Muxing in 5.1 AC3 audio ends in the audio being halved #331

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Open a new Subler window and drag in an .mkv with Apple TV 2-compatible 
video (tested separately) and select only the video track
2. Convert the 5.1 DTS audio elsewhere to 5.1 AC3 and drag this in to the window
3. Mux the two streams together (but don't cross them, as per the advice of the 
Ghostbusters!)

What is the expected output? What do you see instead?
I'd expect the finished file to have 5.1 surround. Instead, bizarrely, the 
resulting file seems to have halved the number of audio channels. Subler 
displays the audio's correct length, but indicates that it has 'AC-3, 3 ch'. 
I've checked the streams in another application to ensure it wasn't simply a 
display error, but it does seem to have done this. Needless to say, the files 
don't play on the ATV 2.

What version of the product are you using? On what operating system?
Subler 0.14, on Mac OS 10.5.8.

Please provide any additional information below.
I suppose this may well be related to the architecture I'm running Subler on 
(PPC rather than an Intel mac), but I've just gotten the hang of using Subler 
for remuxing MKVs and so it'd be cool if this was the result of a bug rather 
than a limitation of ffmpeg or something like that.

It might be a ppc only bug. I'll check today later.

Thanks for looking into it for me. If you'd like me to provide logs or anything 
like that, let me know (either here or via email/etc). :)

I found an issue where Subler read the channel number only for the first .ac3 
imported, and then reuse it.
I can't test on ppc because I've got no ppc mac and I'm on lion.

You could try a previous version, probably it'll work.

Hey. I tried about six or seven older versions, and they all do the same thing. 
Are there any log files I could send you that might help you make sense of it?
