[FFmpeg-user] using Directshow filter to modify mpeg-4 video

[Alexey Kool]

Hello all!
I have writen my own DirectShow filter. I am using it with popular video
players and have no problems. So I need to apply my filter to some mpeg-4
video file. As i think i need to use ffmpeg to recode video file applying
my filter.
So the question is can I solve my problem using ffmpeg (for windows)?

For example the procedure is:
input_file(mpeg4) -> ffmpeg (using my filter) -> output_file(mpeg4)

Regards!
