Comment (by agowad):
Hello
I have used instructions from following article to build ffmpeg under
windows:
[http://www.gooli.org/blog/building-ffmpeg-for-windows-with-msys-and-
mingw/]
However, after running make I received a few errors. Therefore, I have
great request to you - Could you please try to test it on your development
machine or point me to some tutorial that may work?
Unfortunately, the media file I used initially (Dolphins_720.wmv) is 72MB,
therefore, I have chosen different, smaller one
(fishermans_friendCD_720_xvid.avi). I will add it as attachment to this
ticket. Below I put outputs of previously requested commands.
* COMMAND
{{{
ffmpeg.exe -i "fishermans_friendCD_720_xvid.avi" -ar 44100
"fishermans_friendCD_720_xvid_TMP.flv"
}}}
* OUTPUT
