QuickTime 7.5.5 is out

[thewolfe]

http://www.apple.com/quicktime/download/

will check tonight to see if it fixes the digital passthrough that 7.4.5 broke.

[gbooker]

Perhaps, we can hope, however futile it might be, that the real passthrough method is actually enabled; like it was on the ATV.

[thewolfe]

passthrough via perian is still borked

/sigh

[gbooker]

Works here.

What, exactly, is your test case?

[Push Eject]

I was the guinea pig last time...

Gbooker, you know I love you, but boy I wish we understood why this works for you and not for some of us!

I will image my mini and try the upgrade as well. If someone beats me to it, please post your results!

Cheers,
Push E.

[Harriet1]

Everything is working again for me, just made sure I went through each step of the setup and made sure I was using the optical out, restart. It's great when these things work.

Good luck everyone else.

G5 2.3 everything up to date

Should have mentioned that before I changed ~/Library/Preferences/com.cod3r.a52codec.plist I tried with all other setting enabled DD jumped in the back out to stereo. This my mean things are changing. Also when playing AC3 DD passthrough any other audio played breaks it sending it back to white noise, make sure you have no other audio playing.

Harriet, that's great to hear.

Can I assume that 7.5 DID break ac3 for you as it did for many of us? If so then your post is very encouraging.

...when playing AC3 DD passthrough any other audio played breaks it sending it back to white noise, make sure you have no other audio playing.

That makes perfect sense as ac3 is a bitstream of data. Anything that affects that stream; other data, volume other than 100%, etc... would make the stream invalid and undecodeable.

Can't wait to try the upgrade out myself!

What, exactly, is your test case?

What I meant by this is, what kind of files are you trying? Is it a .mov ripped with Handbrake, an AVI file, a .ac3 file, mkv, etc? Some of these will work, and one will not due to one of Apple's bugs (filed a rdar about it several months ago, and was subsequently ignored, as usual).

Handbrake m4v (H.264 + AC3)

defaults write com.cod3r.a52coded attemptPassthough 0, results in playback in Stereo
defaults write com.cod3r.a52coded attemptPassthough 1, results in loud painful hurting sound

That's what undecoded ac3 sounds like... I am saddened. Sounds like 7.4.1 might be the place to stay.

Harriet, what are you using for a container and format?

Handbrake m4v (H.264 + AC3)

rdar 5799879 (opened March 14th, no response from Apple). That's the problem, in it's entirety. Here's the text:

Code: Select all

The channel layout used by QT's built in 'eat ' 'ac-3' is inconsistent with Core Audio's default channel layout.  From: http://developer.apple.com/documentation/MusicAudio/Reference/CAFSpec/CAF_spec/chapter_3_section_5.html in the channel layout chunk section, it states that if the channel layout is set to use the bitfield, the order is the same as order of the bits set (low order first).  This means the layout is:
L R C LFE Ls Rs Cs (missing channels skipped).

The layout used by the built in importer for a 5.1 ac3 file is:
L C R Ls Rs LFE (kAudioChannelLayoutTag_MPEG_5_1_C)

The layout should be consistent with the CA default channel layout, especially since the only multi-channel AC3 decoder that I know of for CA/QT (A52Codec) assumes this layout.  For reference, this is:
Channels      w/o LFE                        w/LFE
Mono         kAudioChannelLayoutTag_Mono      N/A
2F            kAudioChannelLayoutTag_Stereo      kAudioChannelLayoutTag_DVD_4
3F            kAudioChannelLayoutTag_ITU_3_0      kAudioChannelLayoutTag_DVD_10
2F1R         kAudioChannelLayoutTag_ITU_2_1      kAudioChannelLayoutTag_DVD_5
3F1R         kAudioChannelLayoutTag_ITU_3_1      kAudioChannelLayoutTag_DVD_11
2F2R         kAudioChannelLayoutTag_ITU_2_2      kAudioChannelLayoutTag_DVD_6
3F2R         kAudioChannelLayoutTag_ITU_3_2      kAudioChannelLayoutTag_ITU_3_2_1

Note: These can all be kAudioChannelLayoutTag_DVD_* formats, but the ITU constants are more descriptive where they exist.

Handbrake m4v (H.264 + AC3)

rdar 5799879 (opened March 14th, no response from Apple). That's the problem, in it's entirety.

Thanks for the info, and I figured something was up when you asked what the format was.

Out of curiosity, since you say passthrough working for you, what format are you saving your files in?

[gbooker]

Out of curiosity, since you say passthrough working for you, what format are you saving your files in?

I was testing .ac3, avi, and mkv, along with .mov files not made by handbrake or apple. I skipped the last two due to the aforementioned bug.

[Harriet1]

I must apologise it is only working with mov(mp4 + AC3) not Handbrake m4v (H.264 + AC3)

I'll research better next time.

Hi there,

I have just updated my brand new Mac Mini to QT7.5.5.and Front Row 2.1.6 and I have 1 season of BSG season 4 that are mkv's with 1280 x 720 pixels .H264 encoded video packed in an MKV with an AC3 audio track.

Playback in Quicktine or Front Row is extremely choppy, but AC3 PASSTHROUGH IS WORKING!

Playing the same file in Plex is a breeze!

Hope this will help anyone out there...

Regards,
Jasper

[Push Eject]

Jaspers, can I assume you have Perian 1.1 installed?

[ivalegre]

The only that works wrong is Subtitle support. Quicktime 7.5.5 + Perian 1.1 doesn't load SRT subtitles.

How can I solve this?

I tried this but nothing changes.

I'm from Spain and I need Subtitles to see USA TV Series. Meantime I use VLC but I prefer Quicktime+Perian.

Thanks

Handbrake m4v (H.264 + AC3)

defaults write com.cod3r.a52coded attemptPassthough 0, results in playback in Stereo
defaults write com.cod3r.a52coded attemptPassthough 1, results in loud painful hurting sound

Almost right.. Just a few typos and wrong value type. Here the same with some corrections:

Code: Select all

defaults write com.cod3r.a52codec attemptPassthrough -int 0   # playback in stereo, works fine
defaults write com.cod3r.a52codec attemptPassthrough -int 1   # "binary" audio


or just open Property List Editor and edit ~/Library/Preferences/com.cod3r.a52codec.plist to have a key (child) under Root that is named as "attemptPassthrough" and has a "number" -type value (class).

That works for me. Tested on 10.5.4-5, intel & PPC. My movie.m4v is ripped and encoded with Handbrake to H264 video with AC3 audio. I just upgraded QT to 7.5.5 and it didn't help to that H264+AC3 problem, unless I had AC3 passtrough disabled. Almost missed a movie this night Without that com.cod3r.a52codec.plist -file your audio should be fine, but just 2.0. Haven't tried disabling passthrough before 7.5.5 thou. Perian is v1.1.

HTH

Today's Perian build from svn source seems to have finally fixed the iTunes 8 startup crash problem. I still am getting a crash with QuickTime 7.5.5 when trying to play some matroska videos, below is the stack from the problem report:

I need the original file to look at this (or the first 5-10MB if that's enough, see http://ffmpeg.mplayerhq.hu/bugreports.html).

Subtitles work for me with either SVN or 1.1. If they don't work for someone, does the track still appear in cmd-I or not?
