I just tried to connect my RPi3 to my new samsung tv but I’m having some trouble with home video playback. No matter what type of file I use the image freezes during playback and then caches up a few seconds later. It’s not at specific intervals as it would be if it was a framerate issue and I can have long periodes of playback without freezing or buffering. It only happens with my home video files, Not with movies. Some home videos are running 25fps and some 30fps, while movies are running 23.976fps, but I have a few movies running PAL or 25fps and they seem to be running fine. Some files are called.MTS some are mp4, but common for all is that they are appended to each other in a .mkv container.
I’ve set my rasplex settings to always change refresh rate to video playback, but turning it off doesn’t change anything. It’s still buffering.
When I connect the same RPi3 to my older samsung tv (LE32C650) I get flawless playback when running all files. It only happen when using my new samsung tv (UE40H6505). Also when I run the home video files using the samsung tv plex app on my new tv I also get flawless playback, so the tv is capable of playing the files, which means it’s got something to do with the combination of rasplex and the new tv.
I’ve also checked if it for some reason was triggering transcoding and that’s why it was buffering, but my QNAP ts-251+ NAS isn’t transcoding during playback and ram and cpu usage is steady.
Here are a few info files showing what files is causing the buffering. If you need more info please tell me and i’ll deliver.
Hope someone can help! It’s really frustrating my new tv is performing worse than my old.
