An MP4 file normally contains H.264 video and AAC audio, both of which are compatible with the FLV container. You could simply copy over the streams: ffmpeg -i input.mp4 -c copy output.flv Since you're copying the streams, this will be as close to instantaneous as you're going to get and will not result in any loss of quality.
