Intel QuickSync Decoder - HW accelerated FFDShow decoder with video processing

[nevcairiel]

Ah, Haalis "feature" that replaces all AR definitions in the stream with the container defined AR. Too bad a TS file does not have a container AR.

[Blight]

egur/nevcairiel:
Was this reported to Haali?

[nevcairiel]

Its a feature in his book, because CoreAVC didn't have a option to ignore the Stream AR, so instead of adding that option in the decoder, Haali just overwrites the Stream AR with the container-defined AR. For MKV that might make sense, for any other format thats just terrible.

Anyhow, i have never seen him give any feedback whatsoever on issue reports on HMS.

[egur]

I get image corruption right after seeks on quite a few h264 TS clips.
After some testing, I've found out that Haali Media Splitter doesn't cause the corruptions. LAV and MPC do.
The first NALU after a seek with Haali is an SEI then a SLICE. The rest provide a SLICE NALUs without anything else.
Before posting a bug report (or feature request) to nevcairiel, does anyone have an idea on the differences?

Also, it seems that Haali is significantly faster at seeks or at least my decoder as well libavcodec produce a frame much faster. The difference is instant vs 1-2 seconds.

Can someone explain this behavior difference? Possible workaround?

[nevcairiel]

Its not a splitter "bug", its just not perfect behavior. You either ignore it, or you take steps to not show an image until its artifact free.
TS is not a format that was designed with seeking in mind, which means it does not carry any metadata about keyframes or such to make seeking easier.

Its already being tracked as an enhancement to try to find a key frame before delivery from the splitter, so the decoder has an easier job.

PS:
How does "nav" get into peoples minds when they read my name?

Very well, the snappy and clean seeks are worth the effort.

It means people are too tired when writing a post - corrected

I don't mind "nev", just i dont get where people get the a from, you're not the only one.

[HeadlessCow]

nev(cairiel) + LAV = nav

Probably.

With new version QS decoding doesn't work on any video o_O
ffdshow is prefered decoder, so on older versions it works perfectly. But with 1.17 mpc-hc is using next decoder (lav decoder, in my case). If I change QS decoder (in ffdshow settings) to libavcodec - ffdshow works as it should (but, obviously, without QS).
I've rolled back to older version - everything behave as it should. Than updated to new version - QS is not working again. So, problem is not in the system settings...
SW: MPC-HC 1.5.2.3456, nVidia driver - 285.62, intel driver - .2509. W7 HP x64
HW: i5-2410M + GT540M.

Just reinstalled 32 and 64 bit using the installers (they also register the filters) and no prb on mpc-hc 32 and 64 (same build as yours). All DLLs exist, double checked with dependency walker to make sure the debug builds didn't escape.
Even deleted the files in program files and reinstalled again, still works.
Does anyone else have issues?

well ,when I want to use this as decoder for potplayer I receive this error
"Unhandled exception occurred [0xc0000005@0x6EEA545A] at
IntelQuickSyncDecoder.dll
Additional exception information has been stored locally
and this application will be terminated"

and when I use mpc-hc it crash with this error report

by the way the system I yried this on have a core I3 2310m and
no discrete gpu only hd3000 and I have installed the latest Intel
driver

I've found a strange issue with potplayer - the HW vc1 decoder fails to play interlaced VC1 clips that mpc-hc and ZoomPlayer play well. This is a splitter difference. Using Haali or LAV splitters solve the issue. I'll look into the matter further.

Regarding MPC-HC I didn't have a single issue. I need more information:
* All videos crash or a specific clip? If a single clip, please share.
* Driver version
* splitter used.
* Renderer used.
* Other non default setting for player
* Clip has subtitles or not. Which filter renders the subs.

Did you try other splitters?

Download version 0.18 alpha:
32 bit http://www.multiupload.com/VWSVG172HQ
64 bit http://www.multiupload.com/AR3VDNBA6P
Source code http://www.multiupload.com/UQEUJB4WST

Revision highlights:
v1.18:
* Fixed FFDShow’s H264 sequence header parsing crash. A lot of users reported crashes with the last build. This was a long standing FFDShow issue that affected specific clips.
* Added black borders to images with non 16 modulo width. Retaining non standard width can cause downstream filters to crash (dvobsub/vsfilter).

With new version my problem was fixed. Thanks!

Great!

BTW, Potplayer's internal splitter is still not supported. So is WMC full screen. For the latter I have no clue as to why ffdshow is not loaded and since it's fullscreen exclusive it's impossible to debug with a single screen . If someone has any insight on this let me know.

I have an I7 2600k processor and two monitors (with two HDMI from the motherboard directly: no separate videocard)

My test is 4:2:0 interlaced PAL mkv MPEG2 file.

But when I run your FFDShow (with Intel selected for all MPEG2) I still get libavcodec running. And I have interlacing lines...

I'm using MPC-HC and am sure FFDShow is being used.

What can I do?

Note, I also get interlace lines with Microsoft's DTV codec.

Deinterlacing is (usually) performed by the renderer.
Try the following setup:
Select EVR as a renderer (in MPC-HC press "O" then "output").
In ffdshow configuration uncheck the deinterlacing check box.

Note that some renderers do not perform deinterlacing.

If you still see interlace lines (lack of deinterlacing), I'll need to see the clip myself. Maybe the clip is flagged wrong. Please share it (or a portion of it). A large clip will take time to download. www.multiupload.com is the easiest way to go.

Relatively high cpu usage, what are the details (resolution, CPU type, output surface format, etc.)
