#  Refer to PS3.conf  for help

#  The  protocol string  is (for mpeg2)  :

#  RN:  Using the Philips  image  for  now.
#  UserAgent: regular  expression to  detect  the connected renderer

##  DLNA settings
##Use   the DLNA feature  seek by   time and   not  by   range
#  SeekByTime=true
SeekByTime=false
##--------------------
##  Transcoding/Muxing  capabilities
##Transcode codecs  for  video and   audio  engines  #
##currently  supported: MPEGAC3  or WMV  for video, PCM or MP3 for  audio
TranscodeVideo=MPEGAC3
TranscodeAudio=LPCM
##  TranscodeAudio=MP3
##Use   default  DVD buffer  size: false  =  greater bitrate  and   faster encoding,
##but can   generate incompatible  videos,  depends  of  your  media renderer
##DefaultVBVBufSize=false
DefaultVBVBufSize=true
##Muxing capabilities:  Does  the media  renderer supports H264  and   MPEG2 in a  mpegts  file  ?
MuxH264ToMpegTS=true
##  MuxH264ToMpegTS=false
##Does the  media  renderer supports DTS in a  mpeg  file ?
#  MuxDTSToMpeg=false
MuxDTSToMpeg=true
##Does the  media  renderer supports DTS wrapped  into LPCM in a  mpeg  file ?
#  WrapDTSIntoPCM=true
WrapDTSIntoPCM=false
##Does the  media  renderer supports LPCM in a  mpeg  file ?
MuxLPCMToMpeg=true
##  MuxLPCMToMpeg=false
##Maximum   bitrate supported by   the  media renderer  (0=unlimited)
MaxVideoBitrateMbps=0
##Max  Width and   Height supported by the  media  renderer (0=unlimited)
MaxVideoWidth=1920
MaxVideoHeight=1080
##Does the  media  renderer supports only H264  L4.1 at most  ?
##  H264Level41Limited=true
#Does   music files need   to be  resampled at  44.1kHz? TranscodeAudioTo441kHz=false
#Does   the client  need   to receive transcoded  video with minimal  delay ?  (Useful when  the  
client  has   a  small timeout delay) TranscodeFastStart=true
#Size of  the transcoded file  (unknown  length) sent  to the  renderer  (could  determine browsing 
failure/success)
#Possible values:
#                         -1: Specific  value working with  the PS3,  means  perfect  transcoding 
and   copying support (it's against  the  dlna  spec though)
#                           0: size attribute is NOT sent to  the renderer (defaut  value if this 
parameter isn't used)
#  100000000000:  100Gb,  if you want to  be  sure that  the media  file  is not  cutted  before 
the end   ?
TranscodedVideoFileSize=100000000000
##--------------------
##  Misc Files
##
##  If you   want  to  apply a  specific extension for  your transcoded  files:
#  UseSameExtension=mpg
##  Mime  types transforms (oldmime=newmime|olemime2=newmime2|  )
#  MimeTypeChanges=video/avi=video/x-divx
#  MimeTypesChanges=video/mp4=video/mpeg
##  Extensions management:  no  need   to  put something here,  as   the server's  default  
configuration  is tuned for  ps3
##  What  extensions  are forcefully streamed as   is (and not  transcoded)
StreamExtensions=avi,xvid,divx,avc,mpg,mpeg,264,tp ,m2t,m2ts,wmv,wav,pcm,lpcm,wma,aac,flac,mka,mp3,ai f,aiff,ogg,ts,mkv
##  What  extensions  are forcefully transcoded
#  Needed   for Philips Aurea that  can   only  handle mpg,  mp3
#  Not   needed  for Philips NetTV   that  can   handle many  formats natively
TranscodeExtensions=wmv,m2ts,tp,iso,mov,dts
