Can't see FPV camera video from M300 RTK with sample app #407

Open seungbeom-son opened 3 years ago

seungbeom-son commented 3 years ago

I installed swift sample project with my own Bundle identifier & DJISDKAppKey.

It successfully launched and detected my aircraft, M300 RTK.

But, when I moved to FPV page, I could not get video from the M300 RTK.

What should I do to get video stream from FPV camera.

In addition, I also need to get video from the payload camera (H20) at the same time.

How can I do this.

Hi..

I have tried your solution.. It is not working..

I am really in trouble.. I am not able to assign source for M300 - using OcusyncLink. when I try to assign it gives me error. Please see below.

I have tried various combinations: Primary - Secondary channel - error code

  1. FPV - LEFT - 1008
  2. FPV - TOP -1008
  3. FPV - RIGHT -1008
  4. FPV - FPV -1005
  5. TOP - FPV - 1008
  6. LEFT - FPV - 1008
  7. RIGHT - FPV - 1008
  8. MAIN - FPV - 1005
  9. FPV - MAIN - 1005

I believe because of that I am not getting feed from drone..

Please help me out..

Best Regards, Himanshu

Hi,

I have updated M300 latest firmware.. I am using 4.14 DJI sdk..

I believe nimble is not attached with M300.. That is why while fetching camera it gives me nil value.. It also give nil camera list.

please see fetch camera code below.. It is same as provided in sample app..

fileprivate func fetchCamera() -> DJICamera? { guard let product = DJISDKManager.product() else { return nil } if product is DJIAircraft || product is DJIHandheld { return product.camera } return nil }

Best Regards, Himanshu

@HimanshuChowdharyIndia M300 can't work like normal camera, it uses ocusynclink to fetch data and decode it by using VideoAdapter(you can find it in FPV folder of DJISample). It also needs to set enable for hardware decode

@Matheus193dn I have gone through the documentation and I understands that initially we need to assign source as given in sample app (https://github.com/dji-sdk/Mobile-SDK-iOS.git).. I am following this sample code strictly... In fact I tried Sample code.. I am not getting any video..

HimanshuChowdharyIndia commented 3 years ago

@Matheus193dn

I am following same as expected in below mentioned file CameraFPVViewController.txt

CameraFPVViewController.txt

Please help me out to figure out where I am wrong..

@Matheus193dn Please tell me when I need to enable hardware decode... Before starting DJIPreviewer Instance or after??

@HimanshuChowdharyIndia You can try my worked sample code below, i cloned from dji sample so you can download whole project and then replace with your dji key https://github.com/Matheus193dn/Mobile-SDK-iOS/blob/master/Sample%20Code/SwiftSampleCode/DJISDKSwiftDemo/Camera/fpv/CameraFPVViewController.swift

@Matheus193dn FPV video is not coming in sample code you have shared.. I have added my DJI app key.. Then moved to FPV after getting connected with M300... I am not able to see video.. I clicked HardwareDecode.. Still I am not getting video..

I had the same issue and it seems when there is no payload camera attached it's just not possible to view the fpv video feed because assignSource requires two valid channels to be passed. Once I connected a payload camera as the leftCamera the code linked by @Matheus193dn worked just fine
