Handbrake: Enable/fix QSV decoding for all QSV-supported codecs.

[ZaphodX77]

Originally titled, Handbrake Nightly 2017082601 does not decode in QSV when encoder is set to H265 QSV

Please describe the problem or feature request in detail:

I have a Kaby Lake & a Skylake computer, which both decode & encode H265 in QSV. However, Handbrake apparently has the decoding of HEVC shut off, even when switches are set to on when encoding HEVC with QSV. Since current & future Intel processors will be capable of this decoding, please unblock the switch to turn this decoding on.

What are the steps to reproduce this problem:

Turn QSV decoding on, and it doesn't work per the logs.

What version of HandBrake you are running:

Nightly 2017082601

What operating system and version and you running (e.g. OSX 10.11, Windows 7, Ubuntu 14):

Windows 10

Was there any error message or error dialog, if so please detail or provide screenshots:

"QSV": {

}
Then:
decoder hevc, not QSV on another line.
Which should look like: + decoder: hevc_qsv, as it does when going from HEVC to AVC using QSV.

Please provide the full activity log for the encode or scan attempt. You may attach the log as a file, post a pastebin URL to the log, or place the log inline below:

[maximd33]

have some glue where to fix and should check it during next week

[maximd33]

are you aware that you do 10bit to 8bits transcode ?

SkyLake should not support hevc 10bits but starting from Kaby Lake

[sr55]

@maximd33

[14:25:51] encqsvInit: H.265/HEVC Main profile @ level (null)

null?

[maximd33]

@sr55 ah, a good point - it is a separate issue but I will fix it as well

[ZaphodX77]

I have both Skylake & Kaby Lake processors, separately, in 2 computers. This was a Kaby Lake 8 bit QSV encode.

I shall be happy to test your fix. Thank you.

[maximd33]

encode is 8bits - correct,
I am more about input file and decode: any option you can dump and share mediainfo details from your input file or the file itself?

[ZaphodX77]

I don't have the input file now. I can use a different file with the same characteristics, IE 10bit H265. I am presently running an encode of this example for the log to give you.

[ZaphodX77]

This is the MediaInfo of the new file.

Encode Completed ...

[maximd33]

thank you for the details: it is clearly HEVC 10bit decode related
which I wanted to validate for quite some time already,
it is important to fix it and will look on it shortly.

[ZaphodX77]

8bit HEVC sources are also no QSV decode. It's coincidence that my prior encode attempt was 10bit.

[maximd33]

@ZaphodX77 I've checked this already,
let me ask you : when you refer to 8bits content, are you really sure that you did not disabled QSV decode at Tools -> Preferences -> Video -> Disable QuickSync Decoding ?

feel free to share Activity log details for this case.

[ZaphodX77]

It is not disabled for QSV. The other codecs setting is.

[ZaphodX77]

You're probably right about the 8bit being OK.

[maximd33]

@ZaphodX77 thank you for the confirmation

[ZaphodX77]

8bit did not work until I enabled the other codecs setting as well as for QSV encodes. I think these hidden switches should be moved to the Codec settings panel for clarity.

[bradleysepos]

Thinking about what we can do before release. Should we have an option to disable QSV decoding when using a QSV encoder, on by default? @sr55 @maximd33

[sr55]

There is already an option to disable QSV decoding in preferences.

[ZaphodX77]

My intent in starting this inquiry was to achieve QSV decoding & encoding simultaneously. It currently will fallback or freeze when QSV cannot decode a file. As I've said, having these switches on a page separate from the QSV & Non-QSV encoding settings tab is a bit confusing, and note my comment that the QSV decoding for non-QSV encodes must be set for the QSV decoding to work with the QSV decoding for QSV encodes switch also set. That's probably a bug.

I stand ready to assist in testing any builds for you. I'm receiving notifications from this thread. Thank you.

[bradleysepos]

There is already an option to disable QSV decoding in preferences.

Right, I guess I was confused by the options, and concerned about the number of times we have to tell people to disable QSV decoding when encoding with QSV.

Options in the screenshot above:

• Disable QuickSync Decoding
• Use QSV Decoding for non QSV encoders.

The first is pretty obvious. The second, I'm not entirely certain, mostly because I'm not certain whether QSV decoding is on by default. Perhaps a combo/select box with the following options would be more clear.

QSV Decoding:

• Always enabled
• Enabled only for non-QSV encoders
• Disabled

It would seem the second option is the most stable for release.

Edit: Tweak to make even more clear.

[ZaphodX77]

A good tweak would be to move that panel from preferences & put it on the encoding tab for video codec selection because sometimes QSV decoding does not work because of the input file. Takes it out of hiding, and makes the setting more obvious as a result. And yes, I think that having "Always enabled" as default would be best, because it will show if the QSV decoding process is not being used when this one switch is toggled. Anyone with QSV capability should want QSV decoding on when encoding, if QSV decoding works. It's faster, and saves system resources & energy.

[sr55]

1. it's not moving from preferences. It shouldn't be something users frequently have to adjust. There are issues to solve but they need to get solved rather than moving this to the main UI.
2. There is no reason why you'd ever want to use QSV decoding only for non-QSV encoders.
3. By Default, QSV decoding is enabled. If the checkbox is checked, then it's disabled, thus the 2nd option is grey'd out thus irrelevant.
4. Regardless of what you set any options to, QSV decoding path is only used for codecs we support. There is no "Always".

