Cool. I could mount an iso file as a loop device and then navigate to the ssif file and it plays as MVC on the Pi.
Seeking kind of worked. I get a few second of 2D playback then it switches back to 3D... It does sometimes stall for a few seconds after seeking.
For proper seeking, I suspect that there are indexes into the ssif file.
I think the clpi/mpls contain indexes into the m2ts file, and as the ssif is a remux of two m2ts files, you may be able to add the offsets from the two m2ts indexes to get an offset into ssif file?
If not then I believe the normal way of seeking a non-indexed transport or program stream is binary search and parsing enough packets to get a timestamp. Keep seeking until you hit the desired timestamp. Obviously this will be less efficient than making use of indexes if that is possible.
I do wonder if the demuxer code should be in libbluray. You want to be able to play the ISO file directly, rather than extract the ssif file from the ISO.
