Hi Alon,
StatusInfo looks like this:
[Prefix="Arris::"]
interface StatusInfo {
readonly attribute unsigned long bitrate;
readonly attribute unsigned long networkthroughput;
readonly attribute unsigned long optimalbitrate;
readonly attribute unsigned long droppedframes;
readonly attribute unsigned long stalls;
readonly attribute double decodeFPS;
readonly attribute double renderFPS;
readonly attribute unsigned long audiosegments;
readonly attribute unsigned long videosegments;
readonly attribute unsigned long h264frames;
readonly attribute unsigned long rgbframes;
readonly attribute unsigned long pcmframes;
readonly attribute double seconds;
readonly attribute double duration;
readonly attribute double cacheduration;
readonly attribute PlayerState playerstate;
readonly attribute boolean frontendrunning;
readonly attribute boolean audiodemuxerrunning;
readonly attribute boolean videodemuxerrunning;
readonly attribute boolean decoderrunning;
readonly attribute boolean audiorendererrunning;
readonly attribute boolean videorendererrunning;
readonly attribute PlayerError lasterror;
};
