Just curious: Why can't you use the FFmpeg executable? Or to say it differently: Is there an input sample file that is not supported by FFmpeg? > This is working well with one exception, I can't tell what the frame rate is > ahead of time because I can't read the files before I process them. FFmpeg's mov muxer only supports cfr, so you have to know the framerate in advance.
