NVCSI supports the Predictor-1 DPCM compression as stated in the Xaxier TRM (DP-09253-002_v1.3p) page 630.
But this chapter also states that the software needs to override the data type to let the color parser know how to unpack it from byte to pixel and then send to the DPCM decompression unit.
We are using Jetpack v4.2.3 with the L4T release 32.2.3.
Is this software part handled by your drivers in this jetpack version ?
Do you confirm that the DPCM ratios are well supported by your drivers and the MIPI frames are recognized and decompressed ?
