donmai-me / wannacri Goto Github PK

I'm working on a reader for the USM files used in Deus Ex Human Revolution, but I kept giving me an error with the format version of the @SFV chunks

I commented out https://github.com/donmai-me/WannaCRI/blob/master/wannacri/usm/usm.py#L187 and https://github.com/donmai-me/WannaCRI/blob/master/wannacri/usm/usm.py#L251 and I got the demuxed video and audio just fine, so I'm wondering if it's important to check for the fmtver key at all.

BTW, I also had to add

        SUBTITLE = bytearray("@SBT", "UTF-8")
        CUE = bytearray("@CUE", "UTF-8")

to the ChunkType enum

Some PS3 games use the usm file format to store cinematics. I was hoping that WannaCRI would be able to mux the extracted files from the usm but found that the the video codec used is MPEG1.

Would it be possible to implement createusm to take raw mpeg1video and an adx file to make an usm file?

Using the official SDK found here, https://archive.org/details/new-criware-sdk you can't open the usms generated with WannaCRI in the USM viewer included in the SDK, might be an interesting thing to investigate.
You can also create official USMs with this tool, which could be useful for reverse engineering purposes.

　Thanks for your amazing works. this tool did work for me on old Criware files, but not recently files

Here is the EMB_AST link(not work with wannacri): EMB_AST

I picked some difference from two files, which worked fine with left, but not right

Here is the error message

 for i, usmfile in enumerate(usmfiles):
        filename = os.path.basename(usmfile)
        print(f"Processing {i+1} of {len(usmfiles)}... ", end="", flush=True)
        try:
            usm = Usm.open(usmfile, encoding=args.encoding, key=args.key)

            usm.demux(
                path=args.output,
                save_video=True,
                save_audio=True,
                save_pages=args.pages,
                folder_name=filename,
            )
        except ValueError:
            print("ERROR")
            print(f"Please run probe on {usmfile}")
        else:
            print("DONE")

I'm not sure if the KEYUSEDIFENCRYPTED is needed?
wannacri extractusm /path/to/usm/file/or/folder --key 0xKEYUSEDIFENCRYPTED

Or, if this file has new encryption, your help will be greatly appreciated!!!

I just discovered that there's a container made by google called vp9. I searched it and Webm contains it which is based from matroska. I tried making webm video files from ffmpeg to create usm files but it doesn't work... What kind of format does it need to create a usm?
(Sorry for dumb question i am new to github.)

Also If it's okay to ask, how's the progress for h.264 videos?
Great work on this program btw 😊

There is too much pog in this repo. Starred

trying to export the .whl file but I get this

I'm trying to create a USM file but I get a mysterious error and I can't create the USM file, the same thing happens when extracting. Thank you

I'm new to installing Python stuff from WHL, but I'm following the steps I can find and am getting an error...

I'm trying to create a USM without encryption .,But there's a problem.
I have already copied files ffmpeg.exe and ffprobe.exe to wannacri.exe folder.
command:wannacri createusm 666.mp4
666.mp4 is a video，My computer can play normally

I've got some errors when a was trying extract usm file and even use command 'probeusm'. File has been created via Scaleform VideoEncoder (CRI Medianoche [NR] Ver.1.70.00 - 2013-03-08) with sample video and subtitles. And video correctly works in game. (Although I had to change the value of the language id in the subtitle chunk so that they are displayed)
I didn't find any mention of the @SBT tag (signature) in the log file.
