# 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](http://intel.github.io/libva/va_8h.html#a5ff39794f6201b8a68ccb0d0f934be1e).
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](https://dri.freedesktop.org/docs/drm/gpu/driver-uapi.html#c.drm_i915_gem_userptr)
