Timestamp for each video frame?

Question

Hello,

AVI file format cannot contain some timestamp information for each frame. I have read that the ASF /WMV format supports it. How does it work? Which DirectShow filters do I need, in order to create an ASF video file, which contains timestamps for every frame? Thank you.

best regards,

Vitali

The filter is WM ASF Writer Filter

The WM ASF Writer is a wrapper filter for the writer object provided with the Windows Media™ Format SDK. The filter accepts a variable number of input streams and creates an Advanced Systems Format (ASF) file. The filter handles all compression and multiplexing (although the compression mechanism can be bypassed). You can use the WM ASF Writer in various scenarios including digital video (DV) capture, audio recompression, and conversion of Audio-Video Interleaved (AVI) or MPEG multimedia files for network streaming. This filter provides the only way to create Microsoft® Windows Media™ Audio and Windows Media Video files in Microsoft DirectShow.

For more information, see Creating ASF Files in DirectShow.
