does hevc encoder support the extmbqp feature on windows?

when I use the sample_multi_transcode to test the extmbqp feature,I find that h264 encoder support extmbqp, but h265 return error.

my devices is Intel core i7-8700@3.2GHz, my system is windows 10.

sample_multi_transcode.exe -i::h265 StandardSequence_cbr.bin -o::h265 test_1080_trans.265 -hw -cqp -extmbqp

Hi 


I could see the input streams for both of the samples had the same file name "StandardSequence_cbr.bin". Are you using the same input stream for h264 and h265. Would it be possible to share the input streams with us so we could validate the issue at our end.


Thanks

I dont know why my stream can not be uploaded, it always stays uploading, so I finish the uploading. And i think this problem is not related to the specific stream, you can use any stream to test the feature.

Hi

 

We are checking on this internally will get back to you when we have an update.

hi luyf,

 

The hevc encoder should support the extmbqp at least on Linux, see this post. Your code failed at this line of SMT and in this function

I guess this might be related to the hardware setup.

Could you try add "-lowpower:on" to the command line and see if it can be fixed?

I got another error when try add "-lowpower:on".

sample_multi_transcode.exe -i::h265 StandardSequence_cbr.bin -o::h265 test_1080_trans.265 -hw -cqp -extmbqp -lowpower:on

Hi Luyf,


Thanks for the checking.


This looks interesting to me since your first test already switch to low power mode internal, you should get the same result with this test.


Just double check your input file: StandardSequence_cbr.bin, are you using a elementary stream as the input?

yes,  StandardSequence_cbr.bin is a elementary stream, it's just a output stream from sample_encode. And as I tested using H264, it does work. 

H264:

sample_multi_transcode.exe -i::h265 StandardSequence_cbr.bin -o::h264 test_1080_trans.264 -hw -cqp -extmbqp

Thanks,


I guess there are some parameters to the samples might miss, let me ask dev team.


I will keep you updated.

Hi lufy,


Thanks for your patient, I think you are right.


Dev team told me they found out the HEVC support for extmbqp was turned off in Windows Driver for CoffeeLake platform.


I am asking them how they will fix it now, I will keep you updated.

thankyou for your reply, and I wish the extmbqp feature can be supported in most platform for developers. By the way, does the latest platforms(such as Ice Lake, Tiger Lake) support the extmbqp feature on Windows Driver?

This is a good question, thanks for reminding.


I think this feature should be support in all platforms, but let me double check.

Hi lufy,


My apology for not updating this issue, here are the investigation result from dev team:

IceLake Windows : MBQP is not supported.

TigerLake Windows : MBQP supported. MSDK tests passed.

Linux : the feature is supported both for IceLake and TigerLake

So for Windows, the feature is supported starting from TigerLake


If you want to use this feature before TigerLake, you should use Linux. Let me know if you have further questions, if not, we could close this issue.

thankyou for your reply, and I wish the extmbqp point can be supported in utmost platform for inventors. By the way, does the rearmost platforms ( similar as Ice Lake, Tiger Lake) support the extmbqp point on Windows Motorist?

yes,StandardSequence_cbr. caddy is a abecedarian sluice, it's just a affair sluice from sample_encode. And as I tested using H264, it does work. H264  sample_multi_transcode.exe-ih265StandardSequence_cbr. caddy-oh264test_1080_trans.264-hw-cqp-extmbqp Multi Transcoding Sample Version8.4.27.0
