Re: AppleTV to support Dolby5.1 Natively
"VisualHub 1.31 now adds the ability to encode 5.1 surround output for output on the Apple TV. Video sources with 5.1 AC3 audio will have their audio track passed through to the finished file, according to Techspansion -- the video will be converted for optimal playback on the Apple TV." -- MacWorld

Re: AppleTV to support Dolby5.1 Natively
So for those of us who aren't able to work with the source files (aka, don't want to come crawling back to the forums when I screw something up), is there any way to get a compiled version with the new tweaks? Can someone who has compiled the latest build post a link to it? Or is that a no-no?
...understood of course that it wouldn't be an "official" release and that both stability and support would be "optional."

Re: AppleTV to support Dolby5.1 Natively
Considering how much faster iTunes adds the artwork than MetaX writes the tags I would guess iTunes is using some 'cheat' to add the pictures that doesn't work when there's just the ac3 audio track. MetaX added art works just fine. All my immediate gratification impulses concerning DD5.1 and AppleTV 2 are now satiated - now its just wait for the official release.dbendixen wrote:"new files" being the AC-3 passthrough files? I wonder what's different about the files that doesn't let the artwork stick?
Re: AppleTV to support Dolby5.1 Natively
Getting off-topic, but I think that iTunes simply saves the artwork in the database, thus not needed to rewrite the entire file. This doesn't always happen though... I've had iTunes take a couple seconds before, up to a good 5 minutes.BobVB@mac.com wrote:Considering how much faster iTunes adds the artwork than MetaX writes the tags I would guess iTunes is using some 'cheat' to add the pictures that doesn't work when there's just the ac3 audio track.

Re: AppleTV to support Dolby5.1 Natively
For a while we saw tagging issues when we intially released 6 channel discrete aac. Something about the tracks or something. Who knows.
Re: AppleTV to support Dolby5.1 Natively
Rather than use MetaX to actually inject the artwork and metadata into the mp4 file, I use the EXPORT function under the FILES menu to do a save as the same name as the movie and I find that ATVFiles and nitoTV Files both read the artwork and metadata.BobVB@mac.com wrote:Considering how much faster iTunes adds the artwork than MetaX writes the tags I would guess iTunes is using some 'cheat' to add the pictures that doesn't work when there's just the ac3 audio track.

This method also works on non-supported files, such as mov, avi, mkv, etc. (you just have to have MetaX open some mp4 file, so that its features [such as searching, etc.] will work).
Because of this I rarely, use iTunes to send over H.264 files anymore; I just send them over to the "back door," EXPORT the metadata with MetaX, and since I have another AppleTV networked to access my original AppleTV's 160Gig disk, I see the metadata and can play the files over the network.
This method also eliminates the possibility of mp4 file corruption.
Re: AppleTV to support Dolby5.1 Natively
Okay, lets keep this ship on course, this is about AppleTV and Dolby 5.1. There are plenty of threads talking about circuitous tagging methods to discuss it there. I only pointed out a working method for 5.1.
And as far as your post about VH. I am sure we are all aware of it as had been mentioned several times. Thanks for the update.

Re: AppleTV to support Dolby5.1 Natively
Oh well. A guy can hope, right? Any ETA on the next release? A few days? A few weeks? A few months?dynaflash wrote:Its a no no for the very reason you winked.
Just curious so I can plan if I should hold off encoding or not. No pressure.
The devs probably don't hear this enough, but you are VERY appreciated!
...a little sucking up couldn't hurt, right?
Re: AppleTV to support Dolby5.1 Natively
I cannot say for sure. I *can* tell you that one of the big holdups was waiting for the atv2 to find out what to do about the surround sound issue and how long it would take to get it into HandBrake. I can also tell you I am holding up on re-encoding my library for the atv. I might suggest you do the same. But of course thats up to you.
Re: AppleTV to support Dolby5.1 Natively
My test encode of Night at the Museum with the new AC3 option yielded a file that would not play in QT. Is this because they're only compatible with the ATV?
Re: AppleTV to support Dolby5.1 Natively
right now qt needs perian to play it. Like we said, its not done.
Re: AppleTV to support Dolby5.1 Natively
I want to get a charity setup for you guys. You do a lot of work for nothing. It's pretty amazing.
Re: AppleTV to support Dolby5.1 Natively
Thank you very much dynaflash... Coming from a dev rather than simple user opinion, I would say this is great advice and gives wonderful hope of things to come. Thanks!dynaflash wrote:I can also tell you I am holding up on re-encoding my library for the atv. I might suggest you do the same. But of course thats up to you.
Re: AppleTV to support Dolby5.1 Natively
I believe I read somewhere they do this for themselves Dynaflash just said he's holding off his own re-encoding process. They just "happen" to be sharing HB with the world.
I'm a dev myself, so I won't ask you guys how long before this or that, just knowing (from the test I just read about) that you've managed to get this working is great news. It'll be done when it's done. The one thing thats 99.9% sure, is that it'll be out before Duke Nukem Forever

Re: AppleTV to support Dolby5.1 Natively
I'm holding off too, but I just want to experiment a bit, well because its kinda fun and educational. The build work, so thank you again for the tips, pedvas and dynaflash. Time to have some fun with it.dynaflash wrote:I cannot say for sure.

Re: AppleTV to support Dolby5.1 Natively
I noticed in the SVN version you guys are only using one track for the audio (AC3).dynaflash wrote:right now qt needs perian to play it. Like we said, its not done.
I remember reading somewhere the apple version uses two tracks: One for AC3 and one for AAC. Is this what you mean by "working" on it? Trying to get both tracks encoded into the file?

I'm holding out hope that the iPhone will allow a file with both soundtracks (AAC+AC3) to be transferred over. A pipedream maybe...
Re: AppleTV to support Dolby5.1 Natively
Like I said .. its not done and we are working on it.
Re: AppleTV to support Dolby5.1 Natively
Simply awesome. DD 5.1 sounds superb on my 7.1 well 7.2 really since I have 2 subs. The walls rocked as they have never done before with the DPLII to DPLIIx decoding. Audio video sync worked perfectly. MetaX had no problems tagging the file at all. Great job you guys!!! This really brings ATV up to a higher level.
Re: AppleTV to support Dolby5.1 Natively
I got a "invalid sample description" in quicktime (and itunes wouldn't add) using base atv settings with the change to selecting the mp4/ac3 option using build 1265.
I'm trying a different DVD to make sure it wasn't the movie. Anyone else experience this? I know svn is not supported just curious if this is a bug or just user error on my part.
