     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  git clone https://github.com/pion/webrtc.git
    13  cd webrtc/examples/play-from-disk-renegotiation
    14  ```
    15  
    16  ### Create IVF named `output.ivf` that contains a VP8 track
    17  
    18  ```
    19  ffmpeg -i $INPUT_FILE -g 30 -b:v 2M output.ivf
    20  ```
    21  
    22  **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.
    23  
    24  ### Run play-from-disk-renegotiation
    25  
    26  The `output.ivf` you created should be in the same directory as `play-from-disk-renegotiation`. Execute `go run *.go`
    27  
    28  ### Open the Web UI
    29  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.
