* sync: correct timestamp discontinuities in sync instead of reader (#192)John Stebbins2016-05-241-34/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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.

* libhb: Use a buffer flat to indicate EOFjstebbins2015-05-011-1/+1
| | | | | | | | | | | | ... 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. git-svn-id: svn://svn.handbrake.fr/HandBrake/trunk@7143 b64f7644-9d1e-0410-96f1-a4d463321fa5

* Rework filter pipelinejstebbins2012-03-271-285/+56
| | | | | | | | | | | | | | | | | | | | 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 ;) git-svn-id: svn://svn.handbrake.fr/HandBrake/trunk@4546 b64f7644-9d1e-0410-96f1-a4d463321fa5
* Fix parsing of SSA layer fieldjstebbins2011-09-241-5/+33
| | | | | | | | | | | | SSA subtitles have an empty layer field (bare ','). The scanf format specifier "%*128[^,]" will not match on a bare ','. There must be at least one non ',' character in the match. So the format specifier is placed directly next to the 'Dialogue:' string so that the next expected ' ' after the ':' will be the character it matches on when there is no layer field. git-svn-id: svn://svn.handbrake.fr/HandBrake/trunk@4244 b64f7644-9d1e-0410-96f1-a4d463321fa5

* Add temporally overlapping subtitle support.davidfstr2011-02-251-0/+6
| | | | | | | | | | | | | | | | | * 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). git-svn-id: svn://svn.handbrake.fr/HandBrake/trunk@3804 b64f7644-9d1e-0410-96f1-a4d463321fa5
