Hello list members,
I'm trying to playback a mp4 video which contains 5.1ch audio with ffplay. The
mp4 file was made from DVD stream dump with mplayer, like the following ffmpeg

-map 0:0 -c:v libx264 -preset slow -level 4.1 -profile:v

Hi there,
I recorded an screencast in WinXP using the following command:
ffmpeg -f gdigrab -framerate 5 -i desktop -f dshow -i audio=Realtek HD
Audio Input -vcodec libx264 -crf 0 -acodec pcm_s16le output.flv

brew install ffmpeg // seems to work
cd folder with wmas
for f in *.wma; do ffmpeg -y -i $f -c:a libfdk_aac -b:a 192k
${f%.wma}.m4a; done;
// try a script
- error Unknown encoder 'libfdk_aac'
any ideas?

Hi all,

Thanks of course I copied that off a discussion of bringing wma into iTunes.
