Are you saying that because they aren't actively coming to your house and holding your hands away from the keyboard, the fact that they sell closed source hardware is neutral?
Itβs actually positive. Open source community has limited resources, so DJI proving this thing can be made to work well removes any uncertainty someone would have when starting their own project without that knowledge. It also affects the way people look at the feature - previously many would just automatically dismiss it as a useless gimmick, but DJI implementing it and people liking their implementation gives the idea credibility.
So the only reason nobody implemented digital video systems until now is that they weren't sure if it could be done, and DJI locking their stuff down is actually good for the hobby.
OpenHD. If you fly wings and 135ms latency doesn't bother you, you can build it yourself. Of course, it uses Raspberry Pi's proprietary Broadcom SoC h264 encoder, so much for open :)
Is TBS locking their proprietary protocol they use to differentiate themselves from commodity Semtech ICs good for the hobby?
