lavc/vaapi_encode_h265: fix conf_win_xxx_offset for 4:2:2/4:4:4 encoding Use desc->log2_chroma_w/h to calculate the sps->conf_win_right/bottom_offset. Based on Table 6-1, SubWidthC and SubHeightC depend on chroma format(log2_chroma_w/h). Based on D-28 and D-29, set the correct cropped width/height. croppedWidth = pic_width_in_luma_samples − SubWidthC * ( conf_win_right_offset + conf_win_left_offset ); croppedHeight = pic_height_in_luma_samples − SubHeightC * ( conf_win_bottom_offset + conf_win_top_offset ); Signed-off-by: Linjie Fu <linjie...@intel.com> > http://git.videolan.org/gitweb.cgi/ffmpeg.git/?a=commit;h=2847c5c6f93b00c0ec9fb82dba7c382faf7335cc --- libavcodec/vaapi_encode_h265.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/libavcodec/vaapi_encode_h265.c b/libavcodec/vaapi_encode_h265.c index 538862a9d5..97dc5a7e75 100644 --- a/libavcodec/vaapi_encode_h265.c +++ b/libavcodec/vaapi_encode_h265.c @@ -410,10 +410,10 @@ static int vaapi_encode_h265_init_sequence_params(AVCodecContext *avctx) sps->conformance_window_flag = 1; sps->conf_win_left_offset = 0; sps->conf_win_right_offset = - (ctx->surface_width - avctx->width) / 2; + (ctx->surface_width - avctx->width) >> desc->log2_chroma_w; sps->conf_win_top_offset = 0; sps->conf_win_bottom_offset = - (ctx->surface_height - avctx->height) / 2; + (ctx->surface_height - avctx->height) >> desc->log2_chroma_h; } else { sps->conformance_window_flag = 0; } _______________________________________________ ffmpeg-cvslog mailing list ffmpeg-cvslog@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-cvslog To unsubscribe, visit link above, or email ffmpeg-cvslog-requ...@ffmpeg.org with subject "unsubscribe".
