DirectShow Sample -- DSSeekFm
-----------------------------
Demonstrates how to:
- Use DirectShow's Windows Media SDK-based ASF Reader Filter to play
ASF content in a DirectShow graph
- Use the Corona SDK's frame-seeking support (which isn't yet supported
by the DirectShow ASF Reader filter) to get the associated frame time to
use when seeking the DirectShow graph. Note that ASF frame-based seeking
is only supported with frame-indexed ASF files.
Specify the name of a frame-seekable ASF source file.
With no other options specified, the file is played to completion.
Otherwise, the file is seeked and played back for the specified duration.
Usage:
DSSeekFm [/f FrameStart NumFramesToPlay] [/l LoopModeIncrement] Filename
The following command-line switches are supported:
/f Specifies the starting frame (1-based) and number of frames to play
/l Loops until EOF, playing number of frames specified by /f switch,
and incrementing start frame by LoopModeIncrement
Example: DSSeekFm /f 100 50 frameseek.wmv
This will seek to frame 100 and play 50 frames.
Example: DSSeekFm /f 100 10 /l 50 frameseek.wmv
This will seek to frame 100, play 10 frames, advance 50 frames,
play 10 more frames, advance 50 frames, etc. until completion.
