Looking at the graph, you will see the parameters used : x264 -placebo + no-psy vs x265 defaults

Maybe in a few weeks/months, when x265 has Weight P and Weight B working and more stuff borrowed from x264 (look at their TODO list), it will be more "fair" to compare...

I don't think those are specifically the problem. It's probably the rate control that is most important.

@ Kurtnoise:

I thought zerowalker asked for any comparison screenshots, not specifically from the test above. That's why I continued thinking about its general sense in the current stage of development...

Apart from other working features, there is also some need for useful default values. From my experience so far, a default quantizer of 32 in x265 is not really a sensible value.

Really love how development has picked up on the x265 project, I'm getting some good 'x264 vibes'

Is there a tool to decode the x265 generated raw hevc stream to another format at the moment?

The Osmo4 player in the GPAC Nightly Builds (Win32) can play it (muxed as MP4 with e.g. MP4Box in this package, or a current L-SMASH).

The HM reference decoder (ver. 12.0 currently?) can decode it to Y4M. JEEB's build (TAppDecoder.exe).

Wanna play with avisynth & libx265 on windows platforms ?

I've made a fresh compile of avconv from libav + patches from Daemon404...

Not all options from x265 cli are available yet but it's a good start.

Considering that you are a MeGUI developer: Is there any chance you could integrate it into MeGUI and roll it out via the development update server ?

Maybe...when hevc support in matroska (i.e in Mosu's mkvtoolnix, not Rovi) will be officially supported.

Same here. I hope some GUI like MeGUI etc could integrate this encoder. I would love to do testing with this new encoder.

gui support in MeGui and other tools will probably not come unless input via std::in is supported.
Most GUIs won't support tools which require huge temporary files as input.

Apart from that, x265 is not yet available for users, only for testers with sound background knowledge in video coding algorithms, and working with CLI encoders (at least by editing a batch file) is the least issue in the current stage of development.

There is no complete feature implementation yet.
There is no stabe set of command line options yet.
How often do you expect a GUI to follow sudden and unexpected changes in the set of encoder options?

And yes: There is not even support for streaming video sources (pipe / AviSynth) yet. GUIs could not efficiently serve frames to such an encoder.

Daemon404's test encodes are available in the directory.

Here are also a few of mine.

Also there are some new builds, compiled with MSys/MinGW GCC for x86 or with MSVC11 for x86 and AMD64 (latter may have a minimum requirement of Windows 7 and the MSVC 2012 Redistributable; a CPU with AVX support and 8 GB RAM are reommended): https://x265.cc/

who has created this buildbot ? It's from official devs ?

For MSVC builds, it's quite easy to support XP platforms and remove the c++ runtime.

I'll create a patch if needed.

The user registered with the nick "x265.cc" in the VideoHelp forum; I don't know if he is related to the development team.
