# TapeXPlayer
**TapeXPlayer** is a video player developed as a simulation of media playback on magnetic tapes, based on the philosophy of professional Betacam video recorders. The program is designed for scientific purposes, particularly for frame-by-frame film analysis.
### Key Features
TapeXPlayer is written in C++ using the **FFmpeg**, **SDL**, **GStreamer**, and **OpenSSH 3.0** libraries. The primary goal of the program is to adapt the functionality of professional video tape players for use on modern computers. TapeXPlayer helps to thoroughly examine the video sequence, simplifying frame-by-frame analysis and playback control.
- Smooth playback forward and backward with shuttle control up to 18x speed, with minimal CPU and memory usage.
- Fast seek by timecode.
- Supports multiple video formats thanks to the **FFmpeg** library.
- Minimal system resource consumption at high playback speeds (expected: ~132% CPU @ 16x shuttle, and ~27-41% CPU – playback @ 1x).

### Running the Program
Run the program via the command line using the following format:
```
./TapeXPlayer
```
or
```
./TapeXPlayer
```
### Important Notes
- TapeXPlayer creates low-res cached versions of the video to ensure smooth playback and seeking. The cache is saved at the following path: `/Users//Library/Caches/TapeXPlayer`. Make sure there is enough free space on the disk to store the cache. The number of cached files is limited to 3.
### Controls:
- **Spacebar** — Play/Pause.
- **G** — Switch to frame seek mode based on timecode. Enter time in the following format: HHMMSSFF (hours, minutes, seconds, frames).
- **Up/Down Arrows** — Control playback speed (from normal to 16x).
- **Left Arrow** — Change playback direction (forward/backward).
- **Shift + Left/Right Arrows** — Slow-motion playback (jog mode).
### System Requirements
- Mac with Apple Silicon (or Intel)
- macOS 11.0 (Big Sur) or newer
### Libraries and Dependencies:
- **GStreamer** — for multimedia framework support.
- **PortAudio** — for audio processing module.
- **FFmpeg** — for decoding and encoding video and audio.
- **SDL** — for cross-platform multimedia capabilities and display.
- **OpenSSH 3.0** — for file generation with unique identifiers, optimizing workload.
