Hi guys
Using Universal Media Server2.6.5 with jumpy latst version.windows 8..
If I run the seup with my TV (Sony Bravia) on my network it works fine but when I tried using same on my sister home except they have Samsung 2013 32 inch smart tv...it detected "Samsung All Share" as renderer and when runs see following error in logs
ffmpeg.exe has a return code of 1! Maybe an error occurred
Also attached log..plese help

Anyone? I think it has to do with Media Renderder as the same setup works fine with my Bravia EX620 TV..
Did anyone have Samsung "S" series media renderer file? My samsung TV is 32 inch "S" series 2013 canadian version.
Model: UN32EH5000
Thanks

but needs expert advise..Does issue is becuase of above line? If its how I can increase my buffer size?
Thanks

Hi nomi.

I also had problems with the vbv buffer parameters but with slightly different error. You can follow the problem and resolution from here:

viewtopic.php?f=6&t=78&start=170#p6853

In short, the solution I finally chose was to change from Mpeg2 encoding to H264 (Mpeg4) encoding. This might have some impact on the computing demand of your server - so check the load to see that this is a viable solution for you. In my case there was no problem. So if you don't want to read the full story above, just patch the Samsung renderer profile (SamsungAllshare.conf):

#TranscodeVideo=MPEGPSAC3
TranscodeVideo = H264TSAC3

Not sure it will help you, but at least there is no vbv in H264
