    omxh26xdec: videodecoder support subframe · aa99c538
    Nicolas Dufresne authored
    Use of subframe API from videodecoder base class.
    This subframe allows to decode subframe instead of
    waiting for a whole frame.
    The subframe uses the same frame over the whole
    subframe passing process and will wait
    for a signal to know the last subframe.
    In this implementation it will use
    GST_VIDEO_BUFFER_FLAG_MARKER as the
    end of batch of subframes.
    
    This implement subframe mode negotation for the Zynq based on caps
    negotation. This mode can be combined with low-latency mode, in order to
    reach the lowest possible latency (assuming the stream is within the
    low-latency constraints for the HW).
