streamera

streamera is a Stream Camera based on TCP, which contains client mode and server mode.

Features

• Client Mode & Server Mode

  • Client Mode

    Capture camera video and send stream to server side.

  • Server Mode

    Receive tcp stream and display the video to screen, along with network speed and ping.

• Connection-Error Handle

  • Client Mode

    streamera client will try to reconnect to the server every 3 second when TCP connection is lost. And the maximum buffered size is 180 frames, which is probably up to 6 seconds of the video.

  • Server Mode

    streamera server will continuously serve the incoming tcp connection, but the limit is set up to 1 client at the same time, which means only one video window will be shown during streamera server running.

    To be simple, When current TCP connection is lost, the server will wait for the next incoming connection and start over the video streaming.

• Encoded Stream

  Use jpeg library to encode each frame instead of the raw RGB stream

• Speed & Ping Monitoring

  Draw current network speed and ping directly to the video frame.

• Thread Safe

  streamera uses golang as the main programming language: goroutine, channel and mutex are widely used in streamera. Thus, streamera has high performance and stability while keeping thread safe.
