Although it's not allowed to use only allows 'nclc' in ISOM files, there
are samples that do not always respect this rule. This change prevents
atom overread and a spurious color range initialization.

MicroDVD has a "hack" for specifying the video framerate the subtitle
was authored against. The demuxer reads this hint correctly, but didn't
skip it correctly.
This was not noticed, because the exported packet has its duration set
to 0, making it invisible (depending on the API user's rendering logic).

Generally, libavformat exports cover art pictures as video streams with
1 packet and AV_DISPOSITION_ATTACHED_PIC set. Only matroskadec exported
it as attachment with codec_id set to AV_CODEC_ID_MJPEG.
Obviously, this should be consistent, so change the Matroska demuxer to
export a AV_DISPOSITION_ATTACHED_PIC pseudo video stream.
Matroska muxing is probably incorrect too. I know that it can create
broken files with an audio track and just 1 video frame when e.g.
remuxing mp3 with APIC to mkv. But for now this commit does not change
anything about muxing, and also continues to write attachments with
AV_CODEC_ID_MJPEG should the muxer application have special knowledge
that the Matroska is broken in this way.

MSVC does not support the %F and %T format specifiers in strftime.
Replace that with the expanded version. This fixes the broken fate
tests in MSVC (webm-dash-manifest-*).

This patch adds support for WebM Live Muxing by adding a new WebM
Chunk muxer. It writes out live WebM Chunks which can be used for
playback using Live DASH Clients.
Please see muxers.texi for sample usage.

This patch adds support for parsing live files (produced by
-f webm_chunk) which contains only the headers but no packets. This
is only used when using -f webm_dash_manifest. There will be a
follow up patch which adds live support to WebM DASH Manifest
muxer.

I found another MXF File containing ProRes with the following

Therefor I relaxed the pattern.

Make sure we don't buffer up more than max_delay worth of data

The AVSC_API changes in the new headers mean that the 2.6 alphas

In order to safely exit when the user tries to use AviSynth 2.5,
the continue_on_fail value for 2.6's functions need to be set to
1. Otherwise, the library loader fails before the 'upgrade to
2.6' log message appears.
