How to enable HEVC HW acceleration in Media Sample?

Jump to solution

Hi all

when i ran sample_decode in HEVC HW mode,i got this error:

[root@localhost x64]# ./sample_decode_x11 h265 -i blue_sky.h265 -o blue_sky_h265.yuv -hw -p 33a61c0b4c27454ca8d85dde757c6f8e
plugin_loader.h :153 [ERROR] Failed to load plugin from GUID, sts=-9: { 0x33, 0xa6, 0x1c, 0x0b, 0x4c, 0x27, 0x45, 0x4c, 0xa8, 0xd8, 0x5d, 0xde, 0x75, 0x7c, 0x6f, 0x8e } (Intel (R) Media SDK HW plugin for HEVC DECODE)

Return on error: error code -3,    /home/lab_msdk/buildAgentDir/buildAgent_MediaSDK3/git/mdp_msdk-samples/samples/sample_decode/src/pipeline_decode.cpp    266


Return on error: error code 1,    /home/lab_msdk/buildAgentDir/buildAgent_MediaSDK3/git/mdp_msdk-samples/samples/sample_decode/src/sample_decode.cpp    501

 

if i ran that in SW mode ,it was OK.

 

[root@localhost x64]# ./sample_decode_x11 h265 -i blue_sky.h265 -o blue_sky_h265.yuv -sw -p 15dd936825ad475ea34e35f3f54217a6

then i checked plugin.cfg,didn't find hw_decoder:

my OS is CentOS 7.1 and the cpu is Intel(R) Core(TM) i7-4700EQ CPU @ 2.40GHz,lspci can get this:

00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06)

 

Maybe i do something wrong in HEVC or SDK installation?could anyone help me?

Hi qin, 

On Linux, we support only HEVC SW mode, the GUID for that is 15dd936825ad475ea34e34e35f3f54217a6, HEVC HW (Hybrid implementation for HSW and BDW) is not enabled as of now. There is nothing wrong with your install. 

Thanks,

one more thing:i ran HEVC decoder with 15dd936825ad475ea34e34e35f3f54217a6 and  got 25 fps for 1080P.But the <HEVC whitepaper> says that we can get more than 100fps on 1080P.is the Test in <HEVC whitepaper> working on HW mode?

Hi qin, 

The reason of getting low fps in your experiments is due to writing the output out to a file, that's why we have a write fps and hence low fps overall. To know the actual performance of the underlying hw and SDK, it's best not to write the o/p to a file. Please remove the -o cmd and check the o/p on your system. 

Did a quick run on 4th generation system, using ducks 1080p bitstream encoded at 10Mbps 30fps -
