Re: [svn2979] Out-of-sync audio unless I resample

Thanks for the careful analysis & sample file. The bug should be fixed by r2985 . It was an ancient bug and would cause A/V sync errors any time the source rate was less than 48KHz (e.g., this was probably causing the A/V sync errors people reported for 44.1 mpeg audio in .mpg files). The reason...

Re: iPhone can now use Apple TV Preset

Yes, it works. I just converted Star Wars IV with the Apple TV preset & copied the result to my iphone GS. No complaints from itunes & it played perfectly (I double checked the settings: loose anamorphic, 8x8 dct & 3 bframes). I turned off large file size & bumped subq to 8, otherwis...

Re: "Duplicate" titles with differing audio lists

We've had other problems with the duplicate title code removing things it shouldn't . And now that you've added dvdnav support there's a way that the duplicate title removal could really mess things up: Some copy prevention schemes use post commands to define the correct play order & those comma...

Re: [svn2592] AC-3 track ignored in BBC HD transport stream

There were two bugs that kept this from working: We only looked at the first 16 streams of a program but this one has 20 & the AC-3 stream is the 20th. I upped the max number of streams we'll look at to 32. The second bug was that this stream used extended id's (a new feature introduced in the 2...

Re: ATSC TV caption support

The 708 standard is backwards compatible with 608. The ATSC DTV standard requires that the basic captions be encoded 608-compatible but "extended services" such as foreign language captions are 708-only. The change from "undefined" to "english" was an oversight. I chang...

ATSC TV caption support

This patch adds caption support for ATSC (North America) digital TV. DTV captions are harder than DVD captions. The ATSC standard limits caption data to roughly 2 characters per frame so every frame carries caption data. The caption data is in display order but the frames show up in decode order so...

The new subtitle stuff is great but I'm seeing a minor problem. I get a repeatable crash in Controller.mm after selecting "Start" when closed captions are selected. The patch at http://handbrake.fr/pastebin/pastebin.php?show=665 seems to fix the problem.

Mac display gamma change in Snow Leopard

John Gruber points out that "Snow Leopard now defaults to the same display gamma as Windows — 2.2 instead of 1.8." I hope there's good display-referenced COLR atom support in Quicktime X so this doesn't spark a whole new round of "HB's video is too dark/bright/contrasty/flat/..."

Re: another hack for NZ TV strangeness

Thanks Ed. The patch was committed as r2466. Could the reason for the PMT changes be the addition/removal of streams, since not all shows have the same streams available. And I guess maybe when they add/remove these streams they are inadvertently changing the PIDs of streams that are carrying over? ...

(the patch seems to have vanished from pastebin so I restored it as http://handbrake.fr/pastebin/pastebin.php?show=631) I guess what I'm saying is that maybe HBs assumption that the PMT is fixed for the length of a program is flawed, and that it should handle the PMT changes.

I've updated the ffmpeg patch so it applies against today's version (r19067).

I've checked that this patch gives correct preview colors on...

Re: "Genesis: The Video Show" DVD: HB only sees first chapter

All the errors were very minor John. Given the mult pgc bug in libdvdnav, none of them could have had any effect. Thanks for pointing out the pgcn bug. It should be fixed in 2423 together with a major brain-o I made in the pgc offset correction that broke previews for most DVDs.

Re: SVN2406: 1080i 60fps file 'No Title Found'

HB has to get at least one preview & it's not getting any. This is probably due to the general suckiness of Microsoft's VC-1 & not easily fixable. But you might try upping the number of previews to 20 or 30 (on the Advanced tab of the HB Prefs). If the problem is just IDR density than trying...

I bought this DVD. Its the first I've seen that uses multiple PGCs per title and, anyway, I like Genesis. Amazon delivered it today. It took a bit of hacking but HB r2420 or later should now handle it.

Re: [EDIT]Missing frames at the beginning, HB x264 file as input

Thanks for reporting this. The problem was due to broken input file chapter support. HB read the chapters in the input mp4 file then tried to seek to the start of the first chapter but the seek code computed an incorrect offset. The problem should be fixed by r2411.

Re: "Genesis: The Video Show" DVD: HB only sees first chapter

This DVD was mastered in a way that makes it impossible for HB to find the chapters. I suspect that it's using a DVD player's VM (virtual machine) commands to jump to chapters rather than following the standard & describing them in the VTS PTT. John Stebbins has very recently integrated the dvdn...

Re: mp4 to ATV conversion Audio Problem SVN2354

I downloaded the test clips from the Steve's Digicams' review of this camera. I compared the 24fps HB output with the native 30fps. It's jumpier but that's what down converting the frame rate looks like. Going from 30 to 24 means dropping 20% of the frames - 1 frame out of every 5. The current HB dr...
