I have a pipeline like this:
srcs -> nvstreammux -> nvinfer -> nvtracker -> nvvideoconvert(1) -> capsfilter(1) -> nvmultistreamtiler -> nvvideoconvert(2) -> nvdsosd -> tee -> sinks

  • When capsfilter(1) is set to "video/x-raw(memory:NVMM),format=RGBA"
    • setting tiler show-source to any value != -1 makes the display black instead of showing the respective source.
    • setting tiler show-source back to -1 then all sources are tiled and displayed normally.
  • When capsfilter(1) is left empty, then tiler show-source works as expected but the problem is that in this case images can’t be extracted from buffer probe on nvvideoconvert(1), because pyds.get_nvds_buf_surface works only with RGBA.

Hey customer,
We will fix the issue on next release, thanks for reporting.
