Clarification about generation on Windows

[ksze]

Can you provide more clarifications about running python generate.py on Windows?

First of all, it appears that you can't use Python 2.7 from Cygwin (64-bit), as it doesn't know about WindowsError and results in a name error.

Second of all, can I use MinGW-w64? If so, what installation option should I use?

• Threads: posix or win32?
• Exceptions: seh or sjlj?

As for MinGW - only basic gcc is needed the rest is by default as it not suppose to compile anything.
After generation some minor tweaks are needed in FFmpegInvoke.cs in order to compile it.
