From: Lynne <dev@lynne.ee> To: ffmpeg-devel@ffmpeg.org Cc: Lynne <dev@lynne.ee> Subject: [FFmpeg-devel] [PATCH] av1dec: update hwaccel decode_params on AV1_OBU_SEQUENCE_HEADER Date: Fri, 14 Mar 2025 12:47:44 +0100 Message-ID: <20250314114749.55174-1-dev@lynne.ee> (raw) Previously, the callback was only called on init. This makes it get called on every frame. We should switch to VK_KHR_video_maintenance2 and provide all params upfront, but almost nothing supports it yet. --- libavcodec/av1dec.c | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/libavcodec/av1dec.c b/libavcodec/av1dec.c index baa9dea0f7..ed00278ed3 100644 --- a/libavcodec/av1dec.c +++ b/libavcodec/av1dec.c @@ -1329,6 +1329,15 @@ static int av1_receive_frame_internal(AVCodecContext *avctx, AVFrame *frame) s->pix_fmt = AV_PIX_FMT_NONE; + if (FF_HW_HAS_CB(avctx, decode_params)) { + ret = FF_HW_CALL(avctx, decode_params, AV1_OBU_SEQUENCE_HEADER, + s->seq_data_ref->data, s->seq_data_ref->size); + if (ret < 0) { + av_log(avctx, AV_LOG_ERROR, "HW accel decode params fail.\n"); + return ret; + } + } + break; case AV1_OBU_REDUNDANT_FRAME_HEADER: if (s->raw_frame_header) -- 2.47.2 _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-request@ffmpeg.org with subject "unsubscribe".
