Expose MppFrameStatus to the mpp_frame.h #425

Open hbiyik opened 1 year ago

hbiyik commented 1 year ago

This is a feature request.

After the frame is decoded, there are people who are interested in the frame type. IE: P, I or B frame. I see this information is already a part MppFrameStatus which is a part of MppFrame, but is not exposed to mpp_frame.h

is it possible to add somehting MppFrameStatus* mpp_frame_get_status(const MppFrame frame);

to the file: https://github.com/rockchip-linux/mpp/blob/e34f0dd1520181eda061f91883c670504432fb8f/inc/mpp_frame.h#L422

using MPP_FRAME_ACCESSORS?

The MppFrame may not be the decoded frame for it will pass the iep deinterlace flow. Then the frame rate may change and frame I, P, B type will not be accurate. The MppFrameStatus is used mainly in encoder part.

Whatever it's called internally, might it be possible that decoder reports frame type in any way? Like most (if not all) decoders actually.

It is possible to do so.
