     1  # play-from-disk-renegotiation
     2  play-from-disk-renegotiation demonstrates Pion WebRTC's renegotiation abilities.
     3  
     4  For a simpler example of playing a file from disk we also have [examples/play-from-disk](/examples/play-from-disk)

     6  ## Instructions
     7  
     8  ### Download play-from-disk-renegotiation
     9  This example requires you to clone the repo since it is serving static HTML.
    10  
    11  ```
    12  mkdir -p $GOPATH/src/github.com/pion
    13  cd $GOPATH/src/github.com/pion
    14  git clone https://github.com/pion/webrtc.git
    15  cd webrtc/examples/play-from-disk-renegotiation
    16  ```
    17  
    18  ### Create IVF named `output.ivf` that contains a VP8 track
    19  
    20  ```
    21  ffmpeg -i $INPUT_FILE -g 30 -b:v 2M output.ivf
    22  ```
    23  
    24  **Note**: In the `ffmpeg` command, the argument `-b:v 2M` specifies the video bitrate to be 2 megabits per second. We provide this default value to produce decent video quality, but if you experience problems with this configuration (such as dropped frames etc.), you can decrease this. See the [ffmpeg documentation](https://ffmpeg.org/ffmpeg.html#Options) for more information on the format of the value.
    25  
    26  ### Run play-from-disk-renegotiation
    27  
    28  The `output.ivf` you created should be in the same directory as `play-from-disk-renegotiation`. Execute `go run *.go`
    29  
    30  ### Open the Web UI
    31  Open [http://localhost:8080](http://localhost:8080) and you should have a `Add Track` and `Remove Track` button.  Press these to add as many tracks as you want, or to remove as many as you wish.
