Please provide complete information as applicable to your setup.

try to query nvdcf tracker as following:
NvMOTQuery query;
NvMOT_Query(mtrackerConfigFile.size(), const_cast<char *>(mtrackerConfigFile.c_str()), &query);

mtrackerConfigFile shows below:

print the query info as following:
{computeConfig = 1 ‘\001’, numTransforms = 1 ‘\001’, colorFormats = {NVBUF_COLOR_FORMAT_NV12, 1431709388, 21845, 4294958992},
memType = NVBUF_MEM_CUDA_DEVICE, supportBatchProcessing = true, supportPastFrame = true}

I am confused with the colorFormats, as the Gst-nvtracker docs shows that the nvdcf tracker supports RGBA and NV12, but actually it only support NV12. so how to support the RGBA formats?
I am refering to DCF Tracker REFUSING to work while using low level library - #4 by moezruo6 and KLT NvMOT usage to test the nvdcf tracker. and got this:
!![Exception] [FAILED] Invalid color format
An exception occurred. [FAILED] Invalid color format
terminate called after throwing an instance of ‘std::exception’
what(): std::exception

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.

Hey, you are using a standalone app to test nvdcf tracker lib, right? can you share me the repro for how to replicate your issue?
