The options of the w64 demuxer are a proper subset of the options for
the wav demuxer, making it possible to reuse a part of the options for
the wav demuxer for the w64 demuxer.

The NUT and avi demuxers only need ff_codec_movvideo_tags and so this
removes a dependency on the rest of isom.c as well as on mpeg4audio.c
(which isom depends on); it is similar for the Matroska demuxer and
muxers, except that the mpeg4audio.c dependency can't be avoided.

This is a result of the mov channel parsing stuff being factored out
of mov.c twice: Once in 91b782720fd0df5571775b6591bc41797d6ecf78
to isom.c and later in 3bab7cd12802dc5abf2c5cc6dec49e9e249ce204.
Also remove the isom.h header; and while just at it, remove an unused
mathematics.h inclusion.
Since g2meet.c doesn't use it any more, only encoders use it and
the place for their common code is mjpegenc_common.c.

While just at it, remove the nb_codes parameter: It is redundant
(the number of codes is implicitly contained in the array containing how
many entries of a specific size there are) and for this reason it might
even be wrong, so it is better to check what is actually used instead.

If it isn't, then that might be an issue, but the idea is that with the
logical_processor option you can limit the amount of ram a single encoder
instance will use since on a system

I have on occasion straced node to debug things, and what I have
observed is: I don't want to touch it even with a very long stick.
Wan you explain more precisely why you think libuv would be a

I have a few questions if someone can answer them and help me get started
it'll be nice.
1. Is this a right platform to ask questions, I

For a very long time, the payload of integer and float elements had to
have a length > 0. Our parser treated such invalid elements as having a
value zero. But now it has been defined what an EBML element with length
zero means: It is a shorthand for the default value. This has also been

This is the Matroska equivalent of D_WEBVTT_DESCRIPTIONS and is
therefore only enabled for subtitles.

Hint: Matroska actually provides a way to distinguish the cases of
"track is no commentary track" and "it is unknown whether the track
is a commentary track", but our disposition flags do not. Therefore
we need not use a CountedElement.
