How is H265 performing now?
What formats seem to be working? e.g. 8bit 1080p @ 25, 30, 50, 60 fps?

anyone willing to post a clip onto you tube?

How is H265 performing now?

I'm finding all my movies/tvshows at 8-bit 1080p24 play fine without overclock and with fairly low arm cpu.

25 and 30fps are much less common. I'd imagine no problems with 25, but 30 may require overclocking.

We will never do 1080p at 50 or 60fps without dedicated hardware.
My 720p50 samples do play fine.

Good to konw.
I would have thought that only at 1080p and above would h265 really make a big difference in verse h264.
I think I read that 720p not much difference of 264 vs 265.

Great work btw. I am actually thinking o f replacing my Rpi2 for a Rpi3 just on the basis of your work on h665

I don't believe that is true.

HEVC is getting around 50% saving in bitrate for same quality across UHD, 1080, 720p and 480p in paper linked from here.

One issue currently is the H.264 encoders are much more mature than HEVC.
It may be easier to produce a good encode from a H.264 encoder as options are well understood.

To back up what Popcornmix has said, I am using test files generated using HandBrake.

I use a 4K original that I re sample down to lower resolutions, it has a lot of movement and high detail.
At 1280x720 (720p) @ 31Hz full screen plays perfectly at almost any quality setting, Handbrake recommend using 20 to 18 quality, (for some reason the lower the number the higher the quality) I've generated files using 12 quality which still play perfectly, which is a 125MB file for a 2 minute clip. This is true for both a Pi2 and a Pi3.

For 1920x1080 (1080p) HandBrake recommends a quality factor of 23 to 20, again lower is higher quality.

The 1920x1080 @ 31Hz full screen will also play perfectly on both a Pi2 and Pi3 but using slightly less quality than the 1280x720 sample.
On a Pi2 I can get to a quality factor of 24, I use 25 to compress my videos anyway, so that works just great. File size for this is 46MB for a 2 minute clip.
On a Pi3 I can get down to a quality factor of 15, so way better than HandBrake recommends. File size for this is 156MB for the same 2 minute clip.
So if you don't want or need perfect quality, a Pi2 will actually do the job.

Both my Pis are slightly over clocked and have a good heat sink, no fan.

Hope this helps.
Kevin.

Wow - very detailed. Many thanks. I thought the RPI2 wouldn't handle it, especially as the RPI3 have a higher clocked GPU vs. the PI2.

Wow - very detailed. Many thanks. I thought the RPI2 wouldn't handle it, especially as the RPI3 have a higher clocked GPU vs. the PI2.

Actually the firmware is able to request a clock boost in various scenarios.
HEVC is one where core_freq=400 and v3d_freq=300 is requested on both Pi2 and Pi3.
(if you have manually specified a higher overclock you will get the higher overclock).

The Pi3 does have a higher arm frequency and double width NEON so it can handle harder HEVC files.

I have found that build 314 works fine but from build 315 on it fails.

Build 315....

Yes there are a couple of bug reports:
https://github.com/Pulse-Eight/libcec/issues/342
https://github.com/Pulse-Eight/libcec/issues/343

and this commit is under suspicion:
https://github.com/Pulse-Eight/libcec/co...27c890ede4

Perhaps Milhouse can try reverting that commit to confirm it is to blame.
If so you can add your voice to the libcec issues.

If Milhouse would feel that is appropriate then I could test and report accordingly.

Thanks for the links

Can you test build #0523y: RPi2

It's similar to #0523, but with the following commits reverted:

I have just got home and tested it now and I can happily confirm that it works a treat. The Pi3 was fully powered off with the TV on standby. Then the power was applied to the Pi3 and when it started to power up the TV switched on then switched to the correct HDMI input of the PI3.


Great work and most appreciated

What will this mean now, in terms of those reverted commits....?

Please report it to @opdenkamp on the Pulse-Eight github in either of those existing bug reports. It really needs fixing upstream, as reverting those commits doesn't really fix the issue.

In build #0525 does not work the multimedia keys (stop, play, pause, rec etc.).

From build to build, the one works the other no function...

I have a Panasonic and find those buttons occasionally stop working.
Unplugging from main all CEC devices (e.g. TV) may also help.

WOW !!! Thanks @popcornmix it works perfectly
