* commit 'aa1a1b24':
  avconv: Avoid theoretical NULL dereferences

See: d768f8f5Merged-by: Michael Niedermayer <michaelni@gmx.at>

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.

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.

Fixes trac #4423.

ER with slice threads is buggy and since the merge of the libav cleanup broken
as the ER context which is supposed to be per frame has been placed in
the slice context, so there are multiple per frame which does not work as is.

Theres no bug report about ER with frame threads. If someone knows of a
case where it crashes / fails without slice threads please mail me and
open a ticket on trac.

The way it is currently designed is fundamentally unsafe and cannot be
reasonably fixed without completely rewriting it.
