Yi Home (hacked V4) [SOLVED]

Monocle

Its hard to say why, but it looks like Alexa is immediately closing the connection (RTSP CLIENT SOCKET CLOSED) after receiving the SDP (descriptor). This is very common when Alexa does not like something about the SDP. However, to my knowledge there is no way to get any details from Alexa as to why she fails or what part of the SDP she is having an issue with.

In both example SDPs, they seem very sparse. Most cameras include much more details including video and audio codecs and other stuff.

Hi, thanks for the comments, only for clarify SDPs were cutted eliminating common lines in order to see only the difference between a one that works and one that does not works

@hulkyto

Can you include the complete SDP for both? I’ll take a look and see if anything stands out as odd for Alexa.

Thanks, Robert

@hulkyto

Try adding the tag @fake-fmtp along with your other tags. It’s a shot in the dark … but often times when Alexa disconnects immediately like this, it has to do with the a=fmtp:96 signature.

Thanks a lot, this finally works, proved on Yi Home 1080P Camera and Yi Doeme 1080P Camera both with Yi-hack-v4 0.2.0, thank you very much for your help, support and this great project!

Monocle

@hulkyto

That is GREAT news! Glad to hear is up and running!

If you get a chance, it would help others if you are able to post details on how to get these cameras working with Monocle and Alexa along with screenshots of your Monocle camera configuration here on the forums under the:

Home > Equipment / Hardware > IP Cameras / NVR topic.

I have had several other users ask about Yi cameras in the past, but I was not able to help them.

Thanks, Robert
