John StebbinsandDiego Biurrun 8411baf6f0 dca_parser: Handle changes in DCA frame size
A change in framesize caused a perpetual loss of synchronization.
So read (and use) the frame size from the frame header instead of
setting it only once.

John StebbinsandAnton Khirnov 26b241c079 matroskaenc: Allow chapters to be written in trailer
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.

John StebbinsandAnton Khirnov f812eeda17 matroskaenc: Fix writing TRACKDEFAULTFLAG
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.

John StebbinsandAnton Khirnov 30ce289074 movenc: Make tkhd "enabled" flag QuickTime compatible
QuickTime will play multiple audio tracks concurrently if this flag is
set for multiple audio tracks.  And if no subtitle track has this flag
set, QuickTime will show no subtitles in the subtitle menu.

for example:
Attempting to set ac3 dsur_mode to "on" results in:
[AC-3 Encoder @ 0x7f508f0a3280] Value 2.000000 for parameter 'dsur_mode' out of range

John StebbinsandRonald S. Bultje 0d802ac54e vc1: fix VC-1 Pulldown handling.
Pulldown flags are being set incorrectly and AVFrame->repeat_pict is not
being set.  Also, skipped frames exit header parsing too early and do not
set pulldown flags appropriately. Ticks_per_frame needs to be set and
time_base adjusted so player can extend frame duration by a field time.

This fixes problems encountered when attempting to transcode HD-DVD EVOB
files with HandBrake. Also makes these files play smoothly in avplay.

John StebbinsandRonald S. Bultje 49c7006c7e dca: set AVCodecContext frame_size for DTS audio
Set the frame size when decoding DTS audio.

This has the side effect of fixing the computation of timestamps for DTS-HD in compute_pkt_fields.  Since frame_size is
not currently set, the duration of a frame is being guessed based on the streams bitrate.  But for DTS-HD, the bitrate
currently used is the rate of the DTS core which is much different than the whole DTS-HD stream and leads to a wildly
inaccurate frame duration estimate.

John StebbinsandRonald S. Bultje cdc2c1c576 matroskadec: matroska_read_seek after after EBML_STOP leads to failure.
EBML_STOP leaves matroska->current_id set. Then matroska_read_seek changes
the stream position without resetting current_id.  The next
matroska_parse_cluster  fails due to calculation of incorrect pos.  So clear
current_id when avio_seek happens in matroska_read_seek.

John StebbinsandLuca Barbato 98a7d560b4 matroskadec: set default duration for simple block
When a normal Block is parsed, duration is initialized to
AV_NOPTS_VALUE.  If it is not changed, then the track's default
duration is used.  But for SimpleBlock, duration is initialized to
0 instead of AV_NOPTS_VALUE.  This is due to the difference in how
EBML_NEST vs EBML_PASS are processed.  Setting duration to 0 leads
eventually to wrongly estimate the frame duration in util.c
