The advantage of binding between Surface and Context.

by Hirokazu Honda

Hi, According to libva document (http://01org.github.io/libva_staging_doxygen/group__api__core.html#ga4af3...), Surfaces are bound to a context if passing them as an argument when creating the context. Seeing intel-vaapi-driver code, the surfaces are just stored in object_context.render_targets. A surface processed by vaBeginPicture()-vaRenderPicture()-vaEndPicture() are specified in vaBeginPicture(). (object_context.current_render_target) It looks like a surface can be processed using a context by being specified in vaBeginPicture(), even if it is not bound to the context. Here, my questions are below. What is the advantage of binding? In what circumstances do we need to associate the context with surfaces? In which scenarios passing surfaces to vaCreateContext is required, and in which it is not? Best Regards, Hirokazu Honda

by Xiang, Haihao

Hi all, I'm pleased to announce the 2.0.0 release of libva, the implementation of Video Acceleration API (VA-API). Highlights: * Bump VA-API version to 1.0.0 and libva to 2.0.0 * Add new API for H264 FEI support * Add definition of VA_FOURCC_I420 * Add functions for converting common enums to strings * Deprecate H.264 baseline profile and FMO support * Deprecate packed misc packed header flag * Delete libva-tpi and libva-egl backends * Refine VASliceParameterBufferHEVC, VAEncMiscParameterBuffer * Fix errors in VAConfigAttribValEncROI, VAEncMacroblockParameterBufferH264 * Fix race condition in wayland support * Rename vaMessageCallback to VAMessageCallback * Make logging callbacks library-safe Note libva 2.0.0 is not compatible with the old version of libva, but for most user, what you need to do is to rebuild your VA-API based application against libva 2.0.0. Thanks to everybody who contributed to this release! git tag: 2.0.0 tarball: https://github.com/01org/libva/releases/download/2.0.0/libva-2.0.0.tar.bz2 sha1sum: 762a49f8925ca1d0531c5071afbd629ffea93b90 libva-2.0.0.tar.bz2 Thanks Haihao

Questions on configuration for iHD driver.

by Paul Knopf

My company is using a Yocto solution (pyro) that is using meta-intel. By default, it is using the i965 driver/vaapi. I need to switch to using iHD for the added throughput, so that we can achieve 4k60fps. I have followed Intel's guidance here: https://software.intel.com/en-us/media-sdk/choose-download/embedded-iot However, it is for jethro (older version of Yocto). With that said, I need to find out which configuration (libraries) I should update in my pyro solution to properly support the iHD driver. I am finding little guidance on how to build a custom configuration that supports iHD. There is just so many different repors/forks/versions/dependencies, and little documentation. I am using an i7 6th gen CPU (as 7th gen apparently isn't support by iHD). My assumptions currently are: - I must use a specific kernel. The supported jethro example uses 4.1. Is this correct? Is it possible to use the 4.9 version supplied by meta-intel? - I need to use the github.com/iotg-lin-gfx-* family of repositories. This includes - iotg-lin-gfx-mesa - iotg-lin-gfx-libva - iotg-lin-gfx-libdrm Each of this repos contain an "m3" branch. How does this branch relate to the iHD driver provided by intel? I'd like to use the R2.1 deliverable of the msdk. Another question, what is the iotg-lin-gfx-va-driver used for? It is fork of the i965 driver? If so, why the fork? Attached are my notes which details each configuration (supported jethro and custom pyro). Any help is greatly appreciated. I am currently lost in the ocean of forks and versions! :)
