Description

Describe the bug
I have problem to run cmd command with Subprocess. I tried to run ffmpeg on python with Subprocess. I have problem to run on Claude desktop because it's take too long. I run ffmpeg script under 5 seconds for normal trim video, but it's like took forever on Claude desktop. I tried to run ffmpeg from external library or external file or script, it doesn't work, I think it's just Subprocess that have problem with MCP.
