Hi @eonist, I found 4. today and thought it might be worth looking into. I played around with the code a bit but couldn't figure anything out - probably because the protocols for the buffering don't seem to be implemented in the project yet (unless I missed something) and one would have to rewrite a lot of code. Anyway, hope you're doing well and maybe have a little time to check it out. :D Moritz

Hey man, packed at work at the moment. Switching channels while recording is a deep task. Aka requires deep focus. Its exciting to see Apple embracing this feature in their new camera app. If you havnt seen the Apple event, it had a segment about this feature. Even recording both cams at the same time.

I'll watch it right away! Thank you! No worries, it's not that big of a deal :)

If I can't add features my self, because of work commitments, I'll probably start funding them through issuehunt.

That would be pretty cool! I really love this camera library for recording videos and taking photos so seamlessly. It starts recording without any lags whatsoever - so absolutely smoothly! Just switching the camera would be a nice feature :D

Yeah, I think I focused a lot on nailing the zero-lag part. I just did deep focus for a week to get the core stuff right. Then refactored now and then, and people added code etc. Like you. I will start funding this project next month or start improving it my self. Either or. Stay tuned ;)

You really did nail that part! Couldn't imagine using any other library exactly for this fact! Really looking forward to improvements (especially or currently only to switching while recording)! Maybe one could come up with some special ideas like filters (or something crazy), too, which would make this library stick out to an even greater extent - if there's time obviously. I'll probably launch my app in April and will be very happy to use this library 😌😁

Filters is super easy. Lets do that next. I did a code quality refactor yesterday, going to add better error handling with the swift 5 Result-type today. And then probably Add AutoLayout based UI in a fresh Xcode scheme.

Sounds awesome, looking forward to it! 😃 My next semester will start next week so I'm not sure how much time I will have. If I do have some time on my hands, I'll hit you up and try to help out :)

Added support for switching the different back-camera types. Its just a simple implementation. Working on support for triple camera module that iPhone 11 pro has now.
