StaxRip 2.0 Support Thread

[-QfG-]

Hi stax, is there any chance to add DNxHR Intermediate Output in the FFMPEG section by Encoders? You can delete the "ProRes" button, "DNxHR" is the newer Intermediate Codec.

Here the inputs for DNxHR:

-c:v dnxhd -profile:v dnxhr_lb //Low Bandwidth. 8-bit 4:2:2 (yuv422p). Offline Quality.
-c:v dnxhd -profile:v dnxhr_sq //Standard Quality. 8-bit 4:2:2 (yuv422p). Suitable for delivery format.
-c:v dnxhd -profile:v dnxhr_hq //High Quality. 8-bit 4:2:2 (yuv422p)
-c:v dnxhd -profile:v dnxhr_hqx //High Quality. 10-bit 4:2:2 (yuv422p10le). UHD/4K Broadcast-quality delivery.
-c:v dnxhd -profile:v dnxhr_444 //Finishing Quality. 10-bit 4:4:4 (yuv444p10le). Cinema-quality delivery.

I don't know if i can add that himself, if anyone has an idea, how i can add this, please tell it me.

I can't encode directly via FFMPEG, because i need some Avisynth Tweaks (Inverse Telecine)

Greetings

Currently, I pause 3-6 months. I try to get more people interested maintaining it.

I greet everyone. StaxRip-x64-2.1.4.8-Beta.
QVBR (Quality Variable bitrate using bitrate) preset for Intel H.264 does not work. This has been observed in all recent beta. Whatever high bitrate I set, the program switches to QVBR-Q (Quality Variable bitrate using quality - 23). If necessary, I will indicate the exact parameters of my files.
Also, another presets for Intel H.264: LA (VBR Lookahead), LA HRD does not work for me. If earlier it was possible to set the maximum Lookahead Depth - 100, now the launch with any settings ends in a crash: Failed to initialize encoder. : invalid video parameters. QSVEncC.exe finished with error! :confused:
Please pay attention to these problems. thanks

[L E G E N D]

Hi, i would like to ask for some help.

the story is that i'm trying to encode an avisynth filtered video script with NVEnc h265 in StaxRip,
i use a lot of filters to do that, as shown in script below.

i choose NVEnc to accelerate the process, because the avisynth script contains a lot of filters.

usually encoding with x264/x265 CPU costs a lot of time, then eventualy i assume using NVEnc might get the fps higher ^^

so since i'm in x64 env, i installed avisynth+ for both version 64 and 32, and added the plugins to right places,
everything works fine, i get the video preview in AVSPmod just OK.

the problem is when i start to encode the video, the fps is just the same as when i use only cpu to encode,
the GPU does nothing to speed-up the thing. i used MP_PIPELINE to create a process for each filter with max memory set to 1024 Mb,
and still i get: gpu 3% and VE 9% and fps 24 (maximum). I kept monitoring the process of MP_pipeline and noticed that cpu actes only without the gpu.

my question: is there anything to do to help accelerate the encoding of avisynth scripts with NVEnc h265/h264 ? or am i missing something??

i'll leave more details down below:

@Legend, you need to monitor the CPU usage, to know what's happening.

I bet the CPU usage is low. Meaning, you're not taking advantage of the CPU speed for some reason. This reason could be that one or more of the AVisynth plugins is not working in multi-cpu mode.
To force multi-cpu, you have to put at the end of your script, only once:
Prefetch(4)

4 being here the number of CPU logical cores. You can set it up to 8 on your i7 setup.
Try that and it should solve your problem.


Note: I'm not sure that SetMemoryMax(1024) is required here...

First of all, thanks to responding ^^

you bet right, the CPU usage is 48~58 %. I don't know much about the Avisynth Plugins/Scripts Multi-core/Multithread support.
I kept monitoring the Mp_pipeline processes, they don't use much memory nor GPU. i tried removing the lines of setting max memory
from the script, and set Prefetch(8) in the end, but the NVENC behaves the same, CPU usage don't exceed 60 % and GPU is at 3% usage 9% VE.

