From 91ae0e1ec6ec91cd297933886b424f9a4a8acbd4 Mon Sep 17 00:00:00 2001 From: Tiffany Lin Date: Mon, 15 Aug 2016 00:08:03 -0300 Subject: [PATCH] [media] vcodec:mediatek: Fix visible_height larger than coded_height issue in s_fmt_out The original code add extra 32 line to visible_height. It is incorrect, 32 line should be add to coded_height. The purpose is that user space could calcuate real buffer size needed by using coded_width * coded_height. But this method will make v4l2-compliance test fail, since g_fmt != s_fmt(g_fmt) So remove extend visible_height or coded_height, user space should just use sizeimage to get real buffer size needed Signed-off-by: Tiffany Lin Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab --- drivers/media/platform/mtk-vcodec/mtk_vcodec_enc.c | 10 ---------- 1 file changed, 10 deletions(-) diff --git a/drivers/media/platform/mtk-vcodec/mtk_vcodec_enc.c b/drivers/media/platform/mtk-vcodec/mtk_vcodec_enc.c index 3b0691f2deb4..9b0187ecfa6a 100644 --- a/drivers/media/platform/mtk-vcodec/mtk_vcodec_enc.c +++ b/drivers/media/platform/mtk-vcodec/mtk_vcodec_enc.c @@ -487,7 +487,6 @@ static int vidioc_venc_s_fmt_out(struct file *file, void *priv, struct mtk_q_data *q_data; int ret, i; struct mtk_video_fmt *fmt; - unsigned int pitch_w_div16; struct v4l2_pix_format_mplane *pix_fmt_mp = &f->fmt.pix_mp; vq = v4l2_m2m_get_vq(ctx->m2m_ctx, f->type); @@ -530,15 +529,6 @@ static int vidioc_venc_s_fmt_out(struct file *file, void *priv, q_data->coded_width = f->fmt.pix_mp.width; q_data->coded_height = f->fmt.pix_mp.height; - pitch_w_div16 = DIV_ROUND_UP(q_data->visible_width, 16); - if (pitch_w_div16 % 8 != 0) { - /* Adjust returned width/height, so application could correctly - * allocate hw required memory - */ - q_data->visible_height += 32; - vidioc_try_fmt(f, q_data->fmt); - } - q_data->field = f->fmt.pix_mp.field; ctx->colorspace = f->fmt.pix_mp.colorspace; ctx->ycbcr_enc = f->fmt.pix_mp.ycbcr_enc; -- 2.20.1
