[Feature]: Recognize allow_content_tools and support force_integer_mv

[rosetta-jpn]

What Feature?

Libva patch to configure allow_content_tools and force_integer_mv is merged.
intel/libva#795

If allow_screen_content_tools is set to true, the decoder reads palette mode info in intra_frame_mode_info() and intra_block_mode_info().
If palette mode is not enabled, then the encoder needs to fill has_palette_y and has_platte_uv to false.
So the driver need to recognize allow_content_tools (and palette mode) to produce a valid stream.

In addition, I would also like to ask adding force_integer_mv support to media-driver.

Thanks in advance.

What's the usage scenario would be benifited?

Video Conference, Content Creation

What impacted?

No response

Do you want to contribute a patch to develop this feature?

None

@XinfengZhang Do you have any timeline for this?

[XinfengZhang]

hi @rosetta-jpn , you could do some quick evaluation with hard code to enable integer MV
https://github.com/intel/media-driver/blob/master/media_softlet/agnostic/Xe_M_plus/Xe_LPM_plus_base/codec/hal/enc/av1/features/encode_av1_vdenc_const_settings_xe_lpm_plus_base.cpp#L387
change the value to 0xc0a080 to have a try.

to be safe, maybe also need add params.forceIntegerMv = 1; in https://github.com/intel/media-driver/blob/master/media_softlet/agnostic/common/codec/hal/enc/av1/features/encode_av1_basic_feature.cpp#L880

@XinfengZhang I tried on MeteoLake.

change the value to 0xc0a080 to have a try.

This doesn't make a difference on produced bitstream.

maybe also need add params.forceIntegerMv = 1

This makes the produced bitstream invalid (failed in decoding).

hi hiro, could you help dump the encoding command buffer and share it.

Nothing is output. I guess I don't build my driver in neither debug nor release-internal.
Could you tell me how to build the debug version driver?

Hiro, we have verified PR #1794, and it hard code to force use integer MV if you would like to have a try, and I will paste the data for av1 vaapi encoder later.
