<div>Dear All,<br> <br>I've historically used a GPL compiled version of FFmpeg to convert to the 3GP format and it worked perfectly with the following command line:<br> <br>ffmpeg.exe -i sample1.flv -vcodec mpeg4 -acodec aac -strict experimental -ac 1 123.3gp<br>
<br>However, in the last few weeks I've moved to a LGPL compilation for licensing reasons. The LGPL builds were produced by Zeraneo based on ffmpeg-20120511-git-9eb99ab-win32-shared-lgpl.<br> <br>However, now I cannot get the above command line to work and cannot convert to the 3GP format.<br>
<br>I am passing '-strict experimental' and the FFmpeg DLL returns a code which suggests it has successfully accepted the parameter (it’s in opt_default function). But later, in the code it fails with the same error – 'code is experimental'.<br>
<br>I've also tried using the following command line but this also fails:<br> <br>ffmpeg.exe -i sample1.flv -vcodec mpeg4 -acodec libvo-aacenc -ac 1 123.3gp<br> <br>Can anyone help? Thanks.</div>
