Hi Elie,
This has worked for me in the past. c:\ffmpeg.exe -loglevel error -i
inputfile.wmv -vf "transpose=0" -vf "hflip" "converted.mp4" My apologies
in advance if this is a n00b answer to your question.

Thanks!

Could you test the following command lines?
$ ffmpeg -f lavfi -i testsrc -pix_fmt yuv420p -t 10 out1.mp4
$ ffmpeg -f lavfi -i tests

WMP doesn't respect the metadata rotate flag, I tried that.
Please see below the command line output.
The transposed video can be played back with VLC.
With WPM I can hear the sound, but no video.
I also tried the foll

Not really: I forgot to mention that nothing except x264 and FFmpeg
