Actually, regarding to projects like Openelec, prebuilt images are where fun starts for most people

Image building is simple - Linux (virtual) machine with few programs installed and two commands. What may be hard is to update Kodi or some other modification.

Would it be very hard to compile a more advanced version of ffmpeg? I thought about --enable-libx264 and --enable-libx265.
OpiPC would be much useful for encoding puproses, during the time when it just stays idle. I was able to compile x264/x265/ffmpeg on other Debian/arm machines. But this is not Debian. It requires something more than use of git or apt-get. Is it actually possible, or rather... "reasonably feasible" with OpenELEC without some special knowledge?

Hi!

I have playback issues on OPI PC. HD videos are stuttering in every couple of minutes. I tried playing them from both network and local drives.
I disabled everything from the gui, like rss, bluetooth, wifi, visual effects...

Is there any trick, tweak or hack to get the performace better or simply OPI PC is just not enough hardware for Openelec?
Thanks.

H3 and thus OPiPC is capable of 4K playback. Which image are you using? Unless it is without HW acceleration, it should work.

or wich HD content , did you tried different coded movies . or wich audio codec , like is it ac3 or aac etc

if you find it dificult to determine the codec you got mediainfo to see what the codecs are of a file

or you could play the movie in openelec en while playing press o then you got a overlay with information wich codec how many dropped frames etc .

And use a recent image of openelec older version could have the problem but is solved in recent images.

Oh, if you have by any change 10 bit video, then it won't work smoothly. You can check video codec and other info by pressing "o" during playback.

H3 is too weak for software h265 and maybe h264 encoding. However, it has hardware support for h264 encoding, but for that you would need special version, which is not easy to prepare.

This issue is general, I mean I tried every common formats, 720p web-dl/hdtv tv episodes, 720p/1080p scene movies with DTS, AC3.
Regardless the resolution and bitrate, all stutter all the time from both local and network storage.
With some movies the picture stops, audio continues at a point, then picture rushes.
No CPU overheat, no frame drops, cpu utilization is normal.

I got 2 OPI PC, tried both, I use latest image from jernej, OpenELEC-H3.arm-7.0-devel-20161026221506-r23113-g64b34b3-opipc.
I set up my MCE remote, installed keymap plugin, no other modification. On a j1900-based HTPC everything is fine.

So if you say video playback should be smooth I'll re-format the SD card and try the pure image without remote.
