Question: can mkv file play on iphone?
Answer: But the iPhone doesn't support the movie format, MKV. ... As an iPhone user, you need to know that the iPhone's built-in player only supports h264 encoded mp4 and MOV video. So if you have files in the formats of MKV, FLV, RMVB, AVI, etc, you can't transfer them to your iPhone or iPad directly.
