Status of the project?

What's the status of the project?

I want to change a few properties and drop some others in WEBM files. This project seems to be the most well-suited for the task. The alternatives I found are:

• https://github.com/OlegZee/NEbml — barebones EBML implementation, with Matroska support being a small example project
  • https://github.com/OlegZee/NEbml/tree/dev/Src/MkvTitleEdit
• https://github.com/StefH/Matroska — strongly-typed Matroska stuff, but focused exclusively on deserialization and with tons of reflection; based on forked NEbml
  • Any chance to be able to use this library for writing MKVs ? StefH/Matroska#14

This project, SpawnDev.EBML, supports Matroska serialization, specifically deals with CRC and SeekHeads. However, the main problem is that it's hard to get it to work.

1. I've tried referencing NuGet package. For some reason, my code just couldn't see any types in the referenced library. I couldn't figure out why. No warnings.
2. Tried referencing a DLL directly, same thing. Doesn't work, no errors. At this point I thought I'm going crazy.
3. Added Git repository as a submodule. The version in the master branch references a project which doesn't exist with a relative path.
4. Tried switching to a release version. No tags in the repository, and the commit messages are largely meaningless.
5. Switched to the "good build" commit f5b4b53. Building it on .NET 10 failed because of Reverse changes, even though R# didn't notice any issues.
6. Switched to .NET 10 and fixed whatever the issues with Reverse were. It finally ran.
7. Tried loading document from file stream. Everything broke after I released it. Copied to MemoryStream. It loaded the file.
8. I tried using GetElement method. Found out there's no documentation on how it works. Couldn't find a way to reliably select items I need.
9. Switched to manual traversal. Finally got it to work.

So:

1. Could you please add tags to the commits which reflect NuGet releases?
2. Are there any plans to finish the version in the master branch, which seems to be 3.0?
3. If you have any hints or guidance on my troubles, please share.

Ideally, I'd love a strongly-typed Matroska file support, with your patching implementation, and I can help with implementing it, but I'll need the project to get to a stable state before I contribute anything.

To be perfectly honest, it is, at this time, abandoned. I dove into it hard when my best friend, Minnie (the Pomeranian in my profile pic) died last year after some rough months battling cancer and then I stopped when the depression deepened. (I know TMI... sorry.)

I think version 1.0.3 is the last ("good") version before I did a major, unfinished rework, but I am not positive.

This is the project I have failed the most. I'm sure that is not what you wanted to hear.

@Athari If that's of any help to you, I created a few helper classes to help my library handle MKA files :

https://github.com/Zeugma440/atldotnet/blob/main/ATL/AudioData/IO/MKA.cs
https://github.com/Zeugma440/atldotnet/blob/main/ATL/AudioData/IO/Helpers/EBMLReader.cs
https://github.com/Zeugma440/atldotnet/blob/main/ATL/AudioData/IO/Helpers/EBMLHelper.cs

They work like a charm on real-life audio files. Didn't test video files, but there's no reason it shouldn't work.

@LostBeard So sorry to hear that 😦

@LostBeard

Sorry for your loss.

Okay... How far is patching from actually working? The SpawnDev.PatchStreams thing. Is it abandoned too? That would be a unique feature which is hard to migrate.

Handling of Matroska is frankly very far from my vision of perfect API in all 3 libraries, so I'd be rewriting that anyway.

@Zeugma440

The last thing I expected to see under "atldotnet" is "Audio Tools Library", considering Microsoft Active Template Library exists for almost 30 years. 😆

That code is too high-level and specialized for my case, but a lot of stuff in there seems useful. Starred the repo, thanks for the info.
