4k MKV Files only audio

Hi I am new to this forum. Welcome everyone. I have 4K MKV file moves and when I stream them to my TV via airplay I only get audio and a thumbnail image. The movie still plays on my iPad Pro. All non 4K movies play perfectly. Is 4k MKV files not supported with the infuse app?

It depends on what codecs your TV supports via airplay. Check with the manufacturer. I’ve found that airplay built into the TV is not the same as airplay found on the Apple TV.

Oh cool thanks. I appreciate the help

At least before iOS 14, you could only airplay h264 and nothing else. Your iPhone/iPad that recorded in h265 would transcode on the fly to enable airplay.
