Those patches add end of stream handling for s5p-mfc encoder. The first patch was sent already to the list as RFC, but the discussion ended without any decision. This patch adds new v4l2_buffer flag V4L2_BUF_FLAG_EOS. Below short description of this change. s5p_mfc is a mem-to-mem MPEG/H263/H264 encoder and it requires that the last incoming frame must be processed differently, it means the information about the end of the stream driver should receive NOT LATER than the last V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE buffer. Common practice of sending empty buffer to indicate end-of-stream do not work in such case. Setting V4L2_BUF_FLAG_EOS flag for the last V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE buffer seems to be the most straightforward solution here. V4L2_BUF_FLAG_EOS flag should be used by application if driver requires it and it should be set only on V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE buffers. The second patch implements end-of-stream handling in s5p-mfc.
