Cannot find LA ENC plugin

[高__超]

Hi,

I am trying to use LA_EXT in Windows10 with KabyLake i5-7500 platform for both h264 and hevc encoding, but it failed. Media SDK Version is 2017R1.

mediasdk_release_notes.pdf says HEVC encode supports MFX_RATECONTROL_LA_EXT with lookahead plugin in page 12.

Par file:

la_ext_264.par:

-i::h264 test.264 -o::sink -gop_size 33 -dist 4 -num_ref 2 -u 4 -la_ext -lad 33 -async 50
-i::source -o::h264 output.264 -gop_size 33 -dist 4 -num_ref 2 -u 4 -la_ext -lad 33 -w 1920 -h 1080 -async 50

la_ext_265.par:

-i::h264 test.264 -o::sink -gop_size 33 -dist 4 -num_ref 2 -u 4 -la_ext -lad 33 -async 50
-i::source -o::h265 output.265 -gop_size 33 -dist 4 -num_ref 2 -u 4 -la_ext -lad 33 -w 1920 -h 1080 -async 50

Below is my command line:

It seems the Media SDK doesn't contain the LA ENC plugin. Please let me know how to get the plugin or how to use la_ext in Windows. Thank you.

Best regards,
