Description:
timedcapture 0.3.2
timedcapture
a cython-based module to achieve on-time video capture through V4L2.
For a general usage, refer to USAGE.
Prerequisites
IMPORTANT NOTE: the current implementation only allows 16-bit grayscale acquisition.
IMPORTANT NOTE: there is no functionality that controls the frame rate. Frame-capture timings must be controlled elsewhere, either using software or hardware timers.
The library is tested on Ubuntu 18.04 LTS, but it is supposed to work on any Linux environment that runs V4L2.
Please note that the library is optimized for cameras from ImagingSource.
By using devices from other manufacturers, you will not have control over functionalities such as:
1 microsecond-order exposure control (V4L2 only allows the order of 10 microseconds)
auto-gain/manual-gain switch (the gain control will be totally manual- or auto-controlled)
trigger modes (by default, only the free-running mode will be allowed)
"strobe" output
These settings must be configured elsewhere.
Installation
For the time being, we only provide the source distribution on PyPI.
You will need a working Cython and Numpy combination pre-installed.
$ pip install numpy>=1.19 cython>=0.29 # or: "conda install numpy cython", in case you use Anaconda
$ pip install timedcapture
