Media Features Summary

Supported Decoding Output Format and Max Resolution

Note: Before vaapi version(1.9.0), media driver only allow to create 16bit surface for 12bit bitstream decoding, padding bits will be filled with 0 by hardware. After 1.9.0 vaapi version, media driver is supported to create both 12bit and 16bit surface for 12bit bitstream decoding.

  • * For SFC path, there are NOT real 16bit, SFC precision is 12bit; For kernel path, we support real 16bit.
  • TGL/DG1/SG1 capable of max resolution: 16K; ICL/JSL/EHL/SKL/BXT/KBL/BDW capable of max resolution: 4k.
  • Composition path does not support conversion from BT2020 RGB to BT2020 YUV, BT2020->BT601/BT709, BT601/BT709 -> BT2020. So if some formats, RGB444 planar for example, are only supported by compositon path, make sure the color space isn't BT2020.

Supported Video Processing Feature Combination

Video processing has various feature filters including Blending(or Composition), CSC(Color Space Conversion), De-Interlace, De-Noise, Luma Key, Mirroring, Procamp, Rotation, Scaling, Sharpening, STD/E, TCC, Color Fill, Chroma Sitting, HDR10 TM, 3DLUT. These features can be divided into VEBOX/SFC/EU 3 categories according to hardware units. Generally, VEBOX+SFC or VEBOX+EU feature combination is valid and HW execution sequence is usually VEBOX first, SFC/EU second.

  • VEBOX: Chroma Sitting, De-Interlace, De-Noise, Procamp, STD/E, TCC, HDR10 TM, 3DLUT, CSC
    HDR10 TM is the feature for HDR video content, hence, not compatible with denoise, deinterlace, STD/E, TCC.
  • SFC: Chroma Sitting, CSC, Mirroring, Rotation, Scaling, Sharpening, Color Fill
  • EU (Media Kernel or Shader): Blending, CSC, Rotation, Scaling, Color Fill

Supported Media Copy

For media usage, there are a lot of interactive between CPU and GPU memory. To accelerate CPU<->GPU surface sharing performance, media copy is enabled to use GPU hardware engine or GPU kernel to copy the surface from/to CPU accessable location. It's supported from ATSM/Meteor Lake(MTL)+ platforms. You could get the detail API information from vaCopy.

Media Copy support most of formats like Nv12/p010/p016/ARGB/yuy2/y210/y216/AYUV/y410/ARGB10, and also popular resolution like 8K/4k/2k/1080p/720p/480p/320P, etc.

Besides, it's required that CPU start address need 4k alignment, you can refer: drm_i915_gem_userptr
