How can we use DJIWidget in a cocoapod framework

Question

I'm struggling trying to include the DJIWidget in our cocoapod dev environment.

We have a cocoapod framework with our DJI source, in which we'd like to include the DJIWidget as a dependency to use the DJIVideoPreviewer, but every way I try I can't get it to work, the main problem being the FFmpeg static binary.

With the old VideoPreviewer we used to have to create a fat library from the project, but the old videopreviewer didn't include the FFmpeg binary. The built framework could then be used with vendored_frameworks to load it via cocoapods.

If I create the Fat Library with DJIWidget like we used to, on pod install, we get the following error:

[!] The 'xxx-pod target has transitive dependencies that include static binaries

Another approach I took was to try to build the cocoapod from the project like so:

  s.source_files          = "DJIWidget/**/*.{h,m}"
  s.public_header_files   = "DJIWidget/**/*.h"

  s.pod_target_xcconfig   = { 'ENABLE_BITCODE' => 'NO' }

  s.vendored_frameworks  = "FFmpeg/FFmpeg.framework"

But then when I try to install the pod, the FFmpeg header files can't be found, adding the FFmpeg header files to public_header_files causes another error.

The documented way to add the code in https://developer.dji.com/mobile-sdk/documentation/ios-tutorials/index.html is not going to work for us

DJI have made the DJIWidget available through cocoapods now, https://github.com/dji-sdk/DJIWidget so this question is no longer relevant!

EDIT: For completeness, this is how they configured the podspec, specifying the headers using xconfig:

#
#  Be sure to run `pod spec lint DJI-SDK-iOS.podspec' to ensure this is a
#  valid spec and to remove all comments including this before submitting the spec.
#
#  To learn more about Podspec attributes see http://docs.cocoapods.org/specification.html
#  To see working Podspecs in the CocoaPods repo see https://github.com/CocoaPods/Specs/
#

Pod::Spec.new do |s|

  s.name         = "DJIWidget"
  s.version      = "1.0"
  s.summary      = "DJIWidget for DJI iOS Mobile SDK"
  s.homepage     = "https://github.com/dji-sdk/DJIWidget"
  s.license      = { :type => 'CUSTOM', :text => <<-LICENSE
