How does the openfang distribution work?

The openfang distribution consists of two parts:

  1. The custom U-Boot that alters the original firmware bootloader to boot from a microsd-card. This part does not contain any custom software, its just allows us to boot from the microsd-card. You only have to do this once.
  2. The ROOTFS, which contains the custom software. You will have to install them onto your microsd-card after you completed step 1. You can modify this part easily by changing the files on the microsd-card.

Does the openfang contain an RTSP-Server?

Yes, you can watch it through VLC Player.

Does the openfang connect to the Xiaomi Servers?

No. It does not connect to anything.

Does the openfang remove the original Firmware?

No. You can still boot the original Software, if you remove the SD-Card.

Can I run the openfang suite without a microsd?

No that is not possible.

Can I have full-HD support?

Yes, you can. After installing openfang, you can easily enable it in uEnv.txt.

See custom bootloader installation for more details.
