Set drop frame interval with video decoder?
For nvtracker, please refer to Deepstream Tracker FAQ - Intelligent Video Analytics / DeepStream SDK - NVIDIA Developer Forums for tuning . Maybe you can try to set “probationAge” to a very small value(maybe zero).
There is video encoding and decoding performance data in Video Codec SDK | NVIDIA Developer such as
Only some Data Center GPU are in the graph, but the nvdec hardware is the same as the other GPUs(E.G Geforce GPUs).
Take Geforce RTX 3090 as the example, you can get the NVDEC family and generation information in Video Encode and Decode GPU Support Matrix | NVIDIA Developer, it is Ampere 5th generation, 1 core in RTX 3090. The A10 GPU also has 2 Ampere 5th generation NVDEC cores. So the RTX 3090 NVDEC capability is the half of A10 GPU.
Back to Video Codec SDK | NVIDIA Developer, you can find the A10 support 37 1080p@30fps H264 streams OR 81 1080p@30fps HEVC streams. So the RTX 3090 can support 37/2=18 1080p@30fps H264 streams OR 81/2=40 1080p@30fps HEVC streams.
