Lacing not supported, resulting in empty audio track #220

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
If you open a webm file that uses lacing (multiple audio frames per block), 
then the resulting movie with have an empty audio track and silence when played 
in QT player.  

The dependent library libwebm was recently changed to support lacing.  Its 
interface has changed also: the Block::GetOffset() call has been removed.  

The log shows:
AddMediaSampleRefereces() FAILED with err = -2014

Need to calculate a duration for each frame of the block, because QT bails if 
duration is 0.
