Why is My Audio Playing without Video on iOS Devices?
If the video on your live stream is not showing up on iPhones and iPads but you can hear the audio, this likely means there is an issue with your video codec. H.264 is the suggested video codec.
Most often this problem is the result of using VP6 set up as the video codec, as shown below:
What is an Encoder?
Both audio and video codecs have to do with your live stream encoder.
Encoding is a process used to convert the RAW video files captured by a camera into digital files suitable for live streaming over the internet. This process uses either a hardware or software encoder.
