  1. I wrapped ldc operator to do LDC for my camera image data
  2. create 7 ldc opeators as each independence thread for 7 cameras
  3. the first ldc operator could not work as expected,the other 6 work well.
  4. all ldc operator work steps as:
    a. NvMediaDeviceCreate
    b. NvMediaLDCCreateNew
    c. NvMediaLDCMappingGen
    d. NvMediaLDCProcess

my question:

  1. could the NvMediaLDC moudle work as multi thread?
  2. if there any specific work sequence need?
  3. or other work points igored?
