I know the interface between libavcodec and libx264 is such that you can pass at least some of the native x264 option strings, such as preset names, through the opts argument to avcodec_open2(). However it also appears that this is not enough to put the codec into a usable state. <br>
<br>Is it spelled out anywhere just what has to be set in the libavcodec contexts, and what can be set up with x264 options?<br><br>Thanks<br><br>
