Modern Samsung TVs are able to play movie with subtitles from DLNA server, but subtitles require some non-standard extensions of DLNA protocol. What it means: using standard DLNA server you can watch movie, though without subtitles.
This patch adds some of Samsung proprietary extensions, just enough for subtitles to work.

What it does:
1. When listing a folder, append non-standard <sec:CaptionInfoEx> tag to each video item. This tag servers only as a hint for Samsung client to check for subtitle download URL using HTTP HEAD method.
2. Before playing movie, Samsung device issues HTTP HEAD request on video item. In FileRequestHandler::get_info method we look for subtitle file and return it's download URL in CaptionInfo.sec header.
3. The device retrieves subtitles from URL provided in CaptionInfo.sec header. This is handled thanks to existing blind request feature.

    Marcin Jurkowski,
    With this patch, subtitle works well on samsung TV, but i'm unable to disable subtitles by remote control.
    With Samsung PC Share Manager (windows app) i can disable subtitles, change font size etc...

    Hi, I have applied the patch without error. But it doesn't work. I use Wireshark to capture all the packets until playback, cannot find any matching field called "CaptionInfo" at the packet content. Am I missing anything? Thanks in advance.

    Regards,

    Hello r32190sf

    I didn't make it clear, but Samsung support is disabled by default. You need to enable it in configuration file.
    In your config.xml find element <protocolInfo/> and add attribute "samsung-hack" with value "yes". After modification it should look like this:
    <protocolInfo extend="yes" samsung-hack="yes"/>

    You should also configure custom HTTP header like this:
    <add header="contentFeatures.dlna.org: DLNA.ORG_OP=01;DLNA.ORG_CI=0;DLNA.ORG_FLAGS=017000 00000000000000000000000000" />
    I can't remember now if it's neccesary for subtitles to work, but it solves a couple of problems with Samsung DLNA player.
    Hope it helps.

    Regards

    Thanks for your prompt reply. It works! One comment: There should be a space between ...yes" samsung-hack... at the config.xml

    I've just tested this with the latest version of mediatomb, and it works like a charm. No problems applying the patch, and it seems to work as advertised.

    Any chance this might be applied to the development version and included in the next release?

      It's nice to see that something is going on again.

      I must warn you however that since this patch was submitted a bunch of new devices has been released to the market. They're known to have some issues with MT. Even with uri fix some devices still won't play movies.

      I'll try to take a closer look on that and try to improve support for newer Samsung devices in January.

      Hi

      You don't need to apply this patch. Although there's no release with this
      functionality yet, it's already commited to git repository.

      Simply checkout and compile source code (see
      http://mediatomb.cc/pages/download#dev_code). Remember that Samsung
      extension must be extension must be explicitly enabled in config file by
      setting "samsung-hack" attribute of "protocolInfo" to "yes".

        Would you be able to provide some more info step by step how to do that as
        I am not that familiar with compiling source code. Please note that i use
        headless debian. Thank you in advance