My thought is that mp_pipeline is written in C, not CUDA, hence, it doesn't make the child processes of each filter profit from the GPU as it should be
in this case. so maybe there's no point in using NVENC when no GPU resources are not being exploited.

maybe the solution is to use Vapoursynth.

Thank you real.finder i tried the script above and got 100% CPU usage, performance jumped to 43 fps.
also there are some artifacts that show up periodically. i'll leave two pictures for comparison. anyway THANK YOU ^^.

[real.finder]

you can replace the old FastLineDarken with FastLineDarkenMOD4 for more speed and stability

yes that come from edeen, that why I hate using close sources plugins! you can't do anything about it, except change SetFilterMTMode("eDeen", 2) to SetFilterMTMode("eDeen", 3) or remove prefetch(8) from the block that has eDeen and in both cases you may get back to old speed (eDeen will be a Bottle neck)

edit: also you can replace
SetFilterMTMode("eDeen", 2)
SetFilterMTMode("Deen", 2)
eDeen(r=2, ty=14, tuv=21, ly=7, luv=10, hqc=true)
Deen(mode="a2d", rad=2, thrY=14, thrUV=16, min=0.5)
prefetch(8)
### prefetch: 20, 10
with
eDeen(r=2, ty=14, tuv=21, ly=7, luv=10, hqc=true)
Deen(mode="a2d", rad=2, thrY=14, thrUV=16, min=0.5)
### branch: 4
### prefetch: 20, 10
which give a faster speed (not same as prefetch(8)) and no artifacts

How to load VapourSynth with StarxRip?

I use python 3.8.6 and VapourSyntth R52

my test.vpy script, it's a sample from http://www.vapoursynth.com/doc/gettingstarted.html


from vapoursynth import core
video_in = core.ffms2.Source(source='Rule6.mkv')
#video_in = core.lsmas.LWLibavSource(r'Rule6.mkv')
video_in = core.std.Transpose(video_in)
video_in.set_output()


Virtual Dub 2 opens it well

https://forum.doom9.org/attachment.php?attachmentid=17539&stc=1&d=1604216164


I can run the script from command line too.

vspipe --y4m test.vpy - | x265 --y4m - --output encoded.mkv



StarxRip 2.1.4.8 Beta, give an error when open script:

https://forum.doom9.org/attachment.php?attachmentid=17540&stc=1&d=1604216495


When I chage

video_in = core.ffms2.Source(source='Rule6.mkv')

to

video_in = core.lsmas.LWLibavSource(r'Rule6.mkv')

StarRip give me another error:

I already put file LSMASHSource.dll into: "StaxRip-x64-2.1.4.8-Beta\Settings\Plugins\VapourSynth" and "StaxRip-x64-2.1.4.8-Beta\Apps\FrameServer\VapourSynth\vapoursynth64\coreplugins"

https://forum.doom9.org/attachment.php?attachmentid=17541&stc=1&d=1604216749


do some search, I found this post: https://forum.doom9.org/showthread.php?p=1816963#post1816963

stax76 said: "Let staxrip create a vpy script"

But how to do that?

[44vince44]

It means you have to open staxrip, click where you read AVS Filters (in blue) and select Filter Setup > Vapoursynth. It will change to VS Filters.
Then open or drag and drop the video file in staxrip, and build your filters from there (read staxrip doc).

Staxrip will build the script for you, and you'll be able to execute the process without the whole scripting method that is explained in Vapoursynth.

Thank!

[hevron]

I appeal to experts for help. Updated plugins on Update-Links Staxrip -Stuff.
Plugins_JPSDR: in the folder there are 8 pieces, which of them should be selected?
AVS-Stuff real.finder: avs 2.6 and up or avs 2.5 and up should be selected? Thank you.
Win10x64.

[44vince44]

hevron,

1) for JPSDR:
-default one in Staxrip releases is Clang W7 AVX to allow compatibility with older generation CPUs
-you can manually replace with Release tClang W7 AVX2 if you have a more recent processor (by recent I mean not older than 4-5 years approximately)

2) for AviSynth+, we use the 3.6xx fork, not the 2.x, get it here https://github.com/AviSynth/AviSynthPlus/releases

[hevron]

44vince44, thanks a lot for the clarification, Release Clang W7 AVX2 is more suitable for me.
This link https://github.com/AviSynth/AviSynthPlus/releases has AviSynth + 3.6.1/ Date = 2020-06-20, but we have Version 3.6.2 test 2 /Date = 2020-08-31
:thanks:

[44vince44]

You're welcome hevron!
I don't know where Stax76 got the beta, but I believe soon there'll be an official release. When Stax76 includes a beta in Staxrip, it's due to a specific fix that he has been expecting.

