Board size
development environment
We have cross-compiled common third-party libraries and placed them in the virtual machine, which is convenient for users to develop and use.
open source software
In order to demonstrate the basic capabilities of the evaluation board and make it easier for users to fully evaluate the solution before starting development, we have produced an "encoder system" that displays all the interface capabilities and encoding and decoding performance of the solution in the form of a general-purpose encoder. The product is completely open source, including the main program source code, file system, web page source code, etc.
If the user's target product is similar to the open source product, it can be modified directly on the basis of the source code of the product.
