Improving DirectShow seeking. #514

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Currently WebM DirectShow seeking works only keyframe precision. This is bad 
for static content where there is barely new keyframes. 

Play attached file with GraphStudio and see the slider jumping from 27 seconds 
to 35 seconds.

Possible solution: Calculate "necessary" required frame dynamically from the 
keyframe. 

webmsourceoutputpin.cpp
HRESULT Outpin::SetPositions() and maybe mkvparsestreamvideo.cpp, not sure.
