    Default ttml in smil failed after update to 4.3.0.02

    Hi,

    We have upgrade Wowza Streaming Engine to 4.3.0.02. Then a smil file with ttml caption will return 404 now.

    This is the error from log :
    2015-12-23 17:53:20 HKT comment server ERROR 500 - HTTPStreamerAdapterCupertinoStreamer.onPlaylist: java.lang.NullPointerException|at com.wowza.wms.httpstreamer.cupertinostreaming.file.HTTPStreamerCupertinoIndexPlaylist.getPlaylistStr (HTTPStreamerCupertinoIndexPlaylist.java:1246)|at com.wowza.wms.httpstreamer.cupertinostreaming.httpstreamer.HTTPStreamerAdapterCupertinoStreamer.onPl aylist(HTTPStreamerAdapterCupertinoStreamer.java:1153)|at com.wowza.wms.httpstreamer.cupertinostreaming.httpstreamer.HTTPStreamerAdapterCupertinoStreamer.serv iceMsg(HTTPStreamerAdapterCupertinoStreamer.java:498)|at com.wowza.wms.httpstreamer.cupertinostreaming.httpstreamer.HTTPStreamerAdapterCupertinoStreamer.serv ice(HTTPStreamerAdapterCupertinoStreamer.java:451)|at com.wowza.wms.server.ServerHandler.a(ServerHandler.java:638)| 0.128 - - - - - - - - - - - - - - -

    This is the smil file :
    <smil>
    <head>
    </head>
    <body>
    <switch>
    <video src="mp4:1.mp4" system-language="Cantonese" title="Cantonese" audio-bitrate="96000">
    <param name="audioOnly" value="TRUE" valuetype="data"/>
    <param name="cupertinoTag" value="EXT-X-MEDIA" valuetype="data"/>
    <param name="cupertinoTag.GROUP-ID" value="aac" valuetype="data"/>
    <param name="cupertinoTag.DEFAULT" value="YES" valuetype="data"/>
    </video>

    <textstream src="1.ttml" system-language="zho">
    <param name="isWowzaCaptionStream" value="true" />
    </textstream>
    </switch>

    </body>
    </smil>

    I found this error as soon as the update completed. So is there some config need to change after update?

    Thanks,
    Monica

    Hi,

    I think we need to see more of your environment in order to understand this more. Can you raise a support ticket and include a zip of your [install-dir]/conf, [install-dir]/logs, [install-dir]/transcoder, and [install-dir]/manager/logs files. Please also include any smil and caption files and any other detail that will help us to troubleshoot.


    Regards,

    Paul
