wm4 ac1c5e6e18 demux_mkv: improve robustness against broken files
Fixes test7.mkv from the Matroska test file collection, as well as some
real broken files I've found in the wild. (Unfortunately, true recovery
requires resetting the decoders and playback state with a manual seek,
but it's still better than just exiting.)

If there are broken EBML elements, try harder to skip them correctly.
Do this by searching for the next cluster element. The cluster element
intentionally has a long ID, so it's a suitable element for
resynchronizing (mkvmerge does something similar).

We know that data is corrupt if the ID or length fields of an element
are malformed. Additionally, if skipping an unknown element goes past
the end of the file, we assume it's corrupt and undo the seek. Do this
because it often happens that corrupt data is interpreted as correct
EBML elements. Since these elements will have a ridiculous values in
their length fields due to the large value range that is possible
(0-2^56-2), they will go past the end of the file. So instead of
skipping them (which would result in playback termination), try to
find the next cluster instead. (We still skip unknown elements that
are within the file, as this is needed for correct operation. Also, we
first execute the seek, because we don't really know where the file
ends. Doing it this way is better for unseekable streams too, because
it will still work in the non-error case.)

This is done as special case in the packet reading function only. On
the other hand, that's the only part of the file that's read after
initialization is done.

mpv
###

Overview
========

**mpv** is a movie player based on MPlayer and mplayer2. It supports a wide
variety of video file formats, audio and video codecs, and subtitle types.

If you are wondering what's different from mplayer2 and MPlayer you can read
more about the changes_.

Compilation
===========

Compiling with full features requires development files for several
external libraries. Below is a list of some important requirements. For
more information see the output of ``./configure --help`` for a list of options,
or look at the list of enabled and disabled features printed after running
``./configure``. If you think you have support for some feature installed
but configure fails to detect it, the file ``config.log`` may contain
information about the reasons for the failure.

Essential dependencies (incomplete list):

- gcc or clang
- X development headers (xlib, X extensions, libvdpau, libGL, libXv, ...)
- Audio output development headers (libasound, pulseaudio)
- fribidi, freetype, fontconfig development headers (for libass)
- libass
- FFmpeg libraries (libavutil libavcodec libavformat libswscale libpostproc)
- libjpeg
- libquvi if you want to play Youtube videos directly
- libx264 if you want to use encoding (has to be explicitly enabled when
  compiling ffmpeg)

Most of the above libraries are available in suitable versions on normal
Linux distributions. However FFmpeg is an exception (distro versions may be
too old to work at all or work well). For that reason you may want to use
the separately available build wrapper (mpv-build_) that first compiles FFmpeg
libraries and libass, and then compiles the player statically linked against
those.

If you are running Mac OSX and using homebrew we provide homebrew-mpv_, an up
to date formula that compiles mpv with sensible dependencies and defaults for
OSX.

Bug reports
===========

Please use the `issues tracker`_ provided by GitHub to send us bug reports or
feature requests.

Contributing
============

For small changes you can just send us pull requests through GitHub. For bigger
changes come and talk to us on IRC before you start working on them. It will
make code review easier for both parties later on.
