@luckylz , thank's for answer... But i don't know what i need way... I mean, my skill in C very low for that... And i need see example, step how read anything metadata from files, without .NET etc...
I need it for my project...
I am developing additional application for Xiaomi Yi, where you can change all settings (iso, shutter speed, awb, noise reduct, etc). It stage some 80% for release first version...
Of course! I tried, and it works fine on my camera Xiaomi Yi (fw 1.2.13)!
I tould about this! All scripted commands possible send to camera, with method about i tuld you! I mean, no need search new solution!
LOL!!! You kidding me? This folly, and not realtime! I reply again: We say's about custom app for smartphone with new options (change iso like in official app change qualitty settings, etc...)
You are reading my mind :) I thought about develop custom client app with all possible options (like scripts). In cam-side implementation very easy.
Simple in Xiaomi Yi (side):
autoexec.sh
lu_util exec 'nohup tcpsvd -u root -vE 0.0.0.0 21 ftpd -w / >> /dev/null 2>&1 &'
(for active FTP server)...
