Unknown encoder 'libfaac'

C:\Program Files\get_iplayer\ffmpeg\bin>

This version of FFmpeg has been compiled without "libfaac" enabled.

So (for now) use FFmpeg's own "aac" codec instead of "libfaac".
Using your Windows get_iplayer version of FFmpeg....
Try again with this command:-
ffmpeg -i filename.mkv -t 60 -vf "scale=1280:trunc(ow/a/2)*2" -vcodec libx264 
-acodec aac -ab 128k -ac 2 -strict experimental filename.mp4
                                        
Hi,

that works only with latest ffmpeg-git-fd0b8d5-win32-static :) Thank you very much.
Few questions, looking at the recording from the device (Nokia N8):

is there any way to make Video:
1280x720,
Format settings CABAC = No,
add the subtitles and then rest of the settings so that the final muxed file is up to or not bigger than 4GB?

Here is the muxed testfile:
