[SVN4967] Stuck PGS subtitle on Avatar Collector's edition

[RandomEngy]

On the primary title of Avatar Collector's Edition Blu-ray (length 2:58:09), the subtitle at 1:59:57 (English track #6) lingers for 10 minutes until the next subtitle. It happens in both the soft and burned-in mode.

Log: http://pastebin.com/cE7uvSAK (Yes this happens in a full encode as well)

If you need a copy of the blu-ray to fix this bug I can send you one.

This is a bit crude, but it should give an idea of what's going on:

In order to investigate, you'd need to encode from a start point before 1:59:57 to an end point after 2:09:57 (feel free to include a few extra minutes before and after for safety). I like it better when using chapters as start/end points, but that's just me. And of course, x264 ultrafast to the rescue.

There it is:

Code: Select all

[19:32:00] decpgssub: track 05, subtitle [regular]  with PTS    210210 (0 : 00 : 02)
[19:32:00] decpgssub: track 05, subtitle [empty]    with PTS        -1 (0 : 00 : 00) X

Not something I can fix, unfortunately. I'm really not familiar enough with HandBrake's A/V sync code.

Note that remuxing to MKV (via MakeMKV or otherwise) prior to encoding with HandBrake is likely to work around the issue.

Hmm, are you 100% sure this also happens with subtitle passthrough?
If so, please post a patched version's log for that too.

[RandomEngy]

I assume by subtitle passthrough you mean with "Burn In" unchecked. In that case, here's the log: http://pastebin.com/riqSLL5N

Looks like the same deal:

Code: Select all

[07:40:53] decpgssub: track 05, subtitle [regular]  with PTS    210210 (0 : 00 : 02)
[07:40:53] decpgssub: track 05, subtitle [empty]    with PTS        -1 (0 : 00 : 00) X

Have not run a full title encode in this manner however.

OK, then I guess I have to use workaround #1.

So there we go: https://trac.handbrake.fr/changeset/4970

Not as good as a proper bugfix, but better than nothing.

[RandomEngy]

Awesome! I'll try this out today.

It works! Fantastic.