I may flip the logic to be more "natural". i.e

"Enable QSV Decoding"
"Enable QSV Decoding when using non QSV encoders"

Either way, the issue at hand here is we don't support the full set of decoding options available.

[bradleysepos]

There is no reason why you'd ever want to use QSV decoding only for non-QSV encoders.

Unless I'm mistaken, we seem to have issues with QSV decode+encode simultaneously. Is QSV decode useless when encoding with, say, x264/5? I admit I'm not fully up to speed on these things.

QSV decoding path is only used for codecs we support. There is no "Always".

Fair point! Strike "Always".

I'm mostly interested in how we can make the options more clear and the defaults more functional in the short term. Disabling QSV decoding seems to be a common fix; I was hoping we could find a combination that keeps it enabled for stable paths and disables it where it might prevent this common issue.

[sr55]

Encoder doesn't seem to matter. It just doesn't work in some instances regardless of encoder.

[bradleysepos]

Ah, then perhaps I'm down a rabbit hole that isn't too useful. Anyway, perhaps you will consider clarifying those checkboxes; the second could at least be reworded.

@ZaphodX77 Scott's right that QSV should be a preference, and mostly invisible to the user. Exactly the kind of thing we really don't want on the main tabs. The only reason this is all in discussion is due to bugs; once those are resolved it should just work and stay out of everyone's way.

[ZaphodX77]

Thank you for that assurance that it is going to be fixed instead of disabled.

[bradleysepos]

Thank you for that assurance that it is going to be fixed instead of disabled.

Indeed, the goal is to support what QSV supports, within reason.

Sorry if I hijacked this thread a bit; seems I was confusing some of your initial request with an issue that's reported periodically, where QSV decoding needs to be disabled to make an encode work at all. 😈

[maximd33]

@ZaphodX77 can you pls re-cap when your settings which does not work,
so I can re-view it more carefully?
I was under impression that the case can be closed.

[sr55]

@maximd33 This case Is for two things:

1. Enable QSV decoders for all supported QSV decoders when available. I.e vp8/9. NIot tested 10bit files myself. Not sure if there are issues there
2. There is still some crash/lockup/artifcating issues with qsv decoder. I don't have any sources for these problems yet unfortunately.

[maximd33]

@sr55 thanks
VPx - would it be nice to have or a must ?

[sr55]

nice to have.

[ZaphodX77]

The QSV decoding does not decode input HEVC 10bit at all. It decodes HEVC 8bit sporadically.

Whenever there is a problem with decoding by QSV otherwise, for any input, there is something "wrong" with the input file. As you may remember, Handbrake had a muxing problem some time back that I pointed out, and there could be a legacy of such files being around. It could also be from some generalized corruption that I don't know the details of. Whenever there is such a file, it is a rare exception, and I just switch to software decoding for that file.

[ZaphodX77]

Is HEVC decoding to be fixed for 1.1.0?

[sr55]

More likely post 1.1

[maximd33]

@ZaphodX77

The QSV decoding does not decode input HEVC 10bit at all. It decodes HEVC 8bit sporadically.

I would be interesting to see and try again some cases locally, any samples to see?

[sr55]

Easily reproduced by encoding an x265 10bit clip with HandBrake then feeding it back in, Software hevc is used when the source is 10bit.

I don't however have any sources that break 8bit decoding.

[maximd33]

thanks @sr55 https://github.com/HandBrake/HandBrake/pull/1066 should address 10b HEVC story

[sr55]

@agalin89 @maximd33

Would be a good one to close out if time permits. Couple of points to note:

1. There is a problem with 10bit hevc decode. Seems to be dropping lots of frames:
Can provide samples if needed.

2. Do we support decoding for everything QSV does? I.e VP9?

Thanks

[maximd33]

@sr55 agree, it should be solved.

1. There is a problem with 10bit hevc decode. Seems to be dropping lots of frames:

• can you pls try 7755 driver from https://downloadcenter.intel.com/download/29335/Intel-Graphics-Windows-10-DCH-Drivers?product=126790
• can you share "Hevc-10-1.m4v" ?

2. Do we support decoding for everything QSV does? I.e VP9?
HEVC/h264 are first goals,
VP9 should be in the list after we will make filters fully validated.
would we care about VC1?

3. It looks like the code to drop crop/scale doesn't account for anamorphic
needs to be investigated with "Hevc-10-1.m4v" available to try

[sr55]

1. No joy on the update. Looks like it's fine in 1.3.1 and fails in the nightly build so it appears to be a recent change. Sample shared on iRC

2. VC1 is pretty dead these days so I wouldn't waste time on it.

3. Provided.

Thanks

[agalin89]

Issue has been investigated.

In JSON configuration provided you are using filters. It means that QSV output frames are coming out to system memory and QSV works in "encode-only" mode.

I tested the same configuration on released binaries of FFMPEG.

FFMPEG 4.2.2 release has the same issue.
Latest master nightly build of FFMPEG works fine. @sr55 Seems we need to update FFMPEG in contrib to the next release when it comes.

Command line to reproduce the issue:
ffmpeg.exe -c:v hevc_qsv -load_plugin hevc_hw -i Hevc-10.m4v -c:v libx265 output.mp4

More investigations:
If you disable filters in your JSON configuration QSV switches to "full encode mode" and produces output frames to video memory directly and it works perfectly.

[bradleysepos]

Would be good if we can identify the necessary upstream patches.
