build a new pc specifically for x265 encoding

[poisondeathray]

I will do some googling to try and figure out how to get a build of ffmpeg with nvenc included. I thought I read somewhere that prior to Pascal Nvidia / nvenc quality was an issue but with Pascal its "better". Guess I will have to see for myself.

zeraone's 64bit ffmpeg builds have nvenc compiled , but the 32bit doesn't .

Another issue you might have is decoding bottlenecks; you're probably going to be using CPU decoding if using ffmpeg alone. ffmpeg's hw accel is problematic and very buggy

It's possible to use purevideo or qsv to feed nvenc, but the only reliable way is through avisynth

or actually, another option is to use NVEncC by rigaya ; it does have a muxer now and can handle audio now I think (a long time ago it just encoded elementary video streams) . It does have --avcuvid , which enables HW encode/decode.

Re: H264/AVC encode via ffmpeg, an attempt to get the quicksync (QSV) working through ffmpeg instead of rigaya's QSVEnc app.

rigaya is not updating QSVEnc anymore. His last gateway version is 2.57 app (a front-end to intel's Media SDK) is the fastest, at 250 fps on my Dell Inspiron laptop i3-2370M, but only less-than 50 fps if I use ffmpeg as the gateway. And getting it to work through ffmpeg is buggy. There is a huge regression (of builds) through the current build, today that the encoder does not work. You have to download an old version from 2015, which I'm using now, to test Intel's QSV with. And, you have to have the latest media sdk loaded in your cpu unless your's already has the latest version. I'm not sure what is the latest version. But on some of my test encodes, (the one's that error'ed out) will say something like 1.9, and 1.11 required. My laptop has 1.4 and I can't seem to find the latest media sdk from any of those versions (1.9 and 1.11) . I'm stuck with v1.4 unless someone knows a better resource than I that will get me the latest version loaded.

But, according to sophisticles, you should be able to use Staxrip as the gateway to your cards hardware encoder. He says (though not in these exact words) that it will use the full command set of encoding parameters through staxrip, so you should get the maximum performance and quality through it. I can't use staxrip because my work pc is admin locked and anything that requires the registry or installation or avisynth will fail--and has on mine. Plus, I write my own software for these CLI apps like these.

In my honest opinion, you need the latest media sdk version loaded for your hardware encoder brand.

QSVEncC 2.57 is dated Sept 29/2016 ; I wouldn't call that "old"

FFmpeg h264_qsv works for me from a build yesterday. ~380-400 FPS on 1280x720 4Mbps encode with a haswell (HD4600)

Maybe you are using qsv for DEcoding ? The ffmpeg implementation for hwaccel is very buggy, that could explain the 50fps

But, according to sophisticles, you should be able to use Staxrip as the gateway to your cards hardware encoder.

Actually, staxrip uses rigaya's QSVEncC.

This is the build (below) that I just downloaded. And, I know it did not work earlier, but now it is, I think. Anyway. I am still not getting anywhere near the fps speed like I do in the stand-alone QSVEnc app. Also, the quality is poor.

The source is a 720x480 and but the ffmpeg encoding speed is aprox 40 fps. That's very slow. See below for QSVEnc encode of the same source, but at 230 fps.

Also, what are the specific parameters to use in ffmpeg to obtain better quality ?

[sophisticles]

Actually, staxrip uses rigaya's QSVEncC.

The reason to use Staxrip is because he wouldn't have to drive himself crazy trying to figure out what version of the of this or that he needs, it just works so long as you have the latest .NET installed and it doesn't need installing, it's just a 7z archive that you extract:

https://github.com/stax76/staxrip/releases

I don't know what OS domenic is using but so long as it's either Win 8/8.1 or Win 10 he he should be able to do test encodes with both his Pascal and his Skylake via Staxrip, if he's using Win 7 then which ever gpu is the primary one (I'm assuming the Nvidia) will only be testable.

[poisondeathray]

You want -c:v h264_qsv to call QSV AVC encoder in ffmpeg ; not -c:v h264 which is CPU

"ffmpeg -h full " will list all the options. Look under h264_qsv. Not all of them were working properly when I last tested (maybe a year ago), but they might be now

[vhelp]

ok. I must have typed over that pat of the param you just posted and conensidentally the encode worked, using the internal h264 version.

