    For the folllwing example, I am just trying to stream to a fakesink,
    toward the bottom, there are a couple errors ''Failed to allocate
    required memory' and 'Buffer pool activation failed'.

    I configured the pipeline as follows:
    media-ctl -l "'ov5640 2-0010':0 -> 'imx6-mipi-csi2':0[1]"
    media-ctl -l "'imx6-mipi-csi2':2 -> 'ipu1_csi1':0[1]"
    media-ctl -l "'ipu1_csi1':1 -> 'ipu1_ic_prp':0[1]"
    media-ctl -l "'ipu1_ic_prp':1 -> 'ipu1_ic_prpenc':0[1]"
    media-ctl -l "'ipu1_ic_prpenc':1 -> 'ipu1_ic_prpenc capture':0[1]"

    I am hoping I am doing this correctly.
