This patch add g/s_selection for MT8173 V4L2 Encoder. Only output queue support g/s_selection to configure crop. The top/left of active rectangle should always be (0,0)
Signed-off-by: Tiffany Lin <[email protected]> --- v6: - remove unused err variable from s_selection v5: - remove visible_height change to a separate patch v4: - do not return -ERANGE and just select a rectangle that works with the hardware and is closest to the requested rectangle - refine v3 note about remove visible_height modification in s_fmt_out v3: - add v4l2_s_selection to check constraint flags - remove visible_height modification in s_fmt_out, it will make v4l2-compliance test Cropping fail becuase visible_height larger than coded_height. --- drivers/media/platform/mtk-vcodec/mtk_vcodec_enc.c | 66 ++++++++++++++++++++ 1 file changed, 66 insertions(+) diff --git a/drivers/media/platform/mtk-vcodec/mtk_vcodec_enc.c b/drivers/media/platform/mtk-vcodec/mtk_vcodec_enc.c index 3ed3f2d..b1f0acb 100644 --- a/drivers/media/platform/mtk-vcodec/mtk_vcodec_enc.c +++ b/drivers/media/platform/mtk-vcodec/mtk_vcodec_enc.c @@ -631,6 +631,69 @@ static int vidioc_try_fmt_vid_out_mplane(struct file *file, void *priv, return vidioc_try_fmt(f, fmt); } +static int vidioc_venc_g_selection(struct file *file, void *priv, + struct v4l2_selection *s) +{ + struct mtk_vcodec_ctx *ctx = fh_to_ctx(priv); + struct mtk_q_data *q_data; + + if (s->type != V4L2_BUF_TYPE_VIDEO_OUTPUT) + return -EINVAL; + + q_data = mtk_venc_get_q_data(ctx, s->type); + if (!q_data) + return -EINVAL; + + switch (s->target) { + case V4L2_SEL_TGT_CROP_DEFAULT: + case V4L2_SEL_TGT_CROP_BOUNDS: + s->r.top = 0; + s->r.left = 0; + s->r.width = q_data->coded_width; + s->r.height = q_data->coded_height; + break; + case V4L2_SEL_TGT_CROP: + s->r.top = 0; + s->r.left = 0; + s->r.width = q_data->visible_width; + s->r.height = q_data->visible_height; + break; + default: + return -EINVAL; + } + + return 0; +} + +static int vidioc_venc_s_selection(struct file *file, void *priv, + struct v4l2_selection *s) +{ + struct mtk_vcodec_ctx *ctx = fh_to_ctx(priv); + struct mtk_q_data *q_data; + + if (s->type != V4L2_BUF_TYPE_VIDEO_OUTPUT) + return -EINVAL; + + q_data = mtk_venc_get_q_data(ctx, s->type); + if (!q_data) + return -EINVAL; + + switch (s->target) { + case V4L2_SEL_TGT_CROP: + /* Only support crop from (0,0) */ + s->r.top = 0; + s->r.left = 0; + s->r.width = min(s->r.width, q_data->coded_width); + s->r.height = min(s->r.height, q_data->coded_height); + q_data->visible_width = s->r.width; + q_data->visible_height = s->r.height; + break; + default: + return -EINVAL; + } + return 0; +} + static int vidioc_venc_qbuf(struct file *file, void *priv, struct v4l2_buffer *buf) { @@ -689,6 +752,9 @@ const struct v4l2_ioctl_ops mtk_venc_ioctl_ops = { .vidioc_create_bufs = v4l2_m2m_ioctl_create_bufs, .vidioc_prepare_buf = v4l2_m2m_ioctl_prepare_buf, + + .vidioc_g_selection = vidioc_venc_g_selection, + .vidioc_s_selection = vidioc_venc_s_selection, }; static int vb2ops_venc_queue_setup(struct vb2_queue *vq, -- 1.7.9.5
