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.<br>
<br>
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.<br>

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.<br>

Yes I am. For more information, I am developing on

avcodec_open2 can fail if you lack the library for the
codec you want to decode or encode. For example,
libx264. The libraries in <a moz-do-not-send="true"
href="http://ffmpeg.zeranoe.com" rel="noreferrer"
target="_blank">ffmpeg.zeranoe.com</a> 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.<span

he is using pre-built packages from zeranoe site (as you

<div class="gmail_extra">@Kevin: maybe you have some bare
minimum code with you that can produce this error, which
people can have a look? <br>
