# Media Processing Pipeline
[](https://github.com/pulkitpareek18/media-processing-pipeline/actions/workflows/ci.yml)
## Release Snapshot (March 2026)
- Status: Active
- Type: CLI video processing utility
- Core tooling: `ffprobe` + `ffmpeg`
- CI checks: C build + C++ syntax check
## Demo Card
[](https://github.com/pulkitpareek18/media-processing-pipeline/blob/main/video.mp4)
CLI utility to generate lower-resolution variants from a single source video using `ffprobe` + `ffmpeg`.
## What It Does
Given one input video file, the pipeline:
1. Detects source resolution with `ffprobe`
2. Creates an output folder named after the source file stem
3. Copies the original source into that folder
4. Produces subordinate resolutions (for example: 1080p -> 720p, 480p, 360p, 240p, 144p)
Output naming format:
```text
/ .mp4
```
## Implementations
- `process_video.c` (cross-platform oriented C implementation)
- `process_video.cpp` (C++ implementation; currently tuned for Windows `_popen`)
## Prerequisites
- `ffmpeg` available on `PATH`
- `ffprobe` available on `PATH`
- C/C++ compiler (depending on implementation)
## Build
### C (macOS/Linux)
```bash
cc process_video.c -o process_video
```
### C (Windows, MinGW)
```bash
gcc process_video.c -o process_video.exe
```
### C++ (Windows, MinGW)
```bash
g++ process_video.cpp -std=c++17 -o process_video_cpp.exe
```
## Usage
```bash
./process_video input.mp4
```
Windows:
```bash
process_video.exe input.mp4
```
## Example
Input:
```text
video.mp4 (1080p)
```
Generated:
```text
video/video 1080.mp4
video/video 720.mp4
video/video 480.mp4
video/video 360.mp4
video/video 240.mp4
video/video 144.mp4
```
## Notes
- The tool currently preserves audio stream via `-c:a copy`.
- Processing time depends on source duration, resolution, and machine performance.
