Between the published points (class D)
Camera profiles NVIDIA does not print are estimated by comparing the pixel rate against the rated 690 MP/s: max streams = ⌊690 ÷ (width × height × fps ÷ 10⁶)⌋. These are EdgeAIStack numbers, not NVIDIA's; they assume roughly linear NVDEC throughput inside the published range and are not asserted outside it. Rows that coincide with a published point show the datasheet count instead.

Power mode
NVDEC/NVENC maximum clock is the same in every nvpmodel power preset on Orin, so decode capacity does not change with the power mode.

Encode
Jetson Orin Nano (8GB / 4GB) has no hardware encoder (NVENC). The datasheet states: “1080p30 Supported via CPU Cores with Software”. Re-encoding or restreaming competes with inference for CPU cores; record camera streams as-is (passthrough) wherever possible.

What these numbers do and do not cover
- Hardware limit, not software. JetPack, DeepStream, GStreamer or Frigate may cap concurrent decoder sessions below the datasheet count.
- Decode in isolation. Simultaneous NVENC use shares memory bandwidth; expect real decode + encode totals below the sum of the two tables.
- Profile and chroma. Counts are for Main, Main10 at 8-bit 4:2:0; 4:4:4 halves throughput (datasheet note); Main10 shares the row.
- Decode is rarely the bottleneck. Inference, memory and preprocessing usually fail first on a detection pipeline; run the full pipeline check for your workload.
- Method. Formulas, evidence classes and the confidence rule are on the methodology page.
