[FFmpeg-user] backtrack parameters from existing file

Is there anyway that ffmpeg can look at an existing video file and provide
the switches used to create that fiile - or at worst case, provide
switches to create similar output?

We are trying to use ffmpeg to transcode to mp4 and need to match
quality/bitrate/etc of an existing file as close as possible.

Thanks in advance
