Video Converter User Guide
Convert common video files into resources playable by BigSmart firmware.
RYMCU BigSmart Video Converter converts common video files into resources that can be played by the BigSmart firmware. After conversion, the tool generates .mjpg, .mp3, and .fps files with the same base name. Copy all three files to the /videos directory on the SD card to play them on the device.
Tool Location
tools/video-converter/RYMCU-Video-Converter.exe
FFmpeg is bundled with the tool, so the target computer does not need a separate FFmpeg installation.
Supported Formats
Common video formats are supported, including:
mp4movavimkvflvwebmm4vwmv3gp
Conversion Steps
- Double-click
tools/video-converter/RYMCU-Video-Converter.exe. - Click "Select Video", or drag a video file into the window.
- Keep the default parameters, or adjust them as needed.
- Click "Start Conversion".
- After conversion, check that the output directory contains three files:
video-name.mjpg
video-name.mp3
video-name.fps
Recommended Settings
| Setting | Recommended value | Notes |
|---|---|---|
| Video frame rate | 8-12 fps | Recommended for a balance between smooth playback and decoding load |
| Fast-motion video | 12-15 fps | Smoother playback, but larger files and higher decoding load |
| JPEG quality | 8 | Default recommended value |
| MP3 sample rate | 44100 Hz | Default recommended value |
| Smaller audio files | 16000 Hz | Optional when reducing audio size is more important |
The matching firmware reads the .fps file with the same base name to keep audio and video synchronized.
Copy Files to the SD Card
Copy the three generated files to the /videos directory on the SD card:
/sdcard/videos/video-name.mjpg
/sdcard/videos/video-name.mp3
/sdcard/videos/video-name.fps
If the SD card does not contain a videos directory, create it manually first.
Notes
- The three output files must keep the same base name. Only the file extensions should differ.
- Use English letters, numbers, hyphens, or underscores in video file names for better path compatibility across systems.
- Higher frame rates and higher image quality produce larger files and increase the decoding load on the device.
- If playback is not smooth, lower the frame rate or JPEG quality first.
