Hello,
I am a directshow developer, but I haven't many experiences. Now, I encounter a problem. How to convert a period of MPEG-1 file into a new MPEG file(MPEG-1,MPEG-4 or DIVX)?
My project is based on motion detection. It will analysis a MPEG-1 video,recording the starttime and stoptime when motion happens.
For example,I know a movement from the 36 second to the 114 second and from the 180 second to the 210 second. Then I use directshow DES funtion to create a XTL file dynamically which could bring the two periods of video together.
The final step is changing it into a new file. But directshow can store it in AVI or ASF format and doesn't contain a MPEG encoder.What should I do?my program will run automatically, so I can't use other software such as Adobe Premiere to finish it.
If we could get such a encoder,how to connect it into directshow DES?
By the way, my project is just a supervisory equipment research. It's best for me to use free encoding filter.
I hope you could help me resolve the problem. If you have any good solution,please send me a e-mail.
Thanks a lot.
