I am setting the AudioCodec to MP3, I am using the pre-built libraries
the code I have the causes the issue is from the code for the QtMEL
library. What I am posting here is the Audio Codec setup for the QtMel
object. I hope it helps.
BTW I am using H264 for the Video Codec. If I record video only, it
does work, it is only if I try to add sound that it fails.
CR2CAudioFormat format;
format.setChannelCount(2);
format.setSampleRate(44100);
format.setFormat(CR2CAudioFormat::SignedInt16);
I really don't have a preference for the codec, I just need to know how
to set it up properly. I am totally new at recording video and audio.

avcodec_open2 can fail if you lack the library for the codec you
want to decode or encode. For example, libx264. The libraries in
ffmpeg.zeranoe.com <http://ffmpeg.zeranoe.com> contain all codecs,
but they are GPL only. You should try them first and see if the
problem goes away. If it does, you know you have to compile
ffmpeg with different flags.
Since he mentions Windows 7, I assume he is using pre-built packages
from zeranoe site (as you mention). These builds contain proprietary
codec(s) like x264 (non GPL).
@Kevin: maybe you have some bare minimum code with you that can
produce this error, which people can have a look?
