FFMPEG error with Python Popen on Windows 10
When using Popen
to execute FFMPEG commands in Python on Windows 10, you may encounter an error related to the ffmpeg
command not being recognized. This can happen because the FFMPEG executable may not be in the system's PATH environment variable.
To resolve this issue, you can provide the full path to the FFMPEG executable in the Popen
command. Here's an example:
pythonimport subprocess
ffmpeg_path = r'C:\path\to\ffmpeg.exe'
command = [ffmpeg_path, '-i', 'input.mp4', 'output.mp4']
process = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
stdout, stderr = process.communicate()
if process.returncode == 0:
print('FFMPEG command executed successfully.')
else:
print('FFMPEG command failed with error:', stderr.decode('utf-8'))
In the above example, ffmpeg_path
variable contains the full path to the FFMPEG executable. The command list specifies the FFMPEG command-line arguments, where input.mp4
is the input file and output.mp4
is the output file.
By providing the full path to the FFMPEG executable, you can ensure that the command is executed correctly. Make sure to replace C:\path\to\ffmpeg.exe
with the actual path to your FFMPEG executable.
Additionally, ensure that you have FFMPEG installed on your system and the executable is located at the specified path.
