Newest versions appear to have a "common.h" somewhere that is
interfering with libhb/common.h.

* sync: correct timestamp discontinuities in sync instead of reader
This patch passes discontinuity information through the pipeline till it
reaches sync.c. The timestamps are passed through the pipeline as read
and unmodified to sync.c (instead of attempting to correct
discontinuities in reader). In sync, when we see a discontinuity,
we know where the next timestamp should be based on the timestamp
and duration of the previous buffer (before the discontinuity). So
we calculate an "SCR" offset based on the timestamp after the
discontinuity and what we calculate it should be.
The old discontinuity handling code was broken due to the following.
The MPEG STD timing model relies heavily on the decoder having an STC
that is phase lock looped to the PCRs in the stream. When decoding a
broadcast stream, the decoder can count on the time measure between PCRs
using the STC to match to a high degree of accuracy.
I.e. STC - lastSTC == PCR - lastPCR. When a discontinuity occurs, the
decoder calculates a new PCR offset = PCR - STC. I.e. the offset is the
new PCR value minus what it would have been if there had been no
discontinuity.
The above does not work without a reliable STC, which we do not have.
We have been attempting to approximate one by avereraging the duration
of received packets and extrapolating an "STC" based on the last PTS and
the average packet duration. But this is highly variable and
unreliable.
* decavcodec: fix data type of next_pts
It needs to be double so that partial ticks are not lost
* deccc608sub: clarify comment
* sync: allow queueing more audio
Audio is small, and there is often a significant amount of audio in the
stream before the first video frame.
* sync: improve handling of damaged streams
When data is missing, the audio decoder was extrapolating timestamps
from the last pts before the error caused by the missing data which
caused sync issues.
Also, missing data can cause the video decoder to output a frame out of
order with the wrong scr sequence. Drop such frames.

The video frame subtitles are meant to be rendered to may not match the
actual video we are encoding. So scale to match as needed.

... instead of a 0 length buffer.
This fixes this issue:
https://forum.handbrake.fr/viewtopic.php?f=12&t=31959
Theora can create 0 length output. These 0 length frames indicate
duplicate frames. So we can't use 0 length buffers to indicate the end
of the stream.

-1 is not a good value as a flag for invalid timestamps.
There are cases where small negative timestamps are useful.
So this eliminates a potential ambiguity.

- move all subtitle hit counting to the decoders instead of reader
---> allows us to count actual subtitles rather than just packets
- always count subtitles, even when not doing a scan (may be useful in the future)
Miscellaneous improvements:
- always insert select_subtitle at the head of the output subtitle list, to make it less likely to be dropped
- when multiple subtitle tracks have forced hits, pick the track with the fewest forced hits
---> Foreign Audio Search should now work with Star Wars on Blu-ray
- logging improvements (more readable, and log job->select_subtitle configuration - Forced Only vs. All, Render vs. Passthrough)

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 ;)

vobsubs that don't have a stop time were persisting too long and being
displayed under the next vobsub in the video. We don't need to guess
the stop time of the vobsub. sync already handles unknown stop times
for subtitles.

sync.c expects that timestamps will all be resolved by the time buffers
reach it. Reader will invalidate timestamps while waiting to
resynchronize the SCR. So decoders (inparticular decvobsub) need to
extrapolate timestamps when they are not supplied.

Since we now allow subtitles that overlap in time, it is no longer
appropriate to arbitrarily set the duration to 3 seconds when vobsubs
don't have an explicit stop time. This causes them to overlap on the display.
So now, we set the stop time for such vobsubs to -1. Then in sync adjust the
stop time to the start of the next vobsub when it is seen.

Anime fans rejoice! This patch adds SSA subtitle burn-in support with libass.
Therefore SSA subtitles should now be rendered in full quality, with the
appropriate embedded fonts and positioning information.

implementation.
- Patch by davidfstr, Nice Work!
- Adds support for reading VOB subtitle tracks from file inputs.
Tested with:
- MKV VOB -> MKV VOB passthru.
- MKV VOB -> MKV VOB burned in.
VOB subtitle palette moved from per-title to per-track.

and ultimately freed twice.

- subtitles were not being added to list of subs to scan because the wrong
config was being checked for the forced flag. needed to use
job->select_subtitle_config instead of subtitle->config
- scr code in reader was preventing the majority of subtitle packets from
reaching decvobsub. made decvobsub more robust by adding ability to
re-sync in the event of lost packets. made scr recovery initialize
itself even in the event that it sees audio or subtitles before seeing
video.

- when doing an indepth scan, do not scan CC tracks
- separate subtitle configureation attributes into separate
hb_subtitle_config_t. Add an instance of this to hb_job_t for
setting the attributes of the subtitle found through an indepth scan
- Add a default_track flag to hb_subtitle_config_t that tells the muxer
that the track should be flaged as the default. muxmkv uses this.
- When an indepth scan is complete, check to see if the autoselected
subtitle matchces (by id) one of the manually selected subtitles.
If a match is found, the autoselected subtitle with all the attributes
the user assigned to it replaces the manually selected subtitle.
- LinGui: Add "Default" column to subtitle tab. This is a radio that lets
the user choose which subtitle should be displayed by default.

- new libmkv 0.6.4 with subtitle track support
- muxmkv supports vobsub and closed caption subtitles
- added subtitle format, source, and dest initialization to dvdnav
- moved subtitle_force flag into hb_subtitle_t struct as it needs to
be settable per subtitle
- gtk ui added subtitle tab which allows selection of multiple subtitles
- reorgainize subtitle sync code to prevent dropping of subtitles when
multiple subtitles are enabled
