#Summary
This Merge Request adds a mechanism to generate unique filenames for FFmpeg conversions in whisper_server.cpp. Previously, a single fixed filename was used (e.g., whisper-server-tmp.wav), which could result in unexpected file overwrites under certain circumstances. By generating a unique filename per request, any risk of overwriting temporary files is eliminated.
#Background / Motivation
• Problem: Relying on a static filename for temporary audio files may lead to overwrites if multiple operations occur simultaneously or if the same file name is reused.
• Goal: Dynamically generate unique filenames, ensuring each request or operation uses an isolated temporary file.
