Cannot input huge files

$ x265.exe "N:/Noel_98.yuv" -o "N:/Noel_98.hevc" --input-res 720x576 --fps 50
x265 [error]: unable to open input file <N:/Noel_98.yuv>

The above yuv file is 109 GB. Files of up to some hundred of MBs encode ok.

$ x265.exe "N:/Essai.yuv" -o "N:/Essai.hevc" --input-res 720x576 --fps 50

When you get this error: x265 [error]: unable to open input file <N:/Noel_98.yuv> without any other messages it essentially means fopen() is failing.

This looks like a 32bit MinGW issue. You can try this workaround:

x265 - -o "N:/Noel_98.hevc" --input-res 720x576 --fps 50 < "N:/Noel_98.yuv"

This makes the shell open the file and provide an open file handle as stdin.

Or you can build x265 as 64bit and this problem should go away.

Thanks - also for the great job you are doing. x265 is my first compile - a bit more fun than 'hello world'. I have changed from MinGW to MinGW-w64 which has 'long files support' even for 32-bit it seems, since it works now.

MinGW has no 'large file support'
