Multiple locations for VOD in 0.9.8

Last week I've added support for multiple play locations in VOD engine. Until 0.9.8 play directive could only receive a single directory or http location to play from. Now it receives multiple locations. Playback is started from the first location where file is found.

application vod {
    # search in /var/videos; in case of failure search in /www
    play /var/videos /www;
}

application vod {
    # search in local directories; if not found go to remote server
    play /tmp/cache /var/videos http://example.com/videos;
}

Another new feature in 0.9.8 is play_local_path setting. This directive sets directory where remote files are copied after they are completely downloaded from http location. The setting is unset by default. This directory should be on the same device as play_temp_path setting which sets temporary location where remote files are downloaded. Default is /tmp.

With the new features it's easy to set up local cache for remote files.

application cached_vod {
    # remote files are copied to /tmp/videos after download
    # and played later from local directory until deleted manually

    play_local_path /tmp/videos;
    play /tmp/videos http://video.example.com/videos;
}
