Fixes https://github.com/HandBrake/HandBrake/issues/685
For some stream types, libav does not seek all streams within the file
to the same position. So we get data from streams that is prior to the
desired preview start position leaking through. The result, for example,
is a preview that has audio that starts from the beginning of the file
and video that starts much later at the desired start pos.

Reader can skip data at the beginning of the file. We were not
informing decsrt how much was skipped when pts_to_start caused the skip.

* 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 angle can affect the seek position
|
| |
|
|
|
|

This broke when sync was reworked. Sync now expects job->pts_to_start
to be relative to the first frame that it sees.

Don't use hard coded 100 fifo array, allocate what is needed.
We probably just crashed if the number of tracks was > 99 since the
limit of 100 fifos was not universally checked.

We split PES packets when there is a PCR change in the middle of the
packet. This works fine for audio and video where the decoder parses
the ES to find frame boundaries. But it does not work for some decoders
such as PGS subtitles. So mark split buffers and reassemble them in
reader after processing the PCR change.

simplify job initialization sequence, clean up code, and document
dependencies in the sequence better.
Make hb_add set job->sequence_id. It is no longer necessary for the
frontend to do this. If the frontend needs the sequence_id, it is
returned by hb_add().
Clean up use of interjob. do_job() now uses sequence_id to detect when
a new sequence of related jobs is running and automatically clears
interjob.

This brings together several independent implementations of a simple

... 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.

We must set a start time for subtitles or the vobsub decoder (and probably
other subtitle decoders) will assign duplicate timestamps. So when a
discontinuity occurs, make the closest guess that we can.

This global was shared between the CLI and libhb and used as a back door to
force scan and encode passes to use the same ffmpeg context for hardware
decoding. Aside from the fact that this context sharing should not be necessary
and needs fixing, this information belongs in the hb_handle_t that is shared
between the scan and the encode. So put it there and make sure the hb_handle_t
get propagated to where the flag is needed.

Simplifies the WinGui.
This also changes how jobs are processed. Creating the sub-jobs for
multiple passes is delayed until after scanning and immediately before
running the job.
Working status has also changed. Sub-job passes are identified in status
with an ID that allows the frontend to definitively identify what pass
is in progress.

The primary problem was in setting our "zero" time in reader based on a
stream that is not decoded. Since this stream never reaches sync, there
would appear to be a long initial frame from syncs perspective.

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

frames. this leads to an over-cunsumption of memory since all duplicates
are placed in a list at once.

Cleans up several several unavoidable memory leaks caused by old api.
Clearly separates titles from jobs. Titles are set during scan and
never modified now.
Since titles are immutable, this lead to API some changes. For example,
We were setting chapter names in the title from the front ends. Now
these get set in the job.
These new APIs allow us to start moving away from our use of title->job.
Eventually, I would like to eliminate title->job completely, but the
mac ui is too tightly tied to using this field to allow removing it
at this time. So there is temporarily a convenience function used
only by the mac ui that allows it to continue using title->job and also
use the new APIs.
New APIs:
typedef struct hb_title_set_s hb_title_set_t;
struct hb_title_set_s
{
hb_list_t * list_title;
int feature; // Detected DVD feature title
};
hb_title_set_t * hb_get_title_set( hb_handle_t * );
This is just something I added to clean up how "feature title" info
is passed.
hb_job_t * hb_job_init( hb_title_t * title );
Initializes a new job with default settings from the title.
hb_job_t * hb_job_init_by_index( hb_handle_t *h, int title_index );
Same as hb_job_init(). For use by win Interop lib.
void hb_job_reset( hb_job_t * job );
Convenience function for the MacUi.
Clears audio, subtitle, and filter lists. The macui still uses
title->job because it is so intricately tied to it. So I created
this convenience function that it can call after adding a job.
void hb_job_close( hb_job_t ** job );
Releases the job an all resources it contains.
void hb_job_set_advanced_opts( hb_job_t *job, const char *advanced_opts );
Makes a copy of "advanced_opts" and stores in job.
Freed by hb_job_close().
void hb_job_set_file( hb_job_t *job, const char *file );
Makes a copy of "file" and stores in job.
Freed by hb_job_close().
void hb_chapter_set_title(hb_chapter_t *chapter, const char *title);
Makes a copy of "title" and stores in chapter.
Freed by hb_chapter_close().
Recommended usage (cli and lingui are updated to do this):
job = hb_job_init( title );
// set job settings ...
hb_add(h, job);
hb_job_close( &job );
I have also added new APIs for managing metadata. These are
used to add metadata to a job.
void hb_metadata_set_name( hb_metadata_t *metadata, const char *name );
void hb_metadata_set_artist( hb_metadata_t *metadata, const char *artist );
void hb_metadata_set_composer( hb_metadata_t *metadata, const char *composer );
void hb_metadata_set_release_date( hb_metadata_t *metadata, const char *release_date );
void hb_metadata_set_comment( hb_metadata_t *metadata, const char *comment );
void hb_metadata_set_genre( hb_metadata_t *metadata, const char *genre );
void hb_metadata_set_album( hb_metadata_t *metadata, const char *album );
void hb_metadata_set_coverart( hb_metadata_t *metadata, const uint8_t *coverart, int size );
Example:
job = hb_job_init( &job );
// set job settings ...
hb_metadata_set_artist( job->metadata, "Danny Elfman" );
hb_add(h, job);
hb_job_close( &job );
Some APIs have changed in order to avoid using title incorrectly and
use the new hb_title_set_t.
-void hb_autopassthru_apply_settings( hb_job_t * job, hb_title_t * title );
+void hb_autopassthru_apply_settings( hb_job_t * job );
-void hb_get_preview( hb_handle_t *, hb_title_t *, int, uint8_t * );
+void hb_get_preview( hb_handle_t *, hb_job_t *, int, uint8_t * );
hb_thread_t * hb_scan_init( hb_handle_t *, volatile int * die,
const char * path, int title_index,
- hb_list_t * list_title, int preview_count,
+ hb_title_set_t * title_set, int preview_count,
int store_previews, uint64_t min_duration );
These APIs have been removed. Win Interop will need some changes.
I think what I've provided will be suffecient, but let me know if it's not.
-void hb_get_preview_by_index( hb_handle_t *, int, int, uint8_t * );
-void hb_set_anamorphic_size_by_index( hb_handle_t *, int,
- int *output_width, int *output_height,
- int *output_par_width, int *output_par_height );

- 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)

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 ;)

For TS streams that don't have PCRs, we substitute the DTS timestamp
from the video track (or PTS if we don't see DTS). But these can bounce
around or be wider spaced in the stream that PCRs are meant to be. So I
have added a test to see if the timestamp looks like a discontinuity.
Then I only pass the timestamp as a PCR if there appears to be a
discontinuity. This prevents a lot of scr_offset thrashing.
I have also fixed an error in our scr_offset processing. It is rarely
triggered and it's effects are so minor with well behaved streams that
it would be completely unnoticed. But with the test stream I was using,
it caused a factor of 10 times more "audio went backwards" errors.

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.

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.
