问题
My AVMutableComposition which contains two locally stored video files plays fine on the iPad but cannot play via AirPlay Video.
My AVPlayer implementation works fine for regular AVURLAssets over AirPlay Video, just not for AVComposition assets.
Both locally stored video files play fine via Airplay Video when loaded as individual AVURLAssets.
Is this a limitation with AirPlay Video? Or is there something I need to do to the composition?
