[HEVC] x265.EXE: mingw builds

[vhelp]

- news: tsMuxeR 1.10.6 / 2.5.5 beta just added HEVC codec support.

D/L beta version here: https://www.videohelp.com/download/tsMuxeR_2.5.5(b).zip

just tested it, and created my first hevc.ts file

Does anyone know what's going on with lossless coding? Haven't been able to produce lossless output even since the earliest versions, and it's been finalized in the standard as far as I'm aware. I've just assumed it's not a needed or important feature in early / mid development, but I'm bringing it up out of curiosity either way.

--qp 0 with loop filter etc enabled seems to produce roughly the same output as with disabled, though I haven't verified bit for bit. Output is ever so slightly, but still noticeably blurred as it seems to just average all the pixels in any given area. --qp 0 and forcing all I-frame behavior produces a result that's very close to the original and retains sharpness, but is still different. I don't know the math behind it, but thinking conceptually, wouldn't B and P frames still be very useful for lossless coding, despite the increased granularity?

Either way, been wondering about it as there's been no mention, and it isn't on the todo/roadmap so it's left a bit ambiguous, and though I doubt it'd just slip by everyone for months, possibly like a feature that's already implemented or thought to be working. Haven't known whether to bother reporting.

x265 does not support lossless encoding. Also it's not on there roadmap..

Hi, after build 0.6+ rev 31 when trying to encode in 10bit, x265 crash. Trying all different builds, but nothing works. Trying encode without pipe and leave in commandline only bitrate and --preset ultrafast the same problem. Can someone tell what to do with this or how to tell developres about this bug.

[Selur]

Trying all different builds, but nothing works.

works fine here using:

x265 [info]: HEVC encoder version 0.6+112-ef26367cd10c
x265 [info]: build info [Windows][GCC 4.8.2][64 bit] 16bpp
x265 [info]: using cpu capabilities: MMX2 SSE SSE2Fast SSSE3 SSE4.2

and:

ffmpeg -v -10 -i "H:\TestClips&Co\test.avi" -an -sn -threads 8 -vsync 0 -r 25 -pix_fmt yuv420p10le -f rawvideo - | x265-16bit --preset ultrafast --input - --input-depth 10 --input-res 640x352 --fps 25 --frames 429 --output "H:\Output\test_09_22_43_4510_02.265"

or

ffmpeg -v -10 -i "H:\TestClips&Co\test.avi" -an -sn -threads 8 -vsync 0 -r 25 -pix_fmt yuv420p -f rawvideo - | x265-16bit --input - --input-res 640x352 --fps 25 --frames 429 --output "H:\Output\test_09_30_34_1210_02.265"

attached the x265 version I used.

Can someone tell what to do with this or how to tell developres about this bug.

only real chance is to post on the developer mailinglist (the bug tracker on their side is just for 'show' and like it seems, not being monitored at all)

Normal release.
I fixed a bug x265 crash 10-bit in the source code. Site where I post their jobs assembly.

[Skarstorm]

I got a problem with the builds from http://x265.ru
when i run x265.exe i got a system error, missing of the MSVCP120.dll file
anybody got an idea what to do next ?

[Selur]

Install Visual Studio 2012 runtime,.... http://www.microsoft.com/en-us/download/details.aspx?id=30679

Install Microsoft Visual C++ 2013


This error indicates that there is a library from 2013 version.
Ie as assembly x265 were made on VC13

If you are on Windows XP you can't use his builds.
If your are on Windows Vista or Later you need the VC2013 redistributable.

I don't know if they are this useful.

machine-doll.ru/vc12/

Is (currently?) offline.

rename http://machine-doll.ru/vc13/ not http://machine-doll.ru/vc12/

[Skarstorm]

I installed Visual C++ Redistributable for Visual Studio 2013 from http://www.visualstudio.com/en-us/downloads/download-visual-studio-vs#DownloadFamilies_3
It works now without any problem.
Thanks

GUI for x265 encoding

Ver 1
Contains the standard libraries that run on 32 and 64 bit systems.
So also does not require installation avisynth



Ver 2
This version contains only libraries for 64-bit systems.
So as the system requires avisynth MT

[Selur]

