# AV1 Opus Encoder (Go Port)
|
|
|
|
This is a Go port of the `av1_opus_encoder.py` script, designed to be compiled into a standalone executable.
|
|
|
|
## Prerequisites
|
|
|
|
- **Go 1.21+**: Required to compile the code.
|
|
- **External Tools**: The following tools must be in your system `PATH`:
|
|
- `ffmpeg`
|
|
- `ffprobe`
|
|
- `mkvmerge`
|
|
- `mkvpropedit`
|
|
- `opusenc`
|
|
- `mediainfo`
|
|
- `av1an`
|
|
- `HandBrakeCLI`
|
|
- `ffmsindex`
|
|
|
|
## Building
|
|
|
|
1. Open a terminal in this directory.
|
|
2. Run `go mod tidy` to ensure dependencies are resolved (standard library only, but good practice).
|
|
3. Build the executable:
|
|
- **Windows**: `go build -o av1-encoder.exe .`
|
|
- **Linux**: `go build -o av1-encoder .`
|
|
|
|
## Usage
|
|
|
|
Place the executable in the directory containing your `.mkv` files and run it.
|
|
|
|
```bash
|
|
./av1-encoder [flags]
|
|
```
|
|
|
|
### Flags
|
|
|
|
- `--no-downmix`: Preserve original audio channel layout (default: false, downmixes >5.1 to stereo/5.1 based on logic).
|
|
- `--autocrop`: Automatically detect and crop black bars (default: false).
|
|
- `--speed`: Set SVT-AV1 preset (e.g., `slower`, `slow`, `medium`, `fast`).
|
|
- `--quality`: Set SVT-AV1 quality (e.g., `medium`, `high`).
|
|
- `--grain`: Set film-grain synthesis level (int).
|
|
|
|
## Moving to a New Git Repo
|
|
|
|
This directory is self-contained. You can move the entire `av1-go` folder to a new location and initialize a new git repository:
|
|
|
|
```bash
|
|
mv av1-go /path/to/new/location
|
|
cd /path/to/new/location
|
|
git init
|
|
git add .
|
|
git commit -m "Initial commit"
|
|
```
