Author: Anton Khirnov <[email protected]> Committer: Anton Khirnov <[email protected]> Date: Sat Jan 7 21:06:16 2017 +0100 qsvdec: do not sync PIX_FMT_QSV surfaces Introducing enforced sync points in arbitrary places is bad for performance. Since the vast majority of receiving code (QSV VPP or encoders, retrieving frames through hwcontext) will do the syncing, this change should not be visible to most callers. But bumping micro just in case. This is also consistent with what VAAPI hwaccel does. --- libavcodec/qsvdec.c | 8 +++++--- libavcodec/version.h | 2 +- 2 files changed, 6 insertions(+), 4 deletions(-) diff --git a/libavcodec/qsvdec.c b/libavcodec/qsvdec.c index b83b0fc..0cbe509 100644 --- a/libavcodec/qsvdec.c +++ b/libavcodec/qsvdec.c @@ -363,9 +363,11 @@ static int qsv_decode(AVCodecContext *avctx, QSVContext *q, av_fifo_generic_read(q->async_fifo, &sync, sizeof(sync), NULL); out_frame->queued = 0; - do { - ret = MFXVideoCORE_SyncOperation(q->session, *sync, 1000); - } while (ret == MFX_WRN_IN_EXECUTION); + if (avctx->pix_fmt != AV_PIX_FMT_QSV) { + do { + ret = MFXVideoCORE_SyncOperation(q->session, *sync, 1000); + } while (ret == MFX_WRN_IN_EXECUTION); + } av_freep(&sync); diff --git a/libavcodec/version.h b/libavcodec/version.h index 7348a0c..106543d 100644 --- a/libavcodec/version.h +++ b/libavcodec/version.h @@ -29,7 +29,7 @@ #define LIBAVCODEC_VERSION_MAJOR 57 #define LIBAVCODEC_VERSION_MINOR 30 -#define LIBAVCODEC_VERSION_MICRO 3 +#define LIBAVCODEC_VERSION_MICRO 4 #define LIBAVCODEC_VERSION_INT AV_VERSION_INT(LIBAVCODEC_VERSION_MAJOR, \ LIBAVCODEC_VERSION_MINOR, \ _______________________________________________ libav-commits mailing list [email protected] https://lists.libav.org/mailman/listinfo/libav-commits
