Processes That Can Be Accelerated With VA API
Video decoding and post-processing processes that can be offloaded and accelerated if both the device drivers and GPU hardware supports them:
- Motion compensation (mocomp)
- Inverse discrete cosine transform (iDCT)
- In-loop deblocking filter
- Intra-frame prediction
- Variable-Length Decoding (VLD), more commonly known as slice-level acceleration
- Bitstream processing (CAVLC/CABAC)
