Can anybody tell me why this is being transcoded? Or, how I can find by myself which entry in the profile triggered the transcoding?

My first guess is the format profile being L5.1. I know all of mine are 4.1.

Thank you atc98092! That was very helpful.

I edited the profile file, and from the following Transcoding entry:

  Code:
      <!-- Transcode all h264 video with HIGH/MAIN > Level 4.2 on MPEG-TS stream with MPEG2VIDEO and ac3 audio transcoding -->
      <!-- expected profile MPEG_TS_SD_EU/MPEG_TS_SD_NA/MPEG_TS_SD_KO -->
      <Video targetContainer="mpegts" targetVCodec="mpeg2video" targetACodec="ac3" DAR="16:9" forceInheritance="true">
         <Matches container="*" vCodec="h264" profile="high_10" />
         <Matches container="*" vCodec="h264" profile="high" levelGreaterThan="4.2" />
         <Matches container="*" vCodec="h264" profile="main" levelGreaterThan="4.2" />
      </Video>


I removed the second rule:
  Code:
<Matches container="*" vCodec="h264" profile="high" levelGreaterThan="4.2" />


After restarting Serviio, it started delivering the above MKV in native format and the TV accepts it without complaints, and I get the subtitles track, which I didn't when it was transcoding. Doesn't this mean that this rule is not applicable to 2013 TVs?

In fact, your mkv file is not a true L5.1, the header value of the format profile (High@L5.1) is not true.

according to this : http://wiki.serviio.org/doku.php?id=get_h264_level
dpbMbs = (width * height * ref_frames) / 256
dpbMbs = (704* 480* 16) / 256 = 21120
Your file is a High@L4.0 profile

With previous Sony devices (2010-2012 serie), the value of the header is used by the firmware device, then video is not displayed ( viewtopic.php?f=7&t=7547&p=53909#p53909)
But it seems that 2013 model does not read the header value, but check the dpbMbs.

There is a serviio option H264LevelCheck ( http://serviio.org/index.php?option=com ... icle&id=16) with FILE_ATTRIBUTES value then
"- only takes into account the level computed from the file's characteristics (e.g. number of ref frames)"

Could you try this new profile and check detailed log if mkv is delivered in native format?
