Hi,
is there a way to display h265 encoded streams with OpenPLi? i have a Xtrend ET4000 with a recent nightly build but am not able to playback anything which has been encoded with h265. i thought ffmpeg can or has already been built with that support in openpli, right?

oh no 
! how is it possible that my 5years old notebook can handle h.265 just fine when hevc has been released and approved only in 04/2013? so the receiver is just not powerful enough to software decode? thats terrible.

Welcome to the club. Buy for example an 30 USD amlogic compatible box and be done with it. 
The purpose of SoC is to make money for the producer. And unfortunately cannot be upgraded with software codecs.

A set top box can show television in a very efficient way. It needs almost no CPU cycles to do so and also it uses almost no power doing that. Completely not comparable to a desktop, which clearly is not intended to be power-efficient. A completely different league.

The hardware must have a H.265 decoder. It must have a processor that is optimised for decoding H.265. Else decoding is very inefficient and you need a high power (PC) CPU to do so which of course is not present in a set top box.

Maybe a year ago it wasn't present. Now there are already models in market with H.265 like Mut@nt HD1265, Zgemma H5, VU solo4k ...

I got a few H.265 files last week and I spent a good part of the week looking at the best way to play them back on TV.
What I found is that hardware support is only available on SOCs which integrate a H.265 (HEVC) module and these are only found on 4K (UHD) players. I did not find a single HD media player which supports H.265. They all support H.264, but not H.265.
Software playback is troublesome. While looking around, I found many examples of players which "support" H.265 but forum posts all say the playback is jittered and not working well. Kodi and distributions based on Kodi such as OpenElec and LibreElec may work but I would not expect them to deliver near the throughput offered by hardware decoding and certainly not on the chips used in HD Sat receivers. To give you an idea of your box' throughput, run > openssl speed aes-128-cbc ... my DM8000, delivers 4 times less performance than my BCM5300 router, 20 times less than my Dual-core Celeron NAS and nearly 40 times less than my 6-year old i7 Mac.
Here are some examples:
* H.265 Players with hardware support: Dune HD 4K Solo with Sigma SMP8758 chip, Popcorn Hour VTEN, A-500 and A-500 Pro all with SMP8758 chip as well, Odroid C2 with S905 chip
* H.265 Players with software support: Zappiti 4K series and quite a few other Android-based players with Realtek RTD1195 SOC which supports UHD output and HEVC decoding but only on HD, not on UHD. You need the RTD1295 chip for UHD HEVC hardware support and only a few players use that chip. If you check forums, you'll see that feedback is not so good; the chip quickly reaches its limits. Also note those Android-based devices are basically beefed-up Android tablets; so nothing to compare with a real media player.
As mentioned by WTE in post #8, there are now Sat receivers with HEVC chips, so with the right "driver" and "image", it should be possible. Since I don't use my DM as a media player, I'm not sure what the OpenPLI team would have to do to make this work.

And if you connect an USB-stick/drive with the files directly to the TV?

Incorrect. The bcm73625, which can be found in quite a few new receivers, can decode HEVC and it's not a 4K capable SOC (it's even a bit low end).

And to be clear the BCM73625 is not doing any down-scaling from 4K/UHD channel to HD channel since it's output is limited to 1080p.
This kind of device will only be interesting when broadcaster will start pushing SD/HD content encoded into H.265 format to put more channels on the same TP (like some porn channels TP will start to do when H.265 will be largely available).

Which is quite likely the main reason for releasing it, and not 4K/UHD content. I think there are plenty of providers that want to squeeze more life (= money) out of their TP's.
Currently in use: VU+ Duo 4K (2xFBC S2), VU+ Solo 4K (1xFBC S2), uClan Usytm 4K Ultimate (S2+T2), Octagon SF8008 (S2+T2), Zgemma H9.2H (S2+T2)
Due to my bad health, I will not be very active at times and may be slow to respond. I will not read the forum or PM on a regular basis.

Hi,
it will first start with streaming. Amazon and Netflix will be among the first to use it.
ciao

i would like to get myself the mut@nt HD51 4K box, which has the BCM 7251s SoC, hence h265 support. i still have to figure out some things such as getting also a CI module (not CI+) which is certified or compatible with the austrian broadcasting companies (ORF, ATV...) on the other hand, there might be STB with the BCM 7252s SoC coming out later this year. Either from mutant or AX. We'll see.

Not sure about this box but be aware that having h265 in the SoC (as it must have, otherwise no UHD transmissions could be decoded) doesn't necessarily mean that there is also h265 support for playback of files (other than TS).
Posted 30 July 2016 - 07:53
Whot about play UHD coded in H264 ?
In internet is alot file who have this spec and on VU+ 4k boxes will be possible play?
Posted 30 July 2016 - 08:09
The Solo 4k doesn't support playback of 4K with h264
Neither does it support VP9.

- you make me curious. when h265 support is in the SoC, why would there possibly be no support for playback? how can i find out then if playback of h265 encoded files (other then .ts) is ensured?
