* sync: correct timestamp discontinuities in sync instead of reader (#192)John Stebbins2016-05-241-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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.
* sync: fix merging of multiple SSA to tx3gJohn Stebbins2016-05-171-4/+4
| | | | | | When more than 2 subtitles overlapped in time, they were not merged properly and could result in cases where the subtitle time went backwards

* libhb: add hb_buffer_listJohn Stebbins2015-09-241-39/+8
| | | | | This brings together several independent implementations of a simple buffer list manager.
* 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

* deccc608: fix rollup style CC problemsjstebbins2014-09-261-37/+36
| | | | | | | | | | | | The timing of the "erase display" command was incorrect for rollup CC and erased subtitles immediately after they were displayed. When rendering, sometimes rollup subtitles arrived at the renderer far after the frame they should be rendered on. So push rollup subtitles into the pipeline for each new character received when rendering. git-svn-id: svn://svn.handbrake.fr/HandBrake/trunk@6421 b64f7644-9d1e-0410-96f1-a4d463321fa5

| | | | | | | | | | | | Thanks to patches supplied by David Mitchell and Rob McMullen we finally have PGS support.

* Rework filter pipelinejstebbins2012-03-271-6/+6
| | | | | | | | | | | | | | | | | | | | 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
