Question to Japanese speaking users (QSVEnc)

[Selur]

Could one of the Japanese speaking users please try to contact rigaya34589 (see: http://rigaya34589.blog135.fc2.com/blog-category-10.html) and ask him if he plans to update QSVEnc to support the latest drivers?

The latest available version (1.21 from april) does not support '--icq' and '--la-icq' and also freezes when using for '--quality' with a higher values then 'balanced' on longer sources. These problems should be fixed in the current drivers.
(problems don't happen with handbrake, so the sdk&drivers aren't the problem)

Thanks!

Ps.: May be the problems itself have already been fixed and it's only a problem with the cli,...

You may have tried this, but you can translate a website with Google Translate: https://translate.google.com/translate?hl=en&sl=ja&tl=en&u=http%3A%2F%2Frigaya34589.bl...135.fc2.com%2F

There seems to be an email address there and you could use a translation program to reply in the authors written language. Or he may be fluent in English also.

[Selur]

Yes, I can read the web page with Google Translate, problem is that doesn't answer the question whether QSVEnc is still developed and if the bugs I mentioned will be addressed.

[El Heggunte]

How about sending PMs to Chikuzen, VFR_Maniac, or JEEB

Since you are a programmer too, it's less probable that they will ignore your polite requests

[Selur]

Didn't want to bother someone specific and hoped for a volunteer.

[MaverickTse]

Didn't want to bother someone specific and hoped for a volunteer. :)

You can simply post your feedback in English on his blog.
Japanese programmers usually have no problem reading English.

There is a more recent post concerning QSVEnc here: http://rigaya34589.blog135.fc2.com/blog-entry-480.html
so I think rigaya will continue developing it.

Note that the "QSVEnc" refers to the GUI encoder plugin for Aviutl, while the CLI version is "QSVEncC"

Thanks, I also misintepreted the command line output at some point.
I thought the 0 was false and x was true.

Will post inside the blog, thanks!

Btw. to you know which command line freatures fall under 'RC mode available'? -> DOH, got it.

[Selur]

Argh, can't post to the blog since I can't get over the captcha, since it uses Japanese characters.

---------------------------
Wanted to report that:

a. icq, la-icq, .. should be supported in QSVencC starting with v1.8 (compare handbrake and it's source code)
b. when using a '--quality' value slower than 'balanced' QSVEncC freezes after a few thousand frames

Wanted to ask if:
a. 32bit versions planned
b. Vista support is planned
---------------------------

Would be nice if one of the Japanese speaking users could post there for me.

Thanks!

can you post the full commandline you've used and what message did you get when trying to use icq/la-icq?

[MaverickTse]

I can answer that there IS a 32bit version ALREADY.
see the --help print out in my post above:

while yours was:

Just in case you got the files from some wrong place, here I uploaded the two CLI executables...

[Selur]

can you post the full commandline you've used and what message did you get when trying to use icq/la-icq?

QSVEncC --check-features already indicates that icq&co are not supported. (they are using handbrake on my i7-4770k (desktop) and my i7-4702MQ (laptop).

Since on both machines icq&co work in handbrake they sure are supported through the Intel SDK.

Regarding the Vista support, problem seems to be that the SDK / buidl enviroment is Windos 7/8 in which SetThreadErrorMode is part of the kernel32.dll, which it isn't in Vista. (see: Changes in Microsoft Windows 7 vs Microsoft Vista SP1: kernel32.dll

please also check if '--quality high' works if you use '--la' or '--cbr'. (can't test atm. since I'm away from my normal machines atm.)

Strange, will so some testing and report back. (might be related to me feeding QSVEnc through a pipe not a file, but we will see)

Thanks for the help!

Comment by anonymous:

Intel HD Driver v3621 seems to have a weird compatibility problem with SDK2014 (API1.8)
That driver sees the API as v1.10, and in v1.10, there is a change in the way how LA is set.

