NetGear_Async FAQs¶
What is NetGear_Async API and what does it do?¶
Answer: NetGear_Async is an asyncio videoframe messaging framework, built on zmq.asyncio
, and powered by high-performance asyncio event loop called uvloop
to achieve unmatchable high-speed and lag-free video streaming over the network with minimal resource constraints. Basically, this API is able to transfer thousands of frames in just a few seconds without causing any significant load on your system. For more info. see NetGear_Async doc ➶
How to get started with NetGear_Async API?¶
Answer: Answer: Answer: First, refer to the Switching from OpenCV guide, then go through NetGear_Async documentation ➶. If you still have doubts, ask us on Gitter ➶ Community channel.

"NetGear_Async is throwing ModuleNotFoundError
on importing", Why?¶
Answer: This error means, VidGear is installed WITHOUT asyncio package support on your machine. For this support, see Requirements ➶.
What is the key difference between NetGear_Async and NetGear APIs?¶
Answer:
-
NetGear: implements a high-level wrapper around PyZmQ python library that contains python bindings for ZeroMQ - a high-performance asynchronous distributed messaging library that provides a message queue, but unlike message-oriented middleware, its system can run without a dedicated message broker.
-
NetGear_Async: is an asyncio videoframe messaging framework, built on
zmq.asyncio
, and powered by high-performance asyncio event loop calleduvloop
to high-speed and lag-free video streaming over the network with minimal resource constraints.
Key Difference: NetGear_Async is highly memory efficient, but has less features as compared to NetGear API which is marginally faster too.
Can I use Multi-Server, Bi-Directional like modes in NetGear_Async?¶
Answer: No, NetGear_Async does NOT provide support for any NetGear's Exclusive modes yet.
How to use NetGear_Async with custom Server Source from OpenCV?¶