@Fllear: Tried version 1 (since I assumed it would contain all the dependencies the tool needs)

• How did you manage to get distribution rights for neroaacenc?
• You should also include infos about the license of the tools you are using.
• When I click on the questionMark-button under 'Deluxe' I get:
  ---------------------------
  Error
  ---------------------------
  Error loading help file.
  ---------------------------
  OK
  ---------------------------
• Where does the default output width from 768 pixels come from? (seems like an odd choice)
• progress indication during audio processing seems to be proken it just jumps to 100% while avs2pipemod and neroaacenc are running
• what are you doing to the audio processing to get it that slow?
• doesn't seem to produce any output,..
• "What to do after the coding"->'Play sound' doesn't do anything,...

-> also please create a separate thread for you tool

How did you manage to get distribution rights for neroaacenc?

I think it doesnt really matter in Russia, its not a commercial software.

About this can be absolutely not worry.

[Selur]

I think it doesnt really matter in Russia, its not a commercial software.

Ah, okay. Thought you had a license to distribute the software.
Btw. that your program is not commercial doesn't really change anything, since the End-user License agreement states directly at the beginning:

End-User License Agreement
IMPORTANT NOTE
Nero AG licenses you to use this software package for personal non-commercial and/or technology-evaluation purposes.
This License does not provide any rights to reproduce and/or distribute this software package in whole or in any part.

Not sure about the rights regarding user licenses in Russia, just thought there might be a way to license the software for non-commercial tools that I didn't know about.

If such license agreements really do not matter in Russia, I would also recommend to use Qaac or FHGAACEnc with the required dlls from Apple and WinAmp (Fraunhofer) instead of neroaacenc.

In Russia(and Ukraine too) almost all home computers installed with unlicensed Windows.
Except notebooks with preinstalled Windows, some comes with Linux or FreeDOS.
And no one cares.

Thats true.

I would also recommend to use Qaac or FHGAACEnc with the required dlls from Apple and WinAmp (Fraunhofer) instead of neroaacenc.

Thanks. I think too that it is a good idea.
Very good quality AAC encoder.

Semi-OT:

Now there exists an HEVC subforum @ Doom9's site:

http://forum.doom9.org/forumdisplay.php?f=81

Have fun

[Selur]

small warning to those using x265: Do not use options with their default value or your encodes might abort with a warning:

x265 [warning]: extra unused command arguments given <1>

-> complained about it in the dev mailing list, just wanted to warn other users
wanted to let a batch of command lines run over night but 90% of them were not started since x265 aborted like this :/

[HelpVid]

How can we define the level "x265 [info]: Main profile, Level-3.1 (Main tier)"?One time it's 6.1 and now it's 3.1. What parameter is related to that?


What is the good level for 720p and 1080p?

[Selur]

atm. there is no command line option to enforce a specific profile@level combination, this is still too early in the development

[HelpVid]

OK. So x265 defines by himself the good level regarding the command line?

[Selur]

no clue if the choice is good, but yes it chooses the profile and level by itself
My guess it probably simply uses same basic decision based on the settings used and the basic profile and level restrictions, see:
http://en.wikipedia.org/wiki/High_Efficiency_Video_Coding#Profiles
and
http://en.wikipedia.org/wiki/High_Efficiency_Video_Coding_tiers_and_levels

[HelpVid]

Very good. Thx.

[Fllear]

Fix version 06+188

x265 VC13

[x265.cc]

x265 VC13

It's VC12 or Visual Studio 2013


VC13 would be Visual Studio 2014/2015, which is not available.. yet.

Hi, I used my PC to encode any video with x265 and if not set --no-wpp it's will be crash

my PC is http://valid.canardpc.com/ea0wc6

[Pepsilite]

Hi everyone.
I always have a crash issue when using x265.exe under windows 8 or 8.1 at the very start of the process. Does anyone have the same problem?

[LigH.de]

@ mindwin: Neither the hosters of this board nor all users in this thread live beyond the reach of copyright lawyers... Better safe than sorry.

@ Pepsilite: Please help us to help you. Windows 8.x 32 or 64 bit? Which x265 build (32/64 bit, compiler, version/revision numbers)? Which complete command line?