[DavidRyan]

I tried to use DSS2 as a source filter for the first time (StaxRip v2.1.3.0) as I wanted to try it on a variable frame rate MKV (from a DVD using makemkv). But I run into the following error every time:
https://images2.imgbox.com/97/40/o37wWjX3_o.png

Does anyone have an idea of what is wrong? I don't use vapoursynth, only avisynth so not sure if the "VS_In" refers to that. Checking in the apps-manage menu it says "DSS2mod - status OK". Here is the mediainfo of the file if that matters:

"Width : 720 pixels
Height : 480 pixels
Display aspect ratio : 4:3
Frame rate mode : Variable
Frame rate : 24.035 FPS
Original frame rate : 29.970 (30000/1001) FPS
Color space : YUV
Chroma subsampling : 4:2:0
Bit depth : 8 bits"

Would appreciate any advice if anyone has an idea on how to get DSS2 working.

EDIT: Resolved, as described below

[DavidRyan]

I tried to use DSS2 as a source filter for the first time (StaxRip v2.1.3.0) as I wanted to try it on a variable frame rate MKV (from a DVD using makemkv). ...

Does anyone have an idea of what is wrong? I don't use vapoursynth, only avisynth so not sure if the "VS_In" refers to that. Checking in the apps-manage menu it says "DSS2mod - status OK". Here is the mediainfo of the file if that matters:

...

Would appreciate any advice if anyone has an idea on how to get DSS2 working.

If anyone else has this issue, I resolved it by installing lavfilters. DSS2 requires lavfilters to either be:
- installed on the system
- LAVFilters.ax files in the \LAVFilters subfolder in the same folder where avss.dll is placed (not the case with staxrip)
- a path to the LAVFilters.ax files specified using "lavf_path"

[ChaosKing]

Makes sense, as DirectShow uses codecs installed on your system. DSS2 does *not* require lavfilter but it happens to be that it installed the needed codec on your system.
Why not just use ffms2 or lsmash?

[Mister XY]

A little problem. If I want to create a 2 pass video with ffmpeg, it saves the file ffmpeg2pass-0 in the Staxrip folder. The problem with this is if Staxrip does not have rights access to it will be prohibited. Can't you do it so that the ffmpeg2pass-0 file is saved in the Temp Files folder?
Thx

[44vince44]

Mister XY I confirm this. It's a bug. The command line of ffmpeg should include the -passlogfile option with the temp location specified. This is a real bug, I will create a ticket in github, mentioning your find.

The problem is solved by adding the custom switch -passlogfile "%temp_dir%\ffmpeg2passlog"

I've noted that as well in the bug report.

[Mister XY]

I must do anything wrong. I add this line -passlogfile "%temp_dir%\ffmpeg2passlog" to the custom line in ffmpeg window, but when start to encode i get this message.
Cannot write log file '%temp_dir%\ffmpeg2passlog-0.log' for pass-1 encoding: No such file or directory

[44vince44]

You're doing nothing wrong. The macro value is not being passed :-(
Another bug?

Not only %temp_dir%, but ALL MACROS are not passed from the custom line :-((((( It seems the custom line does not support macros.

So in that case, only as workaround, use a system env variable -passlogfile "%temp%\ffmpeg2passlog"
This will use the global user temporary folder (as defined in your system)

[Mister XY]

OK, i have also seen, that the macros did not passing. If i have set decoder to another decoder looks like software, dxva2 etc. i must set the crop values. If i set the values via macros, it did not pass.

It's not a permissions issue of being able to create or write files in the temporary directory, because the Staxrip log shown is being created and written there successfully by Staxrip.exe.

