Good afternoon. I'm a pretty big noob to video transcoding so I figured I would ask the experts. I've got a small collection of MKVs encodes that I would like to convert to FLVs for embedding in a webpage for my personal use. I am having some trouble doing this using ffmpeg however. Below is the log of the encode:

Seems stream 0 codec frame rate differs from container frame rate: 47.95 (27956/583) -> 23.98 (24000/1001)
Input #0, matroska, from 'test.mkv':

Stream #0.1(eng): Audio: libmp3lame, 48000 Hz, 6 channels, s16, 64 kb/s
Stream mapping:
Stream #0.0 -> #0.0
Stream #0.1 -> #0.1
Error while opening encoder for output stream #0.1 - maybe incorrect parameters such as bit_rate, rate, width or height
I have tried google searching but the closest information I can find is to "invert the mapping" which is a simple checkbox in the GUI but I am running ffmpeg from command line and I haven't found much documentation on the -map command. My basic goal is to simply convert the contents of the mkv to flash without any adjustments and probably mix the audio down to stereo, couldn't care less about the subtitles. I would like to use ffmpeg and need to keep this on my linux server if possible but if another linux command line tool will do the job I am open to suggestions.
