Samsung C series profile

Hi 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:

  Code:

And doing 'ffmpeg -i file.mkv' reports the following:

  Code:

[matroska,webm @ 0x991f2a0] Estimating duration from bitrate, this may be inaccurate

Seems stream 0 codec frame rate differs from container frame rate: 47.95 (5000000/104271) -> 23.98 (24000/1001)
Input #0, matroska,webm, from 'file.mkv':

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!

it's probably high profile so it has to be transcoded.

Right, so that means it gets transcoded on the fly during playback? Is there anything I can do to get it to playback properly or will I have to transcode it manually myself with ffmpeg? Loving Serviio so far other than this little problem..

Have You tried playing it from usb directly on tv? If it does not play than it has to be transcoded on-the-fly. Or You can use handbrake (or ffmpeg) to transcode it and later play it without transcoding. Samsung C series supports profile up to 4.1 for h264 while Your mkv shows 5.1 level.

not true USB and DLNA are done completely separately.

its supposed to but i have myself found a few that still wont work, but if i alter the profile level using the link tool they then play fine.
