Unit firmware

[andrew867]

Probably not the best place to ask, but do you have any firmware builds other than what's currently on the Startech website? I'm asking because I updated my USB2HDCAPS and now the RTMP stream gets jittery after about 12-24 hours. Does your unit have this problem?

Another off topic note, the iPhone app (haven't tried it yet) called iShareView was released by "AEverView Technology"

Hi there,

I don't have any builds for the box as the OEM appears to be dead, the e-mail you sent is the first time I've seen any firmware for this box, I'm surprised I didn't see that on the startech website.

I haven't actually used the box much lately & never for more than about 5 hours streaming RTMP so can't confirm if I experience the same issue, I will give it a try though & report back.

I don't like the rtmp streamer on the box either as it's purposely limited to 720p, the box is actually capable of pushing out 1080p fine over udp and maybe rtp (I've yet to determine how to trigger that via the cmd port).

I'll also look into that firmware & maybe hack together my own =D

Oh the official software support for this box (USB2HDCAPS ) is such a disappointment. You literally can't even add a custom bit-rate on this thing; shocking!

I hope you work this thing out man, I really do as this thing is currently wasting away in a draw id love to be able to properly utilise it.

Thanks for replying to this - I'd forgot all about it!

From my messing with the protocol, you can set a custom bitrate. The software just uses pre-defined ones. The default on reboot [at least on mine] appears to be 18mbps, that is just for local network streaming though, I think the rtmp software on the box is limited to a lot lower.

I'll e-mail Startech and ask for GPL sources, see what they say..

Oh and @andrew867 - My device [with the original firmware] has been streaming a video & separate audio loop for 3 days without too many issues..

• The box expects the output to always be in sync - any change in audio, switching to/from DTS etc and it screws up. It'll skip & jump. The encoder actually tries to correct the fault.
• It always expects audio output, it appears to have "issues" when there isn't any!
• The best input I've found appears to be 1080@30fps with 48khz audio.

Looks like GPL sources for this box is a no go too - Startech were less than helpful!

I'll look into building alternative apps that'll run on the box, but not much else I can do with regards to the firmware. I've tried to break it down, but had very little luck!

MPMC do you reckon this box could do 60fps @ 720P? broadcasting?

[mpmc]

@S0UK I highly doubt it, see https://www.yumpu.com/en/document/view/24242368/pl330-h264-hd-encoder-sigma-designs

But, I'll see if I can get mine to do it.

@S0UK unfortunately I was correct, the chip is only able to do 30fps @ 1080p. I tried a number of ways to force it to output 60fps [at 720] - all of which crash the box completely.

Do you think it would be possible to introduce Microsofts (Mixer.com i.e Twitch equivalent) FTL protocol along side the current RTMP version. FTL is now officially supported in OBS which is cool and makes the broadcast near LIVE, give or take a second vs RTMP which is much slower.

Also:

This is also the same device as REX-HDGCBOX2

and

Supercast T3

@S0UK Sorry, I missed your message (again!).

Er, I haven't looked at getting other things running on the box yet, I'm trying to write a cross-platform app atm. Once I've done that I'll look into getting other things going on the box :)

Has there been any luck with this? I updated the firmware with what's hosted on startech.com, and now it only outputs a blue screen with garbled green mess on the bottom. Even a copy of the original firmware would be of great help.
