Output all file names after demuxing

Hi
I have started to implement the support of DGDemux in chapterEditor(cE).
It seems there is no way to specify file names for the streams.
A global file name is used and DGDemux append some things to the file names.
It would be nice to get a list of all the file names which are created by DGDemux at the end of the Output.
Especially with the audio tracks, the file name can be very different because the DELAY is not known beforehand.
This is needed to automate all the processes in cE.
Best regards

Could you use a directory listing and RegEx search to compile that list?
I do this with Python when automating various file and folder handling, not from DGDemux specifically, but the idea should be the same. As long as you know the base name and the basic format of each possible output file (audio, video, and subs start with "[base name] PID [####]" while chapter and keyframe files are always "[base name].chapters.txt" and "[base name].qp.txt", with predictable modifications when using episode demuxing mode), you can gather and identify the list fairly easily.
This is especially simple if you use a temp/working directory where you have reasonable control over what extraneous files might exist in it at any given time.

One thing I could do easily is print lines like this:
Created for demux: filename.ext
You could see them on stdout if the -l option is not given, or see them in the output file if one is specified with the -l option.
Please let me know if that is useful for you. If so I will make a slipstream.
Still cogitating on raw M2TS list demux...

Yes that would be wonderful. The full filename (filename.ext) is fine.
The path to the temp folder is already known.

Yes I can imagine this is not so easy, please take all the time you need.

Yes of course such a workaround is easy to create and works mostly.
But I know not for cE, because sometimes I rename extracted files by adding a "_org" string and with a second demux process it is not possible to know which file was already demuxed.
And other users maybe do other things which breaks this workaround.
The best will always be, that the program sends such info via stdout.
eac3to and TsMuxeR allows to specify the filenames but I like the simpleness of DGDemux file creation.
Only missing are the created filenames.

It's a deal!
Might be easier to give the full path. Would that be an issue?

I think no. The full path is also fine, I can cut the path to get the filename only.
Only the file name would be the best, the rest is known and the output stays clean(I use often loooong folder names with many sub folders).
In my mind I would do something like this:
before you send the "Done!" string
created files:
file 1.avc
file 2.dts
etc.

OK, it shouldn't be too hard.

Much easier to output at the time the file is created, otherwise I have to store a list somewhere.

Thanks for your work. The output of the file names works but there is one issue for the "forced" sup streams.
DGDemux prints a line "Created for demux: outfile PID 1201 eng (forced).sup" but there is no such file, because there are no forced sups for that stream.
And there is another issue with DGDemux.
I have attached a chunk of the Sully Blu-ray. Mpls 00100 is the main movie.
When I use the GUI for demux, all works but when I use the CLI directly, DGDemux crashes without any info.
With the "-l" option a log file is created but it is empty.
And a Hint: I have preserved this Blu-ray as a chunk because the embedded audio stream in the TrueHD stream is an "AC3 EX" stream not a simple AC3 stream. This reports eac3to.
Code: Select all
M2TS, 1 video track, 3 audio tracks, 5 subtitle tracks, 0:00:29, 24p /1.001
1: Chapters, 10 chapters
2: h264/AVC, 1080p24 /1.001 (16:9)
3: E-AC3 EX, English, 7.1 channels, 1512kbps, 48kHz, dialnorm: -27dB
(core: AC3 EX, 5.1 channels, 640kbps, 48kHz, dialnorm: -27dB)
4: TrueHD/AC3 (Atmos), German, 7.1 channels, 48kHz
(embedded: AC3 EX, 5.1 channels, 640kbps, 48kHz, dialnorm: -27dB)
5: AC3, Hungarian, 5.1 channels, 448kbps, 48kHz, dialnorm: -27dB
6: Subtitle (PGS), English
7: Subtitle (PGS), German
8: Subtitle (PGS), Hungarian
9: Subtitle (PGS), German
10: Subtitle (PGS), Hungarian

The forced sup demuxing works nicely.
But the DGDemux.exe still crashes, only with the GUI works the demux process.
I use a simple command line:
Code: Select all
"D:\Windows\Programme\Videobearbeitung\Muxer-Demuxer\DGDemux\bin\DGDemux.exe" -i "G:\_Neues\Spectre\BDMV\PLAYLIST\00800.mpls" -o "F:\Neuer Ordner\00800\out" -demux

If I may poke my nose in here again:
If you plan to add code to check for a bare "-demux", would it possibly be about the same work but slightly more intuitive for users to have an "all" case (i.e. "-demux all")?

Please re-download once more and re-test. Be aware that bare -demux is illegal. You have to follow it with a list of streams to demux. If you want all the streams, omit the -demux option completely.

Error check was added for -demux without a stream list. Re-download.

OK. my fault and I'm not sure but I have tested it also with a PID.
However, everything works.
Many many thanks.

I fixed a crash case with a stream list so you probably hit that. Good to hear it's working. Thank you for your testing.

You and
Sherman...birds of a feather.
Thank you for your suggestion.

To me, omitting the option entirely is more intuitive, which is why it was done that way.
I think it's just a matter of people thinking because eac3to does it with a bare '-demux' then so should DGDemux.

Hmm, on second thought, why don't we just silently ignore a bare -demux and treat it as if it wasn't given. Then the eac3to syntax would work too.

OK, I slipstreamed that change into build 69. Now you can say "-demux" only and get all streams. Thank you SomeHumanPerson for (in effect) suggesting this.

That's a great (and dead simple!) solution. Well played.
