SWORD2: PSX: Unhandled Multi-track Video

[sl2365]

I have extracted the RAW stream files from a Playstation 1 IMG file using jPSX.dec as stated in the wiki.

Two files required re-extracting due to errors. But I still get a crash stating this:

generateZipSet: Loaded pack file: shaders.dat
FSDirectory::createReadStreamForMember('stone1.str') -> 'D:\Documents\Games\ScummVM\Broken Sword 2 - The Smoking Mirror\STONE1.STR'
Unhandled multi-track video!
Debugger started, type 'exit' to return to the game.
Type 'help' to see a little list of commands and variables.
ERROR: Unhandled multi-track video!

I asked for help via the forum, and was suggested to post a bug report here.

I get to the cafe in Paris, talk to the waiter then Andre appears. Once I talk about the STONE, he shows it and I assume a cutscene should appear, that is when the game crashes and I get the error.

For whatever reason, this cutscene seems to have the video track indexed as 0 instead of 1. Replacing "track == 1" with "track == 0 || track == 1" on line 210 of file "psx_decoder.cpp" fixes the issue, and it doesn't seem to affect the playback of the rest of the cutscenes.

Thanks, seems simple when you know how!
Trouble is, I don't have a file called "psx_decoder.cpp" where is that? I extracted the ISO file but only get the game files, that doesn't exist. Any idea?

[sl2365]

I assume it's within the Cutscene file PARIS.CLU itself? I've tried extracting that, but I can't.
I then tried looking at the file in a hex editor, but it doesn't show anything regarding track on line 210.
Not sure what else to try.

I'm talking about the source code of the program (​https://github.com/scummvm/scummvm/blob/master/video/psx_decoder.cpp). This has to be done by a developer.

In the meanwhile, to progress in the game, you can just delete the file "stone1.str". Is a very irrelevant cutscene, but you can use MPC-HC, for example, to play it, if you want to see it.

Ah ok, lol thanks for the info, much appreciated.
