We want to encode multi-stream camera videos at the same time.
Can we use the api NvMediaIEPBitsAvailable at different threads at the same time to do this?

Dear @liuq1,
NvMedia APIs are not thread safe. Please see

Thanks @SivaRamaKrishnaNV
But we can use a single encoder to encode multiple video streams simultaneously, right？
