dumpdata issues with NMV extract

[lovedayb]

Hi there,

I know it's been a long time since you have worked on this project, but I'm hoping you can help!

When I try to run the dumpdata script, I have issues with the pff.py extraction, as well as the trailing 'ffmpeg -framerate 1 -i nav-%1d.jpg -r 25 -y -c:v libx264 -crf 22 -pix_fmt yuv420p data/nav.mp4'.

With a bit of work, I managed to get pff.py modified to handle the binary extraction better with the newer python versions, such as using 'read_bytes' and 'write_bytes'. This extracts the jpg files fine.

However, I'm confused about this line:
ffmpeg -framerate 1 -i nav-%1d.jpg -r 25 -y -c:v libx264 -crf 22 -pix_fmt yuv420p data/nav.mp4

The %1d format specifier is confusing - is this line meant to sit inside the previous FOR loop? Or is it only meant to process one of the jpg files?

Any advice would be really appreciated! I'm trying to rebuild the game in another engine such as Godot or AGS but still experimenting and will definitely need all of the hotspots to speed the process up!

Cheers,
Ben

Ok, so I got this working - I had to change the %01d format specifier to %04d as it would not pick up the files that were output with the four-digit suffix.
I had to rewrite the pff.py to properly handle the binary files and the export/dump is generally working fine.
Now I have the same issue as the other guy with the palanca-studio dependency that I need to work through.
Cheers!

Hey, apologies, completely missed your messages but glad you manage to get it to work.

I am not sure the versions of these files are the latest ones in this repo, I need to check on my backups.

Thanks man! Would be awesome if you had anything newer.
I'm starting with the video files, trying to convert them into OGV format so they can be used in AGS, although this format seems to be problematic compared with mp4.

How did you work out all of the node mapping and stuff like how the hotspot files work?

I'm thinking I'll have to create my own hotspot overlays in AGS and script all the navigation and sequences from scratch.

Seems like a lot of work, but I figure it's a pet project and I'm learning something new haha.

Cheers,
Ben

Hi Ben,

I can give you my insights on how the game was build, but there is still an unknown format for me, at least to read the binary which is key for the whole thing, the database HDB files. These contain all the game's metadata and logic, reason I end-up manually creating the nodes :/.
The hotspots are just separate files per movie, but they have generic hotspots (left, front, right) or specific per screen (still images, computer, etc., all inside the database HDB file.)

Hyperbole Studio still have their website online, and they have a demo version of the Virtual Cinema Authoring Tool which can be downloaded here: https://www.virtualcinema.com/
You can at least see a few things from the database but not all.
