Samsung C series profile
Posted: Fri Jan 27, 2012 11:56 amHi all,
I have a Samsung C series TV (Samsung UE40C6540) and am running Serviio 0.6.1 from my Acer Revo 3700 which so far has been working perfectly with everything I've thrown at it except a recently obtained an mkv video file that during playback constantly gets buffered ('preparing to play') from the TV throughout the film.
mkvinfo on the file produces this:
And doing 'ffmpeg -i file.mkv' reports the following:
I've well over a hundred other films, lots of them 1080 mkv's at higher video bitrates as well that don't exhibit the same problem. Wondering if it's to do with serviio trying to decode / downmix the 6 channels to stereo? I have transcoding set up to use both cpu cores and see that ffmpeg gets to about 135% cpu. The profile is the standard Samsung C series TV / Player profile that comes with 0.6.1, so any ideas what changes I could try to get this working?
Thanks!
