Implements a BIF server which can produce the BIF files which are needed by a Roku Player to support the video trick modes so that you can see thumbnails of the video when start fast forwarding or rewinding.
Make sure the
ffprobe commands all on your PATH
so that they can be run from the command line.
This starts the BIF server on port 32405
Acessing BIF Images
Lets say you have a video file at
/media/example.mkv, then you can get
a standard definition BIF via HTTP by using the
URL and a high definition BIF by accessing the
The first time you try to access the BIF file you will get an HTTP 503 errors until the BIF is created. The BIF file will get created in a background thread. ffmpeg will be used to extract the BIF file images. Once the BIF file is created requsts for the file will succeed.
Creating the BIF file can take a couple of minutes. It depends on the size of the media
and speed of your machine. You should try trigger the creation of the BIF files eagerly before
you need to use them on your Roku Player. The could be done on the command line using the
curl command. For example:
curl -I http://localhost:32405/media/example.mkv.sd.bif
Eagerly Creating the BIF files using Plex Media Server
You can have the Plex Media Server trigger the eager creation of the BIF file when a media
file is first added the the Plex library. Just add the
BifServer.bundle as Plex plugin.
Then enable it as an agent for your TV shows and Movies.
