Yes we too ... lol but thanks for your effort. I'm confident that sooner or later it will be added. You forgot to mention what the performance is while streaming 4K content to a mobile device. That makes more sense using your nas for this usage compared to offline convert HEVC / 4K / h265 content to FullHD or so. For that usecase I have a i7 8700K running macOS (hackintosh) with Davinci Resolve and RX Vega64. Nothing beats that speed. I was really interested in the streaming usage. I have some 4K content but in most cases I can't view it because my wifi is not capable to stream that speed sustained to a mobile device. If the Nas can transcode 4K to FullHD I don't have to convert movies anymore. According to the Synology documentation the 916+ and the 918+ are capable doing this.  

Quality set to auto, on my ios in the same local network, same 4K video I tested in my previous post play 2-3s, freeze 2-3s, play 2-3s, freeze 2-3s.... can't be compared to the performance of SW transcoding

I've tried:

• all official versions of the J3455-ITX BIOS including the newly released 1.80
• flashing the J3455B-ITX and J3455-M BIOSs to the board using an external flashing device
  • the J3455B-ITX BIOS booted but for whatever reason said it was a J3355B-ITX and wouldn't get past post saying the CPU didn't match the BIOS.
  • the J3455-M BIOS also booted but the model string was incorrect
• all combinations of BIOS settings
• installing 6.2 using 3615 bootloader, then upgrading to 6.2.1 and the 918+ bootloader
• changing the GPU priority to PCIe and sticking in a PCIe video card

All of the above failed

 

It looks like the original release of the 918+ boot loader works on this board so maybe something to do with the newer i915 driver @jun put in?

 

Hi, I've spent several days on this HW transcoding problem with asrock j3455-itx motherboard. I've read all the post of this thread and some other related threads in this forum. Gotta say this might be a general problem with this motherboard. Basically, it's the i915 driver's problem and it can be searched(/dev/dri missing, i915 driver problem) from other linux forums. Finally I kind of found a way to make /dev/dri appear when install DS918+ DSM 6.2 using j3455-itx. Here is my method(But to be knoest, the performance is poor.)

 

1. My method only work on 1.03a2 + extra.lzma_v0.5(I'm not sure whether the extra.lzma is necessary but I included it when making my usb boot)

    I tested that my method won't work in 1.04b, maybe because the updated i915 driver as @jun stated.

2. When you modify the grub.cfg, changing the vid/pid/SN/MAC, also add a new arg 'i915.alpha_support=1' in the line 'set comon_args_918 = xxx', so it looks like:

 

set common_args_918='syno_hdd_powerup_seq=1 HddHotplug=0 syno_hw_version=DS918+ vender_format_version=2 console=ttyS0,115200n8 withefi elevator=elevator quiet syno_hdd_detect=0 syno_port_thaw=1 i915.alpha_support=1'

 

Install the system(I never tried migratiion) and then the /dev/dri appears and HW transcoding works fine in video station if you also have real SN/MAC. (But the performance is quite poor. I've a 35 min 4K h264 movie. For offling hw transcoding to medium quality, it says about 3 hours to finish. But SW transcoding saied 1hr to finish....sign...)

 

Another thing: DSM 6.2 seems quite slow than DSM 6.1. When I tried in install DSM 6.2, after the screen said 'find.synology.com', it took 5min for DS assistant to find my nas, and 10 min to finish install the DSM. Then the machine reboot, another 6 min before DS assistant finds the ip of my nas.  While for installing DSM 6.1, normally it only took 2 min to finish each step.

 

Besides that, in 6.2, my package center seems different from the others. Because I only got the category 'all' in the left panel,  while from the picture I browsed from the internet, there should be categories like 'recommended', 'back up', 'utility'....

 

Last but not least, shutdown is not working for my 6.2. I have to use the shutdown command in command line to turn off my nas.

 

At first I thought this motherborad would be perfect for dsm 6.2 and ds918+ since its specification is quite close to the genuine one. But now I stayed at DS916+ and DS6.1.7.
 

 

[J3455-ITX new BIOS finally released]

These versions of bios is on-line several days ago. But there seems to be some problem with the bios file.

My j3455-itx has bios version 1.60. When I use instant flash of the motherboard, the 1.70 doesn't show up while 1.80 shows up.

But the website clearly states one should first update the bios to 1.70 if it's original version is older than that before updating to 1.80.

So currently i still haven't update my bios.

But on the website, it says bios v1.80 updates the TXE FW version to 3.1.50.2222, which is exact my current verion(my bios version is 1.60, which is not listed on the website of asrock).
