SBS has increased its bitrate and number of streaming options (at different bitrates / quality), from 3 to sometimes 4.
eg, 'Trafficked' is available in (nominal bitrate) 128K, 300K, 1000K
(see hxxp://player.sbs.com.au/video/smil/index/standalone/346597)
and 'The Bombing Of Germany Full Ep' is available in 128K, 512K, 1000K, 1500K.
(see hxxp://player.sbs.com.au/video/smil/index/standalone/515791)
I discovered this while poking around, when SBSNapper was not connecting well over the last 3 days. I reverted to batch downloading (using a very ad hoc method), and this involved looking at various XML files with a browser.
Also, I noticed that some shows were very large for the time duration - due to a bigger bitrate for the video. The audio bitrate doesn't contribute much file size.
MediaInfo (hhtp://mediainfo.sourceforge.net/) is useful to see bitrate for both the video and the audio, once a show is downloaded.
afaik, unfortunately,
RTMPdump displays the duration, audio and video bitrates etc - but cannot feed the info back to the calling program (eg, SBSNapper or other downloaders).
SBSNapper has 3 buttons for different bitrates, which is quite useful.
I have been experimenting with some code that reads the show's XML file (eg, 515791 for 'The Bombing Of Germany '), and displays the correct number of buttons with the nominal bitrate displayed as the button text. Not a very useful function, but it amused me for an hour or so.
The last few days has made me contemplate whether SBS may change their streaming system quite drastically, sometime soon. That will be more fun!
