[FFmpeg-user] MKV To MP4

Hi there,

I am not sure whether this is a windows media player issue or FFMPEG. I am
using ffmpeg to capture the screen and record audio, whilst playing games.
It does a great job and I save the file as an mkv. I can convert the file
to mp4 and all seems fine. However when I try to play the file  with
windows media player version 12.019 etc. I get "network is too busy to play
file at original quality" and it just sits there doing nothing. If i open
windows media player classic, it plays the mp4 file perfectly with no
problems at all. This is the ffmpeg command I used to convert the mkv file
to mp4

ffmpeg -i laptop.mkv -c copy laptop.mp4

Is it possible that it may be the command I used to create the MKV file
shown below.

"/k ffmpeg.exe -y -probesize 10M -rtbufsize 1500M -f dshow -i audio=""" &
Audio_name & """ -acodec pcm_s16le -f gdigrab -framerate 60 -i desktop
-vcodec libx264 -qp 0 -threads 0 -crf 18 -preset ultrafast -tune
zerolatency " myFile.mkv"

Or is it windows media player 12.0 ??

Any help with this will be really appreciated. Thanks

All the best,
