I am trying to stream a dvb stream and publishing it to wowza with ffmpeg,

rtmp works fine, rtsp works fine,

BUt the HLS stream lags some time, Video freezes for few seconds and continues. some times voice repeats.

Need urgent help, to solve this.

I tested it in vlc, dreambox and iphone all same issues.

Thanks in advance

Hi Harry,

It is probably because the video is h.264 High Profile. We recommend Baseline Profile. Newer devices have no problem with Main Profile, but High Profile is not recommended for HLS playback on iOS devices.

FFprobe results:

```auto
