Players based on ffmpeg like VLC and others could play that file but not others like media player classic and even when I try to convert it to mp4 preserving the original codecs, because I need to analyze it using Elecard StreamEye, ffmpeg fails to do that, here is the command and its output:

ffmpeg -i "c:\output_file.flv" -vcodec copy -acodec copy "c:\output_file.mp4"

I am going to make video on demand files of our live stream which is recorded as one big file for each 24 hours on Flash media server and will need to repeat this chain much: record rtmp video using rtmpdump->mux as mp4 using ffmpeg

Played fine for me too, but with lots of complaints about invalid timestamps.
Very likely the original source is spewing incorrect timestamps.
