x264 can do that so it is mostly add an

that would be

send another onMetaData with the new extradata.
It shouldn't take much if you force it to be single threaded.
Sounds like a bit more effort than it's worth to be honest guys.
It should be more or less an a branch and a function call at least the
single threaded situation.
I can
just restart the stream at a different resolution I guess - bit more
overhead but it's "safer".
The main difference is that you have some more latency piling up, but in
concept isn't different.

Just to clarify:
In order to "reconfigure_x264" would I just need to
"avcodec_set_dimensions" mid stream?
In order to "send another onMetaData with the new extradata" would that
be just another call to "av_write_header"?
How do I ensure that LibAV runs in single threaded mode?
Thanks,
Mark.
