Possible hevc 10 bit HW decoding bug in current drivers

[Celio_A_]

Hi, i'm trying to decode and encode 10 bit HEVC using hardware on Kabylake i7 7700 processor, command line used

sample_multi_transcode -i::h265 "D:\Intel Media SDK Plugins\4K Demos\Samsung Journey Of Color 4K Demo.265" -o::h265 D:\TESTE.hevc -hw -async 10 -pe hevce_gacc -pd hevcd_hw -cqp -qpi 20 -qpp 22 -qpb 24 -u balanced -l 1 -gop_size 24 -dist 4 -num_ref 6 -bref -bpyr -ec::p010 -w 1920 -h 1080 -WeightedPred::implicit -WeightedBiPred::implicit -amfs:on -extbrc::implicit -pp

I'm on Windows 10, tryed the first media sdk driver release and the latest, both produce same problems, if i use hevc decode plugin from Media SDK 2018R1 it works perfectly but are too slow for decode > encode, i have uploaded the result hevc stream in attachment

Hi Celio,

I am investigating, I did a brief test and I got an error, is it the same as yours?

No, i don't get error it simple transcode with wrong colors, like the example mentioned above, it finish sucessfully but with wrong colors, the hevcd_hw decoder don't decode correctly the 10bit sample but software hevcd_sw works with no problem, but are too slow, can u investigate further?

Hi Celio,

Apologized for the long delay.

Dev team had review this issue and confirmed the issue solved.

Here are the detail if you want to check it:

• This issue was fixed in our latest release which has integrated the hevc_hw plugin, you can run it directly or run with "-hw" argument.
• Run directly will be successfully, run with plugin can reproduce the issue.

If you still have question, please post a new request so it can be tracked immediately.

Any news about this? I tested with the latet drivers from intel site and have same problem, this will be fixed in next drivers version?

[Mark_L_Intel1]

Yes, I can reproduce the issue now, here is the output:

Hi 

I am trying to run msdk_decode sample in ubuntu 16.04 LTS .

In the software implementation I am able to run without any issues...

but in the  Hardware implementation, I am getting the following errors 

• WARNING: Unsupported the FMO/ASO constraints!!!
• undefined behaviour   . src/msdk_decode.cpp 160

can anybody help me in resolving this issue?

Thanks

Hi Ranganadh,

Could you have a different post?

I am also not sure what command line are you using.

Hi Celio,

I didn't check this issue for a while because of other project, do you still have it?

I have report this issue to dev team and I am waiting for their response.
