WMV playback freezes when equalizer is enabled #62

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
When equalizer is enabled and its length is more than 3K WMV playback does
not start.

This happens when video enabled. When video renderer is removed, playback
works fine. But even with null renderer connected directly to the WMV
parser it freezes again.

After start of playback parser sends several chunks and stops. It is
possible to seek, but after the seek it freezes again:

After the seek its possible that parser sends more data, so AC3Filter makes
an output chunk. In this case it may work, but audio buffer constantly
underflows (note the negative latency after Run()):
