A common protocol structure is to have a header containing a length field, followed by data of length bytes, followed by additional protocol fields such as a CRC. If the length field is variable, the position of subsequent URH-specified protocol fields defined by fixed position will not be in the correct location.

I do not know the best way to address this, but quick and easy way to support

On the website there is a list of things to do. Some of them are easy, some are hard and long, and some are boring. Feel free to do something that is not in the list too.

I made this issue so people visiting this GitHub can see it. For more information just ask without obligation/compromise.
