From cedc12108b55d0c571da883a4083977af612dcce Mon Sep 17 00:00:00 2001 From: Wu-Cheng Li Date: Tue, 19 Jan 2016 05:07:09 -0200 Subject: [media] v4l: add V4L2_CID_MPEG_VIDEO_FORCE_KEY_FRAME Some drivers also need a control like V4L2_CID_MPEG_MFC51_VIDEO_FORCE_FRAME_TYPE to force an encoder key frame. Add a general V4L2_CID_MPEG_VIDEO_FORCE_KEY_FRAME so the new drivers and applications can use it.
