+# sshcam
+
+Webcam live streaming in SSH terminal.
+
+[DEMO](https://asciinema.org/a/14968)
+
+## Install
+
+**Install binary from GitHub** if you don't have a Go development environment:
+
+```bash
+curl -sL https://github.com/kfei/sshcam/releases/download/v1.0.0/sshcam-v1.0.0-x64.tar.bz | tar xj
+```
+
+**Build from source** (also requires GCC):
+
+```bash
+go get -u github.com/kfei/sshcam
+cd $GOPATH/src/github.com/kfei/sshcam
+go build
+go install
+```
+
+## Quick Start
+
+Preview the live stream locally via `sshcam` (without any argument). Also note
+that you should run `sshcam` as an user with privilege to open `/dev/videoX`.
+
+Start the SSH server with all default settings:
+
+```bash
+sshcam --server
+```
+
+Then on the client-side, run:
+
+```bash
+ssh [email protected] -p 5566 # Default login: sshcam/p@ssw0rd
+```
+
+Note that there are more configurable settings for server, have a look at
+`sshcam -h` for more details. For example,
+
+```bash
+sshcam --server --listen=127.0.0.1 --port=22222 \
+       --user=john --pass=nhoj \
+       --device=/dev/video0 --size=1280x720
+```
+
+## Requirements
+
+  - On the client-side, a standard `ssh` utility is enough.
+  - Video device is supported by 
+    [V4L2](https://www.kernel.org/doc/Documentation/video4linux/v4l2-framework.txt),
+    which means the server is currently Linux only.
+
+## TODO
+
+There are still lots of interesting works to be done. Discussions and pull
+requests are both welcome. :)
+
+  - *P2P functions*: So that it can be a terminal video messenger.
+  - *Higher resolution*: Can this be done by using the Unicode block
+    characters?
+  - *Colors*: In a *xterm-256color* terminal, display images with colors.
+  - *Port to other platforms*, maybe QT?
+  - *Improve algorithm*: Currently the image scaling is inefficient and lossy.
