MKV files playing with flickering lines since upgrade

Hi,

I have a Samsung C and E series and since the upgrade to 1.6.1 mkv files play with flickering lines across the screen as if there is poor digital antenna reception. This is the best I can liken it to.

It was not like this prior to upgrade, the correct profile is listed in the settings and all other mp4 files play as normal. I also played the mkv files with vlc player on my PC and they play fine.

Not sure what the issue is? Couldn't find anyone else with this issue in the forum search.

What if you add this to the C or E (or whichever profile you're using) profile

  Code:
<AllowChunkedTransfer>false</AllowChunkedTransfer>

I have the same problem, and the "<AllowChunkedTransfer>false</AllowChunkedTransfer>" has added in profile, but didn't solve the problem :cry:

Re: MKV files playing with flickering lines since upgrade

Greetings,

I too have a Samsung UN32EH5300 using the E/F profile. I shut down the service, added "<AllowChunkedTransfer>false</AllowChunkedTransfer>" to the profile, started the service and still experienced the choppy video/audio.

I downgraded to 6.1.0 and all works fine again.

Just wanted to add my experience to the conversation.

Thank you for the great software.

I also have an E/F Samsung, and have been getting the same flickering/digital interference on my TV. Downgrading to 1.6 fixed the issue for me as well.

Guys, please send me PM to apply for the beta group. I will have an attempted fix for 1.7, so when the beta is out it'd be good to get confirmation it was fixed.

Re: MKV files playing with flickering lines since upgrade

The flickering is due to the Serviio server not being fast enough to transcode the X265 video to MPEGTS as is specified by the Samsung Profile. Verify this by looking at your CPU load and noting it is at 100% while transcoding. Depending on your CPU changing the transcode to MPEG uses less CPU and may result in < 100% and no flickering/breakup. The Samsung also requires the vbitrate to be restrained to 15KB/sec and for C/D models the Chunked Transfer line must be changed to the simpler <AllowChunkedTransfer>true</AllowChunkedTransfer> This is all documented in bitbucket for a 1.7 fix.

Return to Samsung
