Media Play and DLNA

These Samsung TVs are capable of playing serveral audio, video and image formats. These media contents can be played from an USB mass storage device (pendrive, USB hard disk), or from a DLNA network server. With firmware modifications it is possible to add support for media play over NFS or SMB/CIFS. This page tries to give detailed info about the playable formats, (the offical list does not go into details and also states that even with a supported media format not all content can be played) and also tries to outline the limitations of playing media content through DLNA using different DLNA servers.

Supported formats

Below is a table of the (more or less officially) supported media formats for USB playing (DLNA support may be different):

Unsupported formats

There are some audio codecs (apart from the exotic propriatery ones) that are unfortunately not supported. These are:

• DTS
• AMR
• OGG
• ALAC

The TV also known to have limitations for H.264 (e.g. MKV playing), the number of supported Reference Frames in the H.264 encoded content is limited. Some say that at most 9 reference frames are supported, however I personally experienced problems (Unsupported video format error, or instant TV poweroff) with 1920x1080 H.264 video with 8 reference frames.

DLNA

DLNA media play has stricter limitations than USB media play. This is significant reason for the firmware modifications to use NFS or SMB/CIFS (which should have the same limitations as USB media play). These limitations of DLNA include the following:

• You can't use features like FWD, RWD, PAUSE with some DLNA servers, and even with the Samsung PC Share Manager, sometimes (depending on media type and file size) some of these functions are not available.
• With some DLNA servers, some codecs are not supported when using DLNA but work fine via USB/NFS.
• You can't select the audio channel of a multi-language media file with DLNA playback.

Beside the Samsung software (Samsung PC Share Manager), you can also use the open source DLNA servers like uShare or Mediathomb. These can also be used on Mac OS X or Linux. On OSX, they're hard to install because you need to compile them by yourself. Out of the box, none of the media servers below (other than Samsung PC Share Manager) work 100% well. Below are tested programs with comments on current problems, maybe someone can provide some resolutions, and maybe it will help somebody.

Windows XP:

• Samsung PC Share Manager - Subtitles OK, all ok.
• Tversity Media Server - Unsupported file format on every video file, tried transcoding and etc combinations.
• FUPPES - Unsupported file format on every video file.
• TwonkyMedia - DIvX works, rest (including mkv) - Unsupported file format
• PlayOn + with plugin "LocalFiles" - randomly drops out from video, sometimes jamming.
• Mezzmo - Unsupported file format on every video file.
• CyberLinkMediaServer - no subtitles, no pausing, beside this everything works
• Asset - only audio
• Wild Media Server - (reported to work fine)

Linux:

• Mediatomb - By default, unsupported file format on every video file. However it can be configured to support every file the PC Share Manager supports (even with FF, PAUSE and REWIND support where the PC Share Manager would support it), except the subtitles.
• uShare - Unsupported file format on every video file
• minidlna - Works with C650, D6500 and HT-C5xxx series.
• MythTV - Built-in UPnP server works with D6500 series (even DVB-S/DVB-S2 recordings can be streamed).

Mediatomb

Use the latest (svn) version of mediatomb with compiled in ffmpeg support.

Add this to the server section of config.xml:

<custom-http-headers>
  <add header="transferMode.dlna.org: Streaming" />
  <add header="contentFeatures.dlna.org: DLNA.ORG_OP=01;DLNA.ORG_CI=0;DLNA.ORG_FLAGS=01700000000000000000000000000000" />
</custom-http-headers>

Configure mime types this way in section import/mappings/extension-mimetype:

<map from="avi" to="video/x-msvideo"/>
<map from="ts" to="video/mpeg"/>
<map from="divx" to="video/mpeg"/>
<map from="mp4" to="video/MP4V-ES"/>
<map from="mkv" to="video/x-msvideo"/>

Extend the protocol info in the server section.

<protocolInfo extend="yes"/>
