Xiaomi Yi Sports Camera - Custom Firmware (Base 1.0.7) - Bitrate Increased to 30Mbps all modes

[samiluo]

If xiaomi yi cam is going to produce a dash cam, what do you guys think? Not officially released yet:

That typeface makes me think it's a Novatek based camera

BTW, where is the 2k recording update you talked about a lot?

a) would be nice
b) would be handy to have GPS with overlay in video
c) would be handy to have G-sensor output in video overlay

thanks all for sharing

BTW how to increase bitrate for 480p/240fps ?
I found in table https://github.com/funneld/XiaomiYi/blob/master/autoexec.ash/bitrate_map.txt located in 165-167.
BUT in my table, when I load from PRI on Bitrate editor, the last line is 158?
any advice ? thanks

Hi folks!

great thread and tutorials. Few questions if someone can help. I have Yi Z22L, Pretty satisfied (bang for buck). i Don't have that much issues with soft focus, tho there is a noticeable loss of details compared to GoPro4.
I have made custom fw with 25-35 Mbit/s for 1080p 60fps, since i notice lots of compression artefacts in night videos.

I didn't get is it possible to change to 2k rezo from iOS app or is it just via autoexec boot load to override default/last used video reso to 2k so it shows in iOS app 1080p but it is recording in 2k? Is it maybe better to hack iOS app via Flex 2 (great app, bought it in Cydia: http://cydia.saurik.com/package/com.fuyuchi.flex2/) to show hidden resolutions ?

Any hacks for photos jpeg quality?

Anyone tested hi bitrate on 240fps 480p?

cheers!

i see this thread is becoming a general question thread and dont feel like opening a new thread so il ask here.

i saw someone taking a few pictures and combining them together and the quialty was nice.. better then regular. something like HDR manualy.

is it possible to create a scrip that will take 4-8 picture with diffrent iso. and then we can combine them together with photoshop on 25% each one to get the perfect image?
maybe this is like burst mode , and if so, does burst mode take picture in "16 mp" quailty (same as regular picture quialty?)?

Hi guys one question, when i read this values and then check into the firmware all these hex address are over end of file. For example:

writeb 0xC06CE446 0x02

C06CE446 is not in the file, is over the maximum hex address in it. There is a number to subtract from C06CE446 to get the real address in firmware file? Thanks

 

[fuyghjb]

writeb 0xC06CE446 0x02

Its in RAM, not in firmware.

 

[StevenQX]

Its in RAM, not in firmware.

And i imagine that nobody (except some expert user) knows how to know where these information are stored in ram...right?

 

[fuyghjb]

Your adress its from RAM, it useful for scripts autoexec.ash .
Where is it in firmwaare i dont know.

Hello guys, is there anyone who has modified the firmware version 1.2.6 for the 22L ? Thanks in advance

 

[itzik]

never mind this isnt L version. its the regular..

 

[schnurbi]

Can we mod the firmware to record 60mbps in all modes?
