gstreamer version: 1.16.3

R35 (release), REVISION: 1.0, GCID: 31346300, BOARD: t186ref, EABI: aarch64, DATE: Thu Aug 25 18:41:45 UTC 2022

I use nvv4l2decoder to decode gdr h264 data. When I switch the source data ， the resolution will change and the following error will be reported.

nvbufsurface: NvBufSurfaceCopy: buffer size mismatch
nvbufsurface: NvBufSurfaceCopy: failed to copy

I want to know how to solve it, looking forward to reply。

Hi,
We suggest upgrade to latest Jetpack 5.1.2(r35.4.1) and apply this patch for decoding GDR stream:
Jetson/L4T/r35.4.x patches - eLinux.org

[gstreamer]cannot decode H264/H265 GDR stream

Please give it a try.
