sync needs the precise duration of a frame of audio and has
no way to compute it for passthru audio. So add a duration
member to hb_buffer_t and set it in the audio decoders.
This should eventually supersede hb_buffer_t member "stop"
since it provides redundant information.

Thanks to patches supplied by David Mitchell and Rob McMullen
we finally have PGS support.
I added a fix for libav pgs timestamp processing and
detection of forced subtitles to their work, then
made foreign audio search work with PGS subs.

when frames are duplicated, the frame was not copied properly and resulted
in divide by 0 later when the frame is processed.
This fix is a bit larger than the minimum size necessary to fix the problem.
I took the oportunity to clean up some buffer initialization and copy
operations.

This patch enhances the filter objects. The 2 key improvements are:
1. A filter can change the image dimensions as frames pass through it.
2. A filter can output more than one frame.
In addition, I have:
Moved cropping & scalling into a filter object
Added 90 degree rotation to the rotate filter
Moved subtitle burn-in rendering to a filter object.
Moved VFR/CFR handling into a framerate shaping filter object.
Removed render.c since all it's responsibilities got moved to filters.
Improves VOBSUB and SSA subtitle handling. Allows subtitle animations.
SSA karaoke support.
My apologies in advance if anything breaks ;)

Specifically, this affects closed captions which are pushed into the
pipeline very late. CC's are dribbled in 2 bytes per video frame.
The entire CC that we put into a subtitle frame isn't available till
we see the signal for the end of the CC. This can be several seconds
after it began. So I have established a minimum buffer size that the
muxer accumulates before it outputs any data. This allows CCs to get
into the pipeline before the muxer outputs the interleave interval that
they belong in.

The AVCHD-Lite specification only supports 50 or 60 fps. So to get
25 or 30 fps, they double every frame using repeat flags. Detect
this and adjust the framerate accordingly.

Seek point may be a recovery point which will not be a complete clean
frame. So consume frames till we reach the recovery frame count.
Patches Libav so it can tell us when the recovery point has been
reached.
Also improves detection of recovery points in TS files.

Many transport streams have few or zero IDR frames. So scanning them
takes a long time, generates a lot of log spam, and results in poor
preview quality. Often there will be several identical preview frames
because it will find the same IDR for several of the previews. Using
recovery points helps all these problems.

For files that are demuxed by Libav, we must share the format context
with the decoder iso that it can obtain the codec context for each stream.
The code that did this was very convoluted and difficult to understand.
It is simplified by simply passing the context in hb_title_t.
Reader was closing stream files before the decoder was finished with the
context. This created the need to delay the actual close and cache
the context. Changed reader so it behaves more like the rest of handbrake's
work objects which lets us explicitly close after the decoders are finished.
Libav does some probing of the file when av_find_stream_info is called.
This probing leaves the format context in a bad state for some files and
causes subsequent reads or seeks to misbehave. So open 2 contexts in
ffmpeg_open. One is used only for probing, and the other only for reading.
decavcodec.c had 2 separate decoders for files demuxed by hb and files
demuxed by Libav. They have been combined and simplified.
Previously, it was not possible to decode one source audio track multiple
times in order to fan it out to multiple output tracks if the file is
demuxed by Libav. We were using the codec context from the format context.
Since there is only one of these for each stream, we could only do one
decode for each stream. Use avcodec_copy_context to make copies of
the codec context and allow multiple decodes. This allows removal of
a lot of special case code for Libav streams that was necessary to
duplicate the output of the decoder.
Patch Libav's mkv demux to fix a seek problem. This has been pushed
upstreams, so the next time we update Libav, we must remove this patch.

for any audio encoder that libav supports. Since ffaac is not quite
ready, the cli and gui does not expose ffaac yet.

TrueHD and DTS-HD now show up in the audio list along side their
AC-3 and DTS counterparts.
Note that currently the DTS-HD decoder we are using (ffmpeg) discards
the HD portion of the stream and onle decodes the DTS core portion. So
there is no advantage yet to using the DTS-HD stream. In the future
I would like to add DTS-HD passthru support and hopefully ffmpeg will
improve their DTS-HD decoder.

These boundaries are always discontinuities. But sometimes we were
not detecting them as such and would drop frames. So set a flag
in the buffer when libbluray tells us a new clip is starting and
use that to trigger computation of a new scr offset.

