SL3 MediaElement

06-26-2009 8:34 PM |

Decided to do a test to see what has changed in SL3 and MediaElement.  I used a 10 second M4a intended to be looped.  Here are my results:

• Markers created in XAML did not work... ones added after MediaOpened does.
• NaturalDuration incorrect (0:0:10.032 repoted, actual 0:0:10.008).  NaturalDuration information came from file head, though head was wrong about track length.
• If Marker was too close to end, and I tried to stop and play element, the MarkerReached event would fire, but I couldn't play the element
• Second time Element played, beginning cut off.

Hi DDtMM,

As a convenience, would you please share a tiny repro with us?

Best regards,

Jonathan

You can download a small Solution at http://www.DDtMM.com/mp4Test.zip.

• The app creates three Markers in xaml that don't work.  However this seems to be by design?
• The Natural Duration problem is a problem with the mp4 encoding (whose decision was it to use ints?)
• The Marker thing is fickle, and will usually work even with a small time difference.
• The Second play cutoff is pretty obvious to hear.
• I also tried Element Binding.  I didn't expect it to work with natural duration, but I was surprised it didn't work with position.  Maybe I was doing something wrong.

I tried to download your small Solution at the link provided but it's not working.  Can you post it again?

Thanks

Yeah, that's long gone, and I think all the issues are known.  I have some other interesting projects on my site with the MediaElement if you're interested in looping and such
