is there a way to change the default output file from avi to mp4 in directshow?

it is already generating avi file format, i开发者_开发技巧 want to change the output format

You just need to install MP4 muxer and use it instead of AVI Mux. Google for "MP4 Muxer" to find them. For start: http://www.3ivx.com/technology/filters/media_muxer.html http://www.gdcl.co.uk/mpeg4/