Now, when I add the correct param as you suggested, this is the same error that I've been getting for many of the builds that I've been downloading these past two days. So frustrating.

I still believe that I need the correct SDK version and that's why I can't get this to work in ffmpeg. However, you got it to work in your rig, I'm stumped

[poisondeathray]

Just to rule out a build issue first, download a zeranoe 64bit build , which I've confirmed works with -c:v h264_qsv

(The exact one I used was dated 2016.10.23 , or ffmpeg-20161023-89ec4ad-win64-static.zip")

Unless you have 64bit avisynth, use a video test file (like a random youtube video) as input . (Since the 32bit zeranoe builds do not have qsv enabled) , otherwise you can use other avs pipe utilities, but to keep it simple just use a video for now

[vhelp]

My laptop is a windows 7 home premium, 64bit version. But, I have the 32bit avisynth installed on this laptop. I'm pretty sure its 32bit version. Is there an avisynth param line that I can pass to test it, which version ?

You need 32bit ffmpeg with 32bit avisynth .

So you would have to build it yourself, but that defeats the purpose of testing for a build error on your end. Recall I said zeranoe only has 64bit implemented for qsv, the 32bit build doesn't. So the easiest way to test right away to rule out some things quickly is to input some random video into the verified working 64bit build just to see if it works. Then you can start looking at other things like sdk version, drivers if it doesn't work. qsvencc works on your configured system with 1.4, so ffmpeg should too unless you've selected a feature not available on an earlier version

As I mentioned earlier, I built a 32bit non free yesterday, and it still works with qsv, so nothing changed over that week, not a problem with 32bit. The build is different, enviroment is different

[vhelp]

ok, that seems to have worked. I fed a non-avisynth clip and it encoded the video. But the fps was very low:

* about 9 fps for a 1920x1080p though it should be 120 fps, and
* about 50 fps for a 720x480i though it should be around 250 fps

also, the encode would not work unless I fed the param string as such:

C:\tools\ffmpeg\ffmpeg  -i "g:\Test Source 2.mkv" -y "c:\videos\video.20161028Fri.ffmpeg_20161023-89ec4ad_h264_qsv_TestSource2.h264" -an -c:v h264_qsv

and my cpu resource is taxed at 100%

see below, the output is a bit cryptic to me. Its hard for me to tell if quicksync did the encode or ffmpeg.

No it's not working for you. That is libx264

Your log says

Stream mapping:
  Stream #0:0 -> #0:0 (h264 (native) -> h264 (libx264))

It should say

Stream mapping:
  Stream #0:0 -> #0:0 (h264 (native) -> h264 (h264_qsv))

Just for the notes.. the "Test Source 2.mkv" file is from the link, below. In case you want to check it out. Its an 1920x1080p 24p source from KarMa, over there, 2nd file. I downloaded both so I could test with them:

https://forum.videohelp.com/threads/380203-Why-does-x265-preset-fast-get-the-smallest-f...=1#post2463752

[poisondeathray]

I don't know why qsvenc 2.57 would work, but ffmpeg (the exact same build that Ive verifed works) doesn't . I don't think they increased the version requirement for intel media sdk. But you can try downloading a newer version

[h264_qsv @ 0000000002f009e0] Error initializing an internal MFX session

What does it say when you run

qsvencc64 --check-features

Besides reporting v1.4 (most recent is 1.19), there might be some other clues

[jagabo]

I'm in the same boat. QSVEnc works but ffmpeg gives an MFX error. Using ffmpeg-20161023-89ec4ad-win64-static.zip downloaded earlier today:

[h264_qsv @ 0000000002d587e0] Error initializing an internal MFX session
Stream mapping:
  Stream #0:0 -> #0:0 (h264 (native) -> h264 (h264_qsv))
Error while opening encoder for output stream #0:0 - maybe incorrect parameters
such as bit_rate, rate, width or height

If I replace h264_qsv with just h264 it works fine, encoding with x264.

[poisondeathray]

jagabo - which intel chip was that on?

This was mine, but omitting -b:v 4000 still worked . (-b:v is in bits for qsv, so -b:v 4000000 for 4Mb/s worked to hit the actual target )

Do you guys have you intel drivers up to date ?

