In 0.6.0.3980, frames being encoded can be viewed. The frame is rendered with SDL at a specified interval so it won’t slow down the encoding speed noticeably and can be switched on/off instantly.
Please note that in some combinations (when video source is “default”, in this case, frames are not passing through MediaCoder), this feature won’t work.
In this build, several serious bugs have been fixed. For details please check the changelog.
