Stream quality suggestion

[beaverdude]

Hi, not an issue, just a suggestion. I've noticed there is a dev trace left from cam tuning: /system/bin/impdbg

it's a simply encoder on-the-fly setup (I used recommended calculated bitrate for 1080p 15fps)

/system/bin/impdbg --enc_rc_s 0:28:4:2240
/system/bin/impdbg --enc_rc_s 0:40:4:1

to increase compression quality and bitrate. Please be aware - you have to provide strong wifi connection to handle more data.

Hope you can include that into sh and make configurable. Just in case.

HD->SD and back setting via app change will reset this hack, unfortunately.

Thanks for the tip. Since this hack still uses the stock wyze firmware, any increase of the video quality will also increase the size of files being uploaded to wyze's cloud storage, which can increase their operation cost.
