30KM 1080p 60fps 150ms - SIYI HM30 Full HD Digital Video Link Telemetry Radio System

@ktrussell Thanks for the info. I installed the program.
But this file can’t be openend. This error message apears:
“Can’t fiinde Demuxer for file siyi_001.264”

It works with a normal .mp4 File.

With the Program PotPlayer the SIYI Video .264 is visible on the PC monitor.
And with the Program Wondershare Filmora I can record the screen and save as .mp4 File.
Not verry ingenious but helps until they find the right solution.
I own 10 different Cams/FPV Systems/Drones, all records .mp4 Files.

I wonder if other open source solutions could “containerize” the raw H264 data (which may actually be H265…that’s the format that’s streamed, despite the 264 moniker in the URL). Try Handbrake, OpenShot, or ShotCut?

Please do not bother yourself with buying a new smartphone or tablet. There will be an update about the USB connection very soon.

Thanks for your suggestion. We are already working on it. I’ll post as soon as .mp4 direct output is updated.

Hi Mohammad
We suggest that you can try the 24km mode. The 40km mode is only suggested for certain scenes which is clearly written in the manual.

It’s true that 64GB SD card does not work properly with R1 Recording Camera. We are working on this and will try to update asap.

@SIYI Great you are back Frank, I missed you.
Of course, the cam is a new thing, I can wait for .mp4.
By the way. The Airunit arrived and works now (bench test only, due to bad weather).
I seems the short inverse Power and/or the missing antennas where the reason for the failure.

Hi Frank, I am going to be attempting a 36km mission, and already purchased 2 17db (Maple Wireless) antennas for the mission from your store. ArxangelRC on Youtube confirmed his HM30 works on 40km mode but mine will not maintain connection. Regardless of which antenna I use.

Please help with 2 questions.

  1. Will I be able to complete my mission in 24km mode, even thought I will be 36km out?
  2. How can I flash the “VideoVer” and “SkyVideoVer” to both be 0.2.2 since you can see they are mismatched (SkyVideoVer is 0.2.1). Maybe this is what is preventing 40km mode from working?

Either way, I would like to get 40km mode working just for sanity during testing. Unless 24km and 40km mode both use the same output power?

@lorbass can you check for me if 40km mode works on your HM30?

40km connects, but with interrupts of about 2 seconds(blue LED of ground unit).
The video is to see, the Telemetrie and TX was not tested.
5, 8 and 24 km works normally. Just bench test inside, with stick antennas.

Yeah mine goes red (no connection whatsoever to radio) and only connects for 1 second every so often. I’m hoping it can be fixed by setting the video versions same on airunit and ground unit. Awaiting Frank’s response.

Thank you Frank,

Getting frustrated on not getting it working!

Hope you had a good New Years

I’ve sent multiple emails to support@siyi.biz and gotten no replies for weeks on end. Really hoping i can get some help with matching the skyvideover and videover.

Hey guys- When dealing with Chinese companies it is really important to remember that the end of January to the 2nd week of February- the entire country goes on Holiday. During this period you can expect no responses as they are all gone. Also-because of being gone for so long there will be a huge backlog of stuff to get done and typically support is lower priority than making money. Give them until March to get back to full speed. =)

@SIYI

Hi,

I have an issue with the HM30, it just stopped working one day.

Right now on the air unit, the FPV status indicator is fixed red or yellow, link status indicator is off and RF status indicator is blinking red 3 times then pause then blinking 3 times

I had a similar issue. But I guess it was my fault. One time I made a inverse polarity of the power supply
for the air unit. After that it worked again. But later forgott to assemble one antenne stick.
Here the connection process after that with left top the Battery indication, left down the Airunit and
right the Ground Unit.

Ordered another Airunit, and it works again.

First Testflight with HM30, Stick Antennas, 5 km Range and Recording Camera Altitude 40m (130 feet)
Here the File of the Recording Cam:
https://drive.google.com/file/d/1-Wfsda9-i3NxFSEh5vdC1jnghjMGqz4j/view?usp=sharing
This can be played with the recommended App PotPlayer only.

And here the video recorded with a screen recorder when playing the PotPlayer with that File.
https://drive.google.com/file/d/1-MPpHUpleYqebUXHqDrVtbOwY6KGTgOO/view?usp=sharing

Two Results:

  • Range 1000 m until the download Video frozen.
  • Recorded Video from the cam verry bad quatlity or the Player for this format not useful.

A same second Testflight with the small Patch Antennas allowed a Distance to Home of 1450 m
until the Video frozen.
In both flights the TX commands and the Telemetry worked, happily.

Thanks for your reply,

On my side, I did not touch anything, maybe it’s my 12v 5A BEC which failed for a short time.
I already ordered a new one and will send the old one to Siyi

Interestingly, Google Drive recognized the .264 file and can play it within a web browser.

I downloaded the file and used ffmpeg to convert it with the following command:
ffmpeg -probesize 10M -i siyi_005.264 -c copy siyi_005.mp4

The output is playable on other media players but seems to contain a few artifacts that aren’t present in the original. I’m not well enough versed in ffmpeg to determine the reason.

Counterintuitively, I get a better result when re-encoding with x264 like this:
x264 siyi_005.264 -o siyi_005.mp4

All of this can be done for free using Linux or WSL, and you can install the required packages from the command line on a Debian based distribution like so:
sudo apt install ffmpeg x264

@Yuri_Rage Yes interesting.
Was the quality after your conversion OK or where the same ugly scenes?

I use Windos as OS and have no experience with Linux.

But there is another bad characteristic of the SIYI Cam. @SIYI
The image is heavily distorted. The street down is straight.
May be due to the large lense angle. Perhaps useful for Racing, but
NOT for FPV with Postprocessing and posting on Social Media.


So I will use another cam for this like Gopro or Fimi Palm.
