UsendMii 0.3.0 is now available.

Changes:

• Works with New Nintendo 3DS.
• Showing all available IPv4 addresses.
• Improved web menu.
• Updated Bootstrap to version 3.3.6.

Here is my video to announce the new version:

 

Okay, one bug: The "L"-Button actually goes a page back and thus won't work as a button.

 

First of all: Amazing work glad to see this project alive

I tried streaming 2 movies to the WiiU but one of them didn't work.

Working Moive: MP4, 1.44GB, Lenght: 1h30m, 1920x1080, bitrate 2176kbps, 23FPS

Not Working Movie: MP4, 2.15GB, Lenght: 2h30m, 1920x800, bitrate 2063 kbps 23FPS

audio is pretty much the same.

The error says something like this: Could not load video, Reload?


Possible subtitle support in the future ?

Thanks M*

 

Have you done any latency testing?
And have you looked into implementing direct connection with the PC and the gamepad? I know some people made an opensource library for Linux in C that did this, but no update on that for a few years.

 

So it would be difficult adding subtitle support ?

 

@Majk there is an HTML 5 track tag for supporting subtitles with the .vtt extension (WebVTT). The Nintendo Internet Browser support it (not tested yet). I think it could be possible to add it. I'm going to look into it.

 

UsendMii 0.3.0 will try to pick the one installed in the vJoy folder.

 

oh ok.. i just found the problem..it doesn't work well with windows 10 vjoy :/

 

Not only is this amazing it is for mac! I LOVE YOU DUDE. #RespectTheMacintosh
