# atranscoder-rpc

Audio transcoder with simple HTTP API. Work in progress.

# What works

Transcoding:
1. `cargo run`
2. Upload file for transcoding:
```bash
curl --location 'http://localhost:8090/enqueue' \
    --form 'file=@"/home/user/Music/test.mp3"' \
    --form 'format="adts"' \
    --form 'codec="aac"' \
    --form 'bitRate="64000"' \
    --form 'maxBitRate="64000"' \
    --form 'sampleRate="8000"' \
    --form 'channelLayout="mono"' \
    --form 'uploadUrl="http://127.0.0.1:8909/upload"'
```
3. You will receive JSON response with job ID. The transcoding result will be saved into `/tmp/{job_id}.out.atranscoder`

# Roadmap
- [ ] Implement acceptable error handling.
- [ ] Restart threads in case of panic.
- [ ] Remove old conversion results and input files every Nth hours.
- [x] Remove input file after transcoding it.
- [x] Implement file upload to `uploadUrl` (if `Content-Type: application/json` then conversion was not successful and body contains an error info).
- [x] Remove transcoding result after uploading it to the `uploadUrl`.
- [ ] (Optional) Make `uploadUrl` optional and allow the client to download the file on-demand.
- [ ] Docker image for `amd64` and `aarch64`.
- [ ] Statically linked binary for Docker image & result docker image based on `scratch` (reduce image size).
- [ ] Tests!
