+ * in which case the #GstX264Enc:quantizer property controls much of the outcome, in that case #GstX264Enc:bitrate is the maximum bitrate.

* The H264 profile that is eventually used depends on a few settings.
* If #GstX264Enc:dct8x8 is enabled, then High profile is used.
* Otherwise, if #GstX264Enc:cabac entropy coding is enabled or #GstX264Enc:bframes

+ * applies. The main profile is imposed by default,
+ * which is fine for most software players and settings,
+ * but in some cases (e.g. hardware platforms) a more restricted profile/level
+ * may be necessary. The recommended way to set a profile is to set it in the
+ * downstream caps.
+ *
+ * If a preset/tuning are specified then these will define the default values and
+ * the property defaults will be ignored. After this the option-string property is
+ * applied, followed by the user-set properties, fast first pass restrictions and
+ * finally the profile restrictions.
+ *
+ * <note>Some settings, including the default settings, may lead to quite
+ * some latency (i.e. frame buffering) in the encoder. This may cause problems
+ * with pipeline stalling in non-trivial pipelines, because the encoder latency
+ * is often considerably higher than the default size of a simple queue
+ * element. Such problems are caused by one of the queues in the other
+ * non-x264enc streams/branches filling up and blocking upstream. They can
+ * be fixed by relaxing the default time/size/buffer limits on the queue
+ * elements in the non-x264 branches, or using a (single) multiqueue element
+ * for all branches. Also see the last example below.
