Hi,

We’re packetizing RTMP stream into HLS, and the resulting video stream plays without issue on PC and Android, but not on iOS. What happens in iOS is that there is a still frame, changing every few seconds. The audio continues to play smoothly.

The video is 30 fps, keyframe every 2 seconds

Have anyone encountered this issue or knows what it could be?

Thanks,

Alex
