The best way to get good hevc performance is bumping up the sdram freq. I have mine at 600mhz but 550 is probably achievable with most rpi3s.

These are the settings im using:

force_turbo=1
core_freq=500
sdram_freq=600
gpu_mem=320
#initial_turbo=0
over_voltage_sdram=5
over_voltage_sdram_p=6
over_voltage_sdram_i=4
over_voltage_sdram_c=4
over_voltage=2
hdmi_ignore_cec_init=0
sdram_schmoo=0x02000020
dtoverlay=sdtweak,overclock_50=100

I doubt these settings are optimal and some may have been superseded but they work for me.

With these settings, what bitrates work for you without skipping for a 1080p HEVC file?

this file is 10Mb/s and should play fine.
But it's more complicated than just bitrate. With a software decoder, different encoding option may be cheaper or more expensive to decode,
so it's hard to say exactly what will play.

Here is a 1 minute clip (~110MB) that shows both the video jerks on mmal player and the audio sync issue on both omx and mmal player:

Plays fine here, but freezes momentarily while moving around the menus, but mmal has always done that on my rbp3.

# vcdbg log msg 2>&1 | grep DTOK


# Kernel device tree status: DISABLED

Based on tip of LibreELEC.tv master (97201723, changelog) and tip of XBMC master (a8b701d4, changelog) with the following modifications: Build Highlights:
  1. New firmware with Pi2+ support
    popcornmix Wrote:Pi2+ isn't very exciting. It's a Pi2 PCB with underclocked Pi3 CPU (2837). Basically 2836 has become too expensive to produce for the small number of (mostly industrial) customers who still want to buy Pi2. So, there is now a Pi2+ for them for same price as Pi3, without wifi/bluetooth, and clocked at 900MHz.
  2. libnfs updates (mostly WIN32 related)
Build Details:
  1. Firmware (Sep 21):
    • platform: Enable support for Pi2+
  2. LibreELEC.tv:
    • scripts/mkimage: Add run mode, remember default selection, resize gpt… (PR:738, 1 commit, 3 files changed)
    • repository.kodinerds: change repo (PR:757, 1 commit, 3 files changed)
  3. XBMC:
    • [estouchy] exit button should execute the selected shutdown function (PR:10513, 1 commit, 1 file changed)
    • [depends] fix binary-addon install when not cross-compiling (fixes #16916) (PR:10515, 1 commit, 1 file changed)
    • [estuary] - drop some PVR viewtypes (PR:10503, 1 commit, 3 files changed)
    • [mingwlibs] a set of small fixes for ffmpeg build proc. (PR:10497, 6 commits, 4 files changed)
    • Ticket #16906 - Fix iEndOffset property when parsing cue files (PR:10521, 1 commit, 1 file changed)
    • Picture improvements (PR:10484, 5 commits, 3 files changed)
    • [Estuary] misc fixes and tweaks (PR:10526, 1 commit, 19 files changed)
    • Musicroles Menu Additional default nodes (00d113a6)
  4. libnfs:
    • Conditionally include unistd.h from libnfs-zdr.c as some platforms lack this header (6cde2aca)
    • WIN32: win32 does not have IFNAMSIZ (799abde6)
    • WIN32: Don't call assert() before all variables are declared. (4c3d809e)
    • WIN32: Add portmap to more include directives (b741a44f)
    • WIN32: Update the path to nfs-{cp|ls}.c (53f63446)
    • WIN32: fix compile warnings in nfs.c (563c1123)
    • WIN32: Use size_t for the rpc fragment size (c672db83)
    • more win32 fixes (6d3e9814)
    • compiler warnings (e53758fc)
    • Merge branch 'master' of github.comConfusedahlberg/libnfs (fc2501dc)

    • WIN32: Add portmap to the include paths (9a652705)
    • WIN32: remove references to onc-rpc (2601b424)
    • WIN32: Add include paths for include/nfsc for x64 builds (c000bf2a)
  5. inputstream.mpd:
  6. peripheral.joystick:
    • Fix extra semicolon in if statement (b77d587a)
  7. pvr.dvblink:

I don't know what to tell you. It doesn't here on my rpi2. omx and mmal are both fine on #0531, on #0602 things went south, and still haven't fully recovered, for me.

Audio gets further and further off the longer it plays, and even starts dropping out (both audibly and on the receiver DD indicator lights...)

This is playback from a raid array on another machine (or a dedicated NAS box), on a lightly loaded gigE network.

I'll test it too since I'm having similar problems with my Pi3 and MMAL.

Do you know which encoding options was been used for this sample? Do you have recommendation for encoding DVDs an BluRays.

I noticed something odd when playing this sample I posted earlier - https://www.dropbox.com/s/d2f4ldng0mksqz...i.mpg?dl=1
There is a sliding text at the bottom of the screen at 0:40s. With mmal that text is smooth, with OMXPlayer it is very jerky. Is it normal?
