    Default Intermittent freezing in HLS

    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.

    ------------------------error message reports-----------------------------------------

    httplive error: EXT-X-MEDIA-SEQUENCE gap in playlist (new=101531, old=101529)
    httplive error: gap in sequence numbers found: new=101531 expected 101530
    ts warning: discontinuity received 0xc instead of 0x0 (pid=257)
    ts warning: discontinuity received 0xf instead of 0x9 (pid=256)

    main warning: picture is too late to be displayed (missing 13319 ms)
    main warning: picture is too late to be displayed (missing 13362 ms)

    ----------------------------------------------------------------------------------


    Pattern 2
    - error messages is reported after freezing(Video & audio stop) occur which same as Pattern 1.

    ------------------------error message reports-----------------------------------------

    httplive error: EXT-X-MEDIA-SEQUENCE gap in playlist (new=101523, old=101522)
    main error: ES_OUT_SET_(GROUP_)PCR is called too late (pts_delay increased to 1104 ms)

    main warning: buffer too late (-1050334 us): dropped

    I ask you a advise.
    Did you ever take this kinds of problem?
    If you are, I want to know the solutions such as changing the setting in Wowza server.

    Thank you.

    Hi

    You can start by checking the Wowza log files (in the /logs folder of your Wowza installation) and see if there are messages that correspond to the errors that you see. Also, I'd use more than VLC only for testing. Wowza has provided some simple players (in the /examples folder), and you may also test with goo.gl/5xGKKH