But two different tools as shown in the log -- mkvextract.exe trying to create "ID1 23ms English.aac", and then ffmpeg.exe trying to create "ID1 23ms English.m4a" -- complain as though files cannot be created in the "C:\Files\Staxrip\The.File_temp" temp area.

Microsoft's Process Monitor shows me the tools are receiving ACCESS_DENIED in their attempt to create those files, as though it actually is a permissions issue.

But Staxrip creates the log file in the temp area successfully, and I can create files in the temp area using File Explorer. Both Staxrip.exe and File Explorer are running as normal non-elevated processes. Running Staxrip.exe as administrator still results in the same failure for mkvextract.exe and ffmpeg.exe.

I've concluded that the issue this: In the path shown, C:\Files\ is a mount point. Meaning C:\ itself is an SSD drive, but C:\Files\ is the mount point of a multi-terabyte magnetic drive for work space. The successful temp folder creation & successful log file creation by Staxrip.exe itself receives REPARSE in response to the C:\Files\-involved path, but the tools simply fail with ACCESS_DENIED.

It seems like "suddenly" Staxrip processing cannot traverse a mount point. Staxrip.exe itself can still traverse that path; but not the tools being launched.

This happens with 2.1.5.5.Beta and 2.1.7.0.Stable. Note the log says "Windows 10 2009", and my WinVER confirms "20H2 19042.685".

If I run 2.1.3.0.Stable or 2.1.4.8.Beta against the same source file in the same folder setup, the tools are able to create and write to files in the temporary area just fine.

Some unintended consequence of how the tools were updated for long path handling? Or can someone refute these results, and you are able to use a mount point in the path under Windows 20H2 successfully; meaning I should continue digging for a more specific root cause?

[44vince44]

@Trench, is it possible to edit the properties of your C:\Files\Staxrip\ folder and set permissions (full control) to you as user? do mount points allow that ?
We must know if the problem persists after that.

[stax76]

@Trench

The only relevant change I remember is changing the current directory of the staxrip process to the video temp folder, this was not long ago. Before the current folder of the staxrip process was usually the startup folder where staxrip is located. That's something a child process inherits.

[44vince44]

When creating folders directly in C:\ the system does not give them proper permissions for free read/write operations. Unlike a folder created in the user's official temp tree, or in the user's tree more generally.
As we are discussing something happening with a temp folder, it is wise to check the permissions on the folder C:\Files\Staxrip\ in Trench's case.
This should not be considered as a problem in Staxrip, even if it used to work otherwise.

So, @Trench, please check and do the permissions change, or set your paths to locations that you have R/W control on.

[LazyNcoder]

@stax76 Can you please compile Staxrip more often?
I see there are more than 75 changes since the last release 2.1.7.0
I'm impatiently waiting...

Thank you

[Atlantis]

Question. I remember you said some time ago that you added a button for attachments in demux dialog to select none like Audio and Subtitles but I noticed it is not there.

[44vince44]

@LazyNcoder you should check up the Staxrip docs, downloads section. There you get links to the betas.
There have been 3 betas released since then.

Hi guys - I need some help with audio processing in Staxrip. Feeling really stupid right now as I can't figure out on myself what I am doing wrong.

Goal: import old interlaced footage, process the video and copy (or convert) audio to ProRes MOV with PCM audio.

I've got three types of source footage:

#1 miniDV AVI with stereo channel PCM audio - this does work as expected by setting audio to copy/mux profile. No problem here. A window pops up and asks for the audio track to get demuxed.

#2 HDV m2t with stereo channel MP2 audio

#3 XDCAM HD422 mxf OP-1A with 8 mono channel PCM audio

With #2 and #3 I just can't get any audio processed through the pipeline.

Staxrip stable 2.1.7.0 with local installations of
AviSynth 3.7.0
VapourSynth r52
Phyton 3.8.2150

Scripting runs through VaporSynth.

But no matter what I choose for audio as the profile, it doesn't get loaded when the video source gets loaded.
I can right click into the audio field and select the file again, then I get at least one track. That's ok for processing one file, but for batch processing hundreds it can't be the way to go.
Creating a ffmpeg -c:a pcm_s24le profile did not help either...

I have googled around for 2 days and read several threads but there must be something (setting/procedure) I am obviously missing.

