[Libav-user] File does not seem to close

[Kevin J. Brooks]

I am using "av_interleaved_write_frame" to write the video frames. The 
plan is to add audio capture from a microphone as well.

I noticed avio_close_dyn_buf is wanting a pointer to a buffer. Since I 
don't explicitly create a buffer, I don't know where I should get it.
