Set Positions returns E_NOTIMPL

Question

Hi,

I want to write only a specific portion of a .avi file in the output .avi file .For this I follow Source Filter ->Avi mux->File Writer.I try to use IMediaSeeking on the Mux to set the specific start and stop times using Set Positions but it returns E_NOTIMPL. I also try to query the graph builder for IMediaSeeking and try to set the start and stop positions with no success.Can someone help?

Answer 1

Query for IMediaSeeking on each of the output pins connected to the mux inputs, and set the positions on those.
