Piped IO is required

[Klayflash]

Hello.

I like to use tool without storing temporary files for video transcoding. So, piped IO is required.

For example vmaf tool on Windows can be used like this:

D:\vmaf\2.3.0\vmaf.exe --reference \\.\pipe\Process_Pipe_20900_33_1121943890000000 --distorted \\.\pipe\Process_Pipe_20900_34_1121943890000000 --width 3840 --height 2160 --pixel_format 420 --bitdepth 8 --json --output R:\Temp\g3o8le0l.tmp\outFile

Or something like image2pipe from ffmpeg (see ffmpeg faq):

cat *.jpg | ffmpeg -f image2pipe -c:v mjpeg -i - output.mpg

Thanks!

We have no plans to implemented named pipe support into the FidelityFX CLI tool unfortunately, but we will happily review and accept a suitable patch from a contributor that implements it.

pipes/files can be read via fopen("filepath","rb") Just by replacing existing calls by these. Python example that accepts file or pipe for read:

        fh = open(name,"rb")
        actual = fh.read()

and for write:

        fh = open(name,"wb")
        fh.write(buf)
