don't work try 'backup2.cmd'

            Aha, sneaky. So this cam isn't really 60FPS. It seems to be some sort of variable frame rate. Mediainfo reads is as 59.96 FPS, and going into MPC-HC I could only count 28 - 40 frames in one second. Crazy! It seems like 1080p60 is similar, I only counted 45 frames in a second. That's super sneaky, because who actually counts frames (aside from us)?

            Anyways, it looks like the first backup.cmd had some success. I think it also tries to copy MMCBLK0, then it gives a "file too large" error. But it seems to have produced it anyways? And it did not make a full_image.fex file. The archive is a whopping 1.85GB. I copied all the files it gave me whether they're relevant or not.

            7Z is on google drive with the image samples. Link here.

              Thanx for sharing!

              Your video samples have the following specs:
              4k60 no EIS - 3840x2160, 59.94 fps, 32 Mbps bitrate, 120-frame keyframe interval
              4k60 EIS - 3200x1800, 29,97 fps, 64 Mbps, 30 frames
              4k30 no EIS - 3840x2160, 29.97 fps, 64 Mbps, 30 frames
              1080p60 EIS - 1920x1080, 59.94 fps, 52 Mbps, 60 frames

              cool! but I could guess that the sdcard in the camera was formatted as FAT32, and thus 4GB file size is the limit. can the camera use an sdcard formatted as exFAT ?

              anyways, so i modified the 'backup.cmd' script to get and compress (on-the-fly) the "mmcblk0" data and hopefully the compressed mmcblk0 data will finish out as something under 4GB. give it a try plz - http://pc.cd/mBq7

              OK so this time it still complained the file was too big (because the cam formats 64GB to format FAT32), but I did get everything including the full_image.fex on the PC side of things. Check it out, it's on the link in the main post.

              Also a little observation, this camera tends to "HDR THE SH*T" out of things as I observed when filming facing into the sun, will post some samples in a day or two haha

            So here is my video review of the cam; the most recent firmware export attempt is in the previous post on Google Drive. I am pretty happy with the performance overall, despite the cam not being real 4k 60FPS. Colour is vibrant and the video has a good amount of detail. Audio quality is pretty high. The EIS could be better (I think the lens mapping is a bit incorrect at the edges of the frame), and the cam lacks indication LEDS on the top, sides and front.

            Exporting 4K60 video with Corel Videostudio was a pain in the butt because it kept giving me "Video Frame Does Not Exist" errors. I had to convert them with other software and then export them.

            Anyways, check out the review, let me know what you think.
