 My **working notes** on looking at DLNA headers. ​ Specific to my setup (minidlna, Sony BDP) only -- using the wiki as a location to keep notes. ​ Not meant to be useful for people who are not me. :) My **working notes** on looking at DLNA headers. ​ Specific to my setup (minidlna, Sony BDP) only -- using the wiki as a location to keep notes. ​ Not meant to be useful for people who are not me. :)

 +Response from DLNA server is this:
 +
 +<​code>​
 +Contentfeatures.Dlna.Org:​ DLNA.ORG_OP=01;​DLNA.ORG_CI=0;​DLNA.ORG_FLAGS=01700000000000000000000000000000
 +</​code>​
 +
 +Using libdlna as a [[http://​libdlna.sourcearchive.com/​documentation/​0.2.3/​dlna_8h-source.html|reference]],​ it means that mine supports HTTP Range requests.
 +
 +<​code>​
 +/* DLNA.ORG_OP:​ operations parameter (string)
 + ​* ​    "​00"​ (or "​0"​) neither time seek range nor range supported
 + ​* ​    "​01"​ range supported
 + ​* ​    "​10"​ time seek range supported
 + ​* ​    "​11"​ both time seek range and range supported
 + */
 +</​code>​
 +
 +  * ** DLNA.ORG_OP=01 ** HTTP Range requests supported
 +  * ** DLNA.ORG_CI=0 ** media is not transcoded
 +  * ** DLNA.ORG_FLAGS=01700000 plus 24 trailing zeroes**: ''​dlnaVersion15Supported'',​ ''​connectionStallingSupported'',​ ''​backgroundTransferModeSupported'',​ ''​streamingTransferModeSupported''​
 +    * Supports DLNA version 1.5 (2006 spec)
 +
 +** HEAD Requests **
 +
 +Worth noting that the DLNA client sends three total HEAD requests. ​ They are identical, except the first one also includes a ''​User-Agent''​ string:
 +
 +<​code>​
 +User-Agent: UPnP/1.0 DLNADOC/​1.50
 +</​code>​
 +
 +<​code>​
 +Request Method: HEAD
 +Request Url: /​MediaItems/​224.mkv
 +User-Agent: UPnP/1.0 DLNADOC/​1.50
 +Host: 10.10.10.103:​8200
 +Accept: */*
 +X-Av-Physical-Unit-Info:​ pa="​Blu-ray Disc Player"​
 +X-Av-Client-Info:​ av=5.0; cn="​Sony Corporation";​ mn="​Blu-ray Disc Player";​ mv="​2.0"​
 +Getcontentfeatures.Dlna.Org:​ 1
 +</​code>​
 +
 +** realTimeInfo.dlna.org:​ DLNA.ORG_TLAG=* **
 +
 +minidlna always sends the header, safe to ignore it (see upnphttp.c)