Hopefully someone with more knowledge can give me a hint into the right direction?

[44vince44]

Can you please provide a mediainfo sheet of the source that has the problem, and a log of the processing as well (you may paste them in pastebin.com then link to them here). I'm sure we'll help once we got that information.

I thought it might be easier to supply a short clip I am using for testing (43 MB)
This is the m2t file:

And this is the Staxrip Template:

I am looking for a sample of the MXF source I can upload too and will provide a link then.

The default configuration would demux and decode it with DgMpgDec, but that don't run because ffms2 is defined as source filter. What you can do is changing the source filter back to automatic or MPEG2Source, or you can remux it to mkv:

Tools > Settings > Preprocessing > ffmpeg remux > Edit > Input File Types > ts m2t

In the next build m2t will be found as audio source file, but this might result in async audio, so I recommend DgMpgDec.

Many Thanks! Setting the source filter to automatic did the trick.

Since upgrading to 2.1.7 I am getting the following error for all encodes when using VapourSynth:

Script exceeded memory limit. Consider raising cache size.

My encodes will not complete
out of memory: 3087360

How do I increase the memory limit? I have searched and read, but I cannot find an answer.

[JKyle]

Since upgrading to 2.1.7 I am getting the following error for all encodes when using VapourSynth:

Script exceeded memory limit. Consider raising cache size.

This issue was raised right after the default setting for x265 encoding of vpy was changed from vspipe to direct reading without piping.
See this issue thread (https://github.com/staxrip/staxrip/issues/470).

You can solve this problem in two ways.

1) Select vspipe for Pipe in Input/Output section of x265 Options window.

or

2) get @DJATOM's new x265 build (https://github.com/DJATOM/x265-aMod/releases/tag/3.4%2B65) that is believed to have fixed this memory leak issue, and replace the current one with this new build. You need some more testing in this case.

See this issue thread (https://github.com/staxrip/staxrip/issues/470).

You can solve this problem in two ways.

1) Select vspipe for Pipe in Input/Output section of x265 Options window.

or

2) get @DJATOM's new x265 build (https://github.com/DJATOM/x265-aMod/releases/tag/3.4%2B65) that is believed to have fixed this memory leak issue, and replace the current one with this new build. You need some more testing in this case.

Thank you so much!

Thanks all. I've been out of the office the past three weeks, and just now getting back to where I can test this. Note we did also have a Microsoft Patch Tuesday since this was observed, and the machine has automatically restarted to apply those updates since then.


@Trench, is it possible to edit the properties of your C:\Files\Staxrip\ folder and set permissions (full control) to you as user? do mount points allow that ?

Agreed it's wise to check the permissions, given the evidence.

Although the point still remains that with the tools included and/or invoked by Staxrip 2.1.3.0.Stable or 2.1.4.8.Beta against the same source files in the same folder with the same set permissions, the temp area created by Staxrip could be written to successfully.

And also that using "Run as Administrator", for which those default permissions you're referring to grant Full Control to the Administrators group, hadn't avoided the issue either.



The only relevant change I remember is changing the current directory of the staxrip process to the video temp folder, this was not long ago. Before the current folder of the staxrip process was usually the startup folder where staxrip is located. That's something a child process inherits.

Interesting observation that I will keep in mind while continuing to investigate. As you might have noted from the log, the Staxrip program directory in my case is actually outside of the mount point area; in "C:\Users\Trench\StaxRip-x64-2.1.7.0-Stable" instead of "C:\Files\Staxrip". So that kind of current process directory change does seem reasonable to consider.


But today -- as I test this issue which duplicated 100% for files inside of "C:\Files\Staxrip", and for which I had to work around the problem by moving my source files outside of the mount point area -- today the problem no longer occurs.

Since I've been away and not changing anything about the test or the configuration, for the moment I'm assuming Microsoft's Patch Tuesday corrected something here; whether it was also related to process' current directory or not. The patch that applied in my absence was https://support.microsoft.com/help/4598242/, but I do not see any changes with obvious correlation attributed there, other than "unspecified security updates."

Therefore the problem no longer exists at the moment. But should this symptom return, I can pick up with the recommended tests and report back.
