Upgrade from 1.18.0 to 1.19.0

toolbox has been replaced with toolbox_url

We replaced the toolbox variable with toolbox_url in our Terraform modules. The new variable is now a URL that must be accessible by the created servers. In addition to all URLs supported by pip install, it also supports URLs in the form of s3://bucket/path.

genvid.toolbox.NetworkTool.get_external_ip no longer support ipgetter

ipgetter has been removed from the PyPI Repository and so we have removed its support in the genvid.toolbox.NetworkTool. If you were setting the CHECKIP_URL to None, this option is no longer available. You can either leave it to its default valut of https://checkip.amazonaws.com or set it to other URL, like https://api.ipify.org/ if you prefer. The GENVID_CHECKIP_URL environment variable can now also be used to change the default value.

Improved Engine

Creating streams

We recommend creating the stream like this:

// We need a name to identify the stream.
const char *pSomeStreamName = "SomeStreamName";

// Create an entry for a stream.

// Set all the stream's parameters.

// At this point the first call to Genvid_Submit[DataType]
// should have all the necessary information to
// create the stream.

A new version stream only holds one type of data. For example once a stream is created as a video stream it is setup to handle video data and assumes that video data will be provided. Providing a type of data that a stream was not created to handle is undefined behavior.

Data submission

This new version smooths out data submission using time slots. It defines these slots when a stream is created then adheres strictly to them. If data is submitted faster than it was supposed to be, only the latest time code within a time slot width (1 / fps) will be accepted, previous ones will be dropped. If the data is not submitted as often as it was supposed to be, the last data submitted is sent again. If it’s an audio stream, silence is sent in place of the original audio.
