Entrypoints and position

[Leehro]

I'm authoring some concert VCDs with entrypoints using VCDImager and XML for the PBC functions. I've created everything just fine, and I'm wondering about this issue:

For example, say I'm watching song 2. I skip to song 4, and let it play through to song 5. If I press next, I get song 5 again, and previous takes me to song 3. The VCD player doesn't know that the stream has played PAST song 4...it just knows where the last entry point was, and what selection it was last told to go.

Is there any way to 'fix' this? So that when an entry selection is played through, the player knows it? I thought maybe it had somethng to do with auto-pause but the XML spec for vcds says you can't do this with selection items...(and I DO use a main menu)

Anyone else seen this problem?

I am having the same problem when I play my home-made VCD on my PC using WinDVD.

In topic Selection vs playlist in XML for SVCD it is suggested by "vitualis" to use selection items i.s.o. playlist items in the PBC area, in order to solve this problem. I also found an XML example "videocd_9.xml" on the VCDImager website, that uses a selection item for each entry point. I followed this example, but I keep having the same problem, that is, with WinDVD. I am unsure if the problem is caused by WinDVD, or that standalone players behave the same.

This issue is UNFIXABLE as it is a limitation in the VCD specs. You will have this problem with whatever authoring program you use.

The only way for the "NEXT and "PREV" buttons to work as they should is to use separate tracks but then they wouldn't be seamless.

As for the post CornelisJ was referring to, that's just so that at the end of the track, it doesn't go to chapter2 rather than to "next disc" or something.

CornelisJ, there is a small error in the videocd_9.xml example it you are going to use it as a guide. For each of the entrypoints, I used a selection item. However, you will note that the <loop> tag has the jump_timing set to "delayed". This should be "immediate" otherwise it will not work on some players.

Regards.
