Enterprise Bridge

Heyyy, hooo, heyyy, hooo...

North beat Lake Park 66-50 tonight, they'll play the winner of tomorrow's Maine South-Conant matchup on Friday, at 7:30, at Conant.

At long last, WGBK-FM is streaming over the Internets. Friday's game (like tonight's game before it) will be on live... at 5:30 PST. Unfortunately, I have a basketball banquet to attend at 6. I want to hear that game, dammit...

I'm in luck. mplayer handles RealMedia streams. And yes, media is neccessary... they stream still graphics images over the audio. mencoder converts the audio to MP3, the video to throwaway low-bitrate MJPEG, and then another trip through mplayer strips the video and leaves the raw MP3 file, and at incredible space savings... a 30-second sample of the Real stream came in at 5 meg. The resulting MP3 file was only 232 K. Admittedly, I stripped it down to mono, but still, what a waste of bandwidth!

Here's the conversion process...

mplayer -noframedrop -dumpfile wgbk-050308b.rm -dumpstream rtsp://

mencoder wgbk-050308b.rm -ovc lavc -oac mp3lame -lavcopts vcodec=mjpeg -ofps 0.1 -lameopts vbr=3:mode=3:q=8:br=64 -o wgbk-050308b.avi

mplayer -dumpaudio -dumpfile wgbk-050308b.mp3 wgbk-050308b.avi
