<p>Have you read through the License Compliance Checklist? Read it
carefully. There is a very significant difference between GPL and
LGPL for non GPL source code applications. See point #1.<br>

#3 - Distribute the source code of FFmpeg, no matter if you modified

You do <u>not</u> need to distribute the object files if linking

<div style="color:rgb(37,37,37)">Q2) This could be a silly
question. One of the open-source projects I used needed to be
paid to use their codes. (This was a really rare case for me a
long time ago.) Because of this, I was wondering if we have to
pay to use libav.</div>
