Calling a commandline program using subprocess without cluttering console with shell, possible?
I am having difficulty running subprocess in python 3, to user handbrakeCLI to extract a specified length of video to a new file. The code itself works wonderfully, but it prints the output to console. I do not need to see hundreds of lines of encode information.
From my limited knowledge of this module, shell=True is the option which prints to console. Remove it or change to =False and it fails with a "[WinError2] System cannot locate specified file"
This runs inside of a tkinter program, but accesses nothing outside itself, so this is the entire code that prints the output to console.
filepath = askopenfilename()
filepathSplit = filepath.split("/")
location = "\".join(filepathSplit[:-1]) + "\"
inputFileName = os.path.splitext(filepathSplit[len(filepathSplit)-1])[0]
inputFileType = os.path.splitext(filepath)[1]
outputFile = inputFileName + " -1" + inputFileType
# print(filepath)
# print(f"Location: {location}")
# print(f"input filename: {inputFileName}")
# print(f"input filetype: {inputFileType}")
# print(f"output filename: {outputFile}")
startTime = 0
endTime = 2
subprocess.call(f'HandbrakeCLI.exe -i "{filepath}" -o "{location + outputFile}" --start-at duration:{startTime} --stop-at duration:{endTime}', cwd="C:\Program Files\HandBrake", shell=True)
print("It's finished, run the rest.")
It works perfectly when it's shell=True and prints eeeeverything to console, but fails when trying to avoid cluttering the console. Is this possible?
