I'm experiencing this issue on all 3 of my linux boxes (Ubuntu 8.10):

At some point during large MPG videos, usually about 1/2 way through, skip stops working (long or short skip).

I can reproduce it by starting a video, pressing long skip over and over and usually near the 50% mark, I keep pressing long skip, but it only skips forward about 0.5 seconds.

The interesting thing is that I don't get this problem on more compressed xvid's which take up less space but are the same length.

For example:

4 GB / 120 minutes / MPEG2 --- Problem exists, skipping stops working midway through
1 GB / 120 minutes / MPEG4/xvid -- No problem!

I thought it may be a caching thing, but that doesn't make sense, because I'll skip halfway through a 4 GB mpg then it just stops -- there's no way it cached the first 2 GB.

I also tried upgrading to SVN on one of my boxes and the problem still persists.

I've also tried playing local files to make sure it isn't a network issue, but the problem is there too.

Has anyone else seen this?

Update: I've found now that it always happens at the 50 minute mark (on large mpg's), despite the length of the movie (60/90/120 minutes)

Any ideas??

More likely there's a 32bit variable being used for the offset somewhere there should be a 64bit one. Max you can store in 32bits is a 2GB offset.

Thanks!! -- That makes sense, I'm just surprised no one else has experienced / noticed it? i.e. it's not a "known issue" ?

If anyone else out there has a 3-6 GB MPEG2 that is > 60 minutes long... Try to play it and try long-skip (mine is 10 min increments) past the 50 minute mark..

Should I submit this formally as a bug?

I would expect so, just make sure there isn't one already (There was at some time an existing ticket dealing with large files, might have been FFWD/REW though).

Point to this thread and include AltheKillers comment also.

Found what I believe is the same bug, as a ticket:

Hi MattPF

I have Exactly the same problem at the 50 minute mark...i have been having this for ages i kinda given up on it..

Thx for raising the point again..i really hope this gets fixed soon as i have loads of mpg files from mythtv

Glad to know I'm not the only one annoyed by this

Is there any way we can get the priority of this bug elevated? I'd imagine there a lot of Linux users watching > 2 GB MPEG's who get bothered by it.

Can any of the developers that know stuff about how seeking works provide any further insight as to what we could do to try and narrow this down any further (if that is what is needed to try and find some sort of resolution).

I've just updated the mpegts*.* files within XBMC from today's revision of ffmpeg to resolve another issue. That doesn't seem to have changed the seeking issues though.

It's got to the point that my partner has started throwing the remote at me when it doesn't work. XBMC has also been given some colorful names...

Is there any way to escalate this issue? All of our recordings are > 2 GB and it's such a pain when we hit the 50 minute / 2 GB mark.

I just tested 9.11alpha2 and the issue is still present. I noticed it's mentioned in the known_issues.txt of 9.04 Babylon:

Fixed in 9.11 release branch and trunk as of r25181. Please reopen http://trac.xbmc.org/ticket/6009 if this is still an issue. See also http://forum.xbmc.org/showthread.php?tid=45146.
