From: Haihao Xiang <haihao.xi...@intel.com> In oneVPL, a valid mfxLoader handle is needed when creating mfx session for decoding, encoding and processing[1], so add loader field to AVQSVDeviceContext. User should fill this field before calling av_hwdevice_ctx_init() if using oneVPL
This is in preparation for oneVPL support [1]https://spec.oneapi.io/versions/latest/elements/oneVPL/source/programming_guide/VPL_prg_session.html#onevpl-dispatcher --- doc/APIchanges | 3 +++ libavutil/hwcontext_qsv.h | 11 +++++++++++ libavutil/version.h | 2 +- 3 files changed, 15 insertions(+), 1 deletion(-) diff --git a/doc/APIchanges b/doc/APIchanges index 20b944933a..1672aa0321 100644 --- a/doc/APIchanges +++ b/doc/APIchanges @@ -14,6 +14,9 @@ libavutil: 2021-04-27 API changes, most recent first: +2022-07-05 - xxxxxxxxxx - lavu 57.28.100 - hwcontext_qsv.h + Add loader field to AVQSVDeviceContext + 2022-06-12 - xxxxxxxxxx - lavf 59.25.100 - avio.h Add avio_vprintf(), similar to avio_printf() but allow to use it from within a function taking a variable argument list as input. diff --git a/libavutil/hwcontext_qsv.h b/libavutil/hwcontext_qsv.h index 42e34d0dda..e2dba8ad83 100644 --- a/libavutil/hwcontext_qsv.h +++ b/libavutil/hwcontext_qsv.h @@ -34,6 +34,17 @@ */ typedef struct AVQSVDeviceContext { mfxSession session; + /** + * The mfxLoader handle used for mfxSession creation + * + * This field is only available for oneVPL user.
