One potential workaround would be to use flare.pub to publish all of your videos. When you upload them there is an option to add a web link. I don’t believe YouTube links work but Vimeo links definitely do. Then you could build a library on there and share links to clients such as nostr:npub18m76awca3y37hkvuneavuw6pjj4525fw90necxmadrvjg0sdy6qsngq955 and nostr:npub12vkcxr0luzwp8e673v29eqjhrr7p9vqq8asav85swaepclllj09sylpugg
The full videos will also appear natively on other clients such nostr:npub1w0rthyjyp2f5gful0gm2500pwyxfrx93a85289xdz0sd6hyef33sh2cu4x
It isn’t optimal, but it is an option.
