+ * @copy_frame_flags: copy the KEY/B/PFRAME flags as well.

+ * This helper function copies the timestamp, timecode (if the TIMECODE
+ * buffer flag was set), field and the TIMECODE, KEYFRAME, BFRAME, PFRAME
+ * and TSTAMP_SRC_MASK flags from @out_vb to @cap_vb.
+ *
+ * If @copy_frame_flags is false, then the KEYFRAME, BFRAME and PFRAME
+ * flags are not copied. This is typically needed for encoders that
+ * set this bits explicitly.
