It allow other Home-Assistant components to process video/audio streams. It need a ffmpeg binary in your system path. It support all ffmpeg version since 3.0.0. If you have a older version, please update.

You need a `ffmpeg` binary in your system path. On Debain 8 or Raspbian (Jessie) you can install it from backports. If you want Hardware support on a Raspberry Pi you need to build from source by yourself. Windows binary are avilable on the [FFmpeg](http://www.ffmpeg.org/) website.

To set it up, add the following information to your configuration.yaml file:

ffmpeg:

Configuration variables:

• ffmpeg_bin (Optional): Set the ffmpeg binary (eg. /usr/bin/ffmpeg). Default 'ffmpeg'.
• run_test (Optional): Check if input is usable by ffmpeg. Default True.

In most of case, ffmpeg autodetect all needed options to read a video/audio stream or file. But it is possible in rare cases that's needed to set a option to help ffmpeg. Per default ffmpeg use 5 seconds to detect all options or abort.

First check, if your stream playable by ffmpeg with (use option -an or -vn to disable video or audio stream):

$ ffmpeg -i INPUT -an -f null -

Now you can see what going wrong. Following list could be help to solve your trouble:

• [rtsp @ ...] UDP timeout, retrying with TCP: You need to set RTSP transport in the configuration with: input: -rtsp_transport tcp -i INPUT
• [rtsp @ ...] Could not find codec parameters for stream 0 (Video: ..., none): unspecified size: FFmpeg need more data or time for autodetect. You can set the analyzeduration and/or probesize option, play with this value. If you know the needed value you can set it with: input: -analyzeduration xy -probesize xy -i INPUT. More information about that can be found on FFmpeg.