* New subtitle sync algorithm added to sync work-object ("simultaneous").
Classic algorithm preserved but disabled.
* Render work-object now supports queueing a /list/ of subtitles.
* FIFOs have been extended to support pushing/popping buffer-lists as single elements.
* Added SUBSYNC_VERBOSE_TIMING flag to debug timing issues related to subtitle display.
Observable behaviors changed in the new subtitle sync algorithm:
* Temporally overlapping subtitles are no longer trimmed to be non-overlapping.
* Subtitles less than two seconds long are no longer artificially extended. Sorry, Indochine fans.
* Subtitles that stop before they start will never be displayed. The old algorithm will display such subtitles if they begin in the future (relative to the current video frame being processed).

Therefore SSA subtitles should now be rendered in full quality, with the

Unencrypted BD directory trees only. Doesn't support iso images.
Also, no PGS subtitle support yet.
Chapters and angles are supported.
Adds a new contrib libbluray.
Adds new option to hb_scan() for duration of short titles to filter.
This applies to BD and DVD multi-title scans only. Does not apply
to any single title scans.
Fixes memory leak during scan. hb_buffer_close() was not freeing
all buffers in a chain of buffers passed to it.

when a button press leads to a title, i check to see if it is the
longest seen thus far and save it's index.
this only applies when dvdnav is enabled. when dvdread is in use,
the longest title of all the titles is flagged as the "main feature"

the current audio buffer was being dropped when silence was inserted, causing
the time to fall even further behind and provoke more silence insertion
in some cases.
with pont-to-point, it is possible for one stream to complete before the
other(s). when the work_loop exits for that stream, the fifo is no longer
serviced and may fill. This can back up and cause a stall in reader
causing the streams that are not yet complete to stall. The Solution is
to continue servicing the fifo after work for a stream is complete. This was
complicated by the fact that the video sync work object was being used as the
indicator that all work was finished. When it exited everything was told
to stop. So now, the muxer work object (last in the chain) is the
indicator when work is done.

audio frames can be larger than their container packet sizes, but during
scan, we only feed one container packet to the decoder, then reset
the decoder and try the next packet. so the audio is never detected.
as buffers are tested, they are added to a cache. the entire cache is
passed to the decoder to scan for info. the cache is limited to 4KB.

New job variables pts_to_start and frame_to_start specify the start point.
There can be a period during the encode where it has to search for
the start point. During this period, libhb sets a new state
HB_STATE_SEARCHING and sets progress and eta till start point found.

pthread_cond_timedwait can wake early. under certain system load conditions, this
happens often. I was going ahead and adding buffers whenever it woke, regardless
of whether the condition had actually been met. so the fifo depth would
increase until memory ran out.

pipeline
For HD sources on an 8 core system with hyperthreading, we were using 1.5GB
of ram. Add to that the 600MB x264 uses for rc-lookahead, pushes it north of 2GB.
To reduce our memory usage, the fifo depths have been reduced are are no longer
a multiple of cpu count. Use of hb_snooze has been eliminated in the encoding
pipeline so that performance doesn't fall as a result of the reduced fifo depths.
In sync, each audio and video were given separate threads so that each can wait on
it's respective input fifo without blocking the others. In muxcommon, each stream
being muxed was given a separate thread so that each can wait on it's respective fifo.
This allows the removal of hb_snooze in the sync and muxer work loops. In both sync
and muxer, there is common data that is shared by all threads, so special init
routines allocate this shared data and initialize the threads.

then if that fails, we attempt to open each file in the directory as a stream
source. Since opening a large directory of files can take a really long time,

crc) rather than looking at multiple frames. This should reduce the probability of mis-identifying random junk as AC-3 to less than 1 in 2^32.
- check the crc on every frame so we don't let corrupted data into the decoder.
- interpret the PTS as per the standard (it's the time of the first frame that starts in the packet, not the time of the first byte of the packet). Incorrect interpretation was resulting in an average 15ms timing error (worse case 31ms).
- do all the PTS calculations in doubles so we don't get round-off error that will desync the audio & video with 44.1KHz audio sources (these can't appear on DVDs but do show up in avi/mkv/... files).
- don't rely on the container to give us large enough frame fragments to validate the sync (some containers split audio frames into really small pieces). Instead use the 8K of unused space in the esconfig of the audio object as an accumulation buffer.