From rigaya:

>>MaverickTse様
>ICQモードについて
3621ドライバで本来はICQモードが使えるはず、ということでしょうか…。

QSVEncの機能情報タブで表示しているのは、「MFXVideoENCODE_Query」を使ってチ ェックした結果でして、そこで「×」と出るので、てっきり3621でもダメなのだと思っていたのですが…。 どうしてICQが使えないのか、調べてみます。

>Vista
正式にサポートする予定はありません。これはVista環境がなく、確認できないためです。(Win7と8 .1は確認しています)

ただ、たぶん動くと思います。積極的に動かないように作ってるわけではありません。


>>3621ドライバ
うーん、API 1.10というのも妙ですよね、Media SDK 2014 R2もAPI 1.9のはずなので、「1.10ってどっからでてきた?」という感じです。わたしが気づいてないだけでしょ うか…。

The following are my translation:

>>About ICQ Mode
The 3621 Driver was supposed to be able to use ICQ mode...
Since feature info was checked using "MFXVideoENCODE_Query" and there is a X on ICQ, that means Driver 3621 actually cannot use ICQ...But why is it so...I need to check.

>Vista
No plan to support because I don't have Vista machine and therefore cannot test that. (Confirmed to work on W7 and 8.1 )

However, I did not deliberately make it fail on Vista.

>> 3621 Driver
umm... API 1.10 is weird. Media SDK 2014 R2's API is 1.9 only, so where is that 1.10 came from? Am I missing something....

It seems that rigaya did not visited this thread(or at least did not pay attention to it), but since he is going to investigate the ICQ mode and 3621 Driver issue, I suppose quite a lot of things will be uncovered and be dealt with sooner or later.

Thanks for keeping us here up to date

Intel's response on the API version problem:
https://software.intel.com/en-us/forums/topic/516207

About Vista:
Look at the release notes of Media SDK 2013 and 2014... there is no "Vista" under system requirement. Meaning Intel dropped support for Vista in the recent SDKs.
Rigaya himself did not use SetThreadErrorMode in his code.

[Selur]

Ah, okay. Thanks to him and yourself for clearing that up!

[MaverickTse]

-la may get freeze with scene-change detection somehow.
When using --la, try also --no-scenechange

rigaya just released a new version that automatically disable scenechange when using --la.

For handbrake, it is no surprise that they have better support for QSV... they have direct support from Intel!

they have direct support from Intel!

Oh, didn't know that.

rigaya just released a new version that automatically disable scenechange when using --la.

Nice! Will test once I'm back home and report.

Using QSVCEncC 1.23 and:

mencoder -ovc raw -noskip -vf scale,format=i420 -forcedsubsonly -nosub -nosound -mc 0 -lavdopts threads=8 -really-quiet -of rawvideo -o - -dvd-device "F:\TestClips&Co\DVDs\ElephantsDream\VIDEO_TS" dvd://1 | ffmpeg -loglevel fatal -threads 8 -an -sn -r 25 -pix_fmt yuv420p -s 720x576 -f rawvideo -i - -r 25 -pix_fmt yuv420p -f yuv4mpegpipe - | QSVEncC --y4m -i - --input-buf 3 --slices 0 --fps 25000/1000 --la-icq 23 --la-depth 10 --profile auto --level auto --quality best --bframes 16 --gop-len 0 --sar 64:45 --i-adapt --b-adapt --b-pyramid --lookahead-ds auto --trellis auto --colormatrix undef --output-file "H:\Temp\DVD_11_52_11_0110_01.264"

encoding freezes,..
- removing --b-pyramid does fix the freezing.
- lowering --bframes to 9 does also
-> seems like there's a problem with --bframes > 9 and --b-pyramid when used in conjunction

Can someone reproduce this problem?
I'm using:

Okay, adding '--no-scenechange' also fixes the problem seems like disabling scenechange when lookahead is used doesn't work automatically.

rigaya just released a new version that automatically disable scenechange when using --la.

-> needs also to be disabled for '--la-icq'

only works if I:
a. lower b-frames to 9 (or below)
or alternatively
b. disable --b-pyramid
-> adding '--no-scenechange' doesn't always help
