I want to encode a stream (1280*800) with gstreamer lossless mode.

[encode_multi_app_node-1] NVMAP_IOC_READ:1077431815 failed [22]
[encode_multi_app_node-1] [1077431815]: Offset 2465792 SrcStride 7570 pDst 0xffff71754df8 DstStride 7570 Count 1
[encode_multi_app_node-1] NVMAP_IOC_WRITE:1077431814 failed [22]

This is probably a driver bug.

2465792 + 7570 = 2473362

Hi,
It looks like the resolution is not supported. Please share the steps to replicate the issue. We can check and confirm it.

Hi, can you reproduce my problem?

Hi,
We try this with 1280x800 on r36.3 and don’t hit the issue:
Can not decode H265 lossless - #3 by DaneLLL

The function looks good. Please give it a try.
