Here you configure a pipeline that ends at ipu1 prpenc capture ...

... which is /dev/video0 ...
[...] > - entity 27: ipu1_ic_prpvf capture (1 pad, 1 link) > type Node subtype V4L flags 0 > device node name /dev/video1
... not /dev/video1 ...

... and then you try to capture from prpvf, which is not part of a configured pipeline.
