Could you check with MKVInfo ?
Read http://www.bunkus.org/videotools/mkvtoo ... ompression

It's transcoded, maybe the aBitrate is wrong..? Try enabling detailed logging, play the file and try executing the ffmpeg command from the log manually. Post the command here.

Attached is the last log file. I must say I can't distingush exactly the command that I am supposed to reproduce manually from the command line - I am also not familiar with linux and command line, so, maybe I'm missing something. Some Playstation renderer lines are at the end of the log.

However, some sound DO comes from the speakers, but it's just "bits" of sounds, a fraction of a seccond long, which occur at a few seconds of silence interval - like someone would play with a broken audio cable and the sound comes only when the cable is not interupted. But the bits of sound are so short that they came out from the speakers like pops and clicks and pufs...

I tried to make a plastic description of what I am hearing, so, bare with me.

Serviio use this command line:
ffmpeg -i "/volume1/video/Movies/City of Ember 2008/City of Ember 2008.mkv" -y -vcodec copy -vbsf h264_mp4toannexb -copyts -acodec ac3 -ab 192k -ac 6 -map 0:0 -map 0:1 -sn -f mpegts /volume1/@tmp/Serviio/transcoding-temp-14-MPEG2TS.stf

Try this :
ffmpeg -i "/volume1/video/Movies/City of Ember 2008/City of Ember 2008.mkv" -y -vcodec copy -vbsf h264_mp4toannexb -copyts -acodec ac3 -ab 384k -ac 6 -map 0:0 -map 0:1 -sn -f mpegts /volume1/@tmp/Serviio/transcoding-temp-14-MPEG2TS.stf

Try this :
ffmpeg -i "/volume1/video/Movies/City of Ember 2008/City of Ember 2008.mkv" -y -vcodec copy -vbsf h264_mp4toannexb -copyts -acodec ac3 -ab 384k -ac 6 -map 0:0 -map 0:1 -sn -f mpegts /volume1/@tmp/Serviio/transcoding-temp-14-MPEG2TS.stf

Okey, here is the result:

Sorry, I was not clear on my request.(I wish you could add into serviio library the resulting file and check on your TV)
We'll make differently:
Could you edit the profiles.xml file and modify the PS3 section like this (just add aBitrate="384")
And retry to play your movie.

  Code:

   <Profile id="4" name="Playstation 3" extendsProfileId="1">
      <Detection>
         <HttpHeaders>
            <X-AV-Client-Info>.*PLAYSTATION 3.*</X-AV-Client-Info>
         </HttpHeaders>   
      </Detection>
      <MediaFormatProfiles>
         <MediaFormatProfile mime-type="video/divx">AVI</MediaFormatProfile>
      </MediaFormatProfiles>
      <Transcoding>
         <!--
            remux MKV with any video to MPEG2TS and possibly change audio to ac3, also AVI with H264
         -->
         <Video targetContainer="mpegts" targetACodec="ac3" aBitrate="384">
            <Matches container="matroska" />
            <Matches container="avi" vCodec="h264" />
         </Video>
      </Transcoding>
      <LimitImageResolution>false</LimitImageResolution>
   </Profile>

@illico - After ammending PS3 profile with your suggestion, the sound is normal, loud and clear, without interruptions. Thank you!

I just hope that someone will develop more on the Playstation 3 profile.

Cool, I'll include it in the profile: https://bitbucket.org/xnejp03/serviio/i ... r-abitrate
