I am trying to configure the video toolbox encoder on iOS 10 (iPhone 6) to enable Single NALU mode for H.264. The default mode seems to be Non-Interleaved Mode where payload type of 28 (FU-A) is always used. From the Apple Developer API reference, the closest APIs for that would be kVTCompressionPropertyKey_MaxH264SliceBytes and kVTCompressionPropertyKey_MaxFrameDelayCount for VTCompressionSession.
I want to set kVTCompressionPropertyKey_MaxH264SliceBytes to a value less than the RTP payload size and kVTCompressionPropertyKey_MaxFrameDelayCount to 1. However, those two API's are not ever supported in iOS: How to set MaxH264SliceBytes property of VTCompressionSession
So I would like to see if H.264 Single NALU mode is supported on iOS. If so, how to set it? Thanks!
