Looking at TheBayers code it doesn't do a test that my updated code does do. That's where I made the previous code so I'm confident I'm onto the issue. I've updated my git.

If it doesn't work I'd like to see the log.

The may still be an issue with the names appearing funny I haven't looked at that one yet.

Thanks for the time you've spent on this! I thought I'd managed to replicate your issue but I was getting a slightly different error than you... Darn, back to the drawing board.

[lucasnz]

Ok, I've just updated my git. I'm pretty confident I've got the issue now. Can you let me know how that goes?

While going through all these permutations, I ran across a problem with the current version. When I checked, though, it turns out TheBayer's original code has the same issue. Digging into it a bit, it's not surprising, but it also presents something of an issue.

When the systems runs the .VOB through ffmpeg, it strips all the audio channels except for the first one. The thing is, what if the first audio track isn't the one the user wants? In most cases, it will be, but for example the first audio track for 50 First Dates is that annoying one where a couple of the actors yak away reminiscing all the things happening in the film, rather than the ordinary audio originally filmed with the video. Who in heck wants to watch that? The "ordinary" audio track is #3.

In general, one needs to be able to select the audio track at will. The best of worlds would be to transcode all the audio tracks and let the user select the one he wants on the TiVo, which does have the ability to select alternate audio tracks. Would this be possible? Alternately, we need a way to specify the audio track ffmpeg should select during transcoding in the details.txt file.

If you look at the diffs on the git the changes are very minor. The last one was a timing issue since the DVD Video plugin starts a separate thread to read the vob stream and writes this to ffmpeg. I was ending the thread before ffmpeg had received enough info... This seemed to vary from system to system or dvd to dvd. I did manage to find some that errored on mine. Perhaps my CPU is faster than yours so I didn't see the problem until now?

The question about having multiple audio track has been asked before and I believe you can transfer files with multiple tracks to the TiVo but it ignores all but the first track. You could select the audio channel with TheBayers code. I significantly improved this part of the code but I saw something in one of your log traces that indicated to me it might not work on your system (probably a problem with the regular expression used to read the audio settings. Any way put something like the following in your conf file will help select the audio track. This setting is a global setting so will work on any videos you have in your other shares as well. Basically it reads the line about the audio track and tries to find the closest match. So anything ffmpeg outputs about the audio should be able to be used to match and select a track.

[_tivo_SD]
audio_lang = en, 5.1, 6 channels, ac3

[_tivo_HD]
audio_lang = en, 5.1, 6 channels, ac3

Nope, it didn't work, even though the first stream is not ac3:

Can you please send me the log for this. As I said, I think I noted an issue earlier in one of your logs (but can't remember which one).

Yes, I agree having the option to set it "locally" as well as globally would be good. Reportedly, you used to be able to do this with TheBayers code. I'll look at adding it as a line you can specify in the details.txt...

I your opinion should the setting be per-dvd or per-track?

[lrhorer]

[lucasnz]

Ok, I've updated my git (both my main git and the DVDVideo plugin) to fix the audio track issue. So let me know how this goes for you.

There is some code in there that allows you to specify the "name" of a track (per DVD). You could use this in conjunction with the global setting to ensure the correct track get's selected. I haven't got this to work yet. So it may need some tweaking or I may just have the wrong stuff in my details.txt file. I'll let you know once I've figured this out.

I may look at adding per-track support later.

[lrhorer]

Well, there's some progress. Now it ignores track #1, which is the overdub track, but track #2 is also ac3, 5.1, so it uses it instead of track #1. Track #2 is Spanish. That's not really what I want, either.

I tried

audio_spec : Stream #0.3
audio_spec : "Stream #0.3"
audio_spec : #0.3
audio_spec : 0.3

None worked.

[lucasnz]

0x80 should work but that's not a good solution for a global setting.... You really want to set that per dvd or per track.
