This is broadcasting company in Korea.
We’ve used Wowza server to provide streaming service(video contents in IP).
This days new streaming service, using HLS, is released
The new service is executed by Smart TV which has software video player.
But there is intermittent freezing while playing the stream.
We use VLC player(Version 2.1.3) to check this problem(for same stream).
The below error(debug) messages is reported by VLC player while play the stream.
The freezing occurred every approximately 10~15 seconds.
Pattern 1
- error messages is reported after freezing(Video & audio stop) occur.
