<div>Hi William,<br>
<br>
I'm by no means an expert on the matter but I tried having a look for you.<br>
At least one issue would be that you are not calling<br>
avformat_network_init() which<br>
is a requirement for any protocol which needs network [1]<br>
<br>
I would have tested and tried this for you, however I do not have the<br>
hardware laying around.<br>
<br>
I wish you the best of luck and let me know how it goes.<br>
<br>
[1] - libavformat/libavformat.h lines 40-41<br>
