Geek asks and answers

Can you record video / audio on iphone while playing a separate video (with audio optional)?

Does any library support the iOS APIsimultaneous playback and recording of multiple videos? For example, does the interface support composition AVMutableVideo?

Can anyone explain the gist of the code? Does anyone know how this is possible? for example, is there a way to estimate how many videos in a given quality can play / record at the same time?

The AVFoundation library supports hardware accelerated playback of up to 4 videos at a time. Decompression is performed at the GPU level, so for most cases it works quite well. However, Iā€™m not sure about recording part of the question.
