Hi. This should already be fixed by this commit:
http://git.videolan.org/gitweb.cgi?p=x264.git;a=commit;h=0b0210857ef13214f12861dec672006455a556d6
So update your libx264. As for the question. No, after flushing
delayed frames you can't continue encode another frames in same x264_t
context, you need close it (x264_encoder_close) and open new (x264_encoder_open).
