The FFmpeg subprocess call uses user-provided video_path directly in the command arguments without validation. If video_path comes from user input (e.g., environment variables or API parameters), it should be validated to ensure it doesn't contain path traversal attacks or other malicious inputs. Consider validating that the path exists, is a file, and doesn't escape expected directories.

The FREE_TIER_LIMIT_MB default of 500MB may be too low for Railway's free tier, which provides 512MB. Consider increasing the default to 512MB to align with Railway's actual free tier limit and avoid premature shutdowns.

The maintenance mode badge uses an emoji (🔧) which may not be announced consistently by screen readers. Consider adding aria-label="Maintenance Mode" to the status badge element or using text-based alternatives alongside emojis.

Including both ffmpeg and ffmpeg-full is redundant and will increase build size/time unnecessarily. ffmpeg-full includes all features of the base ffmpeg package. Consider removing the ffmpeg entry and keeping only ffmpeg-full.

There was a problem hiding this comment.
The error message "Input video not found" could be more helpful by suggesting next steps. Consider adding information about where the application expects the video file or how to provide one (e.g., "Please ensure input_video.mp4 exists in the working directory, or set VIDEO_INPUT_PATH environment variable to specify a different path").
| print(f"❌ Input video not found: {input_video}") | |
| print("Please provide a video file to process.") | |

| "Please ensure the video file exists at the specified path.\n" | |

Using ast.literal_eval() to parse the API response is risky because it expects Python literal syntax, but the API returns JSON. If the API response contains JSON-specific syntax (like null, true, false instead of None, True, False), this will fail. Use json.loads() instead for proper JSON parsing.

The [railway], [railway.optimization], and [railway.maintenance] sections are not standard Railway configuration syntax. Railway primarily uses [build] and [deploy] sections. These custom sections will be ignored by Railway and may cause confusion. Consider removing these or documenting them as informational metadata only.

FFmpeg is being called to extract audio, but the output format is specified as "mp3" while the filename is "temp_audio.wav". This mismatch between file extension and format may cause issues. Either change the format parameter to match the extension (-f wav) or change the filename to temp_audio.mp3.

The memory usage check uses psutil.Process(os.getpid()).memory_info().rss which only measures the current process's memory. However, the application may spawn child processes (FFmpeg, Whisper model loading) that consume significant memory beyond the parent process. Consider using psutil.virtual_memory() to check system-wide memory usage or tracking child processes explicitly.
