# fstream
A TCP multi-broadcast media streaming server/client. [Check out the past source](/Fierelier/fstream/src/commit/1890b316f543f579e9a63f3a2ddb689eeef9c855), for simpler implementation.

# Client
You can send and receive any data using the right software. Here are some examples with ffmpeg:
- `fstream.py 127.0.0.1:61920 watch,user=fier,channel=exampleChannel,channel-password=123 | ffplay -i -` - Watch `fier`'s `exampleChannel` channel at `127.0.0.1:61920`, supplying `123` as a password, and pipe it into ffplay for playback.
- `ffmpeg -f gdigrab -framerate 30 -i desktop -vf scale=-2:480 -c:v libx264 -pix_fmt yuv420p -maxrate 1M -f h264 - | fstream.py 127.0.0.1:61920 broadcast,user=fier,user-password=123,delay=0.1,channel=exampleChannel,channel-password=456` - Broadcast Windows desktop as `fier` to `127.0.0.1:61920`, supplying `123` as the user password with a server loop-delay of `0.1` seconds. `exampleChannel` is the channel, `456` is the channel's password. Pipe the output from ffmpeg.

# Server
## Settings
Edit `modules/settings.py` for generic server/socket-related settings, and `modules/fstream/settings.py` for fstream related settings.

## Creating a user
Make a folder called `users` and make a file in it called `YourUsername.ini`, put this in it:
```ini
[DEFAULT]
password=foobar
```
If you would like to implement your own authentication, make your own module to replace the `authenticate()` function - see `modules/fstream/authent.py` and `modules/fstream/main.mods`.

# The Protocol
## Establishing a connection
Establish a TCP connection with the server, and send the payload. If the server likes your payload, it will stream data to you, or accept more of your data.

## The payload
Send the length of the payload as a 4-byte (32-bit) big endian unsigned integer, a null byte (hex:`00`) and a UTF-8 encoded string identifying the client's intentions. For example: `watch,user=fier,channel=exampleChannel,channel-password=123` or `broadcast,user=fier,user-password=123,delay=0.1,channel=exampleChannel,channel-password=456`. If you are a watcher, you will be blasted with data. If you are a broadcaster, you can now blast data.
