Hello there!

I am using a custom version of a deepstream pipeline, nearly identical to deepstream_test3_app. In the custom plugin gst-dsexample I want to allocate more space on the incoming NvBufSurface. How can I expand the size there? Can I use another plugin before gst-dsexample to increase the surface size?

Thx in advance,
Tobi

No. The dsexample plugin is the in-place plugin, the input buffer is the output buffer, you can not change the buffer size.

If you want to output a larger video (enlarge the video resolution), you can use nvvideoconvert before dsexample.