I don't recall seeing ffmpeg bump up the intel media sdk minimum requirement , but it might be something higher now

[jagabo]

That was on my i5 2500K. I just tried it on my Celeron N3150 (HTPC) system and it worked there. And it worked on my i3 4130T system too. All Win7 64 bit.

[vhelp]

the sdk is currently at 1.19 but mine is at 1.4 and i can't find an update file or resource to update it to 1.19 and the Intel website is of no use unless you have PHD and want to give Intel your name and address for their media sdk suite/software. But i'm not compiling with c/c++ nor building any sdk. So I don't need that resource. I (or we who are lacking the support) just need the uploader file to update our cpu/computer to the latst sdk. I believe that this is why it fails because ffmpeg expect the latest version 1.19 since that is what it is compiled with. If we can find the 1.19 sdk, then *all* the features will be readily exposed and available.

If you run QSVEncC (or QSVEncC64) with the --check-features it will show you *your* most current available features for each hardware encoder on your cpu with *your* current sdk version. Mine is below.

download instructions for QSVEnc

1. its the last file, "QSVEnc_2.57_7zip.7z"
2. create a folder and copy all files into it
3. navigate to the x86 or x64 folder: ..\QSVEnc_2.57\QSVEncC\x86 or ..\QSVEnc_2.57\QSVEncC\x64
4. run QSVEncC or QSVEncC64 --check-features

From what I've read, anything with an "O" means feature not available. But I believe its the other way around. Its should have been written as, anything with an "X" means feature not available.

[poisondeathray]

It didn't work on "Test Source 2.mkv" from that thread for me. Maybe a downloading error or something, or corrupt container. Because it works on other mkvs for me

But the difference is I didn't get the same "Error initializing an internal MFX session" message, it just was "stuck"

But I re-wrapped it to mp4 and it worked. Or try another video in MP4

ffmpeg -i "Test Source 2.mkv" -c:v copy -an copy.mp4

ffmpeg -i "copy.mp4" -c:v h264_qsv -an -b:v 2000000 ff_qsv_2Mbps.mkv -y

[poisondeathray]

the discussion says they did raise the minimum , apparently it's the lookahead function added in 1.9

https://trac.ffmpeg.org/ticket/4831

But rigaya's must have some detection or workaround logic

But try adding

-look_ahead 0

  -look_ahead        <int>        E..V.... Use VBR algorithm with look ahead (from 0 to 1) (default 1)

[jagabo]

avc in mp4 gave me the same error. Adding "-look_ahead 0" -- same error.

[vhelp]

same here. only i'm now using a much smaller 720x480 24p clip for testing. ffmpeg is happy to process in any other format. Its just a matter of figuring out why MFX is not initializing in some peoples setups when using ffmpeg even though it is compiled with --enable-libmfx.

[poisondeathray]

It works on jagabo's other computers, a braswell and haswell . Just not his SB. You have a SB too. So maybe some HW features not supported on newer qsv versions? Each generation is faster with more excecution units, but also the quality is higher. And didn't you get an older 2015 ffmpeg qsv to work ?

That was on my i5 2500K. I just tried it on my Celeron N3150 (HTPC) system and it worked there. And it worked on my i3 4130T system too. All Win7 64 bit.

[vhelp]

I'm not sure it worked on the older ffmpeg. Maybe you can help me determine that. see below. Maybe jagabo can try that version on the one that isn't working for him. i'm about ready for bed, its 1:30am here. let me know, so i can go to bed already.

If anyone finds that version, (i don't have the link to where I found it) please encode that clip (in post # 106) and tell me if you get the same filesize as I did: 96MB

Enoding params are below.

yes qsv is working in that one . You can tell because stream mapping says h264_qsv instead of libx264

 Stream #0:0 -> #0:0 (h264 (native) -> h264 (h264_qsv))

great. i get about 40 fps for that 1080p but it was about the same for the 720x480p i did also. This ffmpeg version encodes to a large file. i'm not sure i am using the correct encoding parameters, that's why i asked earlier if you know some that I could try because for that same clip, Epaminaidos filesize was 24mb (in that thread i mentioned in post # 106). its a huge difference to my 96MB. increasing -q to a higher value only made the quality worse. so if there is anything i can do to enhance it and bring down the filesize as Epaminaidos, than, that would be great. well, let me get to bed. tomorrow is another day. Thanks for your assistance.
