Hi,
The nvvidconv plugin supports the two kinds of conversions:
1. ... ! video/x-raw ! nvvidconv ! video/x-raw(memory:NVMM) ! ...
2. ... ! video/x-raw(memory:NVMM) ! nvvidconv ! video/x-raw ! ...
This case is not supported:
... ! video/x-raw ! nvvidconv ! video/x-raw ! ...
You may try this:
... ! video/x-raw ! nvvidconv ! video/x-raw(memory:NVMM) ! nvvidconv ! video/x-raw ! ...
However, it copies CPU buffers to NVMM buffers and then copy back to CPU buffers. Not sure if this brings performance improvement than using videoconvert plugin directly.
