H265 decoding fails in Media Server Studio 2016

Hi ,

I am using the Intel Media Server Studio 2016 installed in Apollo Lake platform running on Yocto Genevi baseline linux.

When I am trying to decode a h265 file using the sample_decode application using following command:

./sample_decode h265 -hw -i basketball_1080p_4mbps.h265 -o out.yuv -p 33a61c0b4c27454ca8d85dde757c6f8e

I am getting the following error:

Return on error: error code -3, /opt/intel/mediasdk/samples/sample_decode/src/pipeline_decode.cpp       258

Return on error: error code 1,  /opt/intel/mediasdk/samples/sample_decode/src/sample_decode.cpp 630

The m_mfxSession.InitEx is giving MFX_ERR_UNSUPPORTED error.

My plugins.cfg in /opt/intel/mediasdk/plugins/plugins.cfg  is as follows:

[HEVC_Decoder_33a61c0b4c27454ca8d85dde757c6f8e]
GUID = 33a61c0b4c27454ca8d85dde757c6f8e
PluginVersion = 1
APIVersion = 273
Path = /opt/intel/mediasdk/plugins/libmfx_hevcd_hw64.so
Type = 1
CodecID = HEVC
Default = 0

When I am trying to run in SW mode using following command:

./sample_decode h265 -sw -i basketball_1080p_4mbps.h265 -o out.yuv

I am getting error as follows:

Default plugin cannot be loaded (possibly you have to define plugin explicitly)

Return on error: error code -3, /opt/intel/mediasdk/samples/sample_decode/src/pipeline_decode.cpp       348

Return on error: error code 1,  /opt/intel/mediasdk/samples/sample_decode/src/sample_decode.cpp 630

I could not locate any libmfx_hevcd_sw64.so for SW  hevc plugin.

How can I enable hardware decoding support?

Also If I need the sw64 plugin for hevc where can I get it?

 

Regards

Thushara.

Hi,

just to let you all know - we solved the problem with Thushara by setting ENV variables ("LIBVA_DRIVER_NAME", "LIBVA_DRIVERS_PATH") for libva and corresponding setting of the library-search-patch ENV variable "LD_LIBRARY_PATH" suitable for the used ApolloLake platform.

@Thushara, can you mark your question as SOLVED just to let everybody know, please?

Thanks in advance.

Best regards,

Markus

Hi Thushara, 

Media Server Studio professional edition have software plugin and the package you must have received doesn't have hevc sw plugins in it.
Also, when using software plugin either mention -sw or -p <guid for sw> otherwise it can results in the similar error. 
Regarding hevc hw decode plugin error, I will get back to you soon. Need to consult APL team. Will contact you through email. 

Thanks,
Surbhi
