Looks like it's working.

Done!

Will try on Arch soon.

One small thing: "./dgdemux -i" leads to "Segmentation fault" error. Probably it's good to add extra check if option is not empty or so.

Done!

So it work on Arch as well.

Works also in WSL (ubuntu) over SMB here.
You can mount network drives with

Code: Select all

sudo mount -t drvfs '\\NAS\my_bd\' /mnt/bb

Code: Select all

./dgdemux -i /mnt/bb/BDMV/PLAYLIST/00001.mpls

EDIT:
No progress indicator?
Is it possible to add a --help parameter that shows the available parameters?

Thank you DJATOM for your test results.

Yeah, I'll tighten up the error checking.

Thank you thechaoscoder for your testing.

How do you want the progress to be indicated?
--help would be useful.

Posted: **Sun May 09, 2021 2:01 pm**

For example, it might be done like that

Code: Select all

while(percents != 100) {
    fprintf(stderr, "%d% done\r", percents);
    // also you can sleep this loop for 250-500 ms to don't eat up resources too much
}

Sounds good, thank you.

Removed dgdemux.gz as I want to replace it with the completed version. Still need:

* Preallocation
* Episode demuxing [COMPLETED]
* Better command line syntax checking [COMPLETED]
* --help [COMPLETED]
* Progress indication
* Appropriate version number [COMPLETED]

Posted: **Tue May 11, 2021 12:58 pm**

@DJATOM

DJ, do you think preallocation is a big deal? Should I try to find a portable way to do it for linux?

I think it's not a big deal. And using falloc on FAT32 or ext3 might block application entirely for a long time, not sure if it's really beneficial at all. Fragmentation is not really an issue nowadays, modern OSes are smart enough to handle that when PC idling.

Posted: **Tue May 11, 2021 2:16 pm**

OK, thank you, I will nuke it.

Posted: **Tue May 11, 2021 4:20 pm**

If I may,
with SSD prices dropping and capacity increasing (normally) fragmentation really isn't much of an issue

Posted: **Tue May 11, 2021 7:35 pm**

That settles it then. gonca has spoken!

Posted: **Wed May 12, 2021 10:00 am**

Here is a release candidate for DGDemux linux version. Your testing will be appreciated.

* Implemented episode demuxing -ep.
* Changed -nopre option to -pre, i.e, inverted its sense. -pre will
return a 'currently not implemented' error for now.
* Implemented -h (help) option.
* Implemented -v (version) option.
* Better error checking on the command line.

Progress indication is not yet implemented.

Tested -ep on my end, it works.

Posted: **Wed May 12, 2021 10:32 am**

Thank you, DJ!

I'm going to try bringing up VS Code today.

Got the stupid taxes done. Robber barons!

Posted: **Wed May 12, 2021 11:22 am**

From help text (-h)
-l path_to_file: ... "You can also use it to discard the output when using DGDemux.exe directly:"

I think you missed one ".exe"

I just made a simple build script that makes .deb package. I think it's not bad to provide it, people with less Linux knowledge can install it in one click (or command). So that's a convenience for them.

Code: Select all

#!/bin/sh

rm -rf debian

mkdir -p debian
mkdir -p debian/DEBIAN
mkdir -p debian/usr/local/bin

version=$(./bin/dgdemux -v | grep -Eo 'DGDemux ([0-9\.]+)' | grep -Eo '([0-9\.]+)')

echo """Package: dgdemux
Version: ${version}
Section: utils 
Priority: optional
Architecture: amd64
Essential: no
Depends: 
Pre-Depends: 
Recommends: 
Suggests:

Description: DGDemux is a standalone demuxer for BluRay/UHD disks, including 3D BluRays. It takes a playlist and demuxes all the elementary streams (audio and video), the subtitle streams, and the chapters. The demuxed files are all in sync with the demuxed video, even for seamless branching titles.""" > debian/DEBIAN/control

cp bin/dgdemux debian/usr/local/bin
chmod +x debian/usr/local/bin/dgdemux

dpkg -b debian dgdemux_${version}.deb

If you willing to provide packages, put that script into certain folder (for example, folder name "dgdemux-package", script name "mkdeb.sh") and set execution rights (chmod +x mkdeb.sh). Put dgdemux binary into "dgdemux-package/bin" and run script. It should produce dgdemux_1.0.0.50.deb (current version) which you can host as alternative to .gz archive.

Great, thanks!

Posted: **Wed May 12, 2021 9:33 pm**

We're allowed to be stupid, right? Do we have to make a RPM distribution as well as a DEB one?

Posted: **Thu May 13, 2021 12:36 am**

I don't have any experience with rpm to say for sure

Posted: **Fri May 14, 2021 9:43 am**

OK, I'll just distribute raw binaries for now.

VS Code appears adequate for debugging. Better than printf debugging at least.

I have it working fine. Still lots to learn about it but good for now. Thank you for the heads up, DJ.

What shocked me was how fast all the vi commands came back to me after 35 years. They were squirrelled away somewhere in my brain.

Posted: **Fri May 14, 2021 7:46 pm**

Gonna fire up GTK and make a linux GUI for DGDemux. Then gonna seize the bull by the horns and port DGSource.

Sure would like to get audio and the 2080 Ti working. Without those it's hard to take the linux machine seriously.

Can you select NVidia drivers instead of nouveau at install time?

This might? help
