Rasplex that doesn't cause transcoding?

rasplex

#1

I've installed rasplex on a spare Pi B+ and it can play some movies, but others are transcoded (Bluray rips to mkv).

Will a pi-3 be able to play all movies without causing the server to transcode?

Here is a movie that transcodes (copied from pms -> media info):

Short answer: Yes.

Long answer: Yes, assuming your settings are all correct (standard setup will do it) and there are no strange anomalies anywhere within your network. I have two 3’s and they’ll both do a HD Blu-ray with full DTS-HD Master Audio at the same time, streaming from a server salvaged from an old computer that was build in 2009!

Additionally, most of my movies are quite large in file size, some being up to 20gb (LOTR trilogy - each film) with both DTS-HD MA or Dolby TrueHD (disc dependant) and AC3 audio for compatibility. The Pi3 makes light work of them.

Rasplex hardly ever transcodes, except for H265/HEVC encoding. Whether it runs in a Pi B+ or a Pi3 shouldn’t make any difference.

Transcoding occurs on all of my 1080p mkv movies with width 1920 height 1088.

The problem is your H264 level at 5, RPi only supports up to 4.1 so PMS has to transcode

Ok, does the Rpi3 support L5 ?
