The element was only being written when the value == 1. But the default
value of this element is 1, so this has no useful effect. This element
needs to be written when the value == 0.

On failures in the write_trailer function, we could also ignore
the errors and try to finish the file despite these errors (which
would only leave an incomplete chapters track). It's probably better
to signal the error clearly to the caller though (and if this
function failed there's no guarantee that there's enough memory to
finish the trailer either).

When a id3 tag is larger than the amount of space we will probe
give it a score similar to what a .mp3 extension would have given it

This allows creation of frame accurate chapter marks from sources
like DVD and BD where the precise chapter location is not known until
the chapter mark has been reached during reading.

Allow emitting the current cluster that is being written before
starting a new one, simplifying how to figure out where clusters
are positioned in the output stream (for live streaming).

WebM files now support inband text tracks, as described in the
following specification:
http://wiki.webmproject.org/webm-metadata/temporal-metadata/webvtt-in-webm
The Matroska demuxer now detects the presence of WebVTT tracks,
synthesizing WebVTT packets (having codec id AV_CODEC_ID_WEBVTT) and
pushing them downstream in the normal way.

Seeking in certain broken files would cause ogg_read_timestamp
to fail because ogg_packet would go into a state where all packets
of stream 1 would be discarded until the end of the stream.

This avoids the loss of a packet in many cases if the packet size was wrong.
It also improves detection of packet size changes

No case is known to have triggered this, but its more correct to check that the
new size differs.
