[FFmpeg-devel] [PATCH] tools/cws2fws.c tweaks

[James Darnley]

Is this tool still supported?

I was trying to use this tool on Windows but it repeatedly failed.  I
discovered this was because it doesn't open the file in binary mode.
A simple binary or with O_BINARY solved that.

Then I saw that it was not interpreting the size correctly, reading
the input as signed chars.  It managed to interpret hex(46 BD 0B 00)
as -17086.  Changing them to unsigned chars fixed that.

I've attached a diff which has these changes.
