The NVDS Analytics plugin generally support two lines for directional virtual line crossing detection in a stream. The config file sample shows 2 lines defined as line-crossing-Entry and line-crossing-Exit as follows:
[line-crossing-stream-0] enable=1 line-crossing-Entry=1072;911;1143;1058;944;1020;1297;1020; line-crossing-Exit=789;672;1084;900;851;773;1203;732 class-id=0 extended=0 mode=loose
But my application case requires more than two lines (4 lines) to be custom defined. I have searched the plugin documentation but found no such information about the configuration. The libnvds_dsanalytics.so is prebuilt and not customize-able. However, is there any way to customize 4 lines for line crossing detection?
