Hi,

Are there any reference sample sets available for GY/T 299.1-2016 aka
IEEE 1857.4 aka AVS2?

I tried to search around and while I found some info that 92 samples
were available on some semi-closed FTP, I couldn't really find any
real test samples that could make a reference test suite.

Best regards,
Jan
